Ex girlfriends 18 year old sister

[irishpablo]

About 15 years ago the girl I was with at the time left for work and as always left me sleeping in her bed in her mums house but her little sister who's room was next to hers I cant remember how it happened but her bedroom window was broke so when my girlfriend got up for work she told her sister to get in bed beside me but my girlfriend forgot when me and her woke up whoever woke up first usually went down on the other so couple of hours later I woke up and done the usual, up against her ass kissing her ear and then hand down her knickers and get her wet but this time when my hand went down her knickers completely shaved and my gf liked hair, she kept it tidy but she hated a shaved pussy. I noticed it was shaved but I still didn't click on but she did and she turned roun and went down and sucked my dick. Deep throat from start to finish and i came in her mouth, both again that my gf didn't like. Except if she was drunk .
Anyway I finally pulled the blankets back and said to her sister what r u doing and she said "I've been listening to you fuck my sister for 7 years so your gona fuck me for the next 7 hours" and i did and it was the best sex I've ever had. That good I fucked her for the next 5 years. Got her pregnant, married her and had 3 more kids and we still joke about to her sister which was my ex for telling her to get into bed that morning with me.
All still good friends btw. Madness!
