He's right that she'll be super sensitive. Every little touch is amplified to be so much more, and he's not allowing her even the slightest bit of rest in between. She's sweaty, she's panting, she's swollen and stretched in every way... and he's not letting her rest until he's stretched every part of her. The tentacle pressing to her cunt gets her attention, and she tries begging for... something, anything, but doesn't get much out.

"That's... t... too much..." She says it, but trails off into a moan when the tentacle slips into her. "Oh... Oh god.." she manages out, her body shivering visibly in his grasp as she feels herself stretching wider and wider around him. He'd picked the right direction for those suckers, because her length is suddenly rock hard again and in need of the attention he'd offered before. She's at his mercy, she knows it... and he knows it. He could do anything he wanted to her, and she'd love it.
