[Taiyako Takoyaki (Gonzou)] Rina to Riku to Tagosaku [Full Color] [desudesu]

A wide-eyed blonde with adorable twintails throws herself into her first time with an older, well-endowed partner, needing "sex training" so Riku won't be disappointed. She eagerly takes him in every hole, even begging for a creampie and dreaming of making "lots of babies" after her belly begins to swell. The story traces Rina's sweet, eager journey from nervous virgin to blissfully pregnant lover, her small body contrasted against her muscular stud's size.
