[N yama] Shukushōsarete pantsu no naka o sōjisaserareru manga [Full Color]

A young man's innocent errand to buy a bouquet for someone special ends the instant a smug scientist zaps him with a shrinking device, pocketing him with the declaration that no one will notice another man gone. Fitted with a control chip in his ear and threatened with his little sister and family taking his place, he's ordered to lick her unwashed body clean while she sips tea and praises what a nice holiday she's having. What begins as a terrifying abduction settles into her casual routine — carrying him around town sealed inside her filthy panties, using his struggling body until she cums, and cheerfully announcing that from tomorrow he'll be servicing her every single day.
