[Kasetsu Makoto] Gakuen Ura Service (Seishun Guidance) 2-5

Kouta-kun is an honest, easily flustered student who can't maintain his composure under pressure, so his cool, glasses-wearing classmate offers a secret Gakuen Ura Service to teach him how to eliminate distractions and perform at his usual level before the 20 minutes run out. Her hands-on guidance begins with whispered praise and teasing body contact at his desk, then quickly intensifies into trembling thighs, heaving breasts and slick, intimate lessons of fingering and grinding cowgirl that test every inch of his endurance. As buttons pop, sweat beads and breathy moans echo through the empty classroom, the relentless, pleasure-soaked tutoring pushes him to prove whether he can hold steady or will lose control to her devoted, tightly-clenching service.
