Step daughters/Asexual/1st Wednesday/Masha Watches Sex
You had secretly swapped out the next video on Masha's playlist for a carefully selected video of a 12 year old boy having sex with a beautiful 8 year old girl who looks every single bit as amazing as Masha, all with the help of what is probably the mother of both children. The video starts off with the woman having the kids both remove their pants, while she's remaining fully clothed. After this, she has her daughter spread her legs open for her son, and then she starts pointing to parts of her daughter's spread open slit and explaining how girls feel very good if you rub them in certain places, which she matches with a demonstration before prompting her son to repeat those actions.
There's a little bit of licking, and then the woman finally encourages her son to stick his penis in. You've walked in on the part where the licking is about to start, and are rather pleased to find Masha with her hand between her legs. She looks up to the screen just as the boy is going down on his sister.
"Eeew!" Masha says out loud.
"What-cha watching?" You ask, causing Masha to nearly jump out of her skin as she turns and looks at you in a state that seems like it's almost in fear.
"Umm..." Masha looks very quickly between the TV screen and you. "They're touching each other!" She says.
Well, she most certainly seems very worried about what she's seeing. You can think of a number of ways you can handle this.
