285ENDX-444 — Kanami

Kanami, the older sister, a 24-year-old office worker, and Hiroshi, the younger brother, a 22-year-old college student, are close siblings who compete in a game of rock-paper-scissors, which is embarrassing and confusing, with a prize for money. If they get excited and get an erection, they get a penalty! What will be the outcome for the cute older sister and her cosplaying virgin otaku brother? It's impossible for siblings to get excited together, whether it's rock-paper-scissors or anything else! They take on the challenge with confidence! The older sister keeps losing, and finally she's in a very erotic outfit with no panties, no bra, and just a blouse! Her nipples are visible through her pants, and she gets excited! When she notices his fully erect dick, which is clearly visible even through his pants, she grabs it tightly and angrily strokes it, saying, "Hey, what's this?! Get flaccid, hurry up!" This has the opposite effect, and the younger brother's dick gets even harder and harder! The image of the sister lecturing her brother while playing with his dick because she might not get the prize money is very surreal. The brother hits him with a vibrator as a punishment game! The sister, half angry and shaking, endures the pleasure, standing with her legs wide apart and squirting. She is super embarrassed and stressed out. The excited sister seems to have won out over embarrassment, and starts handjob her brother's dick while laughing, and while grinning at his stiff dick, she suddenly says, "It's surprisingly big, isn't it... can I lick it a little?", which breaks the wall between sister and brother, and her brother is shocked. He resists in confusion, but he just sucks it as he is, and he faints in agony from his sister's excellent blowjob technique, but he doesn't cum easily, so the sister, who is impatient, says with a cute smile, "Well, shall I put it in?" and straddles her brother in a cowgirl position! She moves her hips in a comfortable manner, giving instructions such as "Touch my boobs more!", enjoying her brother's raw dick and cumming like a full-on bitch! This time, the older sister puts her hands on the wall and sticks out her ass, demanding a standing doggy style. The younger brother inserts his penis into his mother and thrusts it in and out, but it's like a moving dildo, and he screams and cums. When he is about to ejaculate, she urges him to ejaculate, saying, "It's okay, let it out!" and shakes her hips violently, and receives his sperm in her uterus and climaxes. Even though he has been creampied, she smiles and says, "It's still big!" while giving him a handjob like a little devil, saying, "Does that mean I can still do it?" and opens her legs wide to invite her younger brother's penis. When he is penetrated in the missionary position, she says, "It's really deep!" with a cute, troubled face, and feels it so much that she kneads her clit and has multiple orgasms! The younger brother is so excited by the gap between his sister's cute appearance and her slutty behavior that is the exact opposite, and when he is about to ejaculate again, she smiles and says, "It's okay, let it out!" and ejaculates for the second time! The semen overflowing from the convulsing pussy is filthy. When the brother and sister go to take a shower together, she sees the dick that's still erect and asks with a lewd smile, "Is it still not going down?", and while putting a vibrator against her pussy, she gives the dick a quick handjob, even squirting in the middle, resulting in a happy third ejaculation!
