I moved into a house couple of years ago and on the first day, met my neighbours. The guy was mid-50s, decent shape, grey hair, bit of stubble. Wife was heavy make up, fancy clothes, snobby. He was very welcoming but she gave me a bit of a glare and hasn't really spoken to me since.
First few weeks, I'd say hello if I saw them. He would chat but she'd blank me for no reason. Whatever. Our shared fence in back garden was damaged in a storm over Winter. She was at my door the day after asking for money to fix it. It was their fence, not even on the boundary, so I said no. She didn't repair the fence, presumably out of spite but I wasn't bothered.
Anyway, at the end of Summer last year, I was chilling in my garden with a beer and spotted the husband doing the same (no fence lol) he asked if I wanted to join him. His wife was out of town for a week visiting her sister. He apologised for her behaviour and after a few glasses of wine he opened up that she had an affair years ago and he wasn't happy but was together for the grown up kids and he couldn't face a divorce. He was joking telling me to not get married because sex stops and then told me they hadn't slept together for nearly 5 years.
He asked about my love life and I told him I was bisexual. I thought he might recoil or get funny with me but he surprised me when he said he thought he might have been bi in his 20s but never experimented.
I joked "it is never too late", not even realising the implication or intending to flirt. He stared at me and then placed his hand on my thigh. I didn't resist. He slid it up further and my cock stiffened. He gently caressed my semi-hard cock through my shorts before I asked if he wanted to go inside...
He shot up and led the way into his open plan kitchen diner. He locked the door and drew the blinds and when he turned around, I dropped to my knees and started undoing his belt. I could feel his cock pressing against his jeans. When I got it undone, I released his cock and he was already rock hard. He was about 5 inches and average thickness. It was a perfect size to take in one go though... I went to town. No foreplay, no teasing. Just shoved his cock down my throat and blew him, fast and hard. It was wet and messy and he moaned loudly and appreciatively like a man who hadn't been touched in years.
As he got into it, he got a little more dominant and grab my head, essentially fucking my face. I was so turned on. After less than 5 minutes, I felt him start to tighten up and knew he was close. I went faster until he shot his big load down my throat. He let out a huge groan. I swallowed.
Immediately after he was hit with post-nut clarity and was all fumbling and awkward. He said he was tired and had too much to drink. I eased his tension by agreeing and said I'd leave.
When I got home, I got my cock out instantly and wanked myself off. I came hard in under 30 seconds over what I had just done.
The next day, I woke up to a text from him saying 'last night was fun. Same again? 🍷'
That night I went round and we drank wine again, both pretending we didn't know why we were there. After a few hours he led me to the living room and this time I blew him for longer. I properly got between his thighs and teased him, giving him a really sensual blowjob. Again he came in my mouth.
Since then, whenever his wife is out, I will sneak over for some fun and help him get his rocks off. We haven't fucked and probably never will but the arrangement suits me.
