Smelling My Girlfriends, Best Friends, Panties

My girlfriends best friend was staying at our place for a few days. I get so horny knowing that she can hear my girlfriend groan and moan as I fuck her at night. She's a virgin for sure and I knows she jills off because I got up one of those mornings for work and saw her masturbating. The first day she was here we were headed to an afternoon event that my girlfriend was already at and her friend needed a ride there. It was a bit windy and it caught her skirt and I caught a glimpse of her ass in her see through panties. Instant horny as fuck. Cock was throbbing. Acted as though I had seen nothing. The next morning my girlfriend had to go to work for a short bit. Her friend got up and showered and left. I went to the room she was staying in, found her dirty panties from the day before and took a big inhale of them. Her panties were so crusty and white from her dirty wet pussy. Must have heard us fucking and made her so horny. Sniffed them while I stroked my big hard cock to an explosive cum. Squirted some on her panties while the rest went all over the floor. Cleaned up my mess just in time for the girlfriend to come home. That morning I got up for work and I was really quiet moving through the house. Heard that familiar moaning and groaning coming from her friends room. I slowly opened the door a little and there she was ass in the air naked as fuck sniffing her panties I came in and fingering her pussy hard. Her pussy was sloshing wet and her pussy bald. Cock was so hard. Started stroking my cock while watching her jill off so rough. Came in my boxers quickly watching her fill her virgin wet pussy. Watched her finger fuck her pussy to an intense orgasm, her body shuddering, her pussy and fingers so wet. I shut the door, got ready for work and left. Got home from work no one was home. They were out for a few hours shopping and seeing old friends. I found her real dirty pair of panties from the day before and rubbed my hard cock all over them. They were a lot dirtier than the other pair and her pussy juice was soaked right through and all down towards her ass. That huge white crusty stain made me so horny. Took a big sniff. So sweet and smelled amazing. Stroking my hard cock so good. Holding her dirty panties over my wet hard cock I squirted a big load into them. Fuck I was so horny I squirted so much in them. Cleaned them up a bit and put them back in the suitcase. Grabbed the other pair took a big whiff of them. Fuck I had to come again. Took no time and I squirted a big load in them too. Wiped it up the best I could and put them back. The next morning I had to work and I knew I wouldn't get a chance to see her again, so I snuck in her room grabbed her dirty panties and went to the bathroom and jerked off so quick and made a mess of her dirty panties again. Cleaned them up and put them back. A few days ago she messaged me on FB and told me she knew what I had done and that she will keep it our secret. Told me it was so fucking hot and dirty knowing that I smelled and came in her dirty panties. Told me she had the best orgasms smelling her panties that I came in, smelling my cum. Looking forward to the next time she visits.
