My Beloved Stepbrother -The Possessive Love of the Sadistic Marquis

"Punishment from my stepbrother... Instead of pain or pleasure, I'm happy." "No matter how much you resist, it's useless. Prepare yourself." "These red lips, this white skin, and these soft breasts, they're all mine," whispers her brother to the unconscious Alice. Alice and Gilbert became siblings when their parents remarried. Alice fell in love with her stepbrother the moment they met. Since then, she has been nurturing these feelings, knowing that it is forbidden for a brother and sister. One day, Alice hears a rumor that Gilbert, now a duke, might marry a princess, and she becomes deeply troubled. Deciding that she would rather have him than let him be taken by another woman, she tries to give Gilbert an aphrodisiac to initiate a relationship. But she accidentally consumes it herself! Her aching body is then thoroughly loved by her brother's fingers and tongue, and she loses her purity! (Source: BisouBisou Comics)
