Dr. Blum's Dungeon Ch. 02

Jake's whole life was changed by Dr Blum. He'd begun to work for her under the table (both literally and figuratively), and even gave up his apartment to live in the basement of her office. As it turned out, Charlotte had a room down there too, and it became her life's work to terrorize him. Dr Blum allowed her free use of his body at all times, and she abused that privilege. While he enjoyed the exhaustingly frequent sex, she interpreted the rule beyond that. Whenever he let his guard down, whether it was turning a corner, filing papers in the office, or even sleeping, she would find ways to hurt him. Her acts of terror included sucker punching his face and balls, shoving things up his ass, biting his cock with the force of a shark, lashing him with a whip, slamming her ass onto his face, and on one occasion pissing right onto his face in his sleep. Without fail when Jake saw the smirk and cackle on the pretty face of this sexy but evil green haired monster, he'd go right to rage fucking her, which was probably her plan all along.

The good Doctor herself didn't go easy on him either. She dedicated very little time in her day to seeing actual patients, and instead would fill half of her work hours with riding Jake's unnaturally enlarged cock until his balls were drained and then smothering him with the mess. Then, she'd amuse herself with torture and the odd medical experiement, and on this day, she apparently had one that excited her. He entered her examination room at 11 AM, when he was penciled in for her schedule and wordlessly stripped off his scrubs. A pit grew in his throat and his balls clenched as he saw an operating table along with lights and equipment. Charlotte was standing submissively at attention behind Dr Blum to assist in the experiment.

Even with the daunting fear of what new hell he was in for, Jake couldn't help but get drawn into the doctor's beauty, with her breasts pushing the limits of her blouse and thick, porcelain thighs barely covered by her short skirt. Whatever today entailed, this incredible woman was worth it. Her lovely freckled face made an excited smile and from plump lips she spoke, "no need for that look, we've got something incredible planned for today. Lie down won't you?"

Jake did as he was told. By conditioning, and the sensitivity the serum gave him, his enormous cock already stood at full attention, awaiting commands. Dr Blum pulled two slicky white pads with little round pieces of plastic attached to them from her tools, and stuck them to his temples, then did the same for herself and Charlotte. Jake began to feel strange sensations throughout his body, including a warm wet tingle on his crotch.

"Fascinating," Dr Blum exclaimed. "So it's true. A colleague of mine overseas has made an incredible breakthrough. She has developed this device we're all experiencing now. What you're feeling is the physical sensations of both Charlotte and myself. Allow me to demonstrate." She then nodded to Charlotte who got to her knees and began to eat the doctor's pussy. Jake shuddered. He felt it, and it was amazing, yet strange. He felt the sensitive nerve endings of Dr Blum's clit explode at being licked, while also feeling the familiar act of eating her out. He understood why she loved this feeling so much, and felt a unique technique Charlotte was doing that he would be sure to try himself.

"Feel free to masturbate, just don't cum," the doctor told him. He obeyed, and it only intensified the sensation. He felt the simultaneous joys of jacking off and having a whole new genital stimulated. Dr Blum moaned louder than usual, as she grabbed Charlotte's green hair and pressed it into her mound forcefully. Over time he felt a hot churning inside of him as his pleasure built. He was approaching a dangerous point in his masturbation and removed his hand. However, the clitoral pleasure continued, and despite his best efforts, as he felt the symphony of Dr Blum's orgasm, with the utter release of squirting and being squirted on, a blast of cum erupted from him, landing on his chest.

POW. A powerful slam on his balls from a baton, and then hits against his cock that threatened to snap it in half. He looked down to his bruised and battered package and saw Charlotte whimpering in the fetal position. "Marvelous," Dr Blum said. "You see the magnificent thing about this device is that it works both ways, and is customizable. So for our purposes, all of your pleasurable sensations are mirrored in me, while Ms Charlotte here is receiving your painful sensations. How did you like that, dear Charlotte?"

Charlotte struggled to catch her breath. "It was horrible."

"Horrible? But that's how you've been treating our poor Jake day after day. How bad could it be? Here, give him your usual sadistic torture."

Charlotte approached hesitantly, then raised a shaking hand and slapped his balls. Even a little slap caused gut wrenching pain, especially on bruised and swollen balls.

"Why that's odd, I was under the impression you went much harder on him. Why, you wouldn't go easy just because there are consequences for you, would you? Tell me Jake, is she going easy?" He looked at Charlotte staring daggers at him, and thought of her sheer sadism these last few weeks.

"Yes, Doctor. She's usually much harsher," he admitted gleefully.

Dr Blum made a series of 'tisks' as she bent Charlotte over the table, ass up with her face pressed into Jake's dick and balls. Jake tried to swat away whatever was touching his face before he realized it was his own dick. Dr Blum grabbed something from her tools and then Jake felt electric pain burning sensitive nerve endings. She'd apparently grabbed a taser, and punished Charlotte's clit with it. The two of them convulsed and had the wind knocked out of them until the doctor pulled away.

"Now dear. Show me what you really do to him." Charlotte gritted her teeth, fighting tears, then slapped Jake across the face with all her might, then punched his balls without concern, letting out a groan of anguish. Then she bit the sensitive area under his head, and grinded her teeth on his foreskin, as a single tear fell down her face. Throughout this pain, Jake felt an oasis of pleasure, as Dr Blum squeezed her own plump breast and masturbated with a vibrator. This beautiful focal point gave Jake the strength to bear the torment.

Charlotte looked back to Dr Blum, hoping for relief, but got a sternly shaken head in response. Charlotte grabbed the nearby baton and shoved it up Jake's unlubed ass, screaming as she did. She twisted his nipples, drawing a drop of blood, and yanked the baton out of his ass and beat his cock and balls with it. Neither could continue anymore, and the two of them begged for mercy.

"Alright, I suppose you've had enough. Now usually when this happens, you take all that rage and you fuck Charlotte as hard as a bull right? With the state of your poor, beaten penis, would sex hurt?"

"Yes Doctor," Jake said, "but it's worth it. It hurts, and it feels good."

"Good. I get all the pleasure, she gets all the pain. It's time for your hard revenge sex." Charlotte gave a half smile, as she still always liked this part. "-on me. Fuck me like you fuck Charlotte. Fuck me with anger." Charlotte dropped her eyebrows and opened her mouth in disappointment.

Dr Blum stripped completely, then joined Jake on the table. She lied with her face down, arching her back and pointing her legendary ass straight up. She then began using her vibrator on her clit again, sending shocking waves of pleasure through Jake. Jake assumed position and mounted her like an animal. The first penetration was intense, on both ends. He couldn't tell where he ended and the beautiful Rachel Blum began. He began thrusting, with his sore cock enjoying the wet, hot pleasure of fucking this incomparable pussy and the new but enjoyable feeling of getting fucked by himself. There was pain coming from Doctor Blum's end too, with an overly filling, stretching sensation from getting railed by something too large, not to mention a shooting, stabbing pain whenever he bashed his head into her cervix. He now understood that part of what these two enjoyed about his dick was a masochistic pleasure from pain, along with a strange satisfying feeling from being filled to the absolute limit.

He continued relentlessly, animalistically. They came to their first orgasm, a shared, simultaneous firework show of complementary pleasures. Jake didn't slow down. He let his cum fill her and overflow and lubricate his way. Pretty quickly, a second one came, this time Dr Blum squirted and her knees buckled as he shot another hot load inside of her. She spasmed, as he felt on her end that it was overwhelming, and she squirmed away and pushed him back.

"Wow," she got out, catching her breath. It was unusual for her to lose her composure like this. "I could get used to that. Charlotte, dear, lie down and clean me up. Jake, fuck her as hard as you just fucked me."

They both did as they were told, Charlotte lied down with her legs in the air, and Dr Blum took a seat on her face. Jake made the first plunge into Charlotte's already wet pussy and went to town. This had a whole new dimension of intensity. All at once he felt sensations of eating the doctor's cum filled pussy, getting her pussy eaten, fucking Charlotte, and getting fucked as Charlotte, who apparently was extremely sensitive in there. She was tighter, and her cervix hurt more, but she'd apparently trained herself to enjoy that feeling a lot.

"Wow, dear. So fucking Charlotte feels completely different from fucking me. What wonderful... variety!" Dr Blum pulled one of Jake's hands to her ample tit, and he squeezed, enjoying both ends of the feeling. She then went in for a kiss, and they began passionately making out like enamored teenagers. This feeling, this strange love, was what it was all about. This got him up in the morning.

All three of them reached climax, a perfect harmony of orgasmic joy, and the feeling only stretched. Charlotte had reached her limit of oxygen deprivation, drawing out and intensifying the feeling. Jake felt a 'static', 'asleep' light-headedness, until... until...

Darkness.

Jake awoke on the floor, with a sore head. Dr Blum's beautiful face was in front of him and her auburn brown curls draped over her face. She had a look of concern he hadn't seen from her before. "Oh thank god, you're awake. I went a little overboard on Charlotte's breath play and she fell unconscious. She's more than used to it, but interestingly, it knocked you out too, and that's pretty dangerous when you're upright."

"Yeah sorry dude," Charlotte said, rubbing her head. She gave a smile, and looked into his eyes. He felt a sense of comradery between them now, maybe because they now knew how it felt to be each other. She offered him a hand to stand back up, and gave him a kiss when he was vertical.

"Well I think we can safely say this experiment was a success," Doctor Blum declared proudly. "Unfortunately I could only convince my colleague to let me try the devices for a week, it has to go back for years of testing. So let's make the most of it. We're keeping these on for the rest of the week. Charlotte, dear, you've been a trooper, so I'll set your receiver for Jake's full range of physical sensation, and mine too. I wanna make sure you're keeping up his training. Dial it down a little though, we'll all feel it and find the right middle ground so that he gets the torment a good subby should, but make sure it's not hard enough to erase any masochistic joy in it."

"Yes Doctor, thank you," Charlotte agreed.

"Now Jake, I believe your hazing phase is complete. You're both my subs, but the two of you now share an equal rank. That means you have free use of Charlotte just as much as she has of you. Train your sadistic side, torment her as much as she does you. She's been with me a long time, and she's used to it, so get creative."

Jake absorbed this new paradigm and accepted it. The wheels started turning in his head with ideas to get revenge on his cruel roommate. "Thank you Doctor. I won't let you down."

"Charlotte," Doctor Blum began. "Do you accept this? Will you submit to Jake, as you both submit to me? Will you allow him to use and abuse your body, as you do his?"

"Sure, fuck it. I can take whatever this pussy throws at me. Plus he's kind of cute," Charlotte said confidently.

"Splendid. Now clean up this mess, I have appointments."

Dr Blum kissed them both and tossed her clothes on, then left. Charlotte bent to grab her scrubs, and Jake took the opportunity to give her a hard slap on the ass that left a mark. Jake winced as he felt the slap himself. Charlotte just looked back and grinned, then teasingly said "amateur. Was that supposed to hurt?" Prompting another, harder slap in the same tender spot, which drew a delighted moan out of her, then an equally hard slap on the balls.

The two hurriedly wiped everything down and rushed downstairs to the basement. They fucked like rabbits. Jake tortured Charlottes nipples, pulling and twisting the studs pierced through them to the point of almost ripping, then letting go. Charlotte scratched his back to the point of bleeding. Jake jack hammered Charlotte's asshole, a pain he could barely bare with the sensors. That's when Charlotte got creative.

Charlotte realized she was much more tolerant to her own pain then the new kinds of pain she felt from Jake's body, so she took advantage of that. She waited right up to the moment when Jake was about to cum, then punched herself in the uterus as hard as she could causing a nauseating cramp. Jake fell backwards in pain, taking Charlotte with him, flat on his back but still inside her ass. She then started pinching her own clit between her nails and riding him like a mechanical bull. This sent Jake screaming.

Things went on like that for a couple days, all out war. Constantly one-upping each other with new ways to hurt each other and themselves. Then, on the third day, they were exhausted with it. Jake woke up with Charlotte in his bed, just cuddling. He held her, and she woke up.

"Ya know," Charlotte pondered aloud, "I've got the rare opportunity to feel what a guy feels and I'm wasting on feeling how a guy hurts. This whole time I haven't bothered to see what it's like to get your dick sucked." She then worked her way down to his morning wood and gave it a gentle kiss. Then she took it into her mouth. Feeling his own dick in his mouth wasn't nearly as good as getting it sucked, but Jake let her have this.

Charlotte sucked tenderly, taking it deeper and deeper, occasionally taking it out and jacking it off, then began to suck with more fervor, taking the whole substantial thing down her throat for extended periods, and licking the head on the way out. She cradled his balls, gently, then slowly put a wetted finger up his ass, and began rubbing his prostate. It didn't take long before he shot a big load of cum right down her throat.

"Not bad," Charlotte declared, before claiming onto him and guiding his dick into her. She moaned softly, and Jake kissed her neck, and then kissed her ear, and breathed into it. She reached backwards and gently held his balls as she kissed him. They fucked gently, enjoying each other's bodies. In the end, Jake sucked Charlotte's nipples as he gave her a creampie. He stayed soaking inside her as they lied there, embracing each other.

"Shame I didn't get a turn," Dr Blum pouted, now standing in the doorway. "Pity. We best get this thing on you as soon as possible though. I have something very special planned for our last day with these devices, and I'll need you to save up as much of that precious seed as possible." From behind her back she pulled a large, banana shaped, metal cage. "I know, none of us are going to like this, trust me, but it's probably a one-time measure."

Charlotte groaned and removed herself from Jake. Dr Blum cleared the distance and Jake felt an uncomfortable cold sensation and at once his dick was wrapped in this strange metal contraption. "As it turns out, they don't make chastity cages for penises that are larger than most erections whilst flaccid, so I had to get it custom ordered. Still a tight fit though, apparently." She then inserted a strange curved sounding rod that screwed into the top, then locked the whole thing. "This rod will not be allowed out except in cases of urination, if you have to pee we'll all feel it and one of us will come to remove the rod." She then pulled a syringe from her lab coat and gave each testicle a stab. "This will kick sperm production into overdrive. They'll be extremely sore, but take comfort in knowing that we're all suffering with you." She then capped it off with a kiss on the balls.

"Why though? It's such a waste of fun," Charlotte protested.

Dr Blum swiftly slapped Charlotte across the face, then kissed the tender cheek. "You'll see. It'll all be worth it."

...

The next few days were a unique torture. Horribly aching balls, and his dick trying to get hard but being suffocated by the cage. It would be a lot easier if he wasn't feeling orgasms constantly. Charlotte walked around with ben wa balls all the time now, jiggling and vibrating inside her, and Dr Blum almost never took a break from her vibrator. That's not even to mention how much they ate each other out, or made Jake eat them out. Dr Blum even teased Jake by sucking his balls and massaging his prostate, but every time his body tried to cum it was blocked by the sounding rod and backed up into his bladder, giving him a horrible, sick feeling.

By the time the ordeal was over all three of them were limping around irritable and uncomfortable. Finally, the last night arrived, and Dr Blum couldn't conceal her excitement. They finished up work in her office, and the doctor handed Jake a small paper cup containing a few pills.

Jake downed the pills with some water. Then, he asked, "so what did I just take?"

"Oh just a cocktail of stimulants," Dr Blum replied nonchalantly. "Mostly MDMA. It's tailored to your unique physiology. Buckle in, this'll be fun. We just took ours." The look on both of their faces confirmed they had something fun planned.

Dr Blum then put a blindfold over Jake's eyes, and guided him down to her dungeon. He felt himself getting stripped and then strapped to some kind of board pressing against the front of his body, in a standing position. Jake was a little scared, especially as he had little experience with drugs, but was intrigued about the doctor's plan.

He was left standing there, and after 30 minutes or so could feel the drugs taking effect. It was a euphoria and sheer happiness building inside of him, and he couldn't help but sway his limbs in a little dance as anticipation built. Over time, he heard a commotion build, as more and more voices entered the room.

Eventually, the blindfold was lifted off of him, and his vision was blessed with Charlotte's face. He found her more beautiful than he ever had, and began to get emotional. She greeted him with a kiss that sent a delightful shiver down his spine.

Jake's head was bent to the right to meet Charlotte's gaze, and stop his face from being squished against the wooden board. She gave a short laugh, brushed her hair behind her ear, and said "lucky you, you've got the best seat in the house. You'll see everything."

Charlotte stepped away revealing an array of monitors. From every angle imaginable in full 4K he saw a room full of at least 20 absolutely gorgeous women, fully nude. Standing at the center of attention was the jaw-dropping Dr Blum in front of a wooden wall.

"Ladies," she announced. "I have gathered you for a one of a kind specimen. Truly my greatest work to date." Like a true showwoman she stepped aside, waving her arms and revealing a hole in the wall containing Jake's large caged cock. There were gasps and awes from the crowd.
