I mostly bottom, but was very horny after getting 2 loads, one from an undetectable poz guy, then a guy in an hostel for men. He was dirty and smelly and fucked me in his room bent over his bed while his room mate sat watching a mini tv with head phones on. Didnt ask his status so no idea. i was still horny, but could not find another top. A bottom hit me up on BBrt and said he was collecting neg and std free loads only. Last time i tested i was neg and std free so i said sure. He was waiting on all fours on his bed after leaving his apartment door open. He was totally not my type and i could not get hard.i fingered his hole and played with myself in an effort to get hard. He said you are neg and clean right, Yes. Spat on his hole and fingered him some more, Rubbed my flaccid dick on on his hole and he reached back and pulled his cheeks apart. Nothing! Then i had an idea, i cupped my hand under my hole and squeezed out a big dollop of the two loads i had taken. i dropped in his crack just above his hole and i got hard in seconds as it ran down and onto his hole. i pushed the cum in with my dick and started fucking him hard. i squeezed some more out, dropped it on his hole and fucking it in. Didnt take long to blow my load. So he ended up with 3 sets of DNA in him mine, the poz tops and the homeless guys. i think that was a good reason to push out my injected cum.
