[Synopsis]

The protagonist (36) receives a suspicious bottle of water from his parents and is told to drink it to improve his physical condition.
He reluctantly accepts but somehow, since he started drinking it, he's clearly feeling better.
And, most importantly, he feels like he's becoming more popular...!!
If the water is making him popular, he'd better use his popularity before it wears off!
He seduces and fucks the most busty beauty in his company, the beautiful trainer at his gym and a high school gal he meets on his way to work!

There's no four-person action in the main story but there is a dream-like four-person action in the bonus.
