SW-639 Seeing a woman in a bookstore showing her underpants to a serious student looking for a reference book, she's selling books, underpants and breasts, a slut's wife like that, scratching her ass with a hard-on stick, sneaking in without the shopkeep

The smugness of a serious male student looking for a reference book in the bookstore, the deliberate display of book A in front of her eyes, the excitement of his underpants beginning to turn up, the excitement of a male student's lower body beginning to rise up in a small shop with a mini-skirt full of ass, the holding of a cracking meat bar, and the penetration of the shopkeeper and other guests.
