Sure

"Oh thank you! You're so sweet; I'm so glad there are still gentlemen around that'll help out a woman in need." She pushes a whole bunch of junk off a large plastic crate in a single swoop of her arm. "Here, 'ave a seat, make yourself as comfortable as you want."

You sit down. Bertha rolls up right between your legs. She slowly and gently pulls your pants loose, letting them fall around your ankles. She rubs the inside of your thighs with her cold metal claws, which give you goosebumps and shivers. It's very strange, and it doesn't help that she has no emote-able features. You're not even sure where she's looking.

"I know it's strange to be with a woman like me, but I still know how to give a man a good time." She purrs as her noodle arms make their way up to your groin, rubbing and stroking your skin. Her cold touch causes your balls to shrivel and your flaccid penis to shrink back. Seeing that her hands won't work, she twists one of her wrists, switching it to a vacuum nozzle. The suction is warm, and though a little rough, it has no trouble getting your cock up to a hard state. "Oh wow, are they normally this big? It's been so long since I've seen one that I've kind of forgotten. Oh how I wish I still had my warm, tight cunt you could slam into or my big pair of tits that you could fondle and play with, or- or my plump lips you could kiss." Her tone seems melancholy, but she continues to run the nozzle up and down the length of your penis, switching it on and off in intervals, raising or lowering the power, and trailing it in patterns. "Does this feel good hun?" You nod, which makes her brain jar light up with a happy orange colour. Your cock throbs and you know that you won't last long.

"Oh my, you're twitching! Goodness, your face is so cute right now, such a funny face!" She raises the suction to maximum and begins to rapidly working it on your head, the edges rubbing against your sensitive cap. "You're so close, aren't you sugar? When you cum... cum on my brain case okay? I want my only human part left to feel your warmth."

As if on cue, you grunt and push her nozzle out of the way. You stand up and start stroking your shaft like a madman just above her head, pushing her down with your free hand. She does nothing to resist, only moaning softly and breathlessly through her speakers, which somehow just turns you on even more. With a few last hard pounding strokes you cum, splatting a few ropes before dribbling the rest. It runs down the glass dome, leaving streaks and streams of ivory. Bertha seems happy, humming to herself a happy tune mixed with a few moans here and there. You ask her if she can feel your warmth.

"Well, brains don't really have nerve endings, but my temperature regulator just spiked. Oh I can just imagine how good it feels..." She whirrs a tiny bit forward, bumping into you. "I know you don't have much time to stay, but, could you... could you hold me?"

Feeling a little pity for Bertha you get on your knees and wrap your arms around her, accidentally smearing the cum on her brain case with your shirt and getting it stained. She purrs, happily returning the favour.

"Here," she says after a few minutes of cold cuddling, pushing herself away and with a key-card extended towards you in her hand, "take this. It's good you came 'ere first, because you'd be as good as caught if you tried the stairs. This key-card will get you into the room next door. There's an air vent that leads all the way up to the outside world." You take it, bowing your head a little. She clasps her hands together, watching you with unseen eyes. "Thank you. I know it's strange to fuck a lady such as I out of the blue, but what you did means a lot to me. I'd come with you if I could, but I'm not great at climbing, so... you just escape for me, okay? Good luck."
