Tsubaki in Izayoi form completely naked, proportions same from other commissions. Litchi is a futa.
1st panel: litchi is fucking Tsubaki like in the image but instead of biting her nipple, she is sucking it and there is milk dripping from her mouth. Tsubaki has red pubes, and Litchi has no pubes.
2nd panel: Litchi is fucking Tsubaki from behind while she is being pressed on the glass exactly like in the image. Her breasts, arms and face are being pressed on the glass. Litchi is holding Tsubaki's ass with one hand, and with the other hand she is grabbing Tsubaki's hair. You can zoom on Tsubaki so that you only need to draw Litchi's legs, dick and arms.
