Gourmet Guild's Shrinking meds (Patreon)

Gourmet Guild went through some issues while eating weird mushrooms they found, only affecting the male in the group and girls had to find a way to bring him back, luckily the found the meds had to be administered via the rectum.

Karyl: "Are we actually doing this?!"

Kokkoro: "My lord came a healthy amount, just a little more and this medicine should bring you back to your normal size"

Pecorine: "After you take your meds you'll be a strong and healthy boy"
