[Sakai] Sexual Experimentation Practice!

Two busty schoolgirls flash their student IDs before an intimate extracurricular lesson begins, a lone male putting their eager, curvy bodies through kissing, riding, and deep penetration that leaves the masked Hinamori and her flashy friend gasping for more. When one girl pouts that sharing his lips isn't fair, the session melts into a tangled three-way kiss mid-thrust, the pair competing for his attention even as he praises their stamina and reminds them their performance still needs plenty of practice. The final exam has both beauties working together with tongues and lips in tandem, proving these studious vixens learn best with their mouths full.
