Giving a woman lip service is to use your lips, tongue and mouth on her vulva with intent to bring her to orgasm, as she rightfully deserves.
His enthusiastically gave me some of the most sensational lip service, causing me to buck uncontrollably.
His lip service was so heavenly I could have swore I died and became reborn again.
He asked if I wanted his lip service in exchange for prepping dinner so I eagerly agreed since I don't mind cooking.
