During summer vacation, my sister takes a nap on the veranda every day wearing hot pants that give a glimpse of her pussy. I can't resist my sister's slit, so I secretly fuck her every day so she won't notice. My sister's fair-skinned, plump, big-breasted body is moist with sweat. My sister's pussy has become so sensitive that the dick I put in her pussy during summer vacation fits her unconsciously and she cums just by being put in.
