[Chinchintei (chin)] Eirin Sensei Formula Miss (Touhou Project)

Eirin Yagokoro is interrupted by Reisen Udongein Inaba, who announces that M-Meirin's already touched you too much. As Eirin examines your condition, Reisen watches closely, offering to use her medical tools to help while the bearded pharmacy owner prepares sedatives and stimulants for the patient. Soon the voluptuous doctor is gripping her bouncing breasts and pleading to be made a babe, calling out to her auntie before begging you to fill her mouth in the privateroom. Afterwards, a panting Eirin admits she can't believe her lewdness while Reisen uses the very toys from the Eirin-chan box to demonstrate how to give pleasure, leaving both women flushed and wanting more.
