It's all about him, starting with a blowjob

Gary stood up and pulled out his cock. "Get those fat lips around my cock, you dumb slut!"

Jennifer eagerly leaned forward and shoved her mouth onto his wrinkled cock. It wasn't even hard yet, unlike yours. She sucked diligently, then pulled off and stroked him with her hands as she asked, "Would you please not call me dumb? That isn't very nice."

"Shut up and get your mouth back on my cock," said Gary. She started sucking again immediately, and he continued, "You are dumb! You're the dumbest slut I've ever met! You can barely take care of yourself. That's why you need a man to take care of you. A big, strong, smart man like me!"

Would that work? The app was powerful, but could it really change someone's intelligence? You'd have to wait to find out, since Jennifer's mouth was too busy to speak.

"I don't like the talkback, either," said Gary. "From now on, you do whatever I tell you without question. I'm the smart one, and you're just my dumb sex ****. Grab your nips and tweak them if you understand."

Jennifer pinched both her nipples and pulled, letting out a little moan as her big breasts stretched out. It was amazing seeing her big, beautiful breasts jiggle as she worked her nipples.

"Yeah, that's good, just keep playing with those dirty nips. I like that, and you like doing things I like." Gary's dick was finally starting to respond to Jennifer's lips being wrapped around it. Now semi-hard, his cock looked to be a decent size. He turned around and looked back at you sitting on the couch. "What the fuck is wrong with you? This fine piece of meat is putting on a show in front of you, and you're not jacking off? Get to it!"

"Oh, that's a great idea, Gary!" you said. You pulled out your cock, which was already super sensitive from everything you'd seen. You stroked it tenderly, trying not to overdo it. It was hard to slow down with Jennifer on her knees in front of you, sucking a cock.

"Yeah, this is good," said Gary, closing his eyes and letting his head fall backwards. "After all the times the mailman has stolen my mail, after putting up with those stupid whores at the grocery store who are trying to irradiate my balls with their check-out machines, it's finally my turn. I've got the power now, and I'll make them all pay!"

Gary grabbed Jennifer's head and pushed her deeper onto his cock. "Yeah, you like that, don't you, slut? You love the rough stuff! You love the dirty talk! You love it when I insult you! That really turns you on, doesn't it!"

He pulled her off his cock, and the spit and pre-cum dribbled out of her mouth in ropes. She looked up at him and said, "Yes! I love it! Call me your little slut! I'm yours, Gary! You're so hot, I love you cock! Please fuck me, your dirty slut is so horny!"

Gary turned to you and grinned. "Well, what do you think? Should I finish off in her mouth or give the slut the fucking she needs?"
