Let's see if I can figure out why your wife doesn't put a spring in your step, so to speak. Maybe she doesn't wear lingerie like what I have on under my lab coat. Maybe her boobs aren't as big as mine. You seem to respond to my methods. I'm gonna need to take a sample, now. Go ahead, strip down and lie on the bed. I am a hands-on doctor, so try to relax and enjoy the attention I will give to your swollen member.
