Groggily, I took a chair next to my sister Tina.After work last night, a few of the guys and I went out and partied a bit. I wasn't quite hung over, b...t I wasn't ready for more than just a cup of strong hot coffee.My sister Tina jumped out of her seat and went to fetch my favorite mug. It was one that she'd given me the previous year on my last birthday. The pretty blond model on the side of it loses her teeny black bikini when hot water gets added."We'll celebrate your birthday this weekend.". It felt so dirty to be doing this. I swirled the precum around the head of his penis with my thumb, while at the same time, he spat on his fingers, and rubbed it on my waiting anus. We were both as ready as we'd ever be, so I bent over and put both my hands on the wall, doing my best to tilt my ass up towards his cock. I arched my back.He pushed his cock against my ass hole. I pushed out, relaxing it as much as I could. I've played with myself enough to know that this was the best way to loosen. This part of the assignment should be done somewhere private. Your going to spend time thinking of the sexy female and male qualities. Every time you think of a woman's qualities, like her ass, legs, lips, ect... you will smack, pinch, punch, or flick your balls if you get hard. Then move onto a hot guy... Think about him and the qualities you think could make you want to be his bitch.For example, lets say its muscles... Think about a man and his sexy muscles... I want you to allow yourself to. His cock was bigger than anything I had ever touched. Still on my knees I ran my left hand up Eric’s stomach and chest and straightened up so he could play with my tits.When the first song ended, I switched to Darren’s chair. I fondled Eric and went back to the “fake” blowjob, this time on Darren. Because we had undone his pants, I was sucking Darren through just his underwear. But I wanted more. I worked his huge dick out of his boxers and, against all the rules, I took Darren’s monster into.
