Totally perverted and disturbed! Sauna visit escalates completely!!!

My girlfriend and I wanted to switch off in the sauna again and when we just came out and sat down to relax I saw how horny the girl actually is, so I fiddled a little with her pussy hihi. When we had both our pussies wet and wanking, this guy suddenly stood in front of us! We were so perplexed and thought we were alone the whole time, but what happened next was really too blatant! Our visit escalated to an extent that I had never expected!
