Nineteen at home, a friend of my fathers shows up with his latest girlfriend who's even younger than I am.
My dad and his friend head off to the pub for a couple of hours, leaving us behind.
I tell her its my birthday , she asked if I had a girlfriend which I didn't at the time.
Then she said "No birthday sex for you then......unless you'd like to fuck me"
Half an hour later she climbs out of my bed and makes a call and after a short wait two of her girlfriends show up....un fucking believable....my first foursome
Found out a few years later than the whole thing had been a set up thou the girl really was dating my dads friend at the time. What spiced it up for me at the time was the fear of getting caught.
