Ok, so my girlfriends cousin went out of town and left my girlfriend and I to house sit her house. To be clear the cousin is a well looking girl in her mid 20's and has nice big breasts. That said she left us to take care of her house.
On our second night I was feeling horny and had a hard on and my girlfriend didn't want to do anything so we sat watching tv. It was around midnight and my girlfriend was asleep already so I went to the bathroom to take a piss. I have the tendancy to lock the bathroom door just because.
So I took my piss and the bathroom closet door was slightly open so I opened it and saw a pink thong. I picked it up and looked at it. I felt my dick get hard. I took a sniff and I was so horny. I sat on the toilet and started to jerk off and smell them... I was just way too curious and licked the crotch area and put it in my mouth and I kept on stroking and I came so hard it was all over my dick.
I used the panties to clean up and put them back on the dirty clothes... by the way I think those were the last pair of panties she was using before she left cuz they smelled nice..
