[mim'im (Mimisuke)] Prime Study [cotrans.touhou.ai]

Plum-chan, a shy cow girl blessed with impossibly huge breasts, is enrolled in a very hands-on curriculum where becoming a 'proper cow' means learning to crave every touch. Her study sessions escalate from trembling fondling lessons under her zookeeper's watchful eye to slick paizuri practice and eager cock-worship, her lactating chest and flushed reactions betraying how much she loves her training. By the final exam the whole farm joins in, with Plum-chan riding her bull cowgirl-style until she's left dripping, praised as the herd's devoted goddess.
