His eyes were shut in sleep when he felt a mouth on his cock. It was being sucked in between full luscious lips into the warm wetness of a mouth as it moved up and down his cock. They shot open with such force that it felt like his eyes had crashed into his eyebrows. After getting his bearings from his lying down position, he looked down the front of his body in the dim light of the bedroom to see a mass of dark hair moving up and down. His body was arching to meet the motions of the warm wet mouth as a tongue massage the length of his cock. He was in heaven! Then he felt fingers stroking his balls in rhythm with the mouth that was on his cock. Reaching to bury his fingers in the dark mass of hair and fought that his arms and legs were tied to the bed posts. Noticing that he could free himself if he tried, in the same instant realized that it was to remind him of his submissiveness. It was his turn to lay there enjoying the pleasure of being taken. Then those fingers found the spot between his anus and balls and started to dance on it. He went from moaning his pleasure to screaming as the mouth on his cock sucked harder at him. Sweat was now pouring off his body, getting his eyes making it hard for him to see, so he closed his eyes and gave his vision over to the areas of sexual sensation that his body was experiencing. It was then that it started, his orgasm, like a slow moving river of fire that was making a hot situation hotter, he thought until those fingers found his asshole and entered. They now were keeping time with the sucking of his cock, and he was losing his mind from the pleasure that he was experiencing. With his blood roaring in his ears being driven on by his orgasm, he knew that to be submissive any long would be too much. As he started to free himself the mouth and fingers stopped and withdrew leaving him in a state of cumming without an anchor in the storm that was his orgasm. He came hard, shaking, and screaming her name as a curse and a blessing. In the process, he became aware of that he was no longer tied down.
When he could focus and catch his breath, he found himself lying in the ruins of his bed, covers on the floor along with the pillows and the top mattress halfway off the bed. Too deep in the comfort of the afterglow to move he laid there and fell into a deep sleep, but not before feeling the presence of a warm body curling up next to him. He could feel the soft fullness of her breasts as she moved to lay her head on his shoulder and to place a soft kiss on his collar bone.
They laid there in the wreckage and the pleasure of afterglow, saying nothing with their eyes closed listening and feeling each other breath.
As daylight crept in between the curtains, he opened his eye s and looked down at the dark mass of curls that still covered the bowed head of the owner of the mouth and fingers that had given him so much pleasure. He didn't need to see her face he had been admiring it for a while since the day his father brother her and her mother to his house to be a part of their family as his step-mother and her as his step-sister. He knew that one day their parents would have to be told, but right now it would be their secret. Find the strength he carried her back to her bedroom knowing that his parents would be returning from his father business trip later on that morning.
Brushing the dark mass of silky curls from her face he now could see the beauty that had to capture him the day they met, full lips, with large doe like eyes that were the most hypnotic shade of golden brown that glowed in her naturally tanned face. Those eyes were closed now in sleep as he laid her on her bed. He now could see and feel her hour glass figure invited unwanted attention and comments from others. He didn't like it but to keep their secret he had to play if from a step-brother's point of view.
She seemed to glow against the white sheet of the bedding as the sight of her caused his cock to harden and his mouth to water. It had been a while since he has tasted her. Ok, yesterday before his friends came over and she had got out with her friends from college. He had eaten her pussy until she was screaming and crying his name at the same time. Then he took her up to her bathroom and played with her in the shower, teasing but not taking her to the edge. He wanted to give her something to remember while she was out with friends around boys her age of what she had at home waiting. So as he drank his father's best Scot with his friends as they sat around discussing sports, work and other things he thought about his step-sister. The thought returned him to the present and he dived between her legs parting the lips of her pussy with tongue and fingers in search of her nub. Finding it, he latched on as she came awake with a moan escaping her lips and her back arching pushing her tits with their dark nipples up into the air. She gripped his head with between her thighs as she grabbed the headboard of her bed to hold on to as he did a return performance. Circling her clit and then flicking it rapidly with his tongue he had her shaking and begging that he put his fingers inside of her. It had been agreed upon that they would go no further until her birthday next month. The very thought of his cock inside her had almost stopped him in his tracks this evening when she returned, and his friends had left. All it took was a look of longing from her and her having been on his mind since she had left for them to end up in his bed.
Oral sex had been their major sex act of choice in the 69 formations, and it became all mouths and tongues with fingers to round out the act. They had gone at it for hours sucking, licking and drinking each other in only to fall apart and come back together again. Now here he was again but this time wanting so badly to take it to the next level, knowing that their time was running out.
She came with him between her thighs, his tongue beating out a rhythm on her clit as he massaged her right breast while sucking on the nipple of her left breast. As she withered and screamed his name as her orgasm rode her, he stood back and with his cock in hand as he jerked off spray her still spamming body with his cum.
Moments later after covering her sleeping form with a sheet and blanket, he staggered out of his room and back to the wreck that was his bedroom. With what strength he had left he righted the room and fell back into bed just as he heard the front door open.
"Kids, we're home"...
He closed his eyes thinking, that was close.
