Justin isn't pleased

You hear the shower turn off, both you and Ivan anticipating what's to come. After a wee bit of time, Justin opens the door, adorning only a towel around his waist. He is taken aback by the scene before him, before growing upset.

"Ivan, what is this?" he asks, clearly annoyed. "Who is this man?"

"Justin, my dear," he says, almost sounding excited, "I've gotten you a small gift."

"What do you mean?" he asks.

"You can have sex with this man." Ivan says, as if that's a normal thing to say.

Justin looks between you, looking unsure whether to laugh or yell. He stares at Ivan, who is on the cusp of a grin, before turning his attention to you.

"I don't know what you've done to him-"

"Justin," you say, speaking for the first time, "Ivan is a cuck. He's just trying to live out his fantasies."

"What?" Justin asks, growing exasperated.

"Ivan gets really horny when you are fucked by other men in front of him." you say.

"No he doesn't!" Justin yells.

"It's true, Justin." Ivan speaks up, "I really want to watch you have sex with this man."

Justin looks horrified. Before he can say anything, you speak up.

"In a healthy relationship, partners try out each other's kinks." you say, "I think you should try out Ivan's kink and you might find you like it."

"I'm not going to have sex with you." Justin says.

"The more you deny it, the more I think you're compensating cause you really do want to do it." you say, hoping this will trap Justin.

"No, I don't want to." Justin says.

However, you arch a glimpse of a throb from beneath his towel. You smile.

"Are you sure Justin?" you ask.

"Yes, I'm sure." He says defiantly.

"Are you sure you don't want to see my big dick?" you tease.

"Yes."

"Are you sure you don't want to stuff your face with my meat?"

"Yes."

"Are you sure you don't want me to fill that cute butt with my cock and pound you till you cum?"

"... yes."

Justin's eyes were beginning to glaze. His cock was now hard and the towel was nearly undone. You can just imagine what was swimming in his mind.

"Justin"

"Yes..." he groans, focusing on you.

"Do you want me to fuck you?"

Justin moans, his dick jutting and making his towel fall. He stares at you hungrily.

"Yes!"
