We were sent from the room and there was a brief discussion between the her parents before we were called us back in. Permission was granted for Satur...ay night, but there was one condition. We had to take her younger sister with us. June was sixteen and almost a carbon copy of her older sister, expect she was painfully shy. I don't thinks she had said more than two words to me in all my time there. Julie started to protest that she didn't need a sitter and asked the reason for being treated. This did create a bit of a stir amongst some passers by, but I didnt pay any attention as I was 100% focused on not falling over!The sweet guy subbed me in as I had been in such a lather leaving the house as to forget to bring enough cash. We proceeded to the back row of one of the screens and squeezed into the seats - I could feel eyes on me straight away. We started kissing and it didn't take long for me to lean forward and taste his cock. Oh my, he was nice, curved and stiff. How could. “That’s not what you said we were going to do,” I gasped again.“I know, but it feels so good,” she whispered huskily.When I felt the tip slip up into her hair I let myself down on her, trapping her hand between us.“Ohhh Bobby, come on,” she complained.“Let’s try it the way you said,” I insisted.I raised up enough to let her pull her hand out from between us and then experimented with sliding my prick along the folds of her pussy lips. She jerked as the bottom of my long cock scraped across her. Seb and I are both very aroused as we ogle her naked feminine body, tremendous tits, ass and legs and her erection as we watch her settle into a large soft chair. We have never pleasured a tranny as a pair previously and we have hit the jackpot with this one.Without saying a word Seb is on his knees between her legs, licking and and sucking her cock. Then at the very moment he takes her erection between his pursed lips, I slide my erection between her lips. I have had my eight-inch erection.
