light french kissing is just that - light french kissing, its open mouth, a little tongue action but you aren't trying to lick the girl's tonsils.

Deep french kissing is alot of tongue action.

dfk is much more enjoyable..some providers like lfk..some wont kiss at all..i prefer the dfk route..i enjoy it and if my provider enjoys it too..all systems are go..the session is much more intense and intimate..most providers will tell you they prefer that..
