he used another guys cum as lube

i hooked up with one of my friends yesterday and he ended up cumming inside my ass, and he plugged my ass with a buttplug

what he didnt know was after that i went to another hookup i arranged, and when we fucked he saw fhe buttplug and asked if he could fuck my ass and i naturally said yes. when he removed the buttplug my friends cum was still there, and when he fucked my ass i felt him go rougher. he ended up cumming jn my ass as well, and i could feel it overflowing in there
