Booking Roberu months in advance and in order to collab with his lower half. Fully able to leave small kisses down his shaft, before slowly going up to kiss the head. Randomly sucking at parts of his cock, swirling your tongue around the head. You scrape your teeth lightly against his head, a choked gasp escaping him, the slight pain feeling good. Roberu questions your actions, wondering if this was really a collab. You assure him that this offcollab woukd bring more than just his numbers up. Before he can protest, you put his entire length into your mouth, your throat swallowing around it. Muffled by the cock in your mouth, you tell him to let loose, to do some fanservice for the viewers. He holds your hair tightly in his fists, thrusting hard into your mouth. “Don’t speak while doing that, stupid!” He says, before beginning to roughly fuck your mouth. He bites his lip and groans everytime you swallow around him, a gasp escaping him as you play with his balls, squeezing them. You hum with him inside, a muffled giggle escaping you, even as Roberu tugs at your hair even rougher. The faster he thrusts, the louder his gasps and groans get. Eventually, his thrusts falter and he lets out a choked gasp as he cum shoots down your throat. You slide your mouth off of him, giving him a quick kiss to allow him to taste his cum. “What a great collab, Robechan! Imagine just how much subs you would’ve gotten if we were live!” You say cheerfully, Roberu falling silent as his face quickly turns into a look of disgust and annoyance.
