Dr. Cacherín

A renowned Boxer known as El Potro, arrives at the emergency room with his assistant and his Trainer at Dr. Cacherin's office. This boxer arrives with a swollen face, all purple, after having had a confrontation with another boxer. Dr. Cacherín, as usual, is clueless and believes that the trainer is the one who has to take care of him when he sees his face. The nurse tells him that the one who should be taken care of is not him, but the boxer in the red shorts.

Dr. Cacherin asks his nurse to check Potro to see what condition he was in. The nurse puts her ass on top of Potro's penis, and her huge tits on top of his face.

Potro says that if this treatment is working, he is already feeling improvement, and the nurse feels something difficult to grow.
Dr. Cacherín says for the treatment to work more, he must help the patient with the Nurse. This is how a delicious threesome comes out, fucking the nurse, Dr. Cacherín, together with El Potro.

a unique medical treatment in the world. In the end the Potro is as good as new ready for another confrontation.
