The Invitation

"Look, it's not so bad," explained Sally. "We had this little problem, and Lucy knew that Mark really desperately wanted to fuck you, and so we just put two and two together..."
"You're gay?" asked Jack, looking at Mark and barely hearing what Sally had said.
"Nah! I'm bisexual. Always have been. I guess you are too now," he smiled.
"Yeah not fucking likely!" Jack shot back.

"Really? Well, when I came in the room you were dressed as a girl and lying on your back with your panties round one ankle while eating out my girlfriend. Meanwhile your own girlfriend was pegging you with a strap on - one, which I might add, has been up my bum more than a few times. It was quite a sight to see, I can tell you. All I did was to take over from Sally and you fucking loved it, as the rock hard erection that you threw up demonstrated. And it didn't take much to make you cum, now did it? Now you have my cum dripping out of your arse as well as drying on your face, because you have also just cleaned Lucy's pussy of the little deposit I left there earlier. Sounds pretty bisexual to me! By the way, you look fucking hot in that underwear!"
