Eager 18-year-old stepsister, hungry for experience, treats her older sister to a passionate blowjob. Starting with a teasing handjob, she strokes her sister's hard cock, feeling it pulse in her small hand. She then takes it into her mouth, swirling her tongue around the head, tasting the pre-cum. She deepthroats, gagging slightly, before picking up the pace, her head bobbing rapidly. Her sister's moans encourage her, and she feels the cock swell before the first hot spurt of cum hits the back of her throat. She swallows greedily, licking her lips to catch any drops.
