Have you ever heard the rumor that "small breasts are more sensitive than large breasts"? This time, we at the SOD Research Institute thoroughly investigate this rumor. Small, petite breasts are kneaded, rubbed, and made to climax... A lot of ahegao faces of girls with small breasts are recorded. In any case, we have research results that we would like all those who like girls with small breasts to see! ! Enjoy! !
