[PHkengai (Takaoka Nanaroku)] Makimono C (Daiya no Ace) [Diamond Drop Scans]

Eijun Sawamura guards a rolled gift from his mentor Chris Yuu Takigawa like a state secret—'don't open it here!'—because the master's so-called textbook holds lessons the exhausted pitcher plans to try out the moment his roommate leaves the room. Chris decides theory isn't enough and gives his flustered student a hands-on demonstration, kissing him deep and stroking his slick, trembling length while murmuring for him to concentrate and think only of him. Sweat-slicked and gasping that all he can think of is his senpai, Sawamura learns that his master's guidance on any matter extends far beyond the baseball diamond.
