My mom, Yuka Tachibana, has big breasts that I can brag about to my friends. Of course, I love them too, and today I get to suck on them as a reward for massaging her shoulders! She gently strokes my erect penis with her hand, and when we take a bath together, she washes it with her breasts. And today, she taught me about sex. It was different from usual, and it looked like mom was enjoying it too. Recorded in digital mosaic.
