In a cramped, dimly lit closet, Felipe's sister eagerly unzips his pants, revealing a thick, throbbing cock that's impossible to resist. She hungrily takes it into her mouth, savoring the salty taste of pre-cum as she bobs her head, her hands cupping his heavy balls. Felipe groans, his fingers tangled in her hair, guiding her rhythm as she deepthroats him with enthusiasm. Their taboo lust grows, fueled by the forbidden nature of their act, until they're both ready to explode.
