You can’t quite get your head around it, that time incest sex sort of happened. Your sister and you were playing as usual but this time you were going to copy what you saw mommy and daddy were doing. You both strip down, and are naked together.
So there you are sister and brother naked together. This is where I come in and I start guiding the two of you into the whole incest phone sex act. I direct you two to kiss and put your hands on each other and just feel all over. Go ahead stroke your brothers penis I tell the sister. And as she gently slides her hand up and down that stiffening shaft I got her to kneel down and put her lips on her brother penis and start sucking. Well, needless to say the session was over quickly after that! Next session we’ll have the brother lick his sisters pussy and maybe even some penetration.
