[Plain J-cup girl × Lustful middle-aged teacher] Ignored by teenage boys who don’t appreciate real feminine charms, this low-caste plain student. But only the pervy teacher noticed her hidden bust. During school trip free time, while others went out, he targeted lonely Hyakuta in her room under “life guidance” pretext. Teaching her first paizuri, facial blowjobs…molding her to middle-aged tastes. They spent all free time in passionate sex until the trip’s end.
