Her ass.

Deciding to go with pain over pleasure, you slipped into Bella's asshole, finding her tight and unwilling. Wasting no time, you fucked the bellossum in earnest, slamming your cock deep into her ass and enjoying the growing sounds of pain that escaped Bella as you brutalized her. Confident in your new position in control, you reached beneath her to tweak and twist her nipples, adding equal amounts of pain and pleasure to her rough fucking.

Then you felt it. Even in the midst of you hammering into the bellossum, she had employed her special ability. You felt her body draining you, first of your energy, but soon you knew she would be draining you of your cum. What you didn't expect was how good it would feel despite the small discomfort it was causing. Still, you thought maybe you should give this up. You could finish the fight here, but not if you were drained up before you could do your handiwork.
