My childhood friend, who is nervous about her first overnight date with her boyfriend, came to my room to watch an adult video to prepare for the night! While watching, she said she wanted to practice, even if it was just air sex! As she rubbed her crotch against mine through her panties... she got so wet that she stained her panties and got horny! When she took off her panties and started practicing, her dick, which was slippery with pre-cum, finally inserted itself raw into her juicy pussy! It felt so good that I had to cum inside her! She kept asking for more, so I couldn't help but go for a second round!
