Reunited after 10 years, my niece Sana has grown up, yet still has her childish side, wearing an open tank top with no bra, making her nipples clearly visible. Despite her appearance, she acts like she used to, flashing her chest freely. Realizing I'm aroused by my niece is troubling, so I try to leave under the pretext of taking a shower, but she insists on joining me, saying we've showered together before. She offers to help wash me, and as she rubs her breasts against my back and arms, it feels good. Soon, her hand slides down to my crotch, and she starts to stroke me firmly. I try to stop her, but she just says she's still washing me. She notices my erection and teases me, then suddenly takes my large penis into her small mouth. Her tongue skills are surprisingly good, and she seems experienced, possibly due to having a boyfriend. She offers to do more, and uses her breasts to pleasure me, making my sense of ethics fade in the face of such pleasure. She asks me to make her feel good too, and I switch places with her. She reacts enthusiastically to my licks on her nipples, and I continue to pleasure her. Eventually, I insert my erect penis into her young vagina and thrust deeply. After a vigorous session, we move to the changing room and continue in a riding position, where her intense movements quickly overwhelm me, leading to an internal ejaculation. She cleans up the spilled semen with her mouth, and I quickly become erect again, starting a second round. She rides me from behind, aggressively stimulating my penis, and teases me about its hardness. I climax again inside her. Before I can catch my breath, she asks for a third round, and despite feeling tired, I continue in a normal position, finally finishing by pouring the remaining semen into her vagina.
