It was a sunny summer afternoon. My husband, Steve, said he planned to work with our son, Mike, on some things around the house while our daughter, Donna, and I ran some errands.
Our kids were both young adults. Mike had just turned eighteen, graduating from high school. Donna was almost twenty. She recently completed her sophomore year in college.
The house was quiet when we got home. While Donna put away some groceries, I walked down the hall past Mike’s room to stash some things in the bathroom cabinet. His door was slightly ajar. Hearing some noises coming from his room, I pushed the door open a little.
An unexpected sight greeted me. My husband, the father of our kids, had his cock buried in our son's butt. Mike was making little noises of pleasure with each thrust from his father. His eyes were closed and mouth opened a little, while he stroked his erect cock. I guessed this wasn't the first time they'd done this.
Despite stumbling upon the unexpected scene, what primarily caught my attention was Mike’s cock. I had a difficult time taking my eyes from it. It was beautiful. I didn’t care that his father was having gay sex with our son. Bisexuality seems to run in our family. I knew my husband enjoyed having sex with another guy from time to time. I liked sex with another woman upon occasion.
Something else that was part of our family was incest. Once Donna turned eighteen, she gave her virginity to her father, as many other daughters in our family have also done with their fathers for countless generations. I had also taken Donna to bed with me once she had been with her father, teaching her about being with another woman. We made tender love together, as only two women can. After that, we found time to have a girls’ night now and then. Both of us enjoyed it. My daughter appreciated the beauty of what we did in our family. Sometimes she remarked how her first time with each of us was very special to her.
Since these traits were an important part of me, once I saw my son’s erection, I couldn't put it out of my mind. I knew I had to share the bed with him one of these nights. So my husband had to share him with me. I would have done that eventually, in keeping with the family tradition. This made it a priority!
But was Mike gay? He seemed to enjoy himself. I hoped he was like his father, who enjoyed sex with another male sometimes. That was fine with me. Donna and I could be together sometimes, there was no reason Mike and Steve couldn’t do something similar.
We hadn't talked with Mike yet about the things we do in our family. It just never seemed like the right time. I knew it had to be soon because he was old enough to join the rest of us. However, from the looks of things, Steve already had that talk with him. If there ever was a right time to share the tradition with Mike, this would be it.
I heard Mike saying, “Oh my god, keep going!”
Steve said, “Do you enjoy having a hard dick up your ass? Tell me!”
“Yes, sir.”
Steve swatted his son and kept at it.
I turned away, then walked softly back to the kitchen.
“Donna, come here. I think you need to see something.”
“What, Mom?”
“Just come with me. Don't make a sound. You’ll see.”
Donna followed me back outside her brother's room. She looked in the small open space by the door.
Mike’s father was still fucking our son. Mike was enjoying it. Donna gasped softly. The boys were too wrapped in their fun to even notice us.
“Oh my god,” Donna echoed her brother's words. I wasn't sure if the look on her face was lust or shock. It probably was both.
I turned to Donna and whispered, “It looks like your little brother is all grown up now!”
She replied, “Wow, did he ever grow up. I want a piece of that!”
I smiled and quietly told her she’d have to wait in line. “Let them have their fun now. We can all talk later.”
Donna and I continued putting away the things from our shopping trip. Then I got to work cleaning up the kitchen.
I had almost finished when I heard Mike walking down the hall. His father followed shortly afterward.
“Hi, guys. Did you get a lot done today?”
Mike responded, “Yeah, I guess so.”
I laughed. “ ‘I guess so?’ ”
Mike had a puzzled look on his face.
“Mike, we got home a little earlier than we expected. We saw you and your father. It sure looked like you were having fun.”
Mike seemed somewhat embarrassed. His father had a sheepish grin on his face.
“It’s OK, Mike. I know your dad likes to do it with another guy now and then. I don’t mind at all. I guess you’re like your dad in that respect. It’s wonderful that you guys can scratch that itch together. Donna and I feel that way about us as women, too. But I need clarification. You like girls, don’t you?”
“Sure, Mom. It’s like what you said. I find the thought of doing it with a guy sometimes to be a real turn-on just as much as women.”
“That's good because your sister and I were wondering if you would like some time with each of us one of these days.”
Mike’s jaw dropped. “With you, Mom? And Donna?”
Donna said, “Any time you want, bro! You have two women here who would love to jump your bones.”
Mike looked at his Dad, somewhat stunned.
Steve said, “Yes, son, we all have fun together in this family. Your mom doesn't mind if you want to go to bed with your sister or me. I told you that before. She wants to try you out for herself. I say, go for it! But come find me when you want some guy-time again.”
“It's a tradition in this family,” I said. “Your sister went to bed for her first time with your father once she turned eighteen. Now that you're eighteen, you'll be able to join us. Except it looks like you and your dad got a head start.”
Donna said, “We might have to make up a schedule for who gets time with whom on any day!”
Laughingly, I replied, “Maybe we’ll just have a family sex night every week.” I turned to Mike. “So do you want to have some fun with your mom soon?”
Mike had a big grin on his face, but that faded away after a moment. “I don’t think I could do anything now, Mom. I’m kind of spent after being with Dad this afternoon.”
I teased him, “What? Do you have anything left for your sister or me?”
Donna added, “If you’ll be with Mom one of these nights, then I guess I’ll have to take care of my needs with Dad for now. But I’ll be next in line after Mom. I like her idea of a family sex night.”
“I was just joking,” I said, “but maybe that is a good idea. If everyone is agreeable, we’ll give it a shot. I suppose it takes out the spontaneity of things. So if the time is right, and the mood is there, don’t feel you have to stick to a schedule. It’ll just help everyone plan a little better.”
There were no objections.
The next evening, I asked Mike, “Well son, do you still want to try it with your mom?”
“You bet!” came the reply.
“Then come with me.”
As I led him by the hand to the bedroom, I asked him, “So how did you end up in bed with your father?”
“It seems weird to tell you this, Mom. I was horny last week and in one of those moods where I wished I could try it with a guy. Dad walked in on me when I was watching a video on the web of two guys doing it.”
