She doesn't actually expect him to pull out. Honestly she was expecting him to have his way with her for much longer, but honestly her pleasure-addled thoughts were conveniently forgetting his injuries. She likely would get exactly what she expected once he was in better health, assuming he was still interested in her. But she intended to keep him around, so she'd have the chance to seduce him as time went on.

Time, though, is something she's happy she has here and now. Because when he pulls free of her, her body doesn't immediately recover from the ordeal. To say that she's messy is a massive understatement. Every bit of her skin is coated at least a little and her thighs are even more of a mess. She floats freely in the water until enough of her senses come back, and she slowly pulls herself back to the ramp. Even as her body does its best to recover, the large swell of her belly is a tell-tale sign of how full she was earlier. She'll be a mess for the next few hours as his spunk finishes draining drom her, but she's not going to complain honestly.

When he wakes up again, he'll find her sprawled out naked, reclined against several cushions. Most important to notice is the bit of plastic below her thighs and the carefully placed glass which is about half full of spunk. Plus, of course, the four other full glasses off to the side. She's keeping them for some reason or purpose, and from the much smaller roundness of her belly it's clear she's almost done this time.

Hopefully he's proud of himself.
