First half of the pic: R. Mika in this position:
External with exposed breasts, bottom parts and barefoot, with one hand tweaking her nipple and other holding her thigh, passionate expression. Poison's body partially appears in the right side, trap version naked with penis (full package) and nipple erections.
Second half: the two characters in this position:
Image with Poison wearing only her hat while Mika's still wearing her mask. Same body proportions from the game (size, musculature, and so) with slightly larger breasts for the two.
