Dr. Linda motioned to Jimmy. “We need to prep you.” She hooked up a bl**d pressure cuff onto his arm, wrapping it tightly. She wheeled a machine over and connected several electrodes over Jimmy’s chest and back. She checked the machine and clicked several buttons. Lines and numbers ran across the various monitors. “There, we’re good to go. Jimmy, are you ready to start now?” He swallowed. “About as ready as I’ll ever be, I-I guess.” His testicles hung low. There was little hair, although she noted a clump of whisps that were thicker and more widespread than it appeared at first glance. She watched as Dr. Linda massaged her son’s balls, as if checking for something, but Diane wondered if she lingered there longer than necessary. Jimmy’s face was remarkably calm as he stared ahead, as if in a dream world. She felt the heat between her legs rising up into her stomach. This was too much. Dr. Linda bent Jimmy over very gently while simultaneously pushing him forward ever so carefully. “That’s right, just climb right up there, lay on top of your mother, just like that…very good Jimmy! See, everything is fine. There was no reason to worry. I think you’re going to enjoy this.” Dr. Linda leaned forward herself and snaked her hand between Jimmy’s legs. She gently handled Jimmy’s four incher and delicately tugged it towards his mother’s now sopping pussy. She looked down at Diane and met her eyes and then rubbed Jimmy’s cock head up and down the length of her exposed womanhood. She put her left hand on Jimmy’s bare ass and gingerly pushed him forward, surrounding his whole penis with the insides of his mother. Linda looked over at Diane again and saw a face of mixed emotions. Diane spoke to her son, trying to guide him in this new, unknown experience. “OK honey, now just raise yourself up…no, use your hips…yes, just like that…now go back in, there we go, you’re getting the hang of it.” Jimmy did as he was instructed. He didn’t like not knowing what to do in front of these two older women but he wanted to show them that he could learn quickly and that he was more mature than they thought. “Like this mom?” he panted in between breaths as he pivoted his hips into her’s. “Yeah…sweetie…just like that.” Jimmy noticed a different tone in his mother’s voice. Every now and then he would meet her eyes. They were starting to get watery now. “How does it feel, sweetie?” Diane asked her boy. Jimmy tilted his head to speak. “Mom, you feel really good. I’ve…never felt anything like this before…” Dr. Linda took out a small plastic cup and spoke. “OK Jimmy, just continue this motion you’re doing and remember, when you have to ejaculate you must pull out and try to push out as much semen into this cup as you can…OK Jimmy? This is very important.” Jimmy lurched forward again, cradling his head between his mother’s clothed breasts as his sensitive member was deeply inside a place no son should ever be. “I got it, Linda,” he rasped. An obscene, wet slapping sound filled the small office. Its source was unmistakable. The good Doctor looked down upon the scene and noticed Diane was breathing more heavily than her virgin son. “Are you OK Mom?” she spoke in a suggestive tone and with a sideways smile. “Yeah, I’m fine Doctor…how much longer until you have your tests done?” Diane was starting to break a sweat on her forehead. “Well, little Jimmy here is pretty young. Just a few more minutes and we’ll be good to go, I’m sure.” Diane was beginning to feel guilty about how much she was enjoying this. She knew she was a squirter if her orgasm was electric enough. It would be impossible for her to cover it up because her cum would start spewing out all over her son and all over the examination table. She felt like she needed Jimmy to cum first at all costs. It was one thing to strip away the barriers between mother and son and make love with her own c***d but it was a whole new level of embarrassment to reveal how much she was enjoying it to the world. “Jimmy, sweetie, could you maybe speed it up a little bit? Dr. Linda needs to complete her tests after all…” It sounded good to her at first but she shortly realized how detrimental this would be to her plan. Jimmy sped up his fucking and Diane hissed at the onslaught. The Doctor watched on, seeming to understand that Diane’s orgasm was just underneath the surface. Linda grinned and spoke again as she read the machine, “OK, his bl**d pressure is highly elevated. It looks like everything is within normal ranges for a person having sex. Diane’s view was twirling. It felt like she was falling. She grabbed the clumped paper underneath her with both fists as she craned her head back and stared into the bright lights embedded in the ceiling. It was too late. Her body could no longer hold off her true feelings. Her pussy started vibrating as an earth shattering orgasm rippled through her body. Her pussy started spewing cum onto Jimmy’s young cock and stomach. Her juices were splattering all over the floor and paper as her shapely hips bucked upwards. Dr. Linda had never seen this before and could only utter an “Oh my…” Diane started gasping as her jaw dropped as she moaned breathlessly. “I’m sorry honey, I’m sorry Dr. Hamsley!” Linda assured her, “That’s OK Mom, this makes the test even more worthwhile. It’s important that you keep up the rhythm Jimmy, make sure not to stop.” Jimmy was in a different world. His sensitive dick was balls deep in his own mother and her pussy was grabbing him tightly. He looked down and took in the sight of his sexy mother. He had never dreamed a feeling like this was possible. He felt something deep inside him twitch and become bothered. He knew he needed to say something. “Oooh Mom, I think I feel something…oh yeah Mom, I’m gonna cum! I’m gonna cum!” The young boy’s hips began to hump up against his mother’s even faster. Both were fucking into each other sloppily. Diane’s scared eyes met Linda’s. “Dr. Linda! Help me!” Linda was already working as she raced behind Diane’s son and hooked her arms around his waist to slow him down before it was too late. His hips were instinctively jutting forward. It was difficult to get control of him, as if he was a young bull. It was obvious the boy didn t want to pull out but she was able to slowly root out Jimmy’s slippery cock. She held the young boy in her grip, holding him just above his mother’s vulnerable pussy. He desperately wanted to go inside her one last time. Dr. Linda reached out to the counter for the plastic cup while gripping Jimmy’s pelvis. Diane couldn’t believe this was happening. She was still convulsing, her legs twitching deliciously as she rode her orgasm to completion and the lewd sight of her son’s purple, slimy dick made it all the more satisfying. Dr. Linda awkwardly grabbed Diane’s son’s young, glistening prick and pointed it near the edge of the plastic cup but he started spewing ropes of cum before she could quite steady it. His cum started flying through the air with no control. The first glob landed on his mother’s inner thigh, then several long, thick streams splashed right between her pussy lips. Linda finally managed to control his flexing dick and guided the last half of his load to the bottom of the cup. Dr. Linda’s gloved hand was stroking his member into the cup, trying to milk him to completion. As Jimmy’s orgasmic moaning subsided she pulled him off his mother. Dr. Linda spoke loudly as she went to a cabinet. “I’m so sorry Diane, we have to clean up his cum before some gets in you. Just stay in that position. Whatever you do don t move. Just relax.” She ran to the drawer and pulled out some spermicidal jelly. She sat in between Diane’s spread legs and, with a tissue, began sopping up Jimmy’s thick semen off of her pussy and pubes. Dr. Linda stretched her pussy lips with her left hand and went in deep with her finger to drag out the sperm that seeped in deeper. After she got the worst of it she spread the spermicidal jelly inside of her while Diane’s legs were shaking and her tummy was going up and down because of her panicked breathing. A few minutes later Dr. Linda got up and looked down at Diane. “OK, all cleaned up. That was an unexpected glitch in the program but no worries, none of it got inside you,” she lied. Diane responded happily, “Oh thank god Doctor! I really started worrying there for a little bit. You’re so good at what you do. I don’t know how to repay you.” She got up and started pulling her panties up her legs. She grabbed some tissues and walked over to Jimmy. With a wink and the flash of a smile she left the room like nothing had happened. Diane put on her skirt and adjusted her top. She helped Jimmy dress up. Neither one spoke. She felt the stickiness of where her son’s semen had been between her thighs. They hurried down the long corridor and headed toward the parking garage. Diane’s cheeks burned. It felt as if everyone knew what they had done. On the ride home half of Diane’s thoughts were on her son’s possible illness. The other half was her shame of how she couldn’t hold back her excitement during their fucking. Jimmy finally broke the silence. “Did I do something wrong, Mom?” Diane answered quickly, “No honey, you did great.” “I’m sorry I got my stuff on you.” “There’s nothing to be sorry about sweetie. That’s…well, that’s just what men do. You can’t help that.” There was an awkward silence that needed to be filled. He sheepishly answered, “It was fine…but, what was all that stuff that came out of your…you know.” “Well honey, that’s what happens to some women when she’s having sex and she enjoys it and she orgasms, just like you did today. You can’t help where it goes, right?” This piqued Jimmy’s curiosity. “How come I’ve never seen that happen in my movies? You just see the guy finish. Like I did.” Diane responded too quickly without thinking. “Because the girls in the porn are acting.” She realized what she said now. “So that means you enjoyed it, Mom?” “Well, that’s what I wanted to speak to you about. I told your dad about what we would be doing at the doctor’s so he knows all about this. I don’t think he will, but if he asks you don’t tell him anything that happened. Don’t tell him that I came. Don’t tell him I made a mess. Don’t tell him how long it took. Tell him it took just a minute or two. OK honey?” Jimmy was finally understanding what she was telling him. “OK Mom. No problem. I got your back.” He felt happy that his mother enjoyed it as much as he did. It made him feel less embarrassed. After they got home Diane cooked a nice dinner which everyone sat through in silence pretty much. Lisa barely ever talked at the table but even she felt like breaking the silence. “Everyone OK tonight? Why are you all so quiet.” Brian finally spoke. “I’m just a little tired honey, I’m going to bed.” Brian got up, walked over to his two k**s and kissed them each on the forehead. Soon after Lisa cleaned up the kitchen Diane went to bed herself. She tip toed into the bedroom hoping to avoid the conversation with her husband about what happened in Dr. Linda’s office but he was awake waiting for her. “He was a little bit nervous because at first he couldn’t get hard because the doctor was there, so then she left for a few minutes and then he was fine.” Her husband wasn’t satisfied. “What do you mean, he was fine?” She didn’t want to continue this conversation. He sounded jealous. “How can you ask me that question, you know Brian, I don’t really like your tone…” Brian felt she was right so he snuggled up to her and laid his chin on her shoulder. “I’m sorry honey, I was just a little bit worried. You’re right.” “Look, here’s what happened if you really want to know. He only lasted about a minute or two. And then he came into the cup which Dr. Hamsley used for testing. That’s all. It wasn’t even a big deal.” Brian laughed. “The little guy was quick huh? Yep that’s how I was at that age. OK honey, I’m sorry, I’m glad it all worked out for the best. Make sure to call me right away and tell me the results when you go there tomorrow, OK?” Diane turned around and kissed him on the lips “OK sweetie, good night.” The next day Diane got back home from dropping her k**s off and the telephone rang. It was a nurse from Dr. Hamsley’s office. “Hello Mrs. Adams, I’m just calling to confirm that you and your son have another appointment today at 2:30.” Diane was a little off put. “Yeah, it’s just for my son though.” The nurse corrected her, “No, I’m sorry but Dr. Hamsley was a little bit concerned about the test results and she says you guys need to come back and repeat your session again. I’m sorry for the inconvenience.” Diane spoke in a defeated tone. “No, no, I completely understand, thank you for notifying me and we’ll see you at 2:30 today.” She hung up. Her heart was racing. Do the nurses know that she fucked her own son? Is it in a file somewhere? She started to panic but eventually decided not to tell her husband. At 2 o’clock she picked Jimmy up from school early and took off toward the doctor’s office. “You have a good time at school honey?” she asked as she kissed him on the forehead. “Not bad, Mom.” They drove in silence for a while then Diane cleared her throat. “Honey, the doctor’s office called today and I’m sorry but we’re going to have to repeat our session today again.” Jimmy tried to not sound happy. “What do you mean Mom, what’s the problem?” “Mom, will you give me a blowjob?” he asked with no warning. Diane dropped her jaw in shock. “What? How dare you ask me that? Who taught you what a blowjob is?” “I’ve seen it in the porn, remember?” “Oh my god, you have to stop watching that. I mean it’s OK, but you’re looking at it too much It’s filling your head with crazy ideas.” She responded with half a smile. It wasn’t the porn. What she did the other day with him had awakened something in him. Jimmy wasn’t giving up. “Aww, why are you avoiding the NookieStar presents Mom?” Diane didn’t know what to think. She was a little bit disappointed in herself. She wondered how gullible she was for participating in these “tests.” Still, she thought that if she got him really horny and hard he won’t last as long as he did last time. This way she won’t have another orgasm in front of the doctor today. She kept on driving while turning these ideas over in her head. Jimmy asked again, “Come on, Mom, just this once, I’d really like to see what it’s like, all the guys in school talk about how great it is. It’s not that big of a deal for you after what we did yesterday, is it?” Diane glared at him in the mirror. “OK, fine. I don’t know why you want it so much. You know it won’t be as good as the other day, right? Anyway, you had better not tell your father, he’ll kill us both…you understand?” Jimmy was nearly jumping for joy against his seatbelt.
