Connor is a sex bot sent to Hank as a joke / birthday gift by his colleagues, and while Hank doesn't want to fuck an android, Connor gets revved up enough and turned on enough (which is protocol for him with a client) that stopping would just leave Connor unsatisfied and backed up (or the android equivalent of it).

So Hank, not wanting to leave Connor hanging, just eats him out. And he's amazing, and Connor has never experienced anything so pleasurable in his entire life.

And Connor wants more. So he does everything he can to get Hank as a client again.

Bonus if Connor deviates because he's thirsty for Hank, or he realizes he's been deviant for a bit only when he thinks of how much he wants Hank.

Doesn't matter if it's robopuss or robopeen + self lubricating ass, OP will love it either way (: As long as Hank gets to eat out a wet and messy Connor
