This was a few weeks ago and it was spring break.
Our neighbors were going out of town for the week and they gave us the keys to their house to take care of it. The neighbors have two daughters, one is in college, another is one year behind me is HS. They are both brunettes with blonde highlights and both have athletic bodies. The college girl has C cups and HS is a B but still growing.
Well anyway my mom is working in the office and the key to their house is in there, so I just slip in there and took it. I sneaked over and went in through their garage door and on to the upstairs bedrooms.
The college girl, who I will call Arin, her bedroom is straight ahead and HS girl room is to the left and I will call her Katlin. I went into Katlin's room and looked for her panty drawer and didn't find anything good, so I went into Arin's room and found the jackpot. She left a clutter on the floor but her closet was in better condition. On the shelf I found the container that had the panties. It was filled with a lot of g-strings and lacy panties. I got really hard in a second and couldn't stand it. I grabbed a handful which was a lot and took my pants off and started rubbing my cock. I laid down on her bed and started to pick out a few g-strings and started sniffing them deeply and rubbing the silky smooth ones over my cock and I was oozing pre-cum all over the bed and panties. I thought of her sweet wet pussy in the crotch patch on the thongs and licked them. I lasted only a couple of minutes and blew a huge load all over her bed and panties. I sat there continuing to rub and sniff, but I had to clean up and leave before my mom realized I left.
But before I left, I took a black, blue, pink g-string and a purple lacy thong back with me as keep sakes. I went back the next day and did it again but lasted a minute that time.
I don't believe she ever noticed I was there or that she is missing any panties.
