I’m pretty sure this happened to me when I was about 17?
My then girlfriend (short time) Linda also 17, had a house party! I had a mate having a party on the same night nearby! My mate and I flipped between the two houses all night!
Upon my return to my girlfriend’s house much later, she grabbed me and dragged me into her bedroom! We were fucking within seconds and she was very ready! A few minutes later a bang at the door and Linda’s mate said; ‘blimey Linda, who have you got in there now!’
I carried on as I was enjoying myself and never questioned her about it!
We didn’t last long, but I still often wonder?🤔
