[Twilight Road (Tomo)] Boku no Loli Senpai wa Chiisai kedo Ookii Ken

A petite senior with absurdly oversized breasts tries to act as a reliable upperclassman to her junior, but her curvy figure and easily aroused body keep sabotaging her composure. As teasing hands slip under her clothes, leaving her thighs soaked and trembling, she can't help but beg for relief — only to find her kouhai equally eager to return the favor. What begins as an innocent attempt to guide him through school quickly spirals into a fiercely passionate exchange between two hopeless, wildly enthusiastic lovers.
