HUNTC-492 "Do you want to have sex with me that badly?" "I don't mind." "Please wear a condom." "I'm looking at my phone, so if you want to put it in, go ahead." My new stepsister is a bespectacled, introverted girl who'll have sex with me as long as I use a condom. But if I insert it without a condom, she'll arch her back in pleasure...

My sister-in-law is usually a quiet girl, and honestly, it's impossible to tell what she's thinking. She's what you'd call an introverted girl. But she has a sexy aura about her, so I honestly looked at her with lustful eyes every day. Then one day she asked me, "Do you want to have sex with me that much?" "I don't mind," "Please wear a condom," "I'm looking at my phone, so if you want to put it in, go ahead and do it," giving me a businesslike invitation to have sex. If she's going to let me put it in, I'll accept any conditions like that! And then came the long-awaited insertion... and of course, she was looking at her phone... What's more, her reaction was minimal... In fact, she didn't react at all! But when I secretly took off the condom and went in raw... my sister-in-law, who had been unresponsive until then, started moaning like crazy and arching her back as she came! The huge contrast excited me even more, and my hips started moving more violently! And my sister-in-law came again and again. She acts cool, but inside she's a super slutty girl.
