He knows he should protest, he should pretend to be horrified, but there's not much energy left in him for acting like he doesn't want it, like he's fighting against Chris' wishes. The other's hands on him only make it more apparent how much he likes it, now that he's not being held and forced into positions he can move freely, pressing back against each of Chris' fast, eager thrusts and groaning with each. Why pretend that he's not meant for this? Just like Chris says, taking a cock, over and over, being pounded, it's what he wants.

And for a moment, his head tipped low, his mind is blank to everything other than pleasure and Chris' words. But not long, because there's something different, something changing with each movement of Chris' cock into him. It feels almost like he's being stretched further and further, opened up more and more as Chris buries himself into Jacob's heat.

"Oh fuck," He groans, remembering now what Chris had discussed before, the fun little additions he can make to this, the various potions, lotions and spells at his disposal. Including this, which makes his eyes roll back in his head as his body willingly accommodates the swelling cock, and he reaches back to try and get Chris to slow down.

"Just- just stop, a minute. In me. Wanna feel it-" I want to feel it grow, he doesn't have the words, but it's incredible, wonderful, perverse. And he can't get enough.
