Training The Librarian In Glasses

While studying at the library one day, Ryosuke catches sight of a man who resembles a friend he had back in high school. Kei was a bespectacled boy more interested in books than people, but somehow the two had become friends. However, when messing around at Kei's place one day, Ryosuke ended up making Kei pee his pants, and both of them got hard as a result. Following that, their friendship fell apart, and Ryosuke feels a sense of regret over it. When the two reunite, it seems that Kei has developed a new fetish... and Ryosuke can't help but get drawn back in.
