Jennifers ass as the price

"The price, right" Jennifer seemed so distracted by your cock, that she almost forgott about the alledged competition. "Uhh.."

As she didnt seem sure on what an appropriate price is, you decided to help her out.
"Well, I dont think I should just fuck you."
Just as you thought, saying it alone made Jennifer and Marcus flinch. It was to early for that. Yet. Instead, you tried to manipulate them again.
"I think instead, I should fuck your ass." You tried to say it casual, as if thats the most natural thing in the world.

Still, Jennifer looked at you unsure. "Are you sure...I mean..."

"Of course." You tried your best to sound convincing. "Its the most natural thing in the world. Fucking someone in the ass is not as personal or romantic as the pussy. I dont want to get between you and Marcus." You didnt put any influence on the last statement, you just leave it hanging, as you wanted to keep that door open for later.
"Besides", you added, "You promised the winner a price."

"Its just..." Jennifer blushes, "I never had someone..you know..my ass before.."

Just as she was about to look at Marcus, you quickly intervened again. "Thats even better. That makes it less personal, as you wont compare my bigger cock to the feeling of Marcuss smaller one." You took a quick look at Marcus. "Which you would enjoy though."

Marcus didnt answer, but his dick twitched a bit. You smiled. "Either way, I think fucking your ass is an appropriate price. And I´m pretty sure you feel the same way."

You felt exhausted by all the influencing you did, but it seemed to work.
You looked back at Jennifer, which was biting her lip nervously.

"Well...?"
