Jeff's sister kept muttering how perverted Jeff was, as she left her room. Thankfully, their mother was nearby to eavesdrop her daughter's words. Sneaking in, she immediately grabbed the keys to the cage on the dresser; then proceeding to free her son. "Are you ok, Jeff?"she asked her dick son, who was throbbing thanks to being held by the soft, warm hands of his mother. She too noticed his light twitches as his length expanded from the blood flow. As he grew to a length even she found admirable, Jeff's mother heard the sound of her daughter closing a door downstairs. "She's coming back up!" She worried, leaving the bedroom. But, where could she hide Jeff; his sister would surely search the house to trap him again. "There's only one available place." She thought, looking down. Slipping down her shorts and panties, she slowly shoved Jeff into her moist pussy. "Nnghk!" She moaned as her son filled up her vagina completely. "There. It's safe back inside me." She said, pulling her clothes back on.
Jeff, however, was shocked that his mother had just stolen his virginity. "No way." H thought, as he was able to control himself enough to start thrusting back and forth. His mother obviously felt this and looked down "Jeff, sweety, there's no need for that." She moaned, as his thrusts got faster and faster, pressing the tip of his head right against his mother's cervix. "Wait...." She pleaded, as he came right inside her womb. "That was awesome." Jeff moaned, still throbbing. "I'm doing this all the time from now on." He decided. Going for one big thrust, he extended his length enough so that the tip of his dick slipped into his mother's cervix, with the opening tightly locking him in. "AAAhh!" She moaned, instantly regretting this and pulling her clothes off again. Grabbing Jeff's balls, she wanted to pull her son out; but, thanks to him penetrating her cervix, he was stuck in her. "Oh no. I can't pull him out." She worried, as Jeff started thrusting again. Her pussy tightly constricting his shaft, she fell to her knees as he came inside her once more. "What am I going to do?" She cried, now going to be stuck as her son's cum dump.
