If the power transferred thru body fluids wont misono have them when they did french kiss,...

Yeah. I think saliva of his is sure enough since its also a body fluid, or lick him while his sweating. Haha.

My guess is that Misono didn't go to the bathroom after the act, and still had cum inside. The numbers dispeared after he went to the toilet.

I don't think saliva has as much dna as 'ahem' and he had more of it than saliva so I think that's why he didn't get it that time.
