Interesting subject. I have experienced these several times.
I go soft whilst a real man is hammering away at my cunt. I try not to wank for a week or so before a session. The interesting thing from my perspective is that I can have 2 different ways of emptying my faggot balls whilst being fucked.
The first is prostrate stimulation from a lovely daddy dick. Secondly i really seem to react to having just inside my cunt worked over. A cock or dildo that slams in then pulls all the way out really gets to me. I’ll dribble and squirt my cum hard with both, I also empty my pig bladder in time to the thrusts as a completely lose control of my faggot functions.
The orgasms are very different to the feeling of a normal cock stimulated orgasm. If I come 3 times anally I still want to come using my cock at the end of the session.
In the UK, if you want to test drive my hole I use the same name on BBRTS and Squirt. I’m Pigboy73 on Romeo.
