Me and my gym partner a true Life story

This is my true-life story …
I'm mature (older) married man and have seen many guys with soft, semi or full hard-on while attending high school, collage, when serving in the army at the gym's locker room, shower area, sauna or steam room.
And, I could honestly say: "Never been (sexually) attracted to guys."
However, all that chanced when Mark (not his real name) being half my age with his good looks and muscular 6'2" lean body of 190lb, 30”waist became my gym partner. (Seeing me struggling doing bench presses, Mark offered to do spotting for me).

On Fridays after gym workout a group of 5 to 8 are going for coffee at local coffee cafe and sometimes at theirs or my place. Mark and I were already gym partners for couple of months when we went to Mark’s new bought condo place for coffee. Due to renovations the gym showers were out of order and Mark decided to take a shower while one of us made coffee. We didn't react as Mark got on the chair with only a towel wrapped around his waist.

Afterwards helping with the clean up and ready to go home to take a shower before doing some errands, Mark offered me to take a shower at his place. As I stepped out of the shower, Mark told me there was still some warm coffee left. I wrapped the towel around me seated myself on the cough. While pouring coffee, Mark’s towel dropped off his body. Having seen him naked at the gym I didn't pay much attention as he now, totally naked, sat down beside me.

Mark's touched my leg with his and out of the corner of my eyes I see Mark's cock getting hard.
I have seen his cock may a times hanging over a pair of large balls but now, I couldn’t help but staring as his dick was swelling and growing until it was fully erect.

Looking up, my eyes met Marks. With our eyes locked into each other, Mark leaned over and as he removed my towel he kissed me. Responding to his kiss I opened my mouth and we had a tong dual. His lips left mine and traveled down and, very lightly, planting kisses on my neck, my nipples down my stomach until his mouth closed around my cock. Mark guided my hand to his pre-cum wet cock. It didn’t take long before I shot my creamy load into Mark's hungry mouth. He straightens up and with his mouth full of cum kissed me and for the first time ever, I had a taste of my own bittersweet cock juice.
While sitting on my chest, I watched Mark jack off and guided his ready to shoot cock towards my mouth. I now had a great view of his cock as white stream cum shot out of his piss hole right into my still filled cum open mouth. It was too much for me to swallow and our combined juices dripped out of my mouth onto my chin and neck.

We became good friends having coffee, luncheons, not to often dinner, serious and light conversations, and cycling and gym workouts. Because of our age difference, we saw it as an uncle-nephew relation. No one expected we were more then friends as we continue our discreet sex encounters at his or my place. We tried many sexual variations; positions and we even trimmed our pubes and shaved hair off our ball sack and ass. Besides Mark’s finger and my doctors,at my yearly physical exam,I didn't want anything into my rectum especially Mark’s thick fat 8" long cock. Therefore I always topped,fucked Mark. But, that also changed after being with Mark for a bit over one year.

While Mark rubbed his finger against my prostate, Mark whispered, “Let's take its step further and let me fuck you okay”? As I was lying on my back, Mark spread lube in and around my rectum making sure I was ready to welcome his dick. With my legs over Mark’s broad shoulders, I gasp for air as his large mushroom cock-head opened my tight virgin manhole.
The pain was unbearable! I screamed “Stop, Ohhhhh, stop” !!
Mark stopped, letting me get used to the intruder inside me. Then, very gentle, he pushed his manhood further and further. Until, I could feel his hairless balls against my ass cheeks.
Pausing then…slowly, just about pulled out …his cock head still inside…. He pushed it all back into me again. The movement was getting faster and faster. Each trust of Marks monstrous cock made me yelling out loud but this time, with pleasure!! “Oh Yeah” … “Ohhhh yeahhhh”.
The feeling was better then I thought it would be. While he was fucking me hard, Mark’s hand stroked my cock and it didn't take long before squirting cum out of my piss hole like never before. The last drop didn’t left my dick when I felt Marks cock twisting and with that, a long. “Agggg” .. Mark shot his load over and over into my bowels....
Staying close together with our legs wrapped around our bodies until Mark's dick slipped out of my cum soaked manhole.

We stayed in touch by emails after Mark moved (work related transfer) to Toronto. Mark got married and two years after his wedding became a daddy.
Our wives met and don’t know we were more then gym buddies and,” THEY WILL, NEVER KNOW”!!

Mark found and having a discreet sex relation, with a guy my age.
Me? ... I’m still looking and maybe one day I’m meeting a new "Nephew”.

PS: Not taken any chances, before I penetrated Mark for the first time and twice after, we both had ourselves checked at neighbouring cities and again before Mark’s departure to Toronto.
In all four times the results was HIV- (negative)!!
