Last night, Laura watched us with her mouth hanging open as I plunged “Little Dan” into Liz’s ass. After I pulled out and decorated her back, Laura volunteered for cleanup duty. Again, her pink tongue reminded me of a kitten.
“Laura, I saw how you were watching us,” Liz remarked. “Don’t you ever play with your ass?”
“Yeah, I guess.” Laura sounded ill-at-ease.
“Well, there you go. It’s your ‘backyard playground,’ as simple as that. You might be surprised how much you enjoy being penetrated sometime. I like having Dan up my ass because he’s so long, and back there he doesn’t bump anything tender.”
That was all I remembered of their conversation; I must have fallen asleep. I think I slept well, with some sexy dreams. Along with their plush bed, Laura’s parents must also enjoy keeping their house warm at night. I mention this because I woke up in the morning after a restful sleep without even a top sheet covering my naked body.
The girls were sprawled out asleep on each side, also naked and exposed. Liz was still making her micro-snoring noise, but Laura was dead silent. What woke me was Leanne and Molly looking down on the three of us and making comments.
“Look at that boy’s dick, Leanne, it’s super long! I wonder if I can talk him into fucking us. We’re not that much older than Irene.”
“Ladies,” I replied softly, “I only have sex with these two beauties. NOT my mother.”
“But Irene is so hot and beautiful!” Molly continued. “I’m sure you get hard like that when you two shower together.”
“Molly, no. I love Mom, but not that way! I shower by myself.”
Liz stirred, then. “Dan, wha ... What’s going on?”
“Laura’s moms are trying to seduce me.”
Leanne jumped in. “Hey! Leave me out. This is all Molly.”
Liz objected: “Hey, Molly, lay off my boyfriend. He’s just hard because he hasn’t pissed yet.”
“Liz, can you blame me? I mean, look at that beautiful cock!”
“Molly, I liked you better as a lesbian. He’s mine.”
I still had a “situation” to deal with. “I need to use your bathroom. Liz, come with me to protect my virtue from these rapacious lesbians.”
We complete our usual routine, where Liz peed first. When we left the bathroom after washing our hands, Laura rushed in to replace us.
Since Molly was pouting, I turned to Leanne. “You two had fun with my mom?”
“Oh, yeah. Irene lives up to Yolanda’s description as the tasty...”
I put my hands up to ward off the next word. “Stop, please, I get it. You can see, we had fun as well. I appreciate you being so flexible and letting me spend the night with your precious daughter.”
“Judging by the smile on her face, you did more than ‘spend the night,’ Dan. I can tell she wants you to visit again soon. As long as Liz doesn’t object, I guess.”
“Oh, I’m good at sharing,” commented Liz. “At least, sharing with girls who are our age; sorry, Leanne and Molly.”
I was fretting, a little. “Liz, we should go home. I need to see what’s left of Mom after these two women ravished her.”
Molly interrupted. “Irene was smiling when we left her. I’m sure she wants to see us again. Besides, Dan, as you selfishly deny her sexual satisfaction, it’s necessary for me and Leanne to pick up the slack and attend to her needs.”
“Maybe, Molly, but Bobby and Yolanda were fulfilling her needs,” I pointed out.
“You misunderstand me, Dan. Leanne and I will bring Irene over to Yolanda and Bobby’s house so all five of us can...”
I rolled my eyes and stopped her. “Don’t tell me these things. I’m too young and delicate to know the details of my mother’s sexual life. I just want her to be happy.”
“You’ll find out, Dan. She’s happy. How about you and Liz stay...”
My stomach rumbled loudly, and Leanne giggled.
“Hee-hee. Stay for breakfast, I was going to say. I’m sure you all need fuel after your exertions last night. We have some killer oatmeal we can make with cinnamon and also some fresh fruit.”
All three of us located our clothes and dressed before sitting at the kitchen table. The traditional oatmeal was cooked on the stove (instead of the instant kind), and it was delicious and filling.
Before we left their house, Liz told Laura and her parents that she would find out if they could come over and use their pool and “hang out.”
“I’ll check, but it’s likely you won’t need swimsuits,” Liz added, grinning.
I found Mom still in her bed when I got home.
“Are you OK?” I asked.
“Yeah, just exhausted. Leanne and Molly are each like a lesbian tornado, and I was the old pickup truck flying through the air. Or should I say I was the flying cow? Compared to those two, Yolanda and I have only been playing ‘patty cake.’ You had fun with Liz and Laura?”
“I did, Mom. They assured me that they enjoyed everything, too. This morning Laura’s mothers came home and found us in bed. Molly accused me of incest with you and volunteered herself as another mature partner for me.”
“Leanne probably intervened. She’s the less-crazy one.”
“It seems that way. Do you want to sleep some more or take a shower? I can make you an egg or something.”
“No, sweetie. I’ll find something to eat. I do need a shower; you probably do as well. The two of us are just sexual playthings for all these crazy people. Molly probably suggested you should get in the shower with me.”
“Yeah, no doubt she was imagining me running my soapy hands over your body while poking you with my hard-on.”
“Oh, God! Dan, I love you, but I can’t be in the shower with you.” Angrily, she continued, “Molly needs a spanking!”
I couldn’t help laughing and added, “I’ll hold her down while you wallop her big flat ass, Mom.”
“You don’t approve of Molly’s ass, Dan?”
“Yours is ten times cuter, and Liz’s is fifty times cuter. I might be biased.”
“Ya think?” Mom preened and waggled her butt at me. “We can’t have sex, but it’s nice to be admired, son. I’ll take a quick shower, and then you can have the bathroom while I make myself a little breakfast.”
“I love you,” I had to say it. We hugged, and I went out to the living room, looking for some sports on TV.
Meanwhile, Liz was with her dad and sister. They’d just finished breakfast, and Liz was cleaning up afterwards. Nat wandered off, looking grumpy.
“Thanks, Liz, for cleaning up. Especially since you didn’t eat breakfast here.”
“I don’t mind, Dad. Would you mind staying at the table? I want to talk to you.”
“Sure, what’s on your mind?”
Liz rinsed out the sponge and walked over to her father for a spontaneous hug and kiss.
“I love you so much. You’re the very best dad a girl could have.”
“Well, gee, Liz, I love you too. What brought this on?”
“Dad, do me a favor. Let’s have a man-woman chat instead of a dad-daughter one. Is that alright?”
“Of course. This ought to be good.”
“I hope you think so. I want to talk about sex.”
Barry shifted in his chair, surprise evident on his face.
“Of course you know Dan and I have been banging away at each other for a while now.”
“Just confirm for me that he treats you right and makes sure that you’re, uh, satisfied.”
“He certainly does. So, we went to Laura’s, and, oh, remember, this is two adults having a conversation here. I asked Laura to coach him on giving me oral sex.”
“How did that go?”
“Dad, I almost passed out; he sent me to the moon. Past the moon. When I was able to calm down, I felt tremendous gratitude toward Laura. I realized that my head was in a new place. and I felt the opposite of jealous. I asked Dan, who had been so patient the whole time, to have sex with Laura. He tried to decline for my sake, but I insisted. He exploded inside her and gave her an intense experience too.”
“Elizabeth, slow down so I can understand. I’m happy for the three of you. It sounds like Laura will be enjoying bisexual fun times with both you and Dan. If you’re not jealous, then I’m all for it. But you haven’t explained why we are having this conversation with all these details.”
“I’m getting to it, Dad. While we three were busy together and then sleeping in a puppy pile overnight, Laura’s parents were next door at Dan’s house. Like Laura, Leanne and Molly are best described as lesbian bisexuals. They turned Dan’s mother inside out and upside down. They also discovered that all three of them were having sex with a married couple, Yolanda and Bobby Mitchell. While they are all carrying on, Dan and Laura have both been babysitting Lisa, the Mitchell’s little daughter.”
“Liz, you’re telling me that every woman you know and their relations are having sex. Why?”
“I’m sorry, Dad. Let me get to it. As far as I can tell, you haven’t had sex for YEARS. Why not? Now that I’m having so much great sex, it makes my heart ache to see you so alone. Is it because of my <cough> mother?”
Barry turned his head away and stared at nothing for a while.
“Daddy? I’m sorry, I didn’t mean to hurt you.” Liz started to sniffle. “Please. Can’t you talk to me? I love you so much.”
“I’m going to need more coffee. There’s so much to unpack, and you aren’t wrong. I am lonely. Give me a few minutes to make another pot.”
Unfortunately, Nat walked into the kitchen, got a good look at her father’s upset face, and whirled on her sister.
“What the fuck did you do to Dad, bitch!”
Barry growled, “Natalie, SHUT UP. Liz did nothing wrong.”
“But you’re obviously upset. You’re never emotional like this, even when I really fuck up!”
