After Jason's experience having his cock sucked by a guy for the first time, he then regularly come past every Friday after work at my place to have his cock serviced.
He loved seeing his huge cock adored...and enjoys receiving blow job while having a ciggy...
He became comfortable with the idea and eventually, he wanted to experiment with more fun. He commented that I got a nice sexy ass and he asked " can I fuck that?" Without hesitation, I replied "I would love that!" "But you really need to go very gentle , nice and slow coz you got a huge monster cock".
Jason then asked me to turn around. He slapped my ass gently and tried to slide it in between my crack. He asked me "how does that feel?" I answered "damn it feels so good, it feels damn so sexy". I put some lube along the shaft of his cock and let him continue to just slide it on my crack. I felt it was throbbing hard...and then he tried to reach and hold my cock from behind while doing it. This was the first time Jason had touched my cock since all those Friday visits . "Does this feel good?". He was teasing me by pushing the knob of his very hard erect cock on my hole. "Fuck that feels amazing!", I replied. And then very slowly I sensed that Jason was trying to push further in very slowly....then retracting back again..back and forth .It was driving me crazy! Eventually I was almost pleading for Jason to push it all in. He asked me to relax. I initially felt a bit of discomfort as he started slowly pushing in his thick cock . He continued to slowly masturbate my cock..I requested that he put a condom on. I used my mouth to fit the condom on his knob and slowly rolled the rest of it up to the base of his cock. We went back to the same position..
I then felt his cock is now gently sliding in...half of it. I asked him to stop and let me get used to the sensation of feeling my ass wedge ! When I was relaxed enough, he thrust half of the length of his now very hard cock slowly...until the whole length filled me in. I then instructed him to thrust back and forth. "Now we are fucking!" I quietly whispered. I was looking at the mirror at the corner of the room and it was a massive turn on seeing Jason's muscular body fucking me from behind!
It doesnt take long until I felt Jason's body tensed...and he moaned "I'm cummming FUCK!!..I immediately wanked my hard cock wanting to blow at the same time and capture that moment together...He finally thrust the whole length of his cock again deeply when he sensed I was about to blow. We had blown together almost at the split of a second apart. "That was amazing! We both needed that!", Jason whispered to my ears as he got his still hard cock out of my ass, with a visible huge load of creamy cum on the condom.
"Next time its my turn to try and fuck your straight ass" I whispered back. "Well thats not gonna happen, but you'll never know.." he had this naught smile on his face.
