Dear Kim,we love you really much. You're our BFF. Love,Grace and Bodi .

Kim smiled and opened the present;tears ran down her cheeks. It was a picture with them at their last photo shoot. They were pulling faces. They had so much fun. She smiled and opened the other. After 30 minutes, Kim finally reached to the last present. She smiled.

"Jack..." Kim said.

"Open it Kimmy!" Kim smiled and opened it. It was a beautiful necklace who looked like a heart. Kim smiled and hugged him.

"Thanks Jackie! Can you put it?" Jack took it and Kim kept her hair so Jack could put it; after he do it,Jack started to kiss the back of her neck. Kim moaned at this,making Jack hard. Kim turned her head and looked to see Jack's beautiful eyes black with lust. "Jack,remember what you promised?"

Jack smirked and took Kim in bridal style and ran to his room. He closed the door and put Kim on the bed,starting to kiss her slowly. Kim reached to the hem of his shirt and tried to take it. Jack pulled away and tossed the shirt somewhere in the room. Jack leaned then kissed slowly her neck,making her wet.

Jack reached behind her dress and started to unzip. She sat up and let Jack to take of her dress,leaving her in a pair of pink lance panties and a pink lance bra. Jack stared at her and she blushed. Jack kissed her. "It's ok baby-girl. You don't have to be ashamed." Jack said,then kissed her again.

"Don't call me baby-girl. Now I am a women." Jack laughed then kissed her again;Kim's hands travelled to his jeans,taking them off. Jack helped her by throwing them,then Jack started to kiss her cheeks,then neck,then the top of her breasts. Kim moaned and fisted his hair,making Jack growl.

"Can I...?" Jack asked. Kim nodded and let Jack to took of her bra,showing him her C+ cup breasts. "Wow..." Kim blushed,then watched as Jack's mouth came on her nipple,sucking it slowly. Kim moaned,fisting his hair more.

Kim let a little scream as Jack nibbled her nipple,then lick there. Jack took of her panties,rubbing his fingers by her clit. "J-Jack..." Kim moaned,then reached to his boxers,taking them off.

"Wow..." Kim said as he started amazed at his hard 15" cock. She slowly stroked it,making him growl. Kim stroked it faster and Jack growled louder. Kim kissed him,then pulled away. "Jack,I need you in me. NOW!" Jack nodded then laid Kim on her back,separing her legs.

"Do you think that we should use a condom?" Jack asked.

"No. Yesterday I took my pills and they least 3 weeks." Kim said. Jack smiled and kissed her again;after he pulled away he saw fear in her eyes.

"Are you ok? If you don't want to,then..." Kim put a finger on his lips.

"Jack,I'm ok. It's just...i-it's suposed to hurt." Kim said. Jack looked at her,then kissed her forehead.

"How do you want me to enter you?Fast or slow?" Jack asked.

"Fast." Kim said,her eyes closed. She wanted the pain to leave fast. Jack nodded and got into a comfortable position,then enter in her fast. Kim screamed when he broke her himen,tears falling from her eyes. Jack kissed her tears and stroked her cheek.

"It's ok baby. The pain will leave." Jack said. After 1 minute,Kim nodded and Jack started to go in slowly. It hurted at first moves,but then the pain turned into pleasure.

"Faster." Kim moaned;Jack moved a little faster. After some seconds his thrusts began to be more wild,making them both moan. " Harder! Deeper!" Jack started to kiss her neck and moved in her really fast and really hard,hitting her g-spot. "Oh,yeah. J-Jack."

Jack lowered his head,stopping to suck her breasts,thrusting in her harder. Kim grabbed the sheets,moaning loud.

"Kim! Augh! I'm about to cum!" Jack moaned in her ear.

"Me too!" Kim said. After some wild thrusts,they both came screaming each other name. Jack kissed Kim a little more,then collapsed next to her,pulling her to his chest.

"Wow!" they both said,smiling.

"That was the best sex I've ever had." Jack said,kissing her.

"You had sex before?" Kim asked.
