Tsukushi suddenly visits her older brother's place, eager to catch up after their long separation, peppering him with questions about his life lately. As she talks, her affectionate nature draws her closer and closer to him. Starting with light skinship, she playfully flips her skirt, pulls up her top—her warmth and familiarity impossible to ignore. Her brother, touched by her closeness, begins to feel his desire rising. He runs his tongue along her neck, groping her breasts with both hands, escalating things quickly. Even as Tsukushi says, "Big brother, we shouldn't be doing this," her excitement only grows stronger. She grinds a vibrator over her panties, teasing her wet pussy relentlessly. Overwhelmed by pleasure, she can barely resist. Her brother taunts her, "Look, your panties are all stained!" Lifting them aside reveals her smooth, hairless slit, soaked and glistening. So wet that anything slips in easily, he starts treating her like his personal toy. She sticks out her ass, posing like a doll, trying to take fingers, dildos, even cucumbers into her mouth. She protests weakly, but there's no real refusal in it. After bringing her to a powerful climax, her brother wastes no time flipping her around and shoving his cock into her cute mouth for a blowjob lesson. Despite her clumsy tongue, her earnest sucking moves him deeply. Of course, such effort deserves a reward—time for 69. They greedily lick each other's genitals, deepening their forbidden bond. Then comes their ultimate collaboration. "It won't hurt, it's okay," he reassures as he enters her smooth, tight, immature pussy. Spreading her legs wide, he savors the view before starting steady thrusts. They try every position—doggystyle, cowgirl, missionary—savoring the intense closeness. Finally, he finishes with a facial, blasting cum all over her face. What did first-time cum taste like, Tsukushi? *Note: Images are for illustration only and may not reflect actual content.
