Dirty Old Man

My wife and I don't have sex much anymore. Both of us are in our 30's and the lavk of sex bothers me. She would rather go to the casino and bingo hall with her best girlfriend during the weeknights. She likes playing the slots especially. We are both overweight with her being noticeably full figured. I stay in some kind of shape by swimming at the Y M C A in the mornings before work.

On weekends we relax watch movies and do dinner out. Being at loose ends during the week I began hanging out with our older neighbor in the condo across the hall from us. He invites me over and we have great chats, play cards,listen to music etc. My neighbor Mark is a retired silver haired late 60's senior very well read and tall with glasses. I ended up over there pretty much every evening once my wife left. A few weeks ago he must've forgot I was coming over at the usual time around 7. His door was unlocked and I walked in. Mark was on his couch jerking his cock to some gay porn on his TV. I stood there stunned and he did not notice me at first being lost in masturbating. His cock was rock hard around 6 inches cut with a black cock ring at the base. Finally he saw me and stopped. " I am so sorry I don't blame you if you walk out right now. I am such a dirty old man." he blurted out. I was still trying to process everything and had not moved. He looked at me more intently." Come sit down then" he said quietly. Almost like being in a trance I sat down beside him. Mark reached over and unzipped my pants and lifted up my t shirt. He felt for my cock which was now stiff like his.I moaned as he caressed it with his right hand as he fondled it with his left." Let your dirty old man pleasure you" he said seductively. He then stopped touching himself and leaned over kissing me as he jerked my cock. The kiss aroused me even more as I felt my cock starting to spurt. He milked me over my big tummy. He finished me off. I sat there feeling huge sexual relief. A short while later I reached for his cock and masturbated him. Making him cum excited me. We kissed slowly after in that post orgasmic glow. We watched more gay porn then he bent down and sucked my cock until I filled his mouth.

That is how it started with Mark. He became my dirty old man. I go over we watch gay porn now in his bedroom make out and have sex. Sometimes mutual oral and masturbation but more often slow intercourse as I take Mark's cock in my big ass usually with him on top of me but sometimes from behind. I crave my old man's cock in my ass and it stopped hurting months ago.
