"Great! I am so pleased you both agreed to my proposal. You can trust me, Erik is our best assistant we have for this task," Dr. Wood said, contented.
"Yes. You've proven that we can trust you, Dr. Wood. And we really appreciate your help and support," Paul said.
"Thank you, Paul. Do not forget this is the best way to help your wife in winning a medal." Dr. Wood said with smile. Then Dr. Wood looked at Susan and added, "Sweetie, just relax. This is a natural continuation of your sperm therapy which has helped you to release all that restrictive tension in your body." The whole time Dr. Wood ran her hands gently across Susan's hot sizzling body, from her big succulent tits with their erect nipples to her wet swollen meaty delicious pussy.
Meanwhile, Dr. Clark left the office and a few minutes later, he returned with Erik.
"This is your new stud, Mrs. Fisher," Dr. Wood said officially, but softly.
"Oh, wow," was all Susan could manage to say while she was still lying naked on the bed.
"Do you like him?" Dr. Wood asked teasingly.
"Err... he looks beautiful... and so sexy!" Susan answered looking at Erik from head to toe, squeezing Dr. Wood's hand, expressing how much Eric excited her. Obviously Susan was fascinated with Erik's look and his sensuous youthful body. Like Jim and Tom had, he was also wearing a pair of tight white cotton briefs and nothing else. The bulge in his briefs was huge, Susan glared openly at it, her own eyes growing wet with desire.
"His cock is so big!" Susan added nervously, looking up at Dr. Wood's face.
"Yes my little hottie, your stud has a nice and big cock, exactly what you need," Dr. Wood said proudly and continued, "It's normal to be nervous for first time. Most wives are. Don't worry, when you feel that lovely big cock push up into you, all your reservations will disappear."
Susan nodded her understanding.
"What about you, Erik. Do you like Mrs. Fisher?" Dr. Wood asked.
"Yes, Mrs. Fisher is absolutely stunning! Her body is awesome," Erik stated honestly. His eyes drank in the sight of Susan's naked body, who to Eric looked like a younger version of his hot mother Kate. Susan was curvy and slender, her body was nice and firm with big, full tits. Erik loved her tits with their big dark brown areolas and beautiful pink nipples, her long muscular legs and her gorgeous face with those full lips, even her facial features were similar to his mother.
"I am very pleased you like each other. It is very important and this guarantees that your sperm therapy will be successful, Susan!" Dr. Wood said.
"What about you, Paul? Do you like your wife's young stud?" Dr. Clark asked provocatively.
"Err.. yes... Erik is a very fine looking young man," Paul replied nervously. He was absolutely floored by Erik's size and added worriedly, "But, his cock is so much bigger than mine. I am worried it will not all fit inside my wife's vagina."
"Yes, he is easily double your length and over twice your girth. But don't worry Paul, he will make room. And I hope your wife will be fully satisfied," Dr. Wood said and added with a smile, "I am sure you would be satisfied also." She knew very well Susan is going to be opened up wider and deeper than she has ever been after Eric is done with her. And if Paul would slipped into her again. Susan will not be able to even feel him!
Then Dr. Wood looked at Erik and said, "Erik, to help you understand completely Mrs. Fisher's diagnosis, let me tell you about it, but first, please come, lay down next to Mrs. Fisher."
Erik obediently climbed onto the bed nestling into Susan's soft warm body, so soft she felt as he touched her for the very first time, she could feel his semi-hard cock pressing into her hips. The feeling was amazing and her body responded immediately, with sharp electric currents sizzling through her loins each time he stroked his hand along the length of her left thigh. With a glazed over happy trance like look on her pretty face, Susan turned her head towards Erik giving him a little wet kiss. Then Erik kissed her, his lips sliding over hers in slow gentle movements, his hand was caressing Susan softly, slowly snaking upwards to her large tits. His fingers touched the underside of her tits and rested there as if waiting for permission to continue. Susan's hips begun swaying, her movements obviously becoming more involuntary. Dr. Wood was pleased when she saw that Susan's whole body was melting and relaxing in anticipation.
"Oh my god, she is so soft and hot," Erik said softly. He could smell her sweet delicious musky scent.
"Yes Erik, you are right, Mrs. Fisher is the really hot wife of Paul Fisher. She is also a great pole vaulter and in five days she has a major competition, the most important one of her career. Her problem is that she feels heavy in her body during these competitions. o help release this heaviness and tension she feels, we prescribed special therapy for her. We recommended her to have more orgasms and sperm in her body. So far, Mrs. Fisher has orally received large amounts of sperm from our young studs. This gave excellent results and now she is ready for the next phase, to receive sperm deep in her vagina," Dr. Wood deliberately delayed finishing her explanation.
Erik nodded, eyeing Susan's hot shapely body. Although Dr. Wood had already explained to him Mrs. Fisher's case, he enjoyed the re-explanation. Susan felt his cock growing with every passing minute.
"Erik, you must know that Mrs. Fisher is a naturally beautiful woman with a highly developed sexuality. Her sexual experiences also started relatively late when she married Paul. Also, she has a much higher sex drive than most women. I can say she is a highly libidinous woman like your moth... err... your teacher Kate, but she is inexperienced with men and with sex. But, I am sure Mrs. Fisher will quickly learn from you," Dr. Wood added.
"I understand," Erik said and nodded again. Listening Dr. Wood was so excited for him.
"Great, Erik! Once again, it is very important you understand Mrs. Fisher's needs and the fact that Mrs. Fisher is a healthy young woman with a REALLY HIGH sex drive. Mrs. Fisher is a little shy, but like your teacher Kate, she's the kind of woman that likes to fuck a lot when she gets relaxed. This means that Mrs. Fisher needs a lot of cock to keep her satisfied. So I expect your full engagement and that you apply all of the skills your teacher Kate pasted on to you," Dr. Wood concluded.
"You can count on me, Dr. Wood," Erik said with confidence. Then he looked at Paul and asked, "What about you Mr. Fisher?"
"You may call him Paul or just hubby. He is an open-minded person, and he absolutely understands Mrs. Fisher's needs. And he likes to show off his hot wife," Dr. Clark explained.
"Will he be present to watch?" Erik asked.
"Yes, Paul is very small and he wants to watch his hot young wife fuck a bigger and better guy. I think it's very natural for him to do so," Dr. Clark answered.
