When a man gets a handjob from his clone. It's a decidedly not-gay act (not that there's anythingwrong with that).
Corey was feeling frisky, but had earlier broken both of his hands when he'd sat on them. So, he had his clone give him a Mirror Job, and was still heterosexual afterwards.
When a girl is laying down and doesn't feel like doing the work; so the guy squats over her and does the work of vigorously jacking off his junk in her mouth:no hands bitch; imitating the action of doing squats.
