I want to sit on dick, but I’d rather suck it

A skinny girl with tits out is already sucking the guy’s dick with all her might, while rubbing her pussy with her hand. And she wanted to sit on the dick, but for some reason she changed her mind at the last moment and continued sucking. It’s a shame if great sex was ruined due to the lack of a condom, but blowjobs aren’t bad either.
