Yes. I'm involved with several people in my life, and enjoy threesomes regularly. It involves a lot of trust, and you have to really know your friends well or else someone is going to get very hurt. From experience...
ETA: I have been in both MFM and FMF threesomes, and they are fantastic and fun with the right friends. One of the first ones I had, though, was an MMF - as someone pointed out earlier, it is where some male-male contact happens on purpose. I went into it thinking my friends were going to concentrate on me, because thats what we talked about: I wanted to experience two guys at once, and these friends from school were more than willing .. I'd had sex with each of them separately a few times. Well, we were into it for a little while, and I was loving the intense feelings of 2 penises and four hands and two mouths all working on me -- all of a sudden the action stopped, and I saw the guys "doing" each other....I was disappointed and a little upset, felt abandoned and a little betrayed. (And yes, that is exactly what you don't want to happen in a threesome - it can wreck a very nice friend group). S
So now, I've chosen guy friends to play with that have no interest in being inside of anyone but me while we're together. As for the FMF, thats different - it always seems to be FFM (with the Fs changing places) then, when M has to take a break, it becomes FF, which is awesome .... and most guys I know love watching the FF because it usually involves cum play and snoballing and other fun things ...
Definitely, good to the last drop! And, after he deflates a bit, taking him back by my face to very slowly lick those last drops off -- part of the game!
Female cum quite tasty, too. Not a great deal of experience with it though - mine, of course, and a couple of close girl friends. Most of the time, it seems like just licking something that keeps getting wetter and wetter. One friend has a mini-squirt -- that is fun.
This morning, in bed .... or, maybe you want to know that I took it in my mouth?
ahhh, cum! Wonderful stuff! My default action is to swallow - A few other posters have mentioned that swallowing is the best way to avoid messes, and that's pretty much the reason I first started swallowing, waaaaay back in high school (or was it middle school?) Didn't have my own place then, and didn't want to leave puddles and stains on a rug or couch - or even worse, my mom or dad's car seats or windshields. It didn't take long, though, to actually enjoy it - I went from "OK, I'll blow you" and catching the shot in my mouth and just gulping it down to finish things, to asking "Can I give you a blowjob, and will you cum in my mouth?" --- I started really liking the whole act, from anticipating it to signalling that I wanted to do it to actually playing with my friend's penis to feeling the warm cum on my tongue and loving the taste, texture and look of "omg, thank you" in my friend's eyes as I swallowed.
Of course, if he wants to shoot it somewhere else - boob, butt, belly, into outer space -- no problem - I can clean him up with my tongue. I don't like cum on my face as in a facial, though. Never have. Don't really know why.
