Technically, that was impregnation.

While we are on the subject, Kira also gets pregnant without doing anything with Chief O'Brien.

Dipping hands into a bowl of glass beads, IIRC.

And then he goes off in engineering about how dangerous a man lift is, because if you hold onto what are clearly hand rails, a support will chop your hand off, and some dipshit is like "Who would put their hands there?" as if you wouldn't grab at the waist high rails riding a lift in a ship that might pitch and roll. They try to play it like he's hormonal but it's a solid point.

Oh yeah and she does NOT make it clear to him that what they're doing is sex (although I suppose you could interpret that as a cultural miscommunication). She's just like oh I didn't think you could get pregnant though I didn't think it was a big deal oopsie!

That show was just soooo horny all the way through.
