Serana Volkihar (Skyrim) and Rean Schwarzer.
Both naked.
Serana must look like in this picture.
External
Sitting cowgirl position.
Rean is sitting on a chair and Serana is sitting on top of him in reverse cowgirl. Like in this picture what
bible-black-orgy
Except that Rean is sitting on a chair and Serana is sitting on him.
Rean has one hand on one of Sérana's breasts and with the other, with his fingers, he spreads her vagina lips.
Serana with one hand strokes one of her breasts.
She has an expression of pleasure. And so does Rean.
Serana's eyes can be blue if you prefer.
Title: Intense pleasure!
