Medium dick

"Oh my god, you're actually doing it. Are you that horny?" Rina said with a mocking tone. Your decidedly average six-incher is pointed straight at your stepmom.

"You asked me to!"

"Just kidding! Let's see- it's just like your dad's! That's fucking hilarious!"

You've always thought you had a pretty good penis, so her mocking laughter was annoying.

"But men who are so **** for me makes me so fucking wet." Rina grabs your erection and cheekily strokes it. "Did you hope something would happen between us?"

Yes was the immediate answer that sprang forth. Even before she became your stepmom, you had been fantasizing about her, so much that you developed a gyaru fetish.

"Do you want to stick this haaard cock inside me? Stir up my pussy?" She was stroking it firmly now, and you were paralyzed by the pleasure and excitement. Your eyes were glued to her massive breasts, jiggling from her movements.

"Rina! I'll be back late today, don't wait for me to sleep."

Your soul leaped out of your body. Your father was standing in the living room, and from his angle he could not see below your waist. Rina hopped over to his side and gave him a deep kiss. You watched with disgust as their tongues coiled together, and Rina even groped his crotch until there was a bulge.

How could she marry a man over twice her age? Both your father and her must be insane. You tucked your cock back into your pants and left for school, feeling disgusted that you even fancied the thought of having anything to do with Rina.

You saw her at school later, but did not speak until you were home again. The girl was lounging on the living room sofa, her panties exposed. They were pink.

"Welcome home Takeru-kun~ Did you have a good day?"

When you did not respond, she spoke again.

"Or were you thinking of me the whole day? You must be so sad we were interrupted." Rina made a jerking gesture with a hand. "You know... you daddy's gonna be late. Whatever happens... he won't even find out."
