Sinopsis
My mother, Yuuka Tachibana, has breasts so massive that I can brag about them to all my friends. Of course, I love them too; today, as a reward for giving her a shoulder massage, she’s letting me suck on them. She gently strokes my erect penis with her hand, and while we share a bath, she even washes my body using her breasts. Then today, she taught me something called "sex." Unlike the usual things we do, Mom looked like she was truly enjoying the pleasure herself.
