I am currently in the Army , i am single but i have always been bi curious , ive had a little play here and there but nothing to write home about. That all changed over the christmas period last year , i was on a week long security duty . I pulled the short straw and my duty was the far side of the runway , i had a radio , mobile phone , tea and coffee and a few mags to read. My 1st night was challenging but once in the swing i made the most of my time , this including me wanking off ...........as you do. I was visited by the military police for a chat and to tell the truth a bit of company. I was on the dead man early shift when i was visited by Chaz a military sargeant ,he was a good laugh , we chatted and he said im sure you must of had a wank or 2 , guard duty is so boring , i said nothing he said i have a few short movies i will forward to you, we swapped numbers and i waited . He sent 3 movies , normal porn , sucking , anal and sexy undies , i must admit i did knock one out looking at them. The next day he sent me 2 more , 1 was a crossdressing video and the other was a bi sexual one , 2 couples who swapped , the guys fucked and sucked each other it was hot. I got a phone call from Chaz he asked me i wanted a visit when he was doing his rounds , i said yes - i was thinking what do i say , i must admit i was turned on and looking forward to seeing him. It was about 3am when he turned up , i put the kettle on and we chatted , he said did i like the videos i said yes - he said can i confide in you , he said the last 2 movies get my rocks off , he said he was in a open marriage and he had explored his bi side , this is frowned upon in the army but he especially liked wearing undies , i listened and he showed me photos of him dressed in all types of underwear, he did look hot and by his undies bulge he was well packed. Because we were working night shift he said do you want to pop around to my house after work , his wife worked out of town. I said if it wasnt to inconvenient, he left and i said i would pop around about 8. I got there he let me in we chatted and then he went up stairs , he was gone a while , he came in stay up stockings , black panties , and a t shirt , he did look sexy , he said what do you think , i was nervous said its nice , he moved close to me , i put my hand on his waist , his cock was bulging , he said feel my stocking , he said touch my panties and cock , it was so unreal , i rubbed his dick , he was aroused , i pulled the panties to one side and his dick was ready for action , i held it and wanked it , he said wank me harder , he said please suck me , i bent my head , i gagged because of his size , it was warm , he was moving in and out of my mouth , he grunted and i felt a warm release of fluid in my mouth , i spluttered . I was shocked by my actions , i said sorry and i left , i was in shock. That night i didnt hear from Chaz , but my last night he sent me a message , he would be around for a visit , i said OK , we chatted he moved in close and made a grab for my cock , he rubbed me and he said keep a look out , he dropped to his knees and took my dick in his mouth , he went to work on me , deep throating , rubbing my balls , looking up at me as he sucked , he told me to hold his head and fuck his mouth and that was too much for me as i came in his mouth , he sucked and drained my balls , he said that was nice. He said my turn , to my shock i lowered his military camo trousers and he was wearing stockings and suspender , no panties he said it was a suprize for me , i swallowed him and he also made me look up at him as i sucked him off. I didn’t want another mouthfull of cum so i finished him off with a forceful wank , and when he came it was with force . We sorted each other out and he left - last weekend he invited me around to his house his wife was at her sister house , we sucked each other and after begging me i fucked him as he wanked off , i finished off on his stockings. I am enjoying my bi fun and i want him to fuck me too especially if hes dressed up. I wonder if I could wear some of his undies.
