No

As horny and addled as you are, the mimic just said you'll probably die if you don't take a break. The fear of **** is enough to let you work up to a refusal, and you shake your head weakly.

The mimic pouts, giving you a reproachful look. "But I want to do it~."

In a departure from her earlier teasing, in which she made you ask for it, the mimic goes for a direct approach, nearly kissing your throbbing member.

"I want to suck your big...hard... cock."

As she speaks, her eyes gaze up at you imploringly, as if she might cry if you refuse. Her mouth opens invitingly, tongue hanging out, but not quite making contact with anything.

You swallow, your pulse racing as you try to remind yourself of the consequences for giving in. It's hard though; your head is swimming, and you can still remember how good it felt to fuck her mouth earlier...you don't think a human's throat could squeeze on a cock the way hers seemed to.

Her eyes are locked onto yours the whole time, and from the knowing grin on her face, she can tell you're wavering. "I'm really good at it, you know? It'll feel at least twice as good as when you were moving on your own...~ Just nod~" She closes her mouth again, moving even closer to your cock and not-quite-kissing the tip.

You can practically feel your balls working overtime to make more cum, and a bead of pre-cum oozes out the tip, only to be promptly licked off by the mimic...the light brush with her tongue makes your whole body spasm for a moment, and the pleasure is so intense you nearly ejaculate...the trace of aphrodisiac-laden saliva left behind on the tip of your cock makes your current situation all the more unbearable, and you can't help but whimper...

Maybe you should just nod your head...you reason to yourself that with how horny you are, you won't be able to relax anyway! Maybe after you cum once or twice you'll be able to take a break...a small portion of your brain tells you that you definitely can't afford to nod, but it's hard to remember why...
