This kit can be used for anything really. Foreplay, if you wanna jiggle your breasts at your partner to show the tattoos around your nipples. Get it as a gift for someone if that pleases you.
The best time I believe to use the entire kit, is during foreplay/sex.
As long as you don't mind tattoos on your breasts, you're good to go with this kit.

The texture, for me, was a little thin. It easily came out of the bottle it came in. It ran very quickly off my finger, and since it said it was edible, I actually used my tongue and mouth to get rid of it, stopping it from going down my arm where it was heading.
I rather have something that doesn't suddenly move off my hand, finger, or any part of my body.

I didn't notice a smell, and neither did Andy, my husband, but when I cracked the box open, and tasted it for myself my first thought was Novacain. It numbed my tongue and my nipples a bit. My husband didn't really get a taste out of it while licking it off of me.
He said, and I quote, "I don't taste a thing." That was a bit disappointing because we love flavored lubes, and it says on the box that it's, "Delicious."

It says on the box that it gives a tingling sensation and more when you or your partner blows on your nipple, and it gives a warming sensation.
I easily got the warming while my husband sucked on it, it made it more sensitive, but the tingling..nada. I didn't get a thing, I didn't even feel air on my nipple with the stuff on it.
It lasted the entire time, and to the point I was trying to lick it myself! I enjoyed the warmth very much. We didn't have to wash it, he pretty much took care of that.

I would have loved to feel the tingling sensation, but I didn't. Other than that, I would use it more often now.

The tattoos on the other hand say they take 15 seconds. Keep your cloth pressed to your breast/body for a good minute and then some, 15 seconds doesn't do it. I noticed some cracking in the tattoo's themselves well into the night, and today they are faded, cracked, but still there, no matter how hard I swiped at it.

The bottle of Nipple Lube and tattoos came in a small blue box that clearly said: Tickle Her Nipple Kit. The tattoos themselves are sort of discreet. The two flowers, two heart clovers, three butterflies, and cat could be mistaking for ANY kind of tattoo, but the Purple Flowers and Red Hearts are clustered to make a hole in the middle for the nipple to show through, so some people may wonder why a tattoo would have a donut like look to it.
The lube came in a small bottle that can be stuck in a drawer in the bedroom.
The box itself clearly states what it is, so to me, that's not very discreet. It shows the Red Heart breast tattoos, the red butterfly, and a black cat with the lube, and a woman wearing a skirt, some thigh showing, and her top gone, touching her nipples. That makes it VERY obvious.

I would recommend it to those who would like a little warming sensation on their nipples, and for those who like tattoos. But really, I wish the price was a lot better, for 10 bucks I didn't really get much.
