*****
I would say my childhood was fairly normal. Having just turned 18 last week, I was the youngest of 3 kids. I have an older brother, Tommy, who is 22. He's 5'11 with dark brown hair and deep blue eyes. He's fairly muscular, and works as a mechanic. He lives in a small apartment above the garage having an agreement with Dad that he could live there for free if he'd fix dad's car free of charge whenever something went wrong, and something was always going wrong.
I also have a beautiful 20 year old sister, Samantha. She has soft pale skin and bright red hair, just like my mother. She is little and petite, but has a nice, round bubble butt that I've always paid extra attention to when I'd see her in a bikini around the pool.
Mom and Dad are also extremely attractive. They're been together for 25 years. Dad, Joe, is 45, he's extremely muscular from his job in construction, with his chest and abs covered in thick black hair that matches the hair on his head. He is 6'2 and has always been the head of the house, in a very dominate but loving way. Mom, Lisa, on the other hand is very sweet and docile. She isn't as fit as she was when she and dad first married, 3 kids will do that to you, but she's still a knock out. At age 44, she has long beautiful red hair that has yet to show gray, she had large breasts and a shapely ass which you could often catch her shaking back and forth while she vacuumed.
Then there's me, Jared. Newly 18 and a couple weeks out of high school, I was enjoying my last real summer of freedom before starting at the local community college in the fall. I'm fairly average in most respects. I have dark brown hair and blue, eyes. I'm 6 feet tall. I'm not super muscular like my dad or brother, but I'm in decent shape. I have a nice layer of hair on my chest and just above my cock, which is the part of me that's far from average. At 8 and a half inches long and 5 inches thick it's always been my pride and joy. I always got off on showing it off when I had the chance.
I've always known I was bisexual. If someone was attractive I knew it and whether they had a cock or pussy didn't really change it, which made growing up in my family so difficult. Constantly surrounded by 4 sexy people of different genders can make a teen bisexual explode, and I did almost every night in my room thinking about some combination of my family and me fucking, thinking it was only a fantasy, my family isn't like that. How wrong was I.
While mom seemed thrilled to have all 3 kids staying under her roof past the age of 18, dad seem slightly annoyed. At first we thought maybe we were just being paranoid, that he truly loved us and wanted us around, but one night at dinner my brother finally spoke up and we learned that we were right, but not for reasons we might have thought.
"Dad, there's something that's been on our minds that I want to ask." Tommy stated.
"Well what is it" Dad replied.
"It's just since Jared and Sam are staying here during college and I live above the garage, you seem like your slightly annoyed at our presence."
"To be honest, I am." Dad said.
"JOSEPH!" Mom snapped.
Sam, always having to be right, "I told you so."
"Now everyone let's not get this whipped out of proportion. I am slightly annoyed that you're still here, but not because I don't love you, but because I really love your mother. We've always been a family to talk openly so here it goes. Before your mom got pregnant with Tom, we use to be real nudist like. We'd walk around naked all day, not a care in the world. If I got horny, there was nothing stopping me from taking your mother anywhere any time I pleased. I raised my kids and have waited 22 long years for that kind of freedom again, and by god, I just wanna be able to come home strip nude after a hard days work and fuck my gorgeous wife anytime anywhere that I want."
We all sat silently for a minute, not sure what to say. It's true. Mom and Dad's sex life over the last two decades has been relegated to waiting until all 3 of us were out of the house or doing it in absolute silence at night. As my room was next to theirs I'd sometime hear the subtle creaking of their mattress, and would get horny knowing that dad was probably balls deep in my mother.
I was the first to finally speak, "Well, you shouldn't let us stop you."
Everyone suddenly looked at my with a slight confusion.
"Pardon?" mother softly said.
