In the sultry heat of the family pool, Yunagi's swimsuit-clad body glistens as she leans in, eager to taste her stepbrother's throbbing cock. She begins with a tentative lick, her eyes fluttering closed, before taking him deep into her mouth. Her wet hair clings to her face as she bobs up and down, her tongue swirling around his tip. Meanwhile, her hand explores her own body, fingers slipping beneath her swimsuit to tease her clit.
