Step daughters/Asexual/1st Wednesday/pleased Sandra/Masha Watches Sex/Calm/Give
You decide not to push it for now. What you did with Sandra already was a horrible risk, and Masha doesn't seem especially open to your advances. At least she hasn't connected you with the child porn up on screen right now, that can be passed off as a trick the internet played on her.
You sigh and settle in to watch as the boy, under the mother's encouragement, speeds up and eventually groans and begins pumping his young barely teenage load into his elementary school aged sister, and then pulls out as the camera angle manages to capture the white goo leaking out of her vagina. After the mother compliments the kids on what a good job they did, they begin to play with the leaking cum and smear it around on the girl's belly, and then the brother collapses on top of his sister and they cuddle for a while before the video ends and goes on to the next show Masha had lined up.
Masha seems to be stunned at the images she just saw and still doesn't know what to make of all of it. Meanwhile, you hear the activities of Sandra moving around in her room. It seems like she's snapped out of the euphoric state you left her in and now she comes barreling out of her room having gotten herself dressed again, looking just as happy and excited as ever as though nothing ever happened.
"Hey! You left when I fell asleep!" She says with an accusatory tone, not really mentioning the conditions in which she had her little temporary black-out. (she calls it sleep, but you really don't think you would considering how short it was.) But then, her eyes go and lock on to something else and she goes scrambling over to her older sister. "Hey Masha! Guess what!" She says with a giant grin that is giving you cold shivers down your spine. "He just licked me down there with his mouth! Isn't that gross!"
"Huh?" Masha responds, but her mind goes off somewhere else. Probably thinking to the part where the boy on the video was doing exactly that same thing to his sister.
"Yeah! And then it felt really... really... uhh... something! It was really weird and neat and made me scream and then... I think I fell asleep."
Ok, great. What to do with this?
