I did something like this to a girl in Japan once.
Was walking home when I saw one of my students. (all adults, post HS)
She had just parked her car and after talking for a bit, she invited me in.
Beer, potato chips with togarashi dip (togarashi chili mixed into Qewpie mayonaise), so then she wanted to feed me a chip.
I fed her a chip, and then I told her to close her eyes as I gave her another chip with my lips.
Yeah, she was my lover for a good while after that. Made English lessons that much more interesting.
