Draw my yuri moms Maya (the blond mom) and Irene (black haired mom) here: https://i.imgur.com/2HGYPWW.jpg , as scantily clad topless cavewomen in prehistoric times outside a cave near a lake? They should both wear thin G-string loincloths with nothing covering the buttocks.
Maya the blonde is 170 cm tall and has a flat chest and no pubic hair. Her clothes are leopard print! She is holding a spear!
Irene the black haired mom is 168 cm tall and has big F~I cup breasts with sparse pubic hair. Do not forget the wedding rings for them. Draw them in a sexy happy yuri moment!
You can add teeth necklaces, make them wear skulls, and/or body or face paint. Most importantly, make them sexy!
