Pleasure and pain: the ritualistic analogous dance between sorceress and monstrous beast

In an 8K quality, full-color image, a grand room within the castle walls. On the floor, a large pentagram with runes, lit by magic candles in each corner, each of a different hue. In the center, a 45-year-old sorceress, her thin waist contrasting with huge sagging breasts, stood bent over, her very long, thick wavy blond hair cascading down. Behind her, a towering ancient anthropomorph black monster with an imposing dick was engaged in anal sex with the sorceress. Her eyes rolled up, mouth open in a mix of pleasure and pain, embodying the 'ahegao' look. The scene was captured from the side, both their full bodies visible within the frame.
