This happened about 35 years ago ! I was supposed to be picking my brother up to drop him at his work but when I knocked on the door it was answered by his Girl friend Emma. She was in a blue dressing gown tied round her waist ! She made me a cuppa and we went into the living room to drink our drinks ! Emma lay down on the setee and I sat in an arm chair facing her ! I couldn't help but notice her dressing gown had become looser and I could almost see her perky little boobs and her tiny panties ! Without her noticing ! We were talking about the fact that I was a tiny bit late and my brother had already gone ! She then started moaning about him leaving and not satisfying her before she went and the fact that she was still horny as hell ! Me being me I simply said well get your arse into the bedroom and I will sort you out ! She hesitated for all of about 10 seconds and said to me ok but let me go and brush my teeth first ! So I said ok ! She got up and headed for the bathroom closely followed be yours truly ! I wandered up behind her and proceeded to rub my now hardening cock and reached round the front to reach into her robe and play with her gorgeous perky boobs tweaking and rubbing her hardening nipples ! Eliciting some moans and groans ! I then reached into her panties and slipped a finger or two into her hot and now moistened pussy ! It was then time to get her into/onto the bed where her robe was dropped on the floor leaving her in only her tiny panties which hid very little ! The panties soon joined the bathrobe on the bedroom floor ! I lay Emma on the bed on her back and went straight to her gorgeous tight Pussy and started to give her a good licking up and down and around her fine tight little fanny bringing her to climax after climax until she was well ready for me to enter her Cunny with my now solid eight inch cock ! I placed my cock head at the entrance to her fanny and pushed in into her hot little hole until it was right up her twat and nudging her Cervix which seemed to drive her mental bucking and screaming like a wild cat and shouting at me to give it to her meaning my spunk ! I jumped and pumped her for about another ten minutes and then just as she was having a major orgasm I filled her full of my hot Jizz ! We spent the next ten minutes coming down and talking about my brother and what we had just done ! At which point she informed me that my brother had fucked my GF previously which I knew nothing about ! Turns out before he met his girlfriend I had just fucked a good one he had already snagged my girlfriend one friday night in our living room whilst I was in my bed in a drunken state from a large quantity of Scotch ! I also suspect but have no proof but I think my brother was joined in fucking my girlfriend by one of his mates in a threesome ! She became my wife soon after and we have had many adventures in sex since then ! Including many threesomes with friends ! I also suspect if they did fuck her between them that they double penetrated her which we have never done ever ! The End
