While reading, mommy catches you staring at her deep cleavage. She decides to give you a little anatomy lesson to teach you about big tits like mommy's. She tells you not to bother with any girlfriends with little titties. Big boobs like mom's are best, and she wants to make sure you know how to handle them. She starts groping and squishing her tits through her top, but realizes you need to see them better. After taking off her top, she deep-grabs her breasts more, fondling them through her bra cups. But still, she knows her son needs to see it all. She takes off her bra, and you see mommy's big udders in all their glory. She teaches you how to play with big breasts and play and pinch at the nipples to turn any girl on - while getting quite turned on herself. By the end, she's slapping her breasts together and jiggling them when you cum in your pants! Mommy is flattered, but you have to save up that cum for the next lesson on tittyfucking.
