"Wait a second" said Mary "Whoever gets the cock, Katie is just wrapped around it, totally helpless and subservient, just a sexual aid?"
"That's it" said Jessica.
"Considering I spent time up her butt, back when she had a butt, I think it's my turn. I always wondered what it was like to have one anyway."
"You wanna be a guy, or you just wanna have a cock?"
"Fuck no I don't wanna be a guy, but I don't mind being a hung girl. Not with little Katie as an accessory. Don't worry, I'll treat her right."
"Alright" said Jessica. "Two conditions."
"What?"
"First is take off your pants so we can watch. I'm going to time this one slow."
Mary grimaced. "Perv. OK, whatever. What's the second?"
"Once you've got it, don't leave the toilet seat up."
Mary was already pulling her pants and underwear off. "Make it a big one." she said. "If I'm going to fuck guys with it I want them to know they've been fucked."
