I'd be totally cool with a dude jizzing on my hard cock, I'd actually really like that to happen. If I'm hard and horny I'd be cool being spunked on all over my naked body as longs as it'd be below the neck. On my dick would be preferable. I love watching other guys masturbate and cum, so it'd be fun watching and letting them cum all over me while I'm stood there naked with my hands behind back with a hard cock. No sexual activity at all, just being there totally naked, erect, motionless and being wanked on. That would be weird and awesome.
The first clip reminds me of the wife of the guy I became bi with. She loved trying to take both of us in her mouth and would hold them tip to tip and lick under our heads. Another thing she did was suck then rub the tips of our dicks on her hard nipples. It was during one of these suck sessions I experienced my first m2m kiss and loved it!
