A late bloomer, Caduceus is going into his first rut. Only as it turns out, its dangerous for a Firbolgs health to go through a rut unmated, and with Caduceus being ace, he can't make himself share a bed with someone. The solution? A strong sleeping potion and permission for the Nein to do whatever they please with him for the next eight hours.

Options: non-human genitalia. Knotting. Multiple orgasms. Maybe unrequited Fjorclay with Fjord taking this time to be close to Caduceus in a way he otherwise can't.

Have fun!
