New muscle goddess

I called Sarah in my room "Yes mom?" "I want to see your resu..." As I turned around I was stunned she was almoust as big as I was, bigger than John clearly. "Wow you are really big" "Thanks to you and dad" "Well we tried but we didn't think it woud be this fast. Can you flex?" She put on a double bicep pose "Really good, sidechest" She did well too. "You are quite good" "But mom you are stronger" I grabbed her arms "I think you should show your dad" "But how I win him over?" I smiled at her "That's easy oh I almost forgot you are still a virgin, your muscle goddess body made me forget that. I guess before you go that round I should teach you?" "What mom?" "Teach you how to use your muscle goddess body to seduce him" I guided her to bed and got strapon "I know this is not nearly as good as the real thing but it will work"

I layed down on bed Sarah got on top of me she is quite big bigger than John but that's really good John likes it that way. I put it inside her "aahhh" "Now Sarah pretend that I am John. Get closer" Her pecs touching mine "That's good" I started to feel her back "Fuck me as you would him. Aaaahh slow down that's better. Look at me Sarah, your dad likes it when I stare at him so you should do it too" Damn she is gifted at this John is going to love her.

We did this everyday I also teached her how to turn John on. I got to see my own girl go from shy to really confident and seductive woman.
