Bunny Mating Season (18+ manga)

Homeless and hungry, a pair of hapless catgirls are looking for a caring new owner, using their tried and true method: the “abandoned cats in a cardboard box” trap. As the cold rain blows in, they’re rescued by a young salaryman who feeds them, giving them the kindness they’ve been looking for. To repay him, they transform and start snuggling up pretending that it’s all a dream. Whether it’s big sister’s petite frame or little sister’s outrageous curves, their new owner doesn’t pussyfoot around as he pumps them full of all the milk they can handle!
