You haven't been able to get off in months and decide to get checked out. You speak with a super busty nurse and after asking you a few questions she decides that you don't even need to see the doctor, she can already diagnose your problem without getting anybody else involved. She saw your wife in the waiting room when she called you back and thinks the problem is that your wife's tits are just too small to get you off anymore. Maybe a bigger pair of tits is all you need to finally get off again. Nurse Sarah jerks, sucks and titfucks nearly 20 loads of your backed-up cum and even lets you cum on her face while she insults your tiny-titted wife.
