She knows she has to lick the head of the penis very carefully to give her partner maximum pleasure. With a slow, precise movement, she brings her lips close to the sensitive head of his penis, breathing lightly to warm it up and prepare it for what is to come. Her tongue begins to explore the head, gently flicking and licking around the crown, where the sensitivity is greatest. She takes her time, making sure every movement is perfect, to give her partner waves of pleasure. Eyes closed, she concentrates on every detail, feeling his cock harden and throb under her touch. Her partner's moans and sighs encourage her to keep going, to bring him to the peak of pleasure with each careful, gentle stroke of her tongue.
