She should end with her leaving and saying " Thanks , Dad"
Think that would blow his mind?
Is it just my imagination or have you started using slightly larger penises in your caps?
Not really. I have started using a few different ones that better represent reality (position, lighting, etc.). A while back, I started using a few modified versions of the same penis (Bailey Jay's). Mostly, I just shortened (because she's usually at least semi-hard), which gives the impression that its' a little thicker.
