Your girlfriend, a sexual dynamo, starts by stroking your cock with both hands, her grip firm and rhythm steady. She then leans in, her tongue flicking out to lick your tip, tasting your pre-cum. She takes you deep into her mouth, her head bobbing up and down, her lips tight around your shaft. She alternates between sucking you hard and giving you gentle licks, driving you wild with desire. As you're about to cum, she takes you out of her mouth, stroking you rapidly until you explode, your cum shooting onto her face. She smiles, your cum dripping down her chin, a sight that makes you ache for more.
