Face Fucking (or face head)

I'm divided between being fairly passive while being sucked, with occasional thrusts, sometimes involutary -- and taking the partner's head in my hands and fucking his/her mouth as if it's a cunt (not ass, I don't do anal). It is a great feeling to have mutuality: she/he thrusts her head, uses tongue and lips greedily; and I increase my thrusting until, after 15 mins or so, I'm ready to shoot, then I hold her/his head pretty firm while I fuck the mouth and throat as hard a I would a cunt fuck. Often they'll gag or choke but I think they like that as much as I do. Most of the cum drools out rather than get swallowed in a head fuck, but it's great when they can swallow it all and look at you in appreciation for what you've done.
