Returning the favor with a blowjob

"Aw, thank you, you're both very cute. But you" you point to the one who just came, "Need to apologize to me for refusing your princess's order, and thank your brother for giving you pleasure."

He blushed. "I'm sorry for not obeying you, Princess. And thanks, Frederic, for making me cum."

"Very good. But actions speak louder than words, and if you want me to forgive you, you have to repay me with your actions."

"I... you're right, what do you want me to do, Princess?"

⚀⚅ - 1 (Charisma) + 1 (Incest Fetish) + 2 (Submissive towards you) + 2 (Circumstance) = 11

"I will forgive you... if you pleasure your brother with your mouth."

He goes bright red, but looks at his brother, still clothed, and nods, "Frederic, please strip so I can... so I can give you a blowjob for the princess."

Frederic obliges, and soon, the brothers are both naked, and you can only tell them apart because one has his hands still tied behind his back. You see his hands again as he bends over to his side, lowering his head until his mouth is close enough to his brother's cock for him to give it a tentative lick. He doesn't seem to object to the taste, as then he opens his mouth and accepts the rod into it. Without being able to use his hands, he has to rely on his stomach muscles to move, and it's clear that he can only slowly bob up and down.

You want to get a better look, so you leave your chair and sit on the floor, watching from close range as the man slid his mouth over the dick in front of him. The cock is shiny with spit. "Do you like the way Frederic tastes?" you ask with a smirk.

"MMMMmmmmph!" he tried to respond, but it just came out as just a hum, and the vibrations caused Frederic to moan.

"I think he said yes." you tell Frederic.

"Princess... He's going too... too slow, I won't be able to cum."

"Oh, I see."
