I’m 52 and secretly bi my step son turned 18 and is openly gay. I had noticed he was having problems meeting guys and only had limited sexual experience by his own account. His birthday fell on a Saturday so I told him and the wife that he and I were going car shopping. We drove the 20 or so miles to the next town that had the car lots and the Adult toy and video arcade. Over the years I’ve gotten and given many blowjobs here as well as topped and bottomed. He wasn’t really paying attention until I asked him if he could keep a secret. He said yes so I gave him a idea what goes on in there He was nervous but as long as I was close by he wanted to go inside. He asked if I had ever been inside there I told him yes I had He just left it at that We headed in the store. Inside he proudly showed the clerk his Id. Then we bro used the store he liked the cock rings butt plugs and dildos. But what caught my attention was the amount of time he spent in lingerie section. Perhaps he shares my desires to wear sexy clothes. After a few more minutes looking around I asked if he was ready to go in the back And with a smile and a nod we entered the darkness. I directed us to a unoccupied booth. There are no doors but a series of walls to provide privacy. I knew we’d be in there a while so I handed him a 20 and told him to put in the money and select what kind of porn he wanted to watch. First he selected straight porn. I said I thought he’d prefer gay porn. He asked if I’d mind and told him no it’s fine So he started going through the selections and found some very hot femboy porn I could see he was aroused and told him now is when he should drop his pants and pull his cock out so he could start jerking off. To reassure him that it’s ok I dropped my pants and boxers and began stroking my semi erect unit. That seemed to convince him but was still a bit shy. I asked him if I should leave he said no he just was unsure how I’d react to his underwear. Then I saw why He was wearing a lacy white and purple pair of panties more of a thong Im guessing he stole them from his younger sister. I told him he looked great and I wished i would have worn mine and I love how I look and feel wearing them. He then pulled out a very sexy shaved uncut hard. About 6” boycock with matching smooth tight balls. My cock hardened while trying not to be so obvious that I wanted him in my mouth. He began stroking and I followed. It wasn’t very long when a guy in his mid thirties came in and took his very nice 8” cut tool out my son immediately dropped to his knees and began absolutely worshiping this man’s cock and balls the man after several minutes pulled his cock out of my son’s mouth. The man pivoted towards me and inhaled my 7. Between slurps he asked me if I have had any fun with the boy. I said no he’s my stepson it’s his 18th birthday and I’m just here He got up and asked my boy what he was wanting to do. Without hesitation the teen said he was dying to be topped. As he bent over spreading i his ass cheeks. The man moved in to position his cock throbbing I handed him some lube that he had quickly worked into my sons boypussy he turned my boy so he was facing me grabbed his hips and began entering him. I could tell my son had been fucked before but probably only a few times by his ex a very small fem boy I think was only in the 9th grade now they have been off and on for almost 4 years. I kinda think my son dumped him because he was getting to old It seemed to me he has a thing for the slim smooth boys. Anyway it was clear he found a new love of older men and bigger cocks. Then he surprised me by first grabbing my cock and jerking me off then taking me in his mouth and deep throating me expertly I was in bliss. By now several other guys were in our booth jerking off to the show. I was getting close to cumming as was the man plowing my sons ass. When one of the guys jerking off shot his load on my ass checks it set me off filling my boys mouth with my hot seman dribbling from his mouth. I was quickly followed by our new friend planting his seed in my boy. Eventually he pulled out and left his cum dripping from my sons once tight hole. My son said it was his turn and the 4 of us dropped to our knees to be showered by his cum. We got our selves dressed except my son who just carried out his shorts wearing just the thong. He wants to go back asap but first wants to get a sexy corset with garters and fishnets maybe I’ll dress too.
