I was at my friends house yesterday, we are close but not like best friends. I was more interested in his sister. She was hot, and 1 year younger. Anyways we were playing out in the pool. Then later his sister joined us. She didnt go in the water but she laid on the lounge beds. She looked amazing but i got an awkward boner. I had to jerk one out. I excused myself to the bathroom. I ran inside and went to the bathroom window facing the pool. I was jerking off then i realized that, no one was in the room atm. I snuck across the hall into his sisters bedroom. It was pretty clean. I instantly noticed the bundle of clothes on thw ground. She must have just taken those off. Inside her jean shorts, was a treasure. Her panty. It was a yellow g string. I took it out and it was still warm. They smelt heavenly. I didnt want to take too long so i hurried. I opened tr first drawer to find her panty drawer. I took 2 more . A lacy black thong, and a blue gstring. Then i saw her hamper and took 3 more from there. A pink thong, ghe same thong but blue, then a black gstring, and my favourite, these super small panties that was nothing more than a string a see through patch over her crotch. I hid these in my bag before returning.
