My father thought my mother was helping me review my homework. He didn't know that my hand was touching my soft belly from my mother's smooth thighs, and then he leaned into my mother's white short-sleeved clothes to hold the pair of plump and elastic breasts, and kept kneading them. In order to facilitate the wear, we didn't take off our tops. My mother only took off her underwear and bra, and lifted her waist with her skirt.
