I slid off the stool and laughed as I head up the stairs. I heard June say, “Join us Mom. We’d love to see you in your new bathing suit.” I couldn’t hear what Mom’s response was. I went up the stairs thinking, ‘I wouldn’t mind seeing Mom in that bathing suit again, either.’
By the time I got into my suit and got my erection to subside, the twins were already in the hot tub. I walked past Mom’s room and she was sitting on the edge of the bed looking through the lacey curtains into the backyard. I stopped and stepped into her room. She apparently hadn’t heard me as her attention stayed on the backyard.
Then I noticed that her right hand was up under her skirt and I could hear the squishing noises made by her fingers in her sopping wet pussy. My cock hardened in my suit again as I stood there watching her watch the twins. She had left all kinds of signals indicating her long-term lustful desires for the girls and here she was masturbating to the vision of them in their erotic bathing suits.
Mom groaned hard and her body went rigid. She nearly pitched off the bed into the window. She mumbled, “Oh fuck. Yes,” as her hips pulsed on the edge of the bed. I quietly backed out of her room to the hall. I headed for the stairs, trying to adjust the position of my erection. I knew it was pointless. I wouldn’t be able to hide it. I could wait it out, but I knew that as soon as I saw them in their suits, it would be back and if today was anything like previous days, they’d stare and giggle and I’d be embarrassed like usual. But something seemed different today. The twins were different but I didn’t know why. I was different too. I guessed that that was because of the past two days being introduced to the magic of sex by Mom. ‘Had Mom turned a boy into a man?’ I thought. I pushed the thought away. I didn’t want to be a cliché. I descended the stairs and went directly to the hot tub.
The twins were neck deep in the hot water. The jets were on and directed at the back of their necks. The water rocketed up over their heads and down over their faces. Their eyes were closed as I climbed in and hid my erection under the swirling water.
The rising water level from my arrival signaled a change and they both pulled out of the jets and sat up wiping water from their eyes and spitting water off their lips. Julie pushed herself against me and kissed me on the cheek. She looked to see if she could see my crotch but it was invisible below the swirling water. June stayed where she was.
Julie said, “So, what did you and Mom do while we were gone?” She was examining my face for any tell. I could tell that she was suspicious. My mind flashed back to a few nights ago on the sofa when I had faked my sleepwalking and had mumbled “Mom” to cover my reaction to our sexual encounter. That may be coming back to bite me.
“I mostly hung out here or in the pool or just laid in the sun. I lifted my arms to show the sunburns as proof. Julie squeezed the skin on my bicep and the pinch spots turned white and then slowly returned to red after she released them. She seemed to be satisfied that the sunburn was recent.
