This happened some years ago…
New gf, I’ll call her Kate for privacy’s sake. She was 23, a size 6, 5’3, dyed blonde, blue eyes, and natural D-cups. I was a year older, 6’, reasonably fit martial artist, with a 9” uncut cock. Michael, my neighbour and best friend was younger, a little taller and had a 8” uncut cock.
I shared every sexual encounter with him that I had with Kate since her and I had hooked up. I use to let him peek through the window when we fucked or when she was in the shower.
Anyway, being young and horny, I had asked her to hook us up with some of her friends for a FMF. Naturally she refused, so I offered her a MFM in the hope that she’d agree to a FMF afterwards. She laughed it off thinking I’d never go ahead with it. Little did she know about Michael… I’d asked him if he was interested and as any man that age would, he happily agreed!
