Parents swinger friends bring their son sister gets ran through all weekend

My sister and I had a normal childhood until she was we’ll say 14myself 16. That’s until our parents swingers friends staying for the weekend with their son.

Well like I said we had average normal childhood typical brother and sister fight all the time normal childhood. My dad had started working at a new company where he met a guy named Fred and they had us over for dinner. Now him and his wife Ruth were nice people and their son seemed really cool he was like me. Well after dinner told us we could go downstairs and play and that there was ice cream in the freezer so of course their son Billy and me and my sister went down there not knowing how fast our life was going to change. Billy typical boy wanted to show us that he had porn magazines that he stole from his dad and we just thought that was so cool not knowing any better than he started asking simple questions and worked it up to if we’ve ever seen our parents have sex before? Of course not I said we would most definitely get in trouble I thought. Well he starts telling us how his parents have people come over on the weekend sometimes and he will see them walk across the room naked with his parents being with people all the while showing my sister all these naked pics and his boy I start feeling my cock start swelling and during this time Billy is trying to take my sister‘s pants off telling her she’s got to see herself in the mirror naked and how sexy she will be and I don’t know if it was from her naive mind or if she was getting excited but she was naked in front of the mirror while Billy is loving her bald young Pussy. Looking at her I felt disgusting as even only being 16 years old my cock was already larger than most and I am looking at my sister like I had never looked at her before. Billy tells us this has to be our secret saying it’s like we have a club and we didn’t know any better so we went right along with it. With none of the parents at her even coming down or even calling down to see if we are OK and while I am super nervous and I am looking out the door I hear my sister make this painful sound that strangely sounded like a pleasurable moan I turn around and my sister is on the floor with him on top of her and I swear he is fucking her like an adult watching all that porn. And I am just sitting there watching as my sister being fucked deep with a tear in her eye but moaning like she’s wanted it her whole life and I am so turned on with my cock hard as a rock in my hand. As I hear him start making funny noises he pulls out and unloads cum all over her back telling her how amazing her cunt feels. All I knew is all I could think of was burying my thick throbbing cock into my sisters tiny now red and swollen Pussy and before she could even get up I had already pushed her over the couch hard enough that her feet weren’t even touching the ground and I slammed every inch into her fucking ass hard and as fast as possible exploding all over her tiny asshole and swollen Pussy and it was a feeling that will never be matched. Afterwords watch a movie downstairs not even knowing that this would be a common thing for a few years to come as they would come and stay the weekend at our house going back-and-forth we were too young to know any better and I can’t regret that I loved beating my sisters pussy up especially because she would initiate it she always looked forward to when they were coming over which thinking back now is crazy that my sister started her sex life really young with threesomes!! kind of long maybe boring but I dohope you enjoyed it please feel free to let me know what you think and if you have any questions. I am thinking about writing another one about the time that two new girls moved next-door I was 14 the oldest girl 13 even though she was very tiny I cannot remember the name of the disease that is more frequent in Mexicans and I will warn you right now she was an absolute wild one summer vacations were fucking multiple times a day getting as close to the houses as she could oh and I forgot to mention my Uncle ends up marrying her mom so during this time we end up becoming cousins
