[Sena Youtarou] Houkago to Senpai to (COMIC Penguin Club 2021-10)

A nerdy young boy named Maki-kun discovers his dusty old school storage room is now the secret hideout for the busty, older senpai he secretly admires. Their innocent after-school chats in the quiet library quickly escalate into a intensely steamy affair, with the eager schoolgirl eagerly servicing him and using her soft, pillowy chest to bring him to climax before begging him to fill her completely. The story culminates in a risky, creampie finish caught just before a schoolmate almost walks in, leaving the lewd, freckle-faced couple flushed, breathless, and desperate for more of their forbidden rendezvous.
