"Would you describe this as pleasurable?"
If you are willing to
- completely ignore the existence of the medical ethics of a doctor-patient relationship,
- not mind at all that Theo, the patient, is totally cheating on his wife,
- overlook the lack of condoms and safe sex, and
- deal with some colorful wording such as "pussy-hole", "ass-pussy" or "man-pussy",
and just accept this PWP for what is, namely a storyline taken right out of a gay porn video, then you might actually enjoy this. I know I did.
There are worse ways to spend 20 minutes of your time, and there's definitely worse erotica out there.
