Girlfriend Likes Pleasuring Me With Her Friends Panties

My girlfriend is so kinky and she likes me doing things with not only her panties but with her friends panties, wearing them, sniffing them, licking them, having her stroke me with either her panties or her friends panties. She really gets off when she can get a pair of her friends panties and bring them home and she can stroke me with them or wrap them around my dick and suck on me while her friends panties are wrapped around my shaft. I love it and it makes me explode so hard. She also enjoys when I wear her panties or her friends panties while we have sex, I love having a girlfriend who is so kinky and keeps sex exciting and  interesting. She will also sniff her panties panties and lick them, her favorite is to wrap them around my shaft and suck on me so she can smell her friend as she sucks me, she gets so dripping wet when we do this.
