Turning away from the wall, I walked across the room with her, intentionally bouncing on my cock with each step, making me moan, until I finally sat h...r up on my desk. I shoved any papers and stuff off, before grabbing her again and pumping back into the sweet, delicious, steamy pussy. The smell of sex was starting to waft up to my nose. Our eyes locked on each others even through the pushing and grinding and rocking. We couldn't keep our hands off each other. Hers were wrapped around my head. His shorts were half off in my excitement and my hands made large sweeping movements from his chest down to his thighs. After what seemed an age he finally reciprocated by holding onto and roughly caressing my hairy forearms. I responded by tugging off his shorts and he completed it by flinging off his already opened shirt. He stood there in front of me in all his handsome, naked glory, a picture of hot masculine virility, a shy, embarrassed smile hiding below that thick manly moustache. I was. With trembling hands, I fondled the public hair for a while as I felt my dick throbbing uncontrollably. I was hesitating to touch the flesh since I didn’t know whether a touch of ecstasy on the pussy would wake her up or not. But I slowly mustered up my courage and went ahead and touched the clits anyways. Boy, it was so soft, and to my slight horror, my sister actually moved a little and spread her legs apart, inadvertently pulling one of her legs out of her panties. The vaginal opening was. And then that thing slid inside. Slowly I moved that dildo up and down. Every time a bit deeper than the last. It slid out and I quickly added some more lube. And also smeared some on my ass hole. I could look at it as I fucked myself, via the mirror on the other side of my brother's room. That looked very horny.I groaned loudly and just wanted to feel more and more inside me. I pushed the monster further and further inside. If I felt a pain, I stopped for a moment. But I did not pull it back..
