My niece Kim has just turned 13 and one afternoon while I was waiting for my brother she came into the lounge and flopped onto the sofa next to me. My heart thumped as she had just come back from her cheerleading practice and had on a tight lycra shirt which showed off her ample chest and a cute tight pair of blue spandex shorts.
Moments later she grabbed the remote from me and threw some cushions on the floor before sprawling on them. As I sat there I had a perfect view of her cute tight bum, her thighs slightly apart allowing me a view of her mound bulging underneath. I could make out her panty lines and every now and then she would squeeze and flex her bum. I was throbbing at the sight and had to drop my newspaper on my lap when she sprang up and said it was time for her shower.
Being alone I squeezed my raging cock dreaming of her cute bum, moments later she padded out of the bathroom and slammed her door shut. I got up and headed for the loo deciding to deal with my boner, my heart almost burst when I saw her clothes on the floor of the bathroom.
Locking the door I dropped my jeans and picked up her shorts complete with her tiny blue panties still wrapped in them. Untangling them I held the shorts to my face and draped the panties over my cock and stroked the gusset over my throbbing member, moments later my legs buckled as I shot a wad into the warm cotton.
