I think my fantasies have changed as I haven't older. When I was 18 I wanted to fuck an older woman so at 18 I was shagging a 31 year old married bird. Then I discovered her husband played second row for on the the hardest sides in Cardiff. We were in the same league and, luckily, had played them home and away that season.
Fucked a woman I was working with on a regular basis and then on a night out picked up this bird, took her to the local beach and fucked the living daylights out of her. Then, one day in work I was talking to my girl in the office and in walked the girl I had banged on the beach. It turned out to be her sister in law.
Others include banging my (then) wife over my desk and also banging my receptionist over my desk - on separate occasions you understand. The same receptionist was a very game gal and would regularly blow me while we were doing along.
On the prossie front I have done a few MFF threesomes most OK but not all they're cracked up to be. Had a regular prossie who I used for outcalls who would turn up naked apart from stockings and suspenders under her coat and would get straight on her knees to suck my cock as soon as she was through the door or spread herself on the sofa and tell me to lick her cunt and make her cum before fucking her arse.
Nowadays I like a plain and simple, no messing about, really dirty fuck with no holes barred, lots of dirty talk and reward her with a mouthful or face full of spunk.
