Not trying to be cheesy but, this works for me.
Before going out to dinner with my husband I simply get him to suck on my lips. He has mastered it! When he sucks on the top lip he pulls out but, mostly in an upward motion. On the bottom lip he will pull out and in a downward motion. We have been married for over 10 years and we still love it. He really, really enjoys doing this and he loves the way my lips look afterwards and while we are out, it is a really big turn on for him to look at my plump lips and imagine sucking on them. This makes for an interesting evening, enjoyable for us both. I kind of hate to tell my little secret but… Maybe someone else will benifit from this ‘HOT TIP’ !
