You like to fuck your sister because it helps distract you from wanting to fuck your Mom. Your sister lets you take your frustration out on her and even fantasises WITH you whilst having sex, about what you’d do to your mom if you could.. but your Sister is possessive and is jealous that who you REALLY want, would never.. COULD never want you back. Mom just isn’t the type of woman to have sex with her own son, or even understand the fascination you have with all things taboo. Your sister is so desperate to keep you interested in her that she offers you to have sex with her in both holes without protection for the first time, in the secret hopes that you’ll get her pregnant and then you’ll have no choice but to stay with her forever.. but although you agree, you still ask her to role-play as your mom for a while just to keep the fantasy alive. She reluctantly agrees and as you fuck her tight pussy and even tighter asshole all you can think about is how you’d much rather be fucking your mom.. mommy’s forbidden pussy.. the woman who brought you into this world.. your sister is just a toy to keep your cock busy until you find the courage to tell your mom how you really feel.. but the following day, your mom confronts you about what she heard last night.. what she KEEPS hearing.. sounds of a sexual nature coming from your sisters bedroom almost every night.. whispers of mommy role-play between the sheets.. her son fucking her daughter in secret.. reading your sisters diary and to her horror discovering that you’ve been making your sister play your mommy whilst you “do it”.. your mom makes it clear that it will never happen.. that is until she SEES the size of your erection pressing against your pants and can hardly hold back.. “no wonder your sister squeals” she says..
