Helen is the older sister. She has G-cup naturals. Erin is the younger sister. She has H-cup naturals. Together,they're the most boob-slapping,nipple-sucking,tit-swinging sisters in the history of big boobs,and believe it or not,in this movie,they oil each other's tits,give each other lap dances and buzz their pussies with vibrators side-by-side,too. Six scenes,two in which they do the kinds of things with each other that average sisters usually don't do,plus an interview.
