Curiosity Got My Hole

Being in a sexless marriage for nearly two years (we've been together since being teenagers) one of my neighbours comments pricked my curiosity.
Chris my neighbour, who's just turned seventy, told me he and his wife hadn't had sex in years. But that hadn't stopped him from having sex.
When I jokingly asked him who he was fucking, I wasn't expecting him to say, guys he met off a gay hook up site.
He'd told me all this because he found me sat on my rear patio looking glum. His words to me were "You not getting any". Which lead to his comments.
I must have given him some kind of quizzical look, because his next statement before he headed back inside his own home was "They like my nine inch cock".
My first reaction was yeh right. And I kind of left it at that. However a few weeks later, I saw him dropping off a younger guy outside of the shops I was at. The young guy leaned right over and they kissed like lovers before he got out of Chris's car.
And it turned me on like never before.
Later at home I saw him in his back garden and couldn't help myself. I asked him if he'd fucked the young guy I'd seen him with. Chris smiled and said they'd just ended a year long affair, as the young guy was moving.
Still smiling my neighbour said "Why, you wanna take his place".
It had never occurred to me I'd ever want to have sex with a man, but I couldn't deny his comment had my curiosity going again. And my cock aching for sex.
There was no deep thought to what I said to Chris, I just reacted to how I felt when I said "Where".
If you'd have said to me within half an hour of a much older man inviting me into his home, I'd be on my hands and knees on his couch, taking nine inches up my arsehole, id have laughed at you.
But that's precisely where I found myself. Chris had told me we didn't have long before his daughter brought her mum home. So you could say I had a crash course in gay sex.
As soon as we got into his lounge he took off his trousers and boxers, sat on his sofa and told me to suck it.
It was the first guys cock I'd seen up close, let alone having to suck it. And I was totally new to male male sex. Yet that didn't matter to Chris as he pushed my head down to his growing cock.
His dick really is nine inches and makes mine look small in comparison. But Chris did let me take my time somewhat in getting used to having a guys cock in my mouth.
I wasn't I'll admit, very good at giving head. Not that first time anyway. But time that day was of the essence, and to be honest by the time his cock was practically flooding my mouth with pre cum, I had a bizarre need to discover what all the fuss was about being fucked.
Kneeling up on his sofa after Chris had me strip naked, he spent about ten minutes licking and tonguing my arsehole. Id had it done to me in the past, by a girlfriend who loved anything anal, but my wife had never tongued my hole.
Chris is so good at it, I found myself begging him to fuck me. It's still a thing between us that he had his full length up my arse within half an hour.
He calls it his bedside manner. I'll call it, him having a beautiful cock.
When he first entered me, I didn't think my arsehole could take his size. I wasn't behind the door, id seen gay porn and knew men could take large cocks and items up their fuck hole. But it was my first time and I was a little scared.
A natural is what I guess you'd call me and my arsehole. Yes there was some pain and resistance. Butt, pun intended, my arse enveloped his cock and Chris wasted no time in fucking me as hard as he wanted to.
The seventy year old would put younger men to shame with his sex drive, and how rough he loves to fuck. He pounded me for a good fifteen to twenty minutes, stopping only once to have me lay on my back before entering me again.
Leaning right over me, thrusting hard into my arse, my neighbour pulled my face to his and we began kissing.
I loved it. I can't tell you how much I'd missed that intimate act of kissing and we didn't stop kissing until my cock had erupted between us, and Chris had cum deep within my bowels.
Still kissing after we'd both orgasmed, his phone bleeped. Lifting off me, he said we had about fifteen minutes before his wife got home. It gave him ten minutes to have me suck on his cock and taste his cum and my anal juices. Again I loved the sexual intimacy of giving him pleasure that way, and its now something I always do for Chris.
When his wife walked in, she smiled at me, gave him a knowing look and asked if i wanted a cup of tea.
It was a little surreal drinking tea with his wife there, and I got the distinct impression she knew her husband had just fucked me.
It's been easy for Chris and I to have sex over the last nine months. We have oral sex most days, and when my wife's at work and Claire his wife is out, or these past few months 'having a snooze' he fucks me so wonderfully.
I now know Claire knows her husband is fucking me. She's totally indifferent to us having sex, but I still feel weird knowing she's in their house, as her husband is balls deep up my arsehole.
As for my wife, I'm not going to hide anything if she discovers our neighbour is fucking me. After all, I now believe she's having fun with her female hairdresser.
