In our family, I, Marisa, the eldest, have been acting as both sister and mother to my three younger brothers since we lost our parents at an early age. One day, the youngest, Dai, sulked after admitting he'd never experienced reverse anal before, causing quite a scene. Lately, my normally energetic brothers have been fighting over me, jealous of each other as they compete for attention toward my clit-dick. Today, my second brother found himself alone at home with me—and seized the chance to have me all to himself. The second son, blessed with the biggest cock among the three brothers, came to me with his aching ass craving attention. After I made him climax repeatedly through reverse anal, we faced each other, stroking off together before unloading massive amounts of cum in unison. Meanwhile, my cross-dressing eldest son, always the mischievous prankster, tried sneaking on my bra without permission. As punishment, I blindfolded him, which only sent him into greater excitement—we climaxed in each other's asses and filled one another with creampie after creampie. Back in the bedroom, the youngest Dai sulks again under the covers (laughs). But Dai, now stepping into manhood, is finally at the age to experience reverse anal. I gently massage his anus with my balls, slowly stretching him open with my fingers. Seizing the moment when he relaxes, I gradually push my clit-dick inside—achieving perfect penetration! As he grows accustomed to it, young Dai moans sweetly like a girl, utterly adorable. Despite it being his first time, he cums over and over, finally earning his place among his older brothers. That same day, he experiences anal creampie for the first time—and overwhelmed with excitement, his cock swells inside my ass as he thrusts upward violently from below! Thanks to him, my clit-dick stays rock-hard as I climax deep in my ass, marking the beginning of our family's endless cycle of incestuous gangbangs—penetrating and being penetrated, over and over again!
