Three Hours Later

You were back in the kitchen and investigating the fridge when your aunt tapped you on the shoulder.

"It's been three hours," she said, a nervous smile on her face. You grabbed a can of some weird green tea your aunt had practically stocked every shelf with and shut the door.

"Okay um... I'll get another checker ready and you can give me your sample," you started casually, snapping the can open with a hiss. She followed you to your cases that were setup again on the kitchen counter. She watched you pull another dildo piece from a box, still wrapped in clear plastic. For a moment you considered asking to take the sample from her yourself, just as a joke, to see the look on her face, but you thought better of it. You screwed it onto the machine base on the counter then pulled the plastic off like you had done a really lame magic trick. "Tadaaa..." you added.

She gave you a smirk then took the device in her hands, staring at it possessively.

"Okay I'll be right back," she said, shuffling off to the bathroom in her tiny green shorts. Suppose she was still embarrassed about earlier. You had only held out a tiny sliver of hope that she would once again shove the dildo into her pussy right in front of you anyway.

"Only need a small sample," you called after her, not above providing your aunt cheek. "A quick sample!" You sat down for a few minutes on the stool, waiting patiently and sipping the surprisingly tasty can of tea. You were studying the ingredients label on the side when your aunt returned not long after.

Her cheeks were pink again and she shuffled out with the sampling device in one hand and a folded up towel under her arm.

"I... er...I..." she stammered, apprehensive about handing the device back to you as you reached for it. You frowned until you looked at the device and saw that the dildo was dripping wet. Your aunt's fingers were shiny and she quickly brought the towel up and wiped at the bottom of the device again, smearing the screen a bit. "S-sorry..." she said, a little out of breath, "I didn't mean to... I just... all of a suddenly...and so fast... I couldn't...." You stared at the thing, the smell of it finally hitting you, a profound scent to the fluids that were distinctly of your aunt. You swallowed, trying not to flare your nostrils, your aunt still stuttering in painful embarrassment.

"It's waterproof," you said, maintaining your composure somehow, "kind of has to be." You took it out of her grasp before she could decide to run away and bury it in the backyard or something. Your spine tingled when you felt a few drops of liquid run down your knuckles. Remaining professional and fast with your fingers you tapped the marred screen and began analysis. There was that whirr again where the porous plastic began to absorb the sticky liquids coating it. It whirred for an extra long time, your aunt noticing this which made her squirm. Shifting uneasily in the chair to the hardening in your pants you tried to concentrate. It was like the more uncomfortable your aunt looked the more turned on you got.

Finally the machine ceased its whirr, the sound audibly squelching to a stop. Your aunt craned her neck over your shoulder trying to decipher the complex readings and you let her worry for a while as you pretended to frown at the results.

"Well?" your aunt prompted impatiently. You held out for a few seconds longer before letting her breathe.

"It looks good," you said, putting the device back down onto the counter. "The marker numbers are in a good zone, indicating a slowed rate. I think that bit of... boost you gave yourself this morning did the trick. I'd say you can probably go the rest of the day without another load, until before bed time."

"Yes!" The woman jumped, punching the air. You'd never seen your aunt so happy about knowing when her next load of cum was due. "Who knew masturbating could save my life?" she said cheerfully. Her relief made you happy too, if a little sad for your little man, but you loved your aunt and was glad for her despite it. "I'm making you a big lunch!" declared your aunt suddenly. That didn't sound too bad.
