Doctor's POV
I gave Ruth her breakfast the next morning and she swallowed down two more loads of my c*m hungrily. I had started taking pills I had developed that were similar to the sperm multiplier shots we gave male slaves before s*x sessions. The shots lasted maybe an hour or so but the pills worked all day. Though the pills worked much slower so it had a gradual effect increasing how much sperm my body produced over time. I also took a pill that added nutrients to my c*m that she was guzzling down her throat. I would make sure she had plenty of real food other than just my c*m of course. The more she had my c**k the more she would want it and I was going to love it. It was an over time effect but soon she wouldn't be able to go even a few hours without my c**k inside her. I was so proud of the formula I pumped into her breasts that I created. I had been working on it for over a year twiking it till I felt I had it right. Now we could sell slaves to the outside that would only want their masters all the time with no complaints. The warden has been so pleased with my research but I still needed a male test subject and I had just the slave in mind. The one who impregnated Ruth, he would be a good test subject. I would have to move him closer as the males were kept in an area to far away for me to fully be able to monitor him. I decided I would have him moved to the girls room as I needed to have close access to him for my research. I then made the arrangements with a few attendants to have him moved and to make a space in the girls room for him. I had plans for all of them Ruth, Tina, and Cody in my coming research and it helped that Cody was the father of Ruth's babies.
I had to meet with a few patients doing routine check ups and ultrasounds. I did have a girl set to be sold to a man on the outside but he wanted her to have 'larger' assets. So I set up the procedure as I had for Ruth to make her breasts larger. Though he also wanted her to have a larger ass so I prepared my new formula for natural butt enhancement. It was designed to multiply the tissues and cells in the area to make her ass grow in size as compared to filling it with silicone. I was now waiting in my office for the girl to arrive so we could start. When she did arrive she was such a small thing. She was maybe 5ft 2in in height, flat as a board, but very pretty. She had slender curves and a lean body. I could see why the man had bought her but wanted more to her. Once the nurse had set her up on the table making sure she couldn't move around to much and disrupt the process. I told the nurse to put something between her teeth as this was going to hurt and I didn't want to mess up her teeth or have her bite her tongue. She put a bar between her teeth and attached to to her head keeping it in place. The girl was whimpering in fear on the table with tears streaming down her face. I couldn't knock her out as the drugs affected the formula I was about to use. Once she was ready I set the machine in motion. I was going to have to give this girl two large doses as she barely had any breasts at all. The machine came down producing it's long needles, calibrated a few seconds, and then plunged straight into her soft n*****s. I could visibly see the formula filling her and stretching her breasts. She screamed out around the bar in her mouth struggling to move against her restraints. The needles stayed there for about three minutes slowly filling her till there was nothing left in the machine. Once empty the needles pulled out from her chest and ascended up into the ceiling again. I walked over to her and tended to her breasts cleaning them and then working in the formula with my hands. She was on the verge of passing out I could tell but she wasn't done yet. I raised the stirrups her feet were in pushing her legs up and her ass with it leaving it off the table. I had two large syringes full of my new formula. I pierced both her ass cheeks with the needles injecting my formula and then working it in with my hands. By time I was done she was out cold on the table. I would have to come back in a few hours and do this all over again. By time I'm done she will have a slight bubble butt and at least a C cup for t**s if not larger. Whoever the buyer was would be happy with the results. I looked down at my watch and saw it was about dinner time for Ruth and I wanted to see if Cody was brought over yet.
I walked out the office locking the door after the nurse left leaving the girl on the table till it would be time to come back. She wasn't going anywhere and I doubt she was going to wake up anytime soon. The procedure always made the girls pass out for hours. I went to the girls room first opening the door to find the girls cuddled up together and Cody chained up to a bed in the front corner of the room. He was staring at the girls laying together when I came in and I could tell he was longing for something by his expression. "Ah good your here but I'm afraid I don't have much time. Ruth it's dinner time" I said looking from Cody over to Ruth in Tina's arms. She sprang up from the bed and eagerly came over undoing my pants for me. She wasted no time on my c**k and I loved how desperate she seemed. She pulled my c**k and balls out first suckling on my nut sack while jerking me off for a few minutes. "You want my c*m from those balls don't you? Are you that hungry for me little slave?" I cooed at her. "Mmm yes sir I love your c*m and I love your balls for making it for me. I've been so hungry for you please feed me all your c*m" she said lustfully gazing up at me with hooded eyes. She brought her attention back to my c**k sucking the head and then going down the whole shaft till I was in the back of her throat. She had gotten better at sucking my c**k and could now take all of me no problem. She licked and sucked with earnest till I felt myself about to c*m. I grabbed her head and forced my c**k all the way in her mouth till I was hitting the back of her throat and she gagged a little. "Ahhh I'm cumming eat your dinner you greedy c*m slut" I said as my c**k shot stream after stream down her throat and she swallowed it all. I let go of her and she licked her lips still wanting more. She sucked my c**k into her mouth again working it till I felt myself going over the edge again grunting with my release. This load seemed bigger than the first and she smiled up at me as she swallowed ever last drop of her dinner. I petted her head as she cleaned me off with her tongue making sure she got it all. I could have probably cummed in her mouth again but I was wanting something else. I wanted Cody to watch me f**k her as he seemed almost angry. "On the bed and spread your legs" I said to Ruth. She got on the beds edge on her hands and knees spreading her creamy legs apart for me. I wanted him to have a good view of me f*****g her pregnant p***y. I approached her from behind and rested my hard d**k on her ass cheeks. "Tina come suck on Ruth's beautiful t**s" I told her and she complied getting underneath Ruth and sucking in one of her n*****s. Ruth moaned clearly loving the stimulation though her t**s were still somewhat red from my punishment yesterday. I pushed my c**k into her entrance and felt her cumming almost instantly as she arched her back and screamed out with her orgasm. I love I had this affect on her body and she continued to c*m tightening her walls around my c**k. It wasn't long till I couldn't take it anymore and dumped a load of c*m straight into her pregnant p***y. I smacked her ass as I finished from the force of my orgasm.
As I pulled out of her Tina was still sucking on Ruth's big t**s and I glanced over to Cody. He was disgusted and I could tell he was jealous. "I suppose I could share her with you as I'm feeling generous. You have to suck out all of my c*m from her p***y before you can f**k her" I said towards Cody as I smacked Ruth's ass and then rubbed the area my hand mark was forming. He wanted free but he didn't like the idea of me bossing him around with her I could tell. I walked over and undid all his restraints including the cage over his c**k setting him free. "I wouldn't abuse my generosity now" I said warning him that it wasn't really a request. Cody got up and came up right behind Ruth lowering himself to his knees so her p***y was in his face. He was hesitating and it was annoying me so I grabbed his hair and shoved his face into her leaking cunt forcing him to lap up our mixed juices. He started to slurp and lick her her p***y cleaning out my c*m and her orgasm juices. His hands held her thighs firmly seeming to now enjoy it. Ruth started moaning making me hard again. "Tina keep sucking Ruth's t**s, Cody you can f**k her pregnant cunt, Ruth I want you to suck my c**k" I ordered as I got on the bed straddling Tina and putting my c**k to Ruth's lips. Cody got up and licked his lips glistening from Ruth's p***y. He centered his shaft at her entrance and we entered her at the same time making her gasp around my c**k. I laced my fingers into her hair and held her head as I moved in and out of her mouth matching Cody's speed. As he picked up his pace so did I starting to f**k Ruth's mouth faster and faster. I felt a hand fondle my balls and looked down to see Tina touching me and Ruth's sensitive bud as she sucks and licks Ruth's n****e. Ruth cries out around my c**k sucking harder around my shaft and I know she is cumming. A few seconds later Cody is grunting his release slamming into Ruth's p***y. With a good squeeze from Tina's hand on my balls I c*m into Ruth's mouth roaring out with my orgasm. I push my c**k to the back of her throat making sure she drinks it all down. We were all panting and out of breath from all the s*x. I was feeling good better then I have in a long time recently so I was feeling generous. "Cody I want you to f**k Tina while I take a shower with Ruth. She did well and deserves a treat" I said smirking down at Tina still beneath me. She smiled up at me for me rewarding her efforts just now. I grabbed Ruth's hand and we got off the bed while Cody moved to mount Tina. She spread her legs wide while on her back and Cody was towering over her. He was looking at us walking into the bathroom as he entered her p***y wasting no time f*****g her with ernest.
I heard her moans of pleasure as I turned the shower on. While waiting for the water to warm up I stood behind Ruth running my hands up and down her body. She was starting to change as her belly grew little by little everyday. In just a few short months her belly will be so full with her babies and I couldn't wait till this pregnancy was over so I could fill her with our own litter. I was still going to enjoy her pregnant body and I caressed her small bump while cupping her breast. They felt fuller to and I pinched the n****e watching a small bit of milk come out. The shots I had gave her were working and in a few days she would be close to full on lactation. Her hands followed mine touching herself with me. She laced our fingers together over her stomach and whispered "I wish they were yours sir..." "Dont worry little slave one day you will but for now we can just pretend would you like that?" I asked looking down at her beautiful sparkling eyes. "I would like that very much sir" she said turning her body to face mine. She reached up and kissed my lips putting her arms around my neck and pressing her body to mine. I wrapped my arms around her waist kissing her back. I felt her hard n*****s firm against my chest and her slight belly against my c**k between us. I lifted her legs up so she was straddling me while I held her ass. I backed her up into the shower against the wall and plunged into her sweet p***y. She moaned out loudly as I rocked my hips into her. I could hear Tina and Cody still going at it in the bedroom. As soon as Tina started screaming with her orgasm Ruth was doing the same. I bounced her up and down my d**k slamming her down on me. Just looking at her cumming made me groan with my own release filling her walls once again. "Mmm you always feel so good little slave. It's like your body just begs for my c*m" I said panting. She licked her lips and said "I love your c*m, the taste, the texture, how it fills up my p***y making me feel good. I can't get enough of it can I have more?" she asked with hooded eyes. She really was insatiable and I wasn't sure if I could keep up with her right now. "You can suck my c**k while I clean off if that's what you wish but if you want s*x I'll allow you and Cody to fuck." I tell her as I pull out and put her down on her feet. She pouts at me slightly but gets on her knees all the same and says "I want you sir and more of your sweet delicious cum." She sucks me into her mouth and fondled my balls at the same time. I hum my appreciation as I wash myself with her working her mouth over my c**k. She looked so hot down there just pleasuring me because it was what she wanted. Her luscious lips were slightly swollen from all the kissing and c**k sucking but it seemed she didn't care as all she cared about right now was getting more of my c*m. She was sucking harder working my d**k and balls over with her hands. She felt soo good that my orgasm hit me like a truck. I had to lean against the wall taking deep breaths as she sucked down my c*m making her moan around my c**k sending sweet vibrations through me. Once she was satisfied she let go of my c**k and smiled up at me and I returned her smile. I was beginning to feel real feelings toward this girl and I couldn't decide if that was going to be a good or bad thing for me. I felt depleted and didn't have anything left in me as I had just cummed several times into her. "I'm sorry Ruth but I need to go now but I want you to enjoy yourself with Cody and Tina if you would like to" I said petting her head while she was still on her knees. She just nodded and said "You'll be back in the morning right sir?" she asked. "Of course and there will be plenty more of my c*m for you ok?" She got up and smiled kissing my lips before I let her go to dry off. She washed her self as I dressed and then left the bathroom. Cody and Tina were laying next to each other panting out of breath. I smirk at them knowing at least Tina had a good time Cody looked uncertain like he didn't know what to feel about what just happened. I left the room leaving them to do as they please.
I walked back down the hall to my office walking inside to check my patient. She was still out cold on the table as I approached her. It had been a few hours and she was ready for her next dosage. She had grew considerably as her flat chest now had two round and perky breasts and her ass was more full. I injected both her butt cheeks while she was out and she didn't stir which was good it made this much easier. I checked her breasts feeling them, they were slightly firm but mostly soft meaning most of the formula had been absorbed. Her breast filled my hand and after the next dosage her breasts should be big enough to spill out of my hands. Yes it was alot considering her size when she came in but it is what the buyer wanted and I knew she would be fine after a few days. I went back over to my computers and monitors and loaded the next dose before starting the machine. I no longer felt bad about doing this to these girls anymore as my guilt was replaced with pride in my work. The machine went to work after it was ready. The needles came down calibrating once again before sinking into her soft buds about an inch deep before slowly filling her breasts. I heard a groan as she started to wake up. She started to whimper and cry as her chest grew larger before our eyes. "No more please" she pleaded but it fell on deaf ears as I didn't care about her pain. A few more minutes and the machine emptied itself and then ascended. She was breathing hard while looking down at her swollen buds and full t**s. She rested her head back and passed out again. My day was finally done and I called the nurse and told her the procedure was done and to come collect her in a few hours. I was exhausted and made my way back to my room. As soon as I laid down and closed my eyes I was out like a light with my last thoughts being about Ruth and her sweet lips being wrapped around my c**k in the morning.
