被宠坏的继母交换他们的青少年继女

You girls are hiding from us. It's our responsibility to make sure that you girls are educated and that you're doing what you're supposed to be doing.

I think we're old enough to know what we're doing.

Old enough to know what you're doing? You're about to fucking have sex on your grandmother's quilt that she made me.

Old enough to know what you're doing? You can't even be responsible for yourself.

How are we supposed to know what we're doing if we don't experiment with each other?
