Akari and her husband have been living together for three years, but he has never proposed to her. Their neighbor is Michael, a foreign guy. Michael is into exercising, he always goes out in shorts that make his big dick want to burst out of his underwear.

Every time Yui sees Michael, she can't take her eyes off his crotch. One time, Yui was reading a book when she heard Michael calling for help. It seemed like something had bitten him, so Michael wanted her to apply some medicine.

And the bitten spot was... his giant dick! The process of applying the medicine was not very normal. Yui had to repeatedly apply it all over Michael's dick, and after a while, Michael shot all his sperm into Akari's mouth! Shinto and Michael got along very well, so he decided to invite Michael over for a drink....
