Your sister walks in on you sniffing her panties that you stole from her room. She calls you a pervert and is pissed until she realizes those aren't even her panties. You took the panties that your sister stole from her friend. Your sister was dancing and grinding on her friend the other night at the club and her pussy go so wet. Your sister wanted to see if her friend was getting wet too, so she stole her panties. Apparently, panty sniffing runs in the family. Those are the panties you were sniffing and as you could smell, she had gotten very wet. Your sister takes the panties back, and ties your arms up with her scarf. She stuffs her panties in her pussy and masturbates while sniffing her friends panties. All you can do is watch her as she rubs her pussy and degrades you. "Do you like sniffing all girls panties, or just your sisters." After she cums, she pulls her panties out of her pussy, shoves them in your mouth, and leaves, wearing her friends panties.
