ピチふぇち！だぶる!! ～競泳姉妹と中出し孕ませにゅるにゅるデート♪～

Takuma was in agony over a problem...
That is, he couldn't reach orgasm inside a girl.
Yukari was the prettiest girl at school, and he'd somehow managed
to succeed in confession his love to her... but now what?
His body was his own enemy. He couldn't go further.

At that time Yukari's little sister Kana discovered Takuma's secret fetish. He loves girls in tight, dynamic racing swimsuits. "Hey, if she wears that you can cum inside her, right?"
