sfuck

(v.) Usually limited to homosexual male intercourse, to sfuck is to fuck a man in the ass while simultaneously sucking his cock. This isn't possible in all positions, nor in any positions for people with major back problems. Note: a woman wielding a strap-on could achieve the same position, and it would, technically, be considered straight sex.

I sfucked a guy last night, and he came in my mouth right when I came in his ass.
