This VR work, depicting the events of the day I was first invited to my girlfriend's house after dating my junior from work for three months, explodes with the devilish charm of her younger sister, Miyu-chan. The development where Miyu-chan, initially perceived as a 'good girl who cares for her sister,' gradually closes the distance is masterful. Especially the scene where you're tempted by her whispering voice makes your heart race. The actress's charm is in full display, and the setting enhances the immersion unique to VR. From the stealthy fellatio while cooking to the SEX next to her sleeping sister, you can fully enjoy Miyu-chan's cuteness without any waste in 77 minutes. Her skillful kissing and the technique to make VR look erotic shine. The quality of play is high, with plenty of highlights such as the eye-contact in the facing seated position and the sweet normal position, making it a supreme piece full of moments to enjoy.
