I slammed in a local sauna, just 0.2 but I was flying high, walked into the dry steam room (I didn't know it WAS actually dangerous to do when your heart rate increased like hell). Anyway, I got myself naked at sit somewhere in between with other 5 guys, approaching happened not long after. In a few minutes, I got banged by 4 tops, all sweaty and horny, all bareback, some even cum inside me.
Another occasion when I visited a foreign sauna, did slamming too, after that 3 guys invited me for a 4 some. We split into 2 pairs at first, no one said about practice safe sex so bb was by default, I was so high and I could feel every thrust, it was damn sensitive. Then we switch partners, that was one of the best and wild 4some ever.
