Ok Gang here it is, the controversial threesome fic hehe. So this will probably be the smuttiest, kinkiest stuff I've ever written. Also Mandi, thanks so much for sending me Lesbian porn as research, I really appreciate you sending it to me at work with labels stating spread sheets, figures and memos. So when I opened it I had no clue what was going to happen. Especially when I had my speakers on and had to scramble to turn it off before I would have to explain to my boss why my computer was suddenly moaning. So yeah thanks for that I really appreciated it (note the sarcasm cause this message is dripping with it)

Ok so here it is. Kate and Jack are married, it will be AU since Kate in this won't be a complete tool as show Kate is hehe.

HAPPY BIRTHDAY BABY (SERIOUSLY WAS THERE ANY QUESTION ABOUT THE RATING?)

Jack Shephard walked in the front door of his house throwing his keys on the stand and setting his briefcase on the hall table. "Baby I'm home!" he called out so his beautiful wife of five years would know he was home. He was curious there was an unfamiliar car in driveway and he wondered who had stopped by. It was Jack's birthday and he and Kate had discussed just staying in. He worked long hours as a spinal surgeon so when he got home sometimes the last thing he wanted to do was go out when he could just order take out and spend the night with the love of his life. So this morning when they had kissed goodbye they had made plans to just order food in from Jack's favorite Italian restaurant and watch a movie on television.

"Hi" came the sultry sound of Kate's voice. Jack turned and felt his voice catch in his throat. Standing in front of him was his beautiful wife wearing a black silk negligee slip that went to her thighs with a black silk robe.

"Hi" he stuttered as she walked to him he looked down to see she was wearing black pumps that screamed Fuck Me.

"Happy birthday sweetheart" Kate said tilting her head up and catching his mouth with her own and he kissed her back hungrily. She pressed her body against his and he moaned as he felt himself grown hard. He moved her against the wall pressing his weight against her. He had no problem taking her right then and there.

"Wait" Kate said with a smile pulling away from his mouth. "Jack I need to give you your birthday present" she said running her finger down his chest.

"You mean this isn't it?" Jack asked gently tugging on the strap of her lingerie that was peaking through her robe.

"Mmm, it's part of it" Kate said cryptically. She took a nervous breath her and Jack liked to be adventurous in bed but this was definitely the riskiest thing she's ever proposed. "The other part is in the living room" she took his hand and led him down the hall. She led him into the living room where Jack froze. Standing in front of him was a beautiful woman who was looking over the pictures they had displayed on the mantle. She was about Kate's height with long red hair and pale skin. When hearing their arrival she turned and Jack saw she had incredibly blue eyes. Kate smiled and moved in front of him.

"Jack this is Andrea, the other half of your present." She said kissing his lips gently, amused by his stunned reaction.

He looked at her confused, "Kate?" he asked not sure what was happening.

"It's nice to meet you Jack" Andrea said with a disarming smile.

"Uh you too, um Kate what exactly is happening here?" Jack asked focusing on his wife.

Kate giggled. "Andrea is a sexual therapist, she works with couples who need help in the bedroom" she silenced him before he could protest. "She also freelances for people like us, people who have no problems in bed but just want to have some fun."

"Ok," Jack said with a nod and then looked at Andrea, "Can you excuse us just for a second?" he asked, she nodded and Jack pulled Kate into the kitchen.

"We need help in the bedroom?" he asked stunned. Kate shook her head furiously.

"No baby we're perfect in bed. I just thought for your birthday we could do something different. Andrea is a therapist but the only reason why I called her was because she came recommended from a friend. I wanted to give you this and I thought this would be safer than picking up some random hooker." Kate said reassuring her husband that they had no problems in their sex life.

Jack leaned against the table and looked at her, "So for my birthday you want me to have sex with another woman?"

Kate gave a small smile, "Not quite, there will be rules of what you can and can't do with her. Having sex in the definition of putting your cock in her is completely out. You won't be able to do that" Kate said with some force in her voice. "We can talk about the rules out there with Andrea, she suggests rules so no boundaries are crossed and that this remains a fun, playful and sexy experience." Kate said kissing his lips gently. He reached out and grabbed her wrist gently.

"Baby are you saying we're having a threesome and the majority will be you with another woman?" he couldn't believe this was happening.

"Basically" Kate said with a grin. "Are you ok with that? You can have your own rules as well if there are certain things you don't want me to do with her."

"Kate have you ever been with a woman before?" Jack asked curiously.

"Nope," Kate said with a shake of her head.

"You don't have to do this, Kate. I mean I appreciate it more than you'll ever know but baby I'm happy with just you and me and I don't need a third party to make my birthday better." Jack said brushing hair out of her eyes.

"I know Jack, I just thought this could be erotic and fun. It's kind of exciting." She said with a blush and Jack leaned in and kissed her hungrily.

"I will do whatever you want me to do" Jack said when they broke apart.

Kate smiled shyly taking his hand. "I want to do this" she whispered and he gave her a single nod and she led him out to the living room.

Andrea smiled reassuringly at them when they re-entered the room. Kate sat on the couch and Jack settled next to her. Andrea sat in the chair across form them.

"Well let me introduce myself. My name is Andrea Winters and I'm a sex therapist with my PHD in human behavior studies. I work with couples who need help and other couples like you who just want something new to spice things up. As I told Kate when she spoke to me the first time, this experience is about senses, feelings and the love you and Kate share. No where in this involves feelings from my behalf. I'm not interested in relationships with either of you. It sounds odd to say but situations like this can blow up in people's face if they feel their partner may be enjoying things too much. Jealousy can be a dangerous emotion at times like this. That's why I suggest rules; I know Kate you've made some to fit your perimeter of comfort?" Andrea asked. Kate nodded and took Jack's hand in hers.

"I know guys get turned on by woman being with woman so I wanted to do that for you. I want you to have interaction with Andrea but there are restrictions. First you can't enter her pussy with your cock. Second, she can suck on you but you can't come in her mouth. Third, she can kiss you but has to ask for permission first. And fourth I don't know yet I have to think about it but I might allow you to take her anally. I'm still debating on that, I need to see how things go." She said with a slight blush. Jack pulled her close gently kissing her lips.

"I will only do what you want me to do. You call all the shots" he said and she smiled lovingly at him.

"Are there any rules you want for Kate?" Andrea asked Jack. He looked at Kate. "I really don't I just want you to do whatever you're comfortable with. I'm not sure how I'm going to react to seeing you with someone else." He said quietly.

"Just know everything I do is to pleasure you" Kate whispered and they kissed sensually. When they broke apart Kate looked over at Andrea and gave her a smile and a nod. Andrea leaned over and grabbed a bag.

"I bring essentials, such as condoms, KY jelly and some toys as well. With two women and one man I bring this." She pulled out something and Jack moaned out loud when he saw it. It was a strap on dildo. He grew hard at the thought of it being used on Kate.

"You like?" Kate asked amused hearing and feeling his obvious pleasure.

"You think you can handle double penetration?" he whispered huskily and Kate whimpered. She was getting turned on and they hadn't even started yet.

"Perhaps we should get to know one another." Andrea said with a smile. She enjoyed watching the two of them interact they were so obviously in love. Both were so intent on pleasing one another she wasn't worried that unneeded jealously or resentment would be a problem. She knelt in front of Kate and stroked her thighs. She leaned up and kissed Kate gently. It was feather soft but with a little pressure Kate opened her mouth to her and they kissed deeply, their tongues sensually running along each other. Jack watched this his body shot to attention. He had never seen something so erotic as Kate and Andrea kissing. Kate buried her hands into Andrea's hair deepening the kiss and Andrea moaned. Jack watched and grinned when he noticed Kate's eyes were open and was watching him. He reached out and stroked her hair gently pressing her closer to the red head. They pulled apart and kissed gently. Andrea looked to Jack and then back to Kate. Kate gave a nod and Andrea scooted over to him still on her knees. Kate was watching them carefully and he knew this kiss would lay the foundation to how much he and Andrea could do together. Before anything happened he pulled Kate tight against his side and kissed her hungrily letting her know no matter what happened she was his number one priority and love.

He pulled away and felt Andrea clasp his head and pull him down to her gently. She pressed her mouth against his and it took Jack a second to readjust. He hadn't kissed another woman in about six years so it took him a second to get used to her texture and taste. He opened his mouth and she slid her tongue in and he smiled, she tasted like Kate. He opened his eyes and looked over to Kate who was watching him hungrily. Noticing his gaze she smiled and stroked his hair. So far she was ok. Andrea pulled away and looked at Kate. She leaned up with one hand and pulled Kate to her and with the other she pulled Jack. They engaged in a three way kiss that set Jack's body humming. He hadn't done this since college when he would get more than one girl fighting over him. Though he had never had sex with two women at once he had engaged in multiple kissing before. This was better than anything he remembered and he knew it was because Kate was there.

When they were done Andrea looked at Kate, "Would you like to undress me?" she asked and Kate bit her lip and nodded. Jack gently helped her up and Kate went behind Andrea and slowly unzipped her dress. It fell to the floor and Kate picked it up and threw it over the arm of the couch. Andrea stood in front of her in black panties and bra. She also was wearing garters with straps and buckles holding her knee-high stockings up. She leaned over and pulled the belt of Kate's robe apart she pushed the garment away and now both woman we're down to their lingerie. Andrea grazed Kate's thighs with her hands and slowly lifted the garment up and gently gripped the elastic of Kate's panties. She pulled them down and off so Kate was standing there wearing nothing but the silky slip. Kate bit her lip and bravely stepped forward putting her arms around Andrea and unclasped her bra. She pulled it down exposing the woman. Kate felt nervous this was foreign territory to her. The only breasts she had ever touched before were her own.

"Would you like to touch them?" Andrea asked and Kate looked over at Jack and he gave her a slight nod encouraging her. She smiled shyly and gently clasped Andrea's full right breast in her hand. She massaged it gently and tweaked the nipple, so this was it felt like to be Jack she thought ruefully. She touched and massaged the other breast and then took both Andrea and Jack's breath away when she bent and took a nipple into her mouth. Andrea pressed her body against Kate her hands running through Kate's think curls. Kate sucked and nibbled gently at the breast the same way Jack did to her. Andrea moaned and pulled Kate up and they met in a sensual kiss. Kate wrapped her arms around Andrea's neck and they kissed hungrily. She gasped into Andrea's mouth when she felt her probe her gently with two fingers testing her wetness.

"Oh god" Kate moaned and Andrea slipped her fingers deep within Kate's hot and wet center. Kate was used to Jack's fingers which were longer and thicker than Andrea's so it was a new sensation. Andrea slipped another finger in and Kate kissed her hungrily. She was moaning and she gasped when Andrea used her thumb to flick her clit. She felt pressure against her back and realized Jack was standing behind her. She leaned against him gratefully afraid her legs would give out. He reached up her lingerie and clasped her breast in his hands massaging her. Kate moaned at the feeling of being penetrated and having her breasts massaged. Andrea reached around and pulled Jack into their embrace with her free hand. He settled his mouth near Kate's ear.

"How do you feel baby? Is she filling you up? Are you going to come?" he watched as Andrea took Kate's mouth hard as she thrust her fingers harder and harder. Seconds later Kate screamed her body shaking within his embrace and squeezing around Andrea's fingers. She let out a slight moan when Andrea pulled her hand away and Andrea leaned forward and kissed her gently. Kate kissed her back and then turned in Jack's embrace wrapping her arms around him hugging him tight. He hugged her back rubbing her back comforting her as she got her feet back under her. Jack looked up as Andrea stepped up to press against Kate's back and held her fingers out. They were still wet with Kate's release. Kate lifted her head from Jack's shoulder and watched as he took Andrea's fingers in his mouth licking and sucking away her release. She moaned the sight almost too sensual and she buried her face in his neck. She was growing wet again and couldn't believe it.

Jack released Andrea's fingers with a pop enjoying the taste of Kate.

"Kate?" Andrea asked gently. Kate looked up at her. "Can I kiss Jack?" she asked and Kate nodded. With Kate sandwiched between them Andrea kissed Jack hungrily and she could now taste Kate's release with Jack's own flavor. Andrea purred as Jack's tongue entangled with her own. She reached up and stroked Kate's breast while Jack plundered her mouth. He pulled away and Kate quickly replaced Andrea's mouth with her own. Not because she was jealous or felt left out but because she was so turned on for him she couldn't stand it.

"You have too many clothes on" Kate murmured. She pushed him gently back on the couch to sit and exchanged a glance with Andrea. They smiled and both went to work on undressing Jack each taking time to kiss the skin as they exposed it. Soon Jack found him self completely naked and was rock hard. He reached over and pulled Kate's slip up and over her head. She kicked off her heels and was naked as well. Kate turned and with Jack's help they peeled off Andrea's stockings and garter belts and her panties. All three were completely naked and turned on. Kate winked at Andrea and they both kneeled at Jack's lap. Kate leaned forward licking his hard cock like an ice cream cone. She pulled back and Andrea did the same. Jack moaned as both woman worked his cock at the same time. Only pulling away to kiss sloppily with his head in between their mouths. Andrea moved to lick and suck his balls while Kate stroked his shaft.

"How are you baby?" she asked looking at her husband. "Does this feel good do you like this Jack?" she asked stroking him harder.

"God Kate" he moaned as she took him into her mouth while Andrea was still working on him as well. He shifted under them sending him deeper in Kate's throat. A second later he jerked and spilled his release into Kate's mouth and she took him all in happily. When he was done, she smiled wickedly and climbed his body straddling him. Andrea moved to sit beside him. Kate kissed Jack and he pulled away with a jerk.

"Kate" he groaned and she giggled she had tried to snowball him knowing he didn't like the taste but liking to tease him. He lightly slapped her behind and she giggled. She leaned over to Andrea who opened her mouth immediately and they kissed while Jack's release was exchanged between the two women. When both had swallowed they looked at Jack who shook his head at Kate.

"That tastes disgusting I don't know how you swallow." Jack said.

Kate grinned. "You taste wonderful" she said kissing him again, this time with no surprises.

"I have to agree with Kate" Andrea said with a smile and they all shared another three way kiss.

Kate slipped her fingers through Andrea's hair. "Andrea hasn't come yet." She said to Jack who smiled at his wife.

"You want to help her out?" he asked and she nodded and then looked at him shyly.

"Show me how" she whispered. Andrea moaned knowing what was coming. Jack slid off the couch and knelt next to it while Andrea laid back her head resting on the arm of the couch while Kate laid flat on her stomach. She spread Andrea's legs and looked at Jack expectantly. He rubbed her back and spoke to her.

"Take a look at her center is she wet baby?" he asked and Kate nodded. "Ok good, first you need to get a taste, take your tongue and just lick her right up her slit." Kate did and Andrea moaned. "How does she taste sweetheart?" he asked never in a million fantasies did he think he would spend his night teaching his wife how to go down on a woman. Kate let Andrea's taste rest on her tongue. It was different and strange. Not something Kate would want to do a lot but for this moment she enjoyed it. "Now do you see her hole? Gently put your tongue in there, stroke her softly." Jack instructed and Kate did so sending Andrea into a fit of moans. Kate did this for a few minutes thrusting her tongue in and out. She pulled away and looked at Jack for instruction. He took her hand and took her index and middle finger. He pulled them into his mouth laving them with his tongue wetting them.

"Put these in her" he said and Kate nodded and smiled shyly at him. She eased her fingers inside her and Andrea cried out their names. Kate smiled knowing she was causing this woman great pleasure. She thrust her fingers in and out and feeling brave added another finger stretching Andrea who was moaning beneath her. "Suck on her clit" Jack said brushing Kate's hair out of her face so he could watch. Kate gently sucked the bundle of nerves into her mouth and Andrea jerked and came hard squeezing Kate's fingers. Kate licked up the remnants of Andrea's release and then kissed Jack hungrily letting him share in the taste as well. Kate eased her fingers out of her and Jack whispered in her ear. "Let her suck on them, let her taste herself."

Kate moved up Andrea's body straddling her and Jack moaned at the sight of the naked women pressed against each other. She slipped her fingers into Andrea's mouth who licked them clean. When she was done she pulled Kate down and kissed her gratefully for the release. Kate stretched out so she was laying fully on top of the red head kissing and Jack found himself growing hard. Andrea noticed Jack watching them hungrily and she reached out and grabbed the bag. She pulled out the strap on and Jack nearly came right there. He got up and eased Kate back while Andrea donned on the toy. Jack played with Kate gently kissing her while fingering her making sure she was wet. When Andrea was ready Jack kissed Kate and then eased her back up Andrea's body. Kate knelt above her and then lowered herself over the hardened toy. As it slipped inside of her both women moaned. Kate because of the penetration and Andrea because there was a nub that pressed into her clit.

When Kate was fully impaled she leaned down and they kissed passionately and Kate rocked her hips sending them both sparks of pleasure. Kate gasped when she found Jack behind her and he whispered in her ear. "I'm going to take you baby, are you ready for me?" He used the KY jelly to lubricate the tight hole between her buttocks and Kate moaned yes. She had never had any interest in anal sex until she did it with Jack. She adored it and craved it when they were together. He pressed into her slowly and gently and Kate moaned and cried out in ecstasy. Soon he was imbedded as deep as he could go and he bit his lip she was so tight. She was moaning and crying out form the feel of double penetration. She felt so full she thought she'd explode. Jack swore as he could feel the end of the dildo pressing against the thin membrane that separated him and Andrea. Kate began to rock harder and the movement sent pleasure through Andrea and Jack. She moved faster and felt the two of them thrust deeper into her. She felt her self climb to the edge of the cliff and whimpered as Jack and Andrea coincided thrusts. Kate screamed and her body tightened as she came around them both whimpering and speaking words of gibberish. She jerked hard and Andrea came a second later her body reacting to Kate's counter thrusts. Both women collapsed in a heap and Kate reached back stroked Jack lazily. He knew she was getting tired.

He began to thrust hard and Kate moaned into Andrea's neck where her face was buried. Andrea reached up and stroked Jack's face.

"Come Jack come on fill Kate up come for her" she said and Kate moaned at the words.

Jack bit his lip and exploded deep inside Kate and both she and Andrea cried out the force of his orgasm rocking both women.

Jack rolled off of Kate and lay on his side, while Kate remained on top of the red head. The toy was still nestled up inside Kate and Andrea just stroked her hair and back. She looked over at Jack and smiled.

"Kate can I kiss Jack?" she asked and Kate mumbled yes turning her head so she could watch. They kissed lazily their tongues rubbing against one another. Kate sat up fascinated by the two kissing. Any other circumstance Kate would claw a woman apart for just thinking about kissing Jack but here with Andrea still embedded in her with the dildo her hands stroking her hair and Jack's arm around her waist, she felt no jealously. Kate eased off of Andrea and the toy. She knelt behind her and watched as Andrea moved closer to Jack. Jack's eyes were opened and watching Kate, enjoying the kissing but waiting for her to make the next move. Kate took Andrea's hand and brought it to Jack's cock.

"Stroke him" she ordered and Andrea did working him up and down. Jack moaned against Andrea's mouth as her talented hand started to harden him again. Kate brushed the hair out of Andrea's eyes and the woman broke form Jack's mouth to look at her.

"Can you come again" Kate asked and Andrea nodded. "Good let's get this off" she said unclipping the strap on. Kate moved it and secured it on herself. She had never worn one before so it took a second to get used to. She settled it on her clit and then lay on her back. She motioned for Andrea to climb on top of her. She then looked at Jack.

"Take her baby, take her hard" she whispered. Jack frowned slightly.

"Are you sure?" he asked gently not wanting to upset her.

"Yes, take her anally; you just can't come in her." Kate whispered. "Would you like to feel him in you?" she asked Andrea. Andrea looked at her and seeing Kate was ok with the situation she nodded. She climbed on top of Kate and lowered herself on the way Kate had done earlier. She watched as Jack reached over and grabbed a condom and the KY jelly. Kate smiled glad he was using a condom with her. And then he readied her with the jelly.

"Are you ready?" he asked both of them and they each replied yes. He eased slowly inside Andrea's tight hole and she whimpered at his penetration.

"Oh god, oh god, Jack so deep" she whimpered and that made Kate smile she was glad the red head was being pleasured. She gasped as Andrea began to ride her and the toy pressed her clit. Jack thrust in and out though he never took his eyes off of Kate who grinned at him. He could feel him through the other woman and it was a feeling of deep connection. Jack leaned forward and kissed Kate hungrily his change of position sending Andrea into a moaning fit. Kate thrust up hard, and Andrea came hard screaming incoherently. When she collapsed Kate and Jack made eye contact. Jack pulled out of her ripping the condom off while Kate rid herself of the toy. The couch was wide enough that Andrea could lay on her side and recover while watching the couple. Jack pulled Kate tight and sank deep inside of her making her cry out his name.

"I love you Kate, oh god I love you" he said thrusting into her hard. Kate moaned and wriggled beneath him wanting him to take her harder. As if reading her mind Jack began to hammer her.

"Oh Jack, so good, so good. You fit me perfectly. I love you, I love you, I love you" she proclaimed. Looking into each others eyes and feeling nothing but love for one another they came together, Kate squeezing him tight within her while he spilt his release inside her. The collapsed together and Kate held him close wrapping her arms and legs around him while she stroked his back. "I love you" she whispered into his ear

He sat up and looked at her with such affection her heart melted. "I will love you till my dying breath" he said and they kissed gently. Andrea smiled watching the two knowing they were the real deal. She scooted off the couch and smirked as her body twinged with the after effects of the love making she partook in. she slipped her panties and dress on throwing her bra and stockings back in the bag. She threw the condoms, jelly and strap on back in the bag. When she was done she turned to see Kate and Jack sitting up a blanket covering them. She knelt in front of Jack and looked at Kate. Knowing what she wanted Kate nodded and Andrea kissed Jack sweetly goodbye. When she pulled away she moved to Kate resting her arms on Kate's thighs.

"Thank you for inviting me over, you and Jack will be together a long time, I can tell." She said and then kissed Kate softly goodbye. Then she got up and with a smile and wink to both of them she let herself out. Jack leaned back against the couch and watched his wife.

"What?" she asked noticing his stare. Jack grinned and pulled her onto his lap kissing her deeply. "Happy birthday baby" she whispered.

"You are incredible you know that?" he asked. "My god baby the things you do to me." He kissed her again.

"I had ulterior motives" she said stroking his cheek. "I wanted you to experience this now because I will never share you again, this was a one time deal."

"That's fine with me" Jack said rubbing her back as she snuggled into his arms.

"I also did this because my birthday is coming up and I want something special" she said and Jack stiffened.

"Please don't say another man" Jack said startled and Kate giggled.

"Nope I wanted you to have this experience before I ask you to settle down and sew your wild oats. For my birthday I want to make a baby" she said sitting him up to look into his eyes. Jack looked at her and felt a happiness he couldn't describe rush through his body.

"Absolutely" he whispered and she looked at him with happy tears in her eyes.

"Really?" she asked and he nodded. "Oh Jack" she threw herself into his arms kissing his face and neck with happy tears streaming down her face.

"I can't wait to make a baby with you" Jack whispered and they held each other into the night happily planning their future.

Ok so seriously let me know what you think. Was there enough Jate love? Tell me your opinions :)
