So, a couple went to see a sex therapist.
They ask the therapist if its ok if they have sex in front of him on his couch.
Intrigued the therapist says "ok" and watches them go at it for the half hour they paid for.
The next week the couple shows up again and does the same thing having sex on the couch in front of the therapist. Once the 30 minutes is up they say thanks and leave.
The third time the coulpe show up for thier "therapy" session the therapist asks them " Why is the only thing you want to do in my therapy session is have sex, i dont think you need sex therapy"
The couple says to the therapist:
Oh were not married to each other, we are having an affair. Instead of paying $60 on a hotel room we figured we would save some money by paying our $5 copay each and get a quiet room where nobody would bother us, have a nice soft couch, and a good alibis on were we are at.
