After checking his hearing, eyes, heart, lungs, and skin Dr. Jenkins had Rex stand in front of him and take down his shorts. Being only eighteen, Rex was embarrassed to have to expose himself in front of the Doctor, but what really made him red was having nurse Boyd in the room. She seemed totally oblivious to what was going on, so Rex stood up and dropped his boxers to the floor. Doctor Jenkins rolled over in front of him on his stool and took Rex's testicles in his hand and told his to cough, but it was at this point in the exam when Rex's memory gets a little hazy, for at that moment Dr. Jenkins told Rex he had to check his sexual response, and before he could even ask what that meant, the Doctor leaned over and put Rex's cock in his mouth and started to suck him off!!! Totally stunned, Rex just stood there gaping as Doctor Jenkins sucked him to a full erection. Rex looked over to see what Miss Boyd was doing and was shocked again to see that she had her hand up her dress and was furiously fingering her hot pussy!
