Alex goes farther.

She could feel Sarah try to melt into a puddle of humiliation beneath her, but Alex's grip was steady, and her free hand was again at Sarah's pussy.

"Look at how hot Michael is finding you slut. His cock is practically throbbing watching you being a horny little slut for me." Sarah moaned again underneath Alex's hands. Obviously, the humiliation wasn't detracting Sarah from being horny. She could even feel Sarah rubbing against her hand. In fact, the humiliation seemed to make Sarah even more horny. She looked over at Michael again, absolutely hammering himself with his fist, jerking that worm between his legs.

Alex could see that Michael was getting close to orgasming, and that wasn't going to do, so she let go of Sarah and walked over to him. She grabbed his chin and stole a kiss in front of Sarah. It wasn't their first kiss. She had made sure that happened during their first meeting as a "test" of compatibility; at least, that was her justification, but it was their first in front of Sarah.

While they kissed, she gently took hold of his wanking hand and moved it to her butt, feeling him squeeze her cheeks as the kiss turned into a French kiss. With her dictating the motion and length. She broke off the kiss when she had enough, and their eyes met.

"Are you ready to fuck my slut?" Michael wet his lips and nodded. He had been more than ready for the last couple of minutes. Alex grabbed him by the hand and pulled him to his feet, dancing around him so she was leading him from behind. They could see Sarah's lips trembling, and a small pool was forming beneath her.

"What do you say, babe? Doesn't she look so fuckable right now?" she saw Sarah wince at the babe part.

"Yes…" Michael's voice was dripping with arousal.

"Yes, what, sweetie?"

"Yes, babe." Alex smiled. She had insisted on doing some roleplaying with Michael, and making him play her boyfriend was the perfect thing. Alex thought, firstly it would make Michael more amenable. I mean, who wouldn't do anything for their girlfriend? Secondly, it would totally humiliate Sarah to have to play the third wheel for once.

"Better." She kissed him on the neck and shoulder as a reward. Looking over his shoulder, she commanded.

"What are you waiting for slut? His dick is right there." Alex grabbed Michael's dick and gave it a couple of strokes to emphasize it. Sarah leaned forward slowly, still feeling self-conscious about performing sexual acts in front of Alex. But she did as she was told, and seconds later, the lovely sound that was produced when a person performed oral on another.

Alex let go of Michael to return behind Sarah. Her submissive girl was doing her best, taking Michael into her mouth. Alex helped slightly by pushing Sarah that little extra. Alex looked up at Michael's lust-filled face.

"How is my little slut doing, babe? Is her performance acceptable, or does she need more training?"
