[Fei] Pants Down, Young Master! It’s Time to Learn Sex (COMIC Penguin Club 2021-07) [cutegyaruTL]

A composed maid named Sari receives an unusual order from the mistress of the house: personally instruct her sheltered young master in the art of sex, and she treats the lesson with the same cool professionalism as any other duty. She bares her enormous breasts and heavy areolae for his first trembling paizuri, coaching him on stamina before guiding his virgin length inside her and walking him through every thrust. Once the lecture gives way to practice, she takes the lead in a relentless cowgirl session, riding him with her thick thighs and big ass until the overwhelmed boy learns just what his body—and hers—can endure.
