Who Cums on their Sleeping Sister?

I loved sneaking in sisters room when I was young and discovered that I can bust a nut so my sis would sleep in panties and on stomach with ass up in air she was 13 and I was 15 and soon as I seen that my dick got so hard it turned purple so naturally I crept close enough I could feel the heat of her body on my cock and no more than I rested my hard dick in-between the buns of her ass checks I exploded and exploded I didn't think I was going to stop cumming and I don't see how she didn't wake cuz her ass was covered with her brothers fresh young loads of hot cum and from that point on I was a regular visitor to her room evernight sometimes 2 or 3 timese
