...The sound of Jen's mother opening the door snapped the two from their sexual trance. They glanced at the
clock: 2:30 PM. Their mother was home early!
Reality hit them both. What were they to do? The smell and sights of the mess around them was sure to tip
their mom off. It smelled like a brothel and looked like a horse had an ejaculating contest in the room.
Jen's hair was a tousled mess, and she was covered in semen. Alison wasn't in a much better state, and worse
still, had no excuse for being home. The two sisters threw on baggy shirts from the closet, held each other's
hands and prayed.
Jen's mother stopped at the door to Jen's room. She opened it and looked at the two with a look of
exasperation that dashed any hope the two sisters getting out of this scot free.
“Je--” Jen's mom cut herself short; Jen's cock stirred in her mouth, pressing against her teeth as if it knew
what would have come. Jen opened her mouth to let her cock poke its head out.
“You. I should have known you weren't sick, honey. I can't even remember the last time you were sick since
you hit puberty. You fake being sick and then you have these day-long masturbation sessions. And judging
from what's dripping from between your legs, you managed to fuck yourself. Don't you know you could get
pregnant?” Jen could only hang her head in shame and half-mumble an apology around her cock-tongue. Her cock
twitched as if it was satisfied with itself, sticking out more and forcing Jen's mouth open wider.
“Alison... Ever since you started maturing you've been trying to get at your sister's tongue-cock. Every
time your sister faked being sick you tried to get out of school that day so you could try and get her to have
sex with her. You know she's got little control over her body!” Jen's nipples hardened as if in answer. Jen
blushed. Alison looked at her feet.
“And you know you could get pregnant from fucking her. You know there aren't even condoms that could fit your
sister. And you know that saying her name makes her instantly hard, need to cum and grow another inch for a
day.” Thank goodness for small favors, thought Jen. She had memories of growing too large for any woman to
handle!
Jen's mother sighed, then continued. “Since neither of you seem to want to listen to me, I'm going to have to
punish you both.” Jen and Alison looked at each other nervously.
“I'm taking a couple weeks off of work. You will both be called off of school as well. You, my sweet,” she
said, putting her hand on Jen, “will be fucking yourself and your sister until you're both pregnant.” The two
sisters looked at their mother in shock, and then at each other.
“And to teach you a lesson, you're going to impregnate me first.”
Jen's tongue-cock stirred to attention, pushing itself out of her mouth. Jen looked at her mother, a mixture
of nervousness and horniness in her eyes.
