"I'm gonna knock you up!"

Fucking this hot middle-aged mom so hard and having her get so submissive triggered something primal and evolutionary in Archie's brain. He rolled with her, ending on top, still deep inside her cunt.

Archie growled into Mrs. Cooper's ear, "I'm gonna knock you up!" Betty's mom gasped and whimpered. Thoughts of her big as a house, pregnant with his child, and fucking him made his cock twitch inside her for a third time. She gasped again, and her pussy squeezed around him, her body betraying her. "I'm going to fuck you every day until you miss your period." Archie started pumping in and out of Mrs. Cooper, making her moan like a whore. His voice and his body were attempting to dominate Mrs. Cooper. "But you'll always use condoms with Mr. Cooper." Mrs. Cooper groaned. The hammer of Archie's dick was hitting a special place deep inside her. "Once you miss your period, then you'll get him drunk and give him every man's fantasy." Archie grunted as he slammed his cock hard into his friend's mom. "No protection, so he thinks it's his, but you and I will know it's mine."

"Unh! Yes!" she cried, "Yours, but he'll think it's his!" Now she was fully possessed by Archie's will. She wrapped her legs around him again, pulling up into him as he thrust down. She thrashed into her third orgasm, wilder and harder than before. The young teen had just come twice, so he did not relent in pounding Betty's mom into the carpet. Hard and fast, her body was pummeled by his rod, and she just kept coming and coming, squeezing his cock, trying to get his cum once more.

"Unh! Unh! Give it to me! Fill me! Pound your seed, your sperm, your baby, into my womb," she whimpered. Then she screamed as her orgasm got stronger as she thought about giving birth to Archie's baby.

Archie slammed her harder because of her dirty talk, and her complete submission to him. It felt better than anything! Images of her on her hands and knees, pregnant belly below her, fat tits swinging under her chest, dribbling milk, getting fucked from behind, filled his head. His climax surged from within his balls so fast, he roared in ecstasy and triumph as his cum shot into Mrs. Cooper's womb, flooding her for a third time with his fertile little swimmers. Her long-sustained orgasm sucked the wriggling mass deep inside her body.

Finally, they both collapsed in post-orgasmic bliss, his cock occasionally spurting another dollop of cum, and her pussy quivering through another aftershock.

After enjoying his conquest for a couple minutes, Archie pulled out of her. She groaned at the loss of his cock.

"Remember, condoms until you're knocked up. This is our little secret. Oh, by the way, I'm fucking Betty tonight too, and you are not going to interfere or I'll tell Mr. Cooper." Betty's mom nodded and moaned. He stood and tossed her the towel that she'd enticed him in at the door. He left the house, thinking about how he was going to get Betty, and how he was going to fuck Mrs. Cooper tomorrow.
