One of the manliest, hottest things a man can do is know how to fix a car. Then how do you expect a bunch of horny, sweaty, and oily mechanics to resist fucking each other? Especially when it’s the middle of the night and it’s only them and that car they’ve been working on with those leather seats that feel so good on their naked skins. Those cars are not going to fix themselves but those dicks are not gonna suck themselves either.
