Whilst keeping an eye on some friends house,and watering the plants, I stood chatting with the next door neighbour.He was a much older retired chap.I found out he had been in the merchant navy and had been to all sorts of exotic places.He told me that he had many tattoes and offered to show me them. I naturally declined, he seemed disappointed and went back into his house.I continued with my duties, oblivious to the fact he had returned to his garden.I glanced over the fence and he was just wearing a very small of shorts and had a large bulge.He was totally bald quite muscular and very tanned.Now I am a very happily married man, but have always been a bit bi-curious and was a little aroused by what I saw.What do you think he asked,you are in good shape I replied, no he said of the tattoes!I was now embarrassed.Come on over for a beer he asked and you can get dryed off, as in my embarrassment I had spilt water down me. I got over the fence and he gave me a towel & a beer,why don't you take your jeans to dry them he said and without a second thought I did.I was now felling very exposed. We sat on his bench and he moved in very close, we had a lot of fun in the navy, he told me and started to stroke my thigh, I pushed his hand away but he pulled my t shirt to one side, and said your cock disagrees with you! He was right, my cock had started to become erect.He continued to rub my thigh,quite firmly as he had strong hands.He roughly grabbed my cock through my boxers, mmm feels good eh, I nodded.Stand up the said,as I did he pulled my boxers down and my erect cock popped out,t shirt laddy he said and I meekly complied.I was now stood naked in front of a friends neighbour! He cupped my balls and slowly pulled me forward until he could take my erect cock into his mouth, he had done this before!He gently bit around my helmet,and forced my foreskin back and stretched until my helmet was glowing bright purple, he began sucking my cock and rubbing my balls,I was well away in the fresh air being given a blowjob by a man! Unfortunately,my wife doesn't like it, so I was in heaven.I started to feel my cum begin to rise, he too sensed this and took me deeper into his throat, I shot my cum and he swallowed every drop! He licked me clean, wow I said that was fantastic! Glad you enjoyed he replied, now for my turn he said.But I don,t I replied,You fucking do today he shouted.He stood up and pushed me to the floor, as I tried to move away he sat on my chest,gonna struggle are you he said,that will make it more fun he said.He leaned over me and pushed my arms up over my head, this meant his bulge was now in my face.I continued to struggle but he was very strong.He held my hands with one of his huge hands and grabbed my balls with the other,now play nicely or else he said as he squeezed my balls.I was now at his mercy.We stood up and he marched me towards his shed,I felt very scared and very aware I was naked.We went into his shed,where he tied my hands behind my back,forced me onto my knees and linked my tied hands to my ankles.Now you are mine he said.He took of his shorts to expose an 8 inch monster with huge balls.He was obviously very aroused after the fight, he pushed his cock inot my face, I didn't open my mouth at first but he grabbed my hair thrust my head back and forced his cock into my mouth.I started to lick his cock and nibbled it, good boy he said, I felt scared but also aroused,I thought this is OK and began to suck and nibble more and more pleasurable I thought.I gently bit his balls which he enjoyed, now take the whole length he said I want to fuck your throat!!he began thrusting, I thought I would choke,but it felt good.He soon started to moan and I tasted his pre-cum,the moaning increased and he tensed up and shot his cum down my throat! Wow there was loads,I took it all because I couln't move plus it tasted great! A real first for me, a bi virgin.Afterwards, he untied me but only if i agreed to return some time.I haven't been back yet but I am keen to have another bi experience. Don't think my wife would be very pleased though!!!
