suck n' tuck 

A blowjob discreetly performed in a public place.

The female will covertly pull out the male's penis, suck and then tuck it back into his pants upon completion. The public is none-the-wiser.

Julie gave me a suck n' tuck under those round tables at the Chinese restaurant.

Tuck N' Suck 

The Tuck N' Suck is a term that has been coined to describe an innovative sex position invented by Colt Brennan, quarterback of Hawaii. The procedure is for the man to spread his legs and tuck his penis between his legs. Then the female sucks the man's dick. Naturally, due to the circumstances, the female's face will be extremely close to or in the guys butthole.

Hey will you give me a tuck n' suck?
