Derek scrambled to hide her shirt and panties then cover himself with a blanket. He had just mashed a pillow with his head when the bedroom door opened. “Derek? You still awake?” his mother asked quietly. “Huh, oh, yeah mom, I just went to bed.” “Where is your sister, she isn’t in her room?” “She was with Patty and Gwen earlier, maybe she left somewhere with them.” “Okay, good night dear, I love you.” “Love you too mom.” The door japanese eased closed again. It was a full 30 seconds before Mandy peeked over the edge of the bed at the door, “Did they go to bed?” she whispered. “I think so, come up, you asian can probably go back now.” Mandy eased cautiously up to the bed then lifted the blanket and slipped in beside her brother, “Not yet, they might still be walking around.” When she settled in her legs were rubbing against Derek's, she put a hand on his chest. “I’m going to stay here for a while.” Since his sister small tits was lying close, Derek rolled to face her, he pressed his groin against the junction of her thighs then put an arm around her waist, “You can stay here all night if you handjob want.” She didn’t respond to the statement but asked “Did you cum in me?” “Uh, yeah, you didn’t stop me so I Hardcore did it. Are you okay?” “I don’t know, I think so.” She didn’t feel as concerned as she thought she should that her brother just turned loose a few million sperm cells in her. “It’s too late to say no and I won’t worry right now, I’ll do that if I don’t start on time.” They fell quiet, looking at each other, each trying to evaluate how they felt about what they had done, how to deal with their incest; how to behave as brother and sister again. After a few moments of quiet reflection it was Derek who suggested they smoke another bowl. “Aren’t you tired?” she asked. “Well, if you want to sleep I guess we don’t need to.” “Hey, I didn’t say no.” she grinned. The pair got out of bed and went to the floor next to his window, the night was warm so they didn’t feel the need to don any clothing or robes. While she packed the pipe he opened the window then brother and sister lit up again. The conversation was quiet, causal as they drifted on a cloud. They weren’t being suggestive, teasing or hinting for another sexual encounter, they were siblings enjoying a non combative sibling moment. Some fifteen minutes after sitting at the window Mandy said she was uncomfortable, her legs were getting sore from sitting on folded knees. As she lifted up Derek straightened his legs and sat back against his bed, leaning on it, legs stretched across the floor. Mandy looked at his position then shifted around so she was sitting on his thighs then leaned back on him, her knees relieved to be straight again. He put his hands on her hips then pulled her butt tighter against his groin. She jostled her hips as a vampish taunt then relaxed back on him. Derek reacted to the girl on his lap in the only way nature can. “Not sure,” he responded, “I was hoping they would come out after we got in the pool but I asian don’t see any sign of them except at the kitchen window. On Monday, at lunch Nancy and I had our regular study and lunch meeting, she betrayed no knowledge at all of my date with Abigail. After they came down from their orgasm they both got on their knees in front of him waiting for the next order " okay clean up this mess we made after that mom will change in her best lingerie and laurien will help her if needed then we shall see what we will do with the rest of our saterday " he says looking down at them they both nodded and started to do their tasks . “Amy…what the hell do you think I was thinking about? "I was afraid that if it leaks out then we will loss our pride in the society and there is no way except suicide of the entire family. Becki’s eyes flashed wide. He preferred the way she tasted after she shuddered, small tits so he'd lick harder and faster until she did. “Oh hush, I haven’t handjob even gone in yet.” My sister spit on the dong and rubbed it around. Kathy said: "Oh(Squirt) God(Squirt) Alan(Squirt) I'm Cummmin...I reached around and shoved my finger in her pussy and drug it across her clit on my way out..then in circles, she went in to a slow guttural moan and said to me Hardcore everytime I hit bottom...."Im.....Cummm innnn"...."im cummm innnn" She sat on the counter while I nursed her nipples back to hardness. I hugged Mommy tighter, my hands grabbing her japanese rump.
