Why not?

"I think I can help you understand what you're feeling."

She raised an eyebrow. Why would this stranger understand what she was feeling?

"A second ago, I gave you a powerful dose of a very, very rare substance. How does that make you feel? Be honest."

She thought. "Honestly, kind of good. Why does it feel good?"

He responded with another question. "How does this make you feel?" As he finished the sentence, he reached out and pinched one of her nipples hard enough to hurt even through her shirt and bra.

"It felt fine. Actually, it felt sort of good too." The pain had registered, but for some reason she didn't mind it. It was like a hot shower on a mild sunburn or the pleasant soreness from a really good workout.

She reflected on the conversation so far. This stranger had approached her at a metro stop, poked and prodded her, interrogated her, and admitted to drugging her. Yet she was unnaturally calm. She knew this should be setting off alarm bells, but it wasn't.

"Ok, there's clearly something really strange going on and you seem to know something about it. Why don't you fill me in?"

He grinned. "I thought you'd never ask." He explained the phenomenological anesthesia to her carefully. She waited patiently till he was done, then asked several follow-up questions.

"How long does it last?"

"Fortunately for you, this recipe will never wear off. You'll never feel anything negative again. No sorrow, anger, pain, or regret."

Jane considered this. "Why me?"

He shrugged. "You're hot, and you seemed really dejected. I was curious how it would work."

She immediately picked up the subtext. "So you've never done this before?"

"Nope. First time."

"And presumably you're expecting some sort of sexual gratification?" She asked archly.

He smirked. "Does that bother you?"

"Obviously not. So what now?"
