A party that ended in a dirty sex orgy! Part 2

I was invited to a normal party at my girlfriend's house in the evening. We were 4 girls (2 girls and 2 milfs) and 4 men! After a while, the party degenerated into a hot sex orgy. Everyone fucked everyone and that back and forth. There was fucking, blowjob and licking! So it was more or less behind the scenes, without agreements and for hours!!!
