This is a true story which happened about 10yrs ago when I was seeing a girl called Melanie .

Melanie was a runner, she completer 12 Great North Runs in a row and also did a London Marathon before retiring from running due to knee problems.

After each training run Mel would return to her gym for a sports massage from her trainer Rob.  Rob was early thirties at this time, Mel was the same age and I was mid 40s and lucky to be dating a gorgeous, fit blonde girl with great legs, tits and bum. 

I didn't give the massages much thought until Mel started asking me to massage her legs after the odd run. She would complain that I was not as good as Rob and that I needed to be harder and really dig my thumbs into her muscles until it hurt . 

She suggested that I should call into the gym and watch Rob at work sometime. This was arranged with Robs blessing and so I drove over one day to meet Mel after one of her runs.

Mel introduced me to Rob who looked all over the athletic type, had a strong handshake and what looked a toned body under his tee-shirt...no wonder he gave Mel the hard massages she desired with those strong arms .

Mel lay on her front on the massage table wearing high cut shorts ant a tee shirt, her sports bra straps visible as she made herself comfortable as Rob started to massage the backs of her legs and casually chatting to me about what muscles he was working on and how much pressure he was applying. Mel gave out the odd moan as Rob applied pressure to her aching muscles. He moved his hands up her legs and onto the backs of her thighs, again explaining what he was doing to what muscles. As his hands went higher up Mels legs I noticed his fingers were disappearing under Mels shorts...each time going higher and higher as Mels moans got louder.... "I hope you are taking notice babes" she said "cos this is just what I need"..... I nodded and said yes as I felt my cock getting stiff watching this young fit lad give my girl what I wasn't !! 

I looked at the front of Robs shorts and I was sure I could detect a semi erect cock....my stomach tightened with jealousy but my cock was getting stiffer. 

Robs hands were now totally inside Mels shorts massaging her bum cheeks, as Mels moans became louder. I was sure Rob must be pulling my girls pussy lips apart with his actions and I now had a fully blown erection as I felt the atmosphere in the room change from a sports massage to something erotic. 

Rob asked Mel to turn over and lie on her back. She did this with the grace of an athlete but kept her eyes closed, possibly to avoid making eye contact with me. I noticed she was quite flush in the cheeks and guessed this had become more than a massage.

Rob started from Mels feet and again worked his way up her legs...this time in silence. My cock was aching now and I so wanted his fingers to slip inside Mels shorts again.  I was not to be disappointed...Robs fingers then hands disappeared under Mels shorts once again as Mels started to part her legs.  I knew Robs fingers were on her pussy now as her breathing had become shallower and her moans were of sexual pleasure..........then it happened, Mel let out a loud cry as she orgasmed. This brought me to my senses as I realised this must have been happening for quite a while now. 

Rob and Mel composed themselves and Rob spoke first. "Do you think you could do that bubby" he asked....er yes I think so....Mel said she hoped so as it was so intense !! 

Up shot of all this was when we got home we headed straight to bed and I fucked her still wet pussy.  Two weeks later Rob came to the house to give another demonstration this time with Mel naked as I sat in the chair and wanked off. as Rob fingered Mels pussy. I asked Rob if he would like to take things further but declined as he was married
