Caleb's keeping an eye on the rest of the Nein during a mission with Frumpkin. While he's doing this, someone else comes across him, and realizes that he can't hear or see what's going on even if he can feel is and respond. So, they take advantage of the situation, moving his body how they want it and then fucking him senseless. Caleb just lets it happen, because he needs to make sure the rest of the group isn't in danger, and he can't really do anything about it without either coming back to himself or getting Frumpkin close enough that he'd have no line of sight on the others. So they use him to get off and then just leave him there, absolutely filthy and used.

+the Nein move a little at some point, so Frumpkin comes closer to where Caleb is to follow them, and Caleb can hear everything, including lots of dirty talk and slut-shaming, and his own noises
+more than one person ends up fucking him
+it's in a public or semi-public space, like an alley, and maybe it's the middle of the night but anyone could still come through and see
(++...someone does see what's going on... and then they join in on the fun)
+creampie, breeding kink, come inflation, etc.
+objectification, degradation

-bathroom kinks, vomit, painful sex
