Konomi ja Nai kedo - Episode 2

Frustrated with his sterile environment, Ritsuki corners his sister, Kyouya, who is struggling with her own conflicted sexuality. Their initial aggressive argument quickly devolves into sexual tension and intense flirtation. They openly acknowledge their physical attraction to each other, revealing a history of sexual encounters they once had. The escalating sexual frustration leads to Ritsuki forcing Kyouya to undress, culminating in her giving him oral sex. Ritsuki becomes fully erect and, unable to delay, he inserts his cock into her vagina, triggering her premature orgasm. She is still cumming while she handjobs him, allowing him to reach a powerful climax. They move to a different position for more intense sex, with Ritsuki squeezing her vagina as her pleasure peaks. Post-coital, Kyouya tries to deny her attraction to her brother, but Ritsuki assures her their sexual relationship is far from over and that they will have more rounds.
