Rebecca closed the door and waited for her brother. He was saying goodbye to Julie. The vacation had ended and Ben and Rebecca were dropping Julie off at school before they too headed back to their schools.
It seemed to take a long time as she waited and when he appeared in the doorway smiling at her she smiled back. He got in the van and they began the long drive to New York, where both were attending college though technically she was a grad student. The first part of the trip went quick as they talked about the friends and adventures they had and how much they both enjoyed the respite but now were happy to be moving on.
It was just getting dark when they pulled into a rest stop, the last one on the mass pike before the state line to New York. They both went to the bathroom and filled the tank with gas and got a bite to eat. They had decided that they were not going to stop for long so soon they were back on the road.
As Rebecca looked over at her brother she smiled and thought of their first time making love. He was reluctant and they hadn't talked about it for a long time afterwards. She smiled knowing that he too enjoyed that first time as much as she had. She decided to have a little fun now that it was dark and there wasn't much to look at out the window.
She reached over and ran her hand over her brother's crotch; lingering long enough to make him notice. She could feel him begin to get hard as she rubbed his cock through his pants. He grew hard very quickly under her touch and she could feel it straining against the fabric. Then she reached out to unzip his fly. Ben adjusted himself so she could remove his cock from the confines of his shorts easily. Soon Rebecca was stroking Ben's full seven inch cock that pointed straight up as he drove.
He was smiling as neither had spoken since she had begun to stroke him. The lights of the dashboard were just enough so she could clearly see his manhood as her fingers wrapped around his shaft and pulled up and down.
Watching her hand slide over his cock was making her horny so after a few minutes she decided what the hell and she released his member long enough to shed all her clothes and continue to stroke him.
As soon as she was naked sitting in the dark next to him with only the dashboard lights to illuminate her body she felt as though his cock had somehow gotten stiffer. She chided him to watch the road and with one hand on her brothers cock her other hand was now buried between her legs stroking her now erect clit and very wet pussy.
Ben wanted to fuck her badly and he asked her if he could stop by the side of the road but she said, "No."
Something inside her wanted to tease him a bit. She was jealous of Julie and Ben and right after they dropped her off that's all he could talk about. She liked Julie and enjoyed having sex with her but now she was coming to grips with the fact that her brother was falling for her. Rebecca was torn but decided to tease Ben to get back at him for all the talk before. Though he didn't know it he was about to be teased to the limit.
Rebecca could feel the precum ooze from her brother's cock as she slowly stroked him while he drove. Her other hand brought her own cunt to a series of small orgasms. None of which satisfied her lust, they only seemed to fuel her desire. Ben was begging her to stop and Rebecca just told him that, "We are close to my apartment just hold on."
She could tell he was ready to pop anytime so she backed off until they pulled into her apartment building. She threw on a shirt that buttoned up the front of Ben's and ran barefoot with Ben in close pursuit to open the door. She threw on the lights and ducked into the bathroom.
When she came out Ben was lying naked on her bed with his penis pointing straight at her. She smiled and told him to hold on a bit she wasn't ready yet. That did it. It was the straw that broke the camel's back. He stood from the bed and grabbed her wrist and pulled her down onto his lap.
He lifted the shirt exposing her tiny bottom and gave it a few whacks with the flat of his hand. The first one stung the next started to make her clit tingle. Then he lifted her off his lap and put her down on the bed and placing a hand around her throat her grunted at her, "Don't move!"
She was taken aback but not scared; his hand did not choke her just served to tell her he was in charge. She liked this and instantly her pussy gushed and she was now dripping. He then roughly pushed her legs apart and lay down on top of her. She could feel his hard cock laying flat against her mons and belly as he leaned in to whisper to her, "Sis I love you but you deserve what I am about to do so just enjoy it like I know you want too."
He didn't know how much this was turning her on as he now lifted his hips and she could feel his cock slide down her mons and the tip rested against the lips of her cunt. He moved a little to make sure he was aimed correctly and with one big push plunged his stiff cock all the way into her cunt until their hips met.
The swiftness of his movement startled her and when he removed his hand from her throat he next laid down full on top of her and placed his hands under her arms and pulled her to him; holding her tight.
It was if he didn't want her to escape. He held her tight and she could feel his chest compress her breasts as his hips now began to thrust in and out slowly. It wasn't long before he was fucking her hard and fast while holding her tight.
It was in that moment right before she began to have an orgasm that she realized that she really loved her brother so much and she needed to find a way to share him or she would lose him. Rebecca also told herself she should be careful teasing her brother but she was loving the results this time, she had never seen such a temper in her little brother before, If she hadn't been willing she was afraid of what she might have driven him to do.
Right after her orgasm began her pussy once again flooded Ben's cock with fluid and she could sense he was about to cum also. His thrusting was gaining speed and his breathing was rapid and he was making all sorts of moans and groans right before his whole body stiffened and he trust all the way in. She could feel his penis pulse as each one signaled a spurt of jism deep in her pussy and she felt the burning warmth of each one that spread throughout her loins, once again bringing her to another orgasm.
Spent Ben lay atop Rebecca holding her tight and she felt so close to him in that moment. It seemed like an eternity before he made a move to get off her but she resisted, making him stay there. She loved being held so tight during and after sex and she was going to enjoy this for as long as she could.
Long after his softened cock slipped out of her pussy she could feel his cum leaking out onto the bed. Ben arose to go to the bathroom. Rebecca was too caught in the moment to move and she lay there until he returned and lay down beside her with his arm draped over her breasts; watching her measured breathing while she lay with her eyes closed and smiling.
It was two AM when Rebecca awoke to find she was alone in bed. Looking around she found her brother looking out the window. She approached him and said, "What's going on? You OK?"
