Hey! Big brother! I can't do it with anyone but you… No way. Wh-what's wrong with her?! Until recently, she was such a sweet and clingy little sister, but one day, she started looking at me with those big, round eyes and sweetly, erotically scolding me... It was too much. She might be going through puberty...! She happily licked my nipples, sucked my dick with a blissful face, then straddled me and moved her hips on her own, even begging for more after I came. I've fallen even more in love with my little sister!
