Later that night

When Karyn got home from school, Jon greeted her at the front door, taking her back pack and bringing her to the living room for her afternoon foot massage. Karyn was in heaven as he stroked her feet, relieving all of the tension of the day.
As she was relaxing, the door bell rang.
"That must be Steve. You stay here Mistress. I'll bring him in." With that, Jon went to the door.
"Steve?" though Karyn. What's he doing here.
A minute later, Jon brought Steve into the living room, wearing nothing but a slave collar of his own. Karyn eyed his well muscled body and noted that his cock was nice, but not nearly as big as Jon's.
"What are you doing here?" she asked.
"I come here once a week to pleasure you. That was the deal you made with my Mistress Sarah. You have me for one afternoon, she has Jon for the next. Have I displeased you? Should I leave? Tell me what to do Mistress!" He looked anxious and nervous, as if he had royally screwed up. He was nothing like Steve "The Stud" Farber from before she made her wish. It was a big turn on to see him like this.
"Don't worry about it, Steve. I just forgot. So, what do we normally do?" she asked.
"Well, you usually have Jon eat you out while I massage your shoulders, followed by me fucking Jon while you watch, and shooting my load all over his face. This usually gets you excited enough that Jon pleasures you while I watch and come all over my stomach. Did you have something else in mind this week Mistress?"
That sounded weird to Karyn, who didn't in fact have much sexual experience. Strangely enough though, she found herself getting wet at the thought of being pampered and then getting to watch Jon get fucked and finally get a huge facial from the guy who used to be the biggest straight stud in town.
"Sounds good to me. Lead the way to my room, boys."
