I've had similiar cumming like this bottom. Didn't know if I was going to piss and cum or cum and piss. On rare occassions I've shot a big clear load of precum followed by an uncontrolled piss. Thats when you know you've had a good top in you.
The Sounds of guts and organs being poked, shifted and interfered with. If you thrust into my body like that, I am quickly leaking cum down onto that camara filming me, my rectum convuslsing and spasming in protest as you fuck the cum out of me.
If anyone is trying to figure out how to make a bottom cum hands free, it's basically this. High stamina + really hard ball-slapping pounding. The harder you thrust the more the prostate wears itself out, letting the bottom release.
