Taking his time

Jon had been gone for only a couple of minutes, but Karen was already beginning to wonder what he might actually be doing in there. "Jon, are you alright?"
"I'm not sure, I think I might be sick or something," came a muffled voice through the closed bathrom door.
"Jon, I think I should come in and see if you are OK," suggested Karen.
"Oh, OK, come right in."
Karen opened the door to see Jon sitting with his dress pulled up around his slim waist, and his hand gently rubbing his clearly wet crotch. 'I'm sorry I was taking so long Karen, but when I got in here I got this itch that I just had to scratch. I don't suppose you would like to help me scratch it, would you?" purred a very feminine Jon.
As Karen's trousers started to tent, she looked the new Jon over. His nipples were definately rock hard now. His face was even more flushed that earlier and he seemed to be having some trouble breathing properly.
"Jon, why don't we go back out to the bedroom to scratch your little itch," suggested Karen.
Without another word Jon stood carefully on his stiletto heels and tring to put a graceful feminine wiggle to his shapely behind, glided back past her, out to the bedroom once again.
When Karen didn't follow straight away, Jon said, "I think my itch is spreading, I really need you to help me soon Karen."
Jon was laying back in the centre of the bed, with his legs spread and his hand gently rubbing his now soden crotch. As inviting as he looked to her, Karen thought, "I'll bet he'd do anything I told him to right now."
"Jon, you really want to answer my questions truthfully, don't you," suggested Karen.
"Of course silly, but can't we talk later," replied Jon.
"Have you ever fantasized about being with a guy? Pressed Karen.
"No, I'm straight, I only like girls, you know that," answered Jon.
"Ok, but for the next half hour you want to act like a really horny girl named Susan who is head over heels in love with her boyfriend, me," suggested Karen.
Once again Jon's demeaner changed. "Oh God Karl, I love you so much," gushed Susan (Jon), spring from the bed SHE lept up into HIS (Karen/Karl's) strong arms, planting a deep, passionate kiss on HIS startled lips. "When are you going to make an honest woman of me?" Susan/Jon teased.
"Right after I make a real woman out of you first," stated Karen/Karl as HE threw the highly aroused Susan back onto the single bed, then climbed lazily on top of HER, rubbing his firm manhood all the way up Susan's silky leg.
"Now what? Karen pondered, "should I go all the way now, or should I make her beg for it? Maybe I should get her to put on a show for the other girls?
