I look over at her. Her eyes are wide as I am attaching the handcuffs. I then lie on my stomach close to Amber and put the handcuffs on my wrists. She... is making wild noises now as the last handcuff is locked around my wrist. I then pull my cuffed ankles up close to my to my wrists. I reach around until I finally locate the pair of handcuffs that are locked on between my ankles. I lock my wrists to my ankles and look over at Amber. She lets out a whimpering sigh. "Oh shit!" I forgot all about. She slowly unzipped my jeans and reached in to my boxers, pulling out my cock and wrapping her warm fingers around it. She slowly stroked the length of my cock, gently rubbing the head between her fingers. If I didn't know about the loud echo in the garage I would have let out a moan right there. It was dark, but people might still hear us. She was furiously working my dick with her expert fingers as I lost myself in a deep passionate kiss. But with cars parked all around us I knew that we. I put that idea aside and went up to my room to do my homework and some of the extra work they had suggested. Then, about five-thirty, I took my homework down and Mom and I sat at the kitchen table while she looked it over, checking every bit.I was nervous, of course, for one, she might not accept the work I'd done. Or, maybe I'd hear her say that she wasn't going through with this after all.She finished the last page, it was algebra, something I was close to failing, and looked up at me, then. As she was not conscious it felt hard to penetrate, but after few strokes, I moved it in and started stroking in.I was fully on top of her and started sucking her boobs again and pumping her pussy down. The one which belonged to my brother is now mine too. I could sense her breathing and moaning and increased my speed. I felt my cock fully inside her and after 15 mins I felt that I am going to cum.As my cock was fully inside her, I could not take that out easily and cummed inside her pussy.
