Everyone has some insecurities that plague them. Our protagonist is troubled by the size of his equipment. Day after day his friends regale him with their stories of their astronomical packages. Their stamina, unmatched. The length, unrivalled. Allegedly, if they really tried, a single load would rival an ocean in volume. Unfortunately, our self-conscious self-insert really takes all these stories to heart, feeling quite inadequate, until one fateful day when everything changes!

It was simple really, he was overcome by the masculine urge to adjust his modest manhood, when his friend's mom catches him in the act. She pulls him aside to give him a piece of her mind, which lucky for him involves some friction.

As she is telling him off for fiddling with his phallus, she has him in a choke hold with her mommy milkers mushed up against his back, causing a totally normal reaction from a visual novel protagonist. His rod rose to attention at the slightest stimulus. He braced for the worst, fully prepared to take his friend's mom's mocking of his member size, but it never came.

Instead, Atsuko is flushed red, breathless, in AWE of the size of this... this MONSTER COCK! And she wouldn't be satisfied with just looking, no-no, Atsuko needed a taste of this once-in-a-generation dick. What if this was a fluke? What sensible person wouldn't want to get a second, third or fourth opinion? Better ask the other MILFs what they think!
