nipping out 

When your nipples can be seen poking through clothing, often because of cold weather, sexual arousal, or particular types of clothing. Many women wearing bathing suits and sports bras tend to have a problem with this because of thin coverage, feeling uncomfortable at the prominent exposure of their body.

Are you cold? You're nipping out.

Nipplenis

Probably a small penis that's just shrunken, old, and shrivled but you're not entirely sure that it's not actually a really weird nipple after all.

Possibly also could be a forgotten seaside town in a northern backwater that you past through once whilst on your way to somewhere else. It's quite probable that you stopped for a piss but the toilets were locked or out of order.

At what age do you think your cock give up and just goes fully nipplenis on you?

double nipping 

Sorry ladies, double nipping is limited to women with tits large enough to get the nipples close enough together to suck on both of them at the same time.

She loves double nipping, especially while she is riding on top.
