I met my girlfriend's older sister when I visited her house. By chance, one day I caught her in the act of masturbating, and after that, our relationship turned into something forbidden. Gradually, our bond deepened until we eventually had sex. The older sister keeps seducing me with dirty talk like "Impregnate me" and "Fill my pussy deep with your thick cum." She's more beautiful and sexier than my girlfriend. Is there any chance I could resist her temptation...!?
