"No…though an e-stim dildo could be fun now that you mention it…" Emma made a mental note, "but this one is guaranteed shock free…and even if it wasn't, it would be like two volts and fifteen milliamperes, you'd barely feel it."

I don't know why someone being this nerdy about the filthiest stuff was turning me on so much, but I wasn't going to question it. "Alright, yes, to be crystal clear, I give you full consent to fuck me with your experimental dildo."

"Excellent." Emma said, getting ready and putting the harness around herself, the dildo jutting out. Emma walked toward the bed, "let's start slow, so I can find all the right settings…"

“I’m pretty sure I can take it no matter what, Emma.” I said.

“You say that, but you never know…” Emma grabbed my knee, angling my legs open while she observed the dildo. Emma hit a switch on the harness, and the dildo vibrated slowly. "OK, let's try the range of sensation I can give you…"

The dildo hummed against my thighs, the warmth and sensation making me swoon a bit. I wanted to press into it, but knew it could ruin Emma's experiment.

"Can you, umm…guide it in? I'm actually pretty blind without my glasses and I haven't put my contacts in yet." Emma said.

God, it was so adorable. I smiled and took the dildo into my hand, feeling the strange motion along the shaft. It was definitely moving and pulsating differently than anything I'd ever used before.

I pushed the dildo into myself, feeling it vibrate inside of me. "Ohh…" I said.

Emma bit her lip, looking at the dildo sliding inside of me. "Good?"

"Fantastic." I said as I relaxed to let more of it in.

Emma looked at me with a slight hunger in her eyes. "Alright, I want to start slow. Let me know if anything feels uncomfortable…"

"God, nothing about this is uncomfortable, Emma, it's all really nice." I felt a change in the pattern and my body tensed at the novelty. "Oh…wow…oh my god, Emma, this is unbelievable."

Emma's mouth twisted in concentration, and then she reached for her phone. I had completely forgotten that she was keeping meticulous notes on me. I blushed, knowing I was a subject, but in a really exciting way. "Mind if I make notes?"

"Do whatever you want…film it, I don't care." I said, utterly giving myself to Emma's experiment.

"That can be an option in the future, if you want. For now, let's just work with the data I already have." Emma's phone beeped, a log of notes in it already.

"Am I giving you good data?" I said, my ass squirming against the soft sheets, the vibrator giving me waves of pleasure.

"The best data I could hope for. How is your response, tell me more about it."
