This bed is too small, and there are four men in the room above them that Alex is semi-fond of. Their kids are in the room--though, knowing ED-E, he's likely in the process of ushering Dogmeat out, if he hasn't already. Most importantly, Neil is recovering from some psychopath's idea of brain surgery, and they still don't know what that will affect going forward. Neil has a fever from the infection, and it's probably not good to raise his temperature higher. Maybe it would burn out the fever, or maybe it would make it worse.

But Neil acquiesces, and Alex, stressed and strained to his limits, cannot stop after that.

He breaks from Neil's lips, to kiss along his jawline and neck. "Tell me no," he says, voice rough and low. "Just tell me no and I'll stop."
