IENFH-32203 我那漂亮的妹妹心疼我，就帮我手淫，说好只是揉揉而已，但我们俩都爽得不行，我的小穴都湿透了！然后她直接没套套就插了进去！“什么？！进去了？”但我已经停不下来了，就在她里面高潮了

The unattractive man gets excited by her defenseless appearance! Even though he knows it’s wrong, he can’t help it and masturbates to his sister’s desire.

I’ll help you get it out,” she says, giving him a handjob and a blowjob, but he can’t get it off so she says, “I can’t put it in, but I’ll just rub it!”
