UD-698R - My girlfriend's sister keeps seducing me while she's away

1st: Ichika Kamihata It was a bit underwhelming, but it follows the pattern of being assaulted by her sister's horny boyfriend. Usually, she's the one doing the seducing and NTR-ing, but this time she's the one getting taken. 2nd: Mio Kayama She goes all out with the NTR seduction. She acts like a nympho, making her frustration clear. Her sister comes home midway, but she lures her into the bathroom and they have a proper session. 3rd: Miho Tsuno She's having phone sex with her boyfriend over a video call... her sister's boyfriend, who was watching, gets turned on and starts messing with her without letting the guy on the phone know. Since she's already in the middle of phone sex, moaning and getting off is fair game. She gets completely taken advantage of, reacting sensitively and feeling it for real, eventually finishing with manual stimulation. Then they go straight into H. Changing positions while adjusting the phone angle to keep the real-life H hidden from the caller... that part is genuinely exciting.
