Make changes

Rachel's ample chest was moving a lot more now as she breathed and Tom figured that the improvements were working. She didn't take much more time before she leaned forward and guided his cock into her moist hole, groaning lightly as she sat on the head and started working her way down it.

He let her finish sliding down and then after a few seconds of her lightly gyrating her hips he continued "Who is bigger Don or Me?"

Her face a little flush, Rachel answered "You are both about average"

With a few seconds, you increase your length and width a bit, nothing monster-sized. Just 20% bigger, You don't want to break Rachel.

Rachel gasps loudly as she feels you grow inside her. "Oh God.... you are a big boy!... How did I not feel that last time?..... Mmmmm you hiding anything else?"

Not sure what to add you, you slightly increase your overall size again, now 40% bigger. Once again provoking another reaction from Rachel.

"Oh fuck... oh fuck... I don't know how you did that but I hope you don't have too much more... That's the biggest cock I have ever had inside me!" she starts to gasp, her breasts heaving in front of your face. "I have only tried a dildo this size once before, I didn't know real cocks could get like this!"

Smirking, you lock your personal setting so you don't accidentally hit it and then reach up to play with those heaving large tits in your face. "I bet you will enjoy yourself more this time"

Still not over the feeling of you increasing your size while inside her she was still gasping. "Good thing I'm only having sex with you, for now, this will leave me too sore for anyone else." she groans. "I hope you are enjoying me, Tom, I really am sorry for what happened in the past"

"Oh I am and I know you are" He chuckles and bites at her nipples.

Rachel's slow gyrating had now changed to full-on bouncing on his now much larger cock. The living room was filled with the sounds of her ass slapping against his thighs and the moans and gasps of the married woman.
