Son: "Wow, a landing strip. I thought you didn't care about shaving down there." She stuck her legs out and wrapped it around his waist to pull him close.
Mom: "I need this and I need it now."
He pressed his member unto her pussy lips, readying to thrust. Completely unknowing that this was his own mother and that this was her dangerous day. Her pussy was dripping with anticipation, welcoming her son back home. With one thrust he slammed into the womb, causing her to squeal with pleasure. Pulled and could feel the vaginal was suck on him, refusing to let go. He thrust again, and again, and again. He'd never felt his girlfriend's pussy feel this good before, but he couldn't think about that. All he could do was focus on breeding her, following instinct to press deeper and harder into his woman. He kept pushing harder than ever before, this was nothing like the pillow princess his girlfriend usually acted like. This was primal fucking. He couldn't hold it any longer, "I'm gonna cum!"
"Inside, cum inside!" she demanded. He couldn't keep his thoughts straight, he plunged deep into her pressing up against her womb entrance and came directly into her womb. This cause her to erupt with pleasure, a sexual act so wrong, but so right. She came that hardest in her entire life. Her body floating feeling nothing but the burning hot cum in her belly and the strong embrace of the man that took her and made her his.
"I love you." She whispered before taking off her mask and kissing her own flesh and blood. Shocked, her son didn't have time to react. His member still pulsating within her freshly creampied pussy, he stopped thinking and forced his tongue into his mother's mouth. The heat of her breath, the strength of her tongue now wrestling his. Her hands running through his hair, he chose simply to ride the wave of hedonistic pleasure. This was no longer his mother, this was his woman. And he would please her. He pulled back his member, she gasped for air finally letting go of her son's lips. He slammed back into her so hard she fell back into the futon it broke the couch backing. But neither of them cared. The heat of pure sex radiated into each other and they were now in a world where only the two of them existed. Over and over he plowed into her, pulling out and pushing in were the only things that was on his brain. He felt her tighten, she was near.
"Kiss me." She begged. With his last thrust he locked lips with her, releasing the last of his cum into her. Kissing the woman he claimed.
In the post coitus they revel in the heat of each other's embrace, both content knowing that this will be far from the last time they ever do this. As they kiss again they hear a knock at the door.
"Uh dude, not to interrupt but..." as the door opened she scrambled to grab her mask so no one would know. "I heard some wood breaking, did you break my futon?"
Son: "Oh yeah, my bad. Uh why don't I take care of this why you head home mom?" Everyone heard him say mom, one said "Woah dude, I didn't know you were into that kinda play."
She was glad to be wearing a mask, as her face was now red as a cherry. She tried to walk past to leave, but her son couldn't help himself and gave her ass one last squeeze as she made her escape. His own little way of saying expect more when I get home.
