They had decided to study at Lucas'. His mom and sister would both not be home for the weekend, being on a mother daughter retreat. It was thankfully a Friday, and Riley had told her parents she would sleepover at Maya's. Thankfully, Maya knew it was a cover up for the Riley and Lucas to study together without Cory freaking out over his little girl being alone with a boy. Though this was Riley's first lie to her parents, and she wasn't sure if the butterflies in her stomach were from Lucas or her first lie.

They set their stuff down on the coffee table, and Riley opened up the book to the first set of questions. As she asked Lucas question after question she could tell he was getting bored. "Riley, this is getting boring." Lucas whined. Riley rolled her eyes. She wanted to at least get some studying in. The class was her worst class being science.

"How about every time you get a question right, I give you a kiss," She asked him. Lucas smiled at her cute way of getting him to focus. "On the cheek." She finished, and the boy's smile fell a bit. He slowly nodded and continued to answer her questions.

At one point, Lucas quickly turned his head and caught Riley on the lips. She giggled at his persistence. Soon, the correct answers got little pecks on the lips. Then Lucas and Riley stayed there. Their lips meshed together perfectly like they were meant for each other. Lucas soon slid his tongue over Riley's lips asking for entrance. She complied and their tongues fought for dominance. Lucas won, and his tongue explored her mouth, loving the taste. Riley started to moan a bit, and Lucas loved the sound.

Riley's hands seemed to be looking for the hem of Lucas's shirt. Before she could get to it, the girl parted her lips from her boyfriend's. He frowned at the warmth now gone.

"Lucas," she panted. "I'm ready." Lucas's eyes widened at the sound of those words. His eyes looked into hers with questioning, but were only met with her determined look. He knew she wouldn't back down. They then continued to make out with a new ferocity. Riley finally did find the hem of Lucas' shirt and threw it to the floor.

"Bed now." Lucas told her parting for the slightest moment. Riley nodded and smiled against his lips. Lucas then picked her up, Riley's legs were wrapped around his torso while they kissed clumsily making it to Lucas's room.

-Smut warning-

The blond boy threw the brunette girl onto the bed. She gave a little whoop as she fell. Then they attacked each other viciously. Riley ended up straddling Lucas as they kissed and he threw her shirt across the room. Then Riley was on the bottom as Lucas kissed her neck, and massaged her breast. She let out a loud moan, and the couple was even happier that no one was home.

Not too soon after Riley's bra was off completely. Lucas looked at her in awe. He knew she was beautiful, but now in this light she looked stunning. Then his kisses slowly trailed up and down her exposed torso while he grabbed her breasts. Riley moaned as Lucas went to suck on her exposed nipple. It completely made her feel alive. Riley's hands searched for the belt on Lucas's pants to take them off quickly. He helped her a bit as they continued to kiss, the fire between them growing.

Riley eventually got her boyfriend's pants undone and threw them off of the side of the bed. As he continued to make her moan while he softly nibbled on her breast, her hands ran up and down his toned abs. Soon Lucas's lips found hers again, and he pulled her hips towards his. Riley bucked a bit as she could feel something beneath the fabric of Lucas's boxers. Lucas smiled behind her lips as he undid the buttons on her pants.

The pants ended up in the same place as all the other clothes in the room. On the floor. Lucas's head started to go down south back to Riley's breasts. He nuzzled his face into the crevice between, while she kept bucking her hips towards his. He held her at bay as his kisses trailed down her stomach. His hands not leaving her breasts for a moment.

Riley's hands seemed to be traveling down from Lucas's abs to where his underwear was. She quickly did away with the thin fabric, and looked at him. She had never done this with any one, and she was extremely excited. She continued to grab onto him as he kissed her stomach. Lucas moaned, and it was now Riley's turn to smile in triumph.

Soon Lucas's kisses came down to her skimpy thong. He ran his hands over the area and Riley bucked even more. She moaned as he threw away her lacy underwear and began to feel his hand around inside of her. She bucked her hips as Lucas started to kiss her there and lick a bit. Riley moaned his name over and over. For a split second Riley opened her eyes, and Lucas knew what to do.

He softly slid into her, and she whimpered. Lucas stopped thinking he had hurt her, but the look she gave him told him otherwise. He then continued to go deeper and deeper into her. She smiled and moaned and bucked her hips. Lucas was excited to go this far with the girl he loved. Riley and Lucas moaned simultaneously as Lucas began to thrust. It started out slow, but became more powerful with each and every one. Riley shouted his name and how much she loved him, and Lucas did the same.

With each and every thrust Lucas could feel he was getting to the breaking point. He went even faster and harder, and Riley's moans became even louder. Soon Lucas couldn't continue and he felt something like sparks go between. He fell next to his girl on the bed. They panted almost exactly with each other. Riley turned to look Lucas in the eyes.

-Smut over-

"I love you." She whispered kissing his lips tenderly.

"I love you too." He replied. Then Riley turned over to let Lucas spoon with her. The fell into a deep sleep knowing hours later they would start again. They also realized they could never be with someone else ever again.
