There's a moment where Izu was about to answer with words, but the sudden tightness turns it into a gut-felt moan and a smaller-than-she's-used-to warm feeling in Derple's ass.<br/><br/>That also signals a very pronounced change in the elf's thrusting. Before it was a bit slow, restrained but steady meeting of hips. After it was a hurried, hip rocking pounding as Izu's face and lips roughly rub against Derple's offered cleavage. Derple might be reminded of Ken's experimental sex toy calibration. But only a little, after all, Ken was a more solidly built dwarf woman and the toy had been activated on accident when she was talking to Derple. Izu is a leaner elf and there's no accidental turning on here.<br/><br/>The ending is probably going to be the same. A smaller third squirt, and then deflation unless Derple really works at it. On the other hand, Izu has a hand already near the right area, and has been fucking Derple. The determined look on the elf's face means that it's quite likely that if Derple asks, the machine will continue where the flesh is weak.
