“Mom…I’m about to cum!” I yelled.
As soon as I said that, my mother’s body became tense and her muscles contracted. Her eyes squeezed shut and I once again felt a steady stream of my mother’s squirting, this time it was through my cock as I fucked her mercilessly.
“Oh god…” she mumbled after opening her eyes. “Cum inside me! Cum inside the hole where you were conceived.”
I was done holding back, I couldn’t anymore. My long time fantasy of fucking my mother was finally fulfilled and I ejaculated inside her body.
When it was over, I collapsed on top of my mother and laid there for a long moment. We felt each other’s chest heaving up and down from our rapid heart rates.
“What a morning,” she said with relief after she had me roll over so she could stand up. “I can’t believe we just did that together. And what’s even more amazing is that I just had the best sexual experience of my life. I’m not sure if it’s because of you or the medication.”
I looked up at her and replied, “Why not both? You probably already knew this, but mother/son incest is actually a really popular thing nowadays. You might have actually loved that aspect subconsciously.”
“No comment,” she said with a grin as she walked away.
I continued resting on the towel where we had sex, and when my mother came back a minute later, she was still wearing only her t-shirt, and her wet vagina and rear end were still completely exposed. She was also holding the small container with the experimental medication inside.
She poured all of the tablets in the palm of her hand and stared at them.
“It’s been an interesting experience with you,” she said playfully to the medication. “Leading me to have sex with my son is where I have to draw the line unfortunately. But I can’t deny that it’s been fun and I surprisingly enjoyed it. Goodbye.”
She reached her arm back and prepared to throw the medication out in the forest.
“Wait!” I yelled, stopping her. “Are you sure you have to throw those out? I mean, your lab has spent a lot of time and money to create those. Plus you don’t have to go back to work for a couple days either.”
She looked at me and smiled, “Well, I guess one or two more wouldn’t hurt. Maybe three…”
Mom put the medication back inside of the bottle and closed it. After she put it down, she pulled her top away, then her bra, standing completely naked with her breasts fully exposed now. There was a surprising confidence in her demeanor. She loved being naked in front of her son.
Even more surprising, she got down on her knees to clean me up. She held me by the hips and took me effortlessly inside of her mouth. Her tongue worked wonders. As she sucked my cock, bringing it back to life, I saw her left hand slip between her legs, and she was playing with her pussy.
I was able to cum again, a much smaller load, and mom lapped the whole thing inside her mouth. Her hands were shaking and so were her legs. She came again.
She sat upright and winked at me. “All clean. Shall we go into the water and wash ourselves? Come on.”
