It's difficult to make me cum. So, I usually make the bottom cum first, unless they stop me because they want to hold off. Some are determined to make me cum, and from time to time I've had to tell them I know they need to release, and It's OK--take care of your own needs. (Funny, over the holiday weekend I bumped into a pornstar friend, who remembered and mentioned just such an encounter with me from something like 15 or so years ago.) Some stop me just before they cum, because they want to save it for a fresh round later, or because it's a sex party and they want to service more tops (and they'll probably get me again, too). I really like making bottoms cum, and feeling their release from the inside. I've enjoyed some wonderful multiple-cummers! In a 1-on-1 situation, most will help me get my release afterward, usually by playing with my nips while I stroke my load out for them.
