Is it normal to get caught by gf's while doing this

Ok, so me and 3 guy friends were all hanging at one of there houses. All of our girlfriends were over and we were all talking and hanging out. Well, they all decided to go get us all food, so naturally we said alright. Well, one of them went and got on the computer, and was looking at porn. We all found out and had a big laugh. He asked if anyone of us had ever done anything with a guy. We all said no, and he said "do you want to?" We all stared and looked at each other but then decided to try it.

We all got naked and started rubbing ourselves, but then one of the others grabbed me and started giving me a handjob, i was a little uncomfortable at first, but it felt great, but before i got off, i told him to stop. Then, another walked over and started giving me a blowjob. We all were doing our own things together, and had lost track of time. Well, our Girlfriends all walked in on us giving each other blowjobs and handjobs and all. We were all embarrassed, but they all laughed and asked if they could join. So they all go t undressed and we ended up all having sex right there on the floor right next to each other.
