My Ideal Person:
So you have to work harder to lift my big balls with one hand so they don't bang around as you jack me hard and fast with the other. Sucking on the head also helps a lot to milk that pre-cum out that needs to be drained for dad to feel ok until you can come back the next time. If you should try to make dad have an orgasm at the end though, you might cause him to release a little piss when he shakes and climbs the wall moaning.
