I've never openly made myself available like this to a dude before. But for some reason, I really want you to go down on me."Fuck. I was so hard. I wa... so horny. I was so turned on. And my step-daughter was sitting within about ten feet from both of us, witnessing this entire thing. I wanted this so bad. But was scared to death of what might happen in the after-effects.And my step-daughter made it easy by simply looking at me, shrugging, and saying, "I'd go for it dude. A chance of a lifetime.. “What's wrong?” I asked. “I'm having trouble getting these jeans on,” she said. “Hold on.” I took a peek around. No staff was in the vicinity. I ducked into her dressing room. It had a seat and a hook. The door stood off the ground by two feet and the walls reached up to the ceiling. There were mirrors in the corners by which one could see completely around oneself. My sister was still wearing her black shirt which was getting a bit too tight. She had compensated these past few weeks by cutting. My balls are wet from her squirts, when she had her second orgasm five minutes ago. I kiss her on the neck and run my tongue down to her ear. She has very sensitive ears. I lightly kiss there. I see goose pimples on her naked breasts. She moans and grabs my face back for another french kiss. She speaks "Don't want you to cool down much. I love it when you have to ask again immediately. Start."I am required to comply. I slowly pull my cock out all the way and push it all the way back in. I know. I felt it move deep inside me, again feeling many injections all around my anal canal. I could feel it move deeper inside me, injecting some type of d**g into my body as it moved along. The d**g was taking it’s effect on my body, my nipples were becoming more aroused, hardening, the erotic feeling forced me to begin to play with them, then my pussy began to tingle, that is when I felt Andy start to rub his cock back and forth along my pussy lips. He wasn’t pushing it in, just rubbing it back.
