This is a 2 part movie! Here is part 1! You and your sister are naked laying in bed, like you always are when nobody else is home...you talk for a bit about being siblings who fuck and get to experience each other in every way, your sister ask if you've talked to mom and if you know when she's getting home... neither of you know but you want each other so bad the risk is worth it. Mutual masturbation leads to sex then watching your sister get on her knees and look up at you while you cover her body and mouth in hot sticky cum.... mom comes home and wonders where you both are only to find her son daughter half naked in the same room... she calls for a family then tells her daughter she needs to speak with her son alone. She wants to know why he didn't come to mommy with his family friendly urges... mommy grabs a basket full of sex toys and outfits and tries them on teasing her son over and over... real domme mommy... one thing leads to another and they fuck over and over until he cums... she calls another family meeting and lets us know she was too quick to judge us... sharing is caring in this family and this will be the new normal... to be continued...
