girls had a threesome with my dad on my 18th

My Favorite Sex Story:
Well it started off when i first hit 18, my Girlfriend of 7 months just broke my heart and thought it was appropriate to come to my 18'th. So as any man would i over reacted and instead of being myself was just trying to be with any other girl just to make her jealous and by god i did, i remember talking to 2 friends of my best mates and they must of known what i had in mind being its my 18'th. we got talking and me and the 2 girls got to my room and made out for a while, then half way through all the cloths coming off, my x walked in then ran off. i whipd my pants back on and ran after her. i caught upto her car and stopped her and we talked for awhile which turned into us making love in her back seat and becoming a couple again.
the next morning we went back to my party (which i shouldnt have left) and i walkd into my room see'ing the 2 girls i was with then see'ing my dad pop out from under the rugs saying " happy 18'th mate".

was something i will always remember
