Not. Long. Enough.
I like a good long session, at least 20-30 mins at minimum. Rarely happens but it does happen, which is why I enjoy group play so much. One of the guys in my group, about my age, usually drops a load in me after 10 minutes, then dresses and goes outside to smoke a cigarette or walk around the block while another guy takes his place, and when he comes back he goes for about 15 mins in my hole before he plants another one. When I top I go long, it seems the older I get the more stamina I have ('cause at my age, it's one and done for me ejaculationally speaking) so my bottoms get a good thrashing from me before I blow. I'm popular in our group lol - I fucked one young guy for over an hour before I bred his cute little navy ass.
The guy who lasts the longest in me has ED - he pegs me in a sling with a variety of strap-ons until he just fucks the cum right outta me. Longest I lasted was an hour and half but he usually polishes me off in 30-45 minutes.
