Family Duty

Synopsis

A man helps his stepdaughter and her girlfriend get pregnant by being the sperm donor. In the course of things, he not only ends up impregnating both girls, but he awakens their desire for some occasional cock.

Three Months Later

John rolled over and looked at the bedside clock. It was almost 7 AM, still pretty early for a Saturday. He stretched and felt his cock plastered against his leg, stuck there with the cum from sex with his wife the night before. She had been unusually horny lately, averaging two or three times a week for the past month.

He looked over at his sleeping wife. At 50, Angie was still hot. She had small, 34B tits, but long, luscious hair and a perfect, heart shaped ass. Her pussy was still tight - and invariably sucked the cum right out of him. Like her daughter, who was now 4 months pregnant with John's baby, Angie was a "gusher" who flooded his cock with her pussy juice whenever she came. He never tired of trying to make her cum.

As he lay there, John started thinking about his stepdaughter Amber and her partner, Joanie. Both of them were now sporting cute little baby bumps, courtesy of his potent semen. Better yet, the lesbian couple had decided that they enjoyed adding some cock to their sex lives, and they decided that John was just the man to give it to them. So for the last four months, he'd been living the dream of fucking two hot pregnant chicks - both of whom were carrying his babies!

Thinking of his hot hot daughter and her girlfriend naked on top of him caused John's cock to come to life. In a matter of moments, he was standing tall at his full 8 inches - looking for a way to relieve the pressure. He looked over at the back of his sleeping wife, and he inched forward. He slid his fingers between her ass cheeks, finding the wet center of her pussy. He slipped his fingers into the opening of her cunt, coating them in their mixed juices. She shifted her ass slightly as he fingered her, then began to push back against his hand as his finger found her clit. After some gentle circles, he began to rub her nub in earnest, causing her to moan and squirm.

Sensing she was ready, rolled her onto her stomach and he rolled on top of her. His throbbing cock pushed past her ass, as she lifted her hips slightly to give him full access to her pussy. She was so wet that the tip slipped into her hole easily, and in a few seconds his entire shaft was buried in her once again. Thanks to the two rounds last night, this time took some effort. After almost 20 minutes of pounding, he could feel the cum boiling in his balls. Just as Angie had her fourth orgasm of the morning, John buried his cock in her pussy and splattered her insides with cum for the third time. His cock shrank quickly and the fat head slipped out with a loud, "Plop!"

John kissed Angie neck as she sighed with satisfaction. After 12 years, sex with her was still hot.

"Well, somebody is certainly full of energy this morning," she said, as she rolled onto her back. "That's three times since last night...very impressive! My belly looks like I'm 3 months pregnant just from all that cum!". As she spoke, she patted her belly. It was indeed rounded, some from his 3 seed injections and some due to the creeping muffin top that had plagued her for the past few years, ever since she started exhibiting symptoms of menopause. Still, he found her belly enticing and he never turned down a chance to fill it.

"We'll, it's your fault for being so sexy...I can't help it if my cock can't control himself! What are your plans today?"

"Well," Angie said, "I was going to take the girls out to do some shopping for the babies. I still can't get over the fact that they went and got in vitro fertilization without telling us. I can see how happy they are, but I guess I'm just old fashioned. Although I still don't know how they get by without having a wonderful cock like yours. Nothing beats that feeling of being filled up...and filled!" As she spoke, she gave John's cock a tug, which caused it to twitch back to life.

"Be careful - once you initiate the launch sequence, you're committed!", he joked. He was glad his wife had no idea that he was the one who had knocked up her daughter...and her lover!

Angie let go of his semi-flaccid hard on. "Okay, I've got to get going. It's going to be a busy day. Oh, I told the girls I would send you over this afternoon to put those cribs together. They said they would treat you to dinner as payment."

John smiled, knowing the "treat" the girls had in mind had very little to do with food!

Later that afternoon, John knocked on the door to the girls' apartment. Joanie opened the door, beaming at him. Already a little "curvy" before she got pregnant, she had really filled out with the baby growing inside her. What had started out as 38DD tits had grown into 44E's. And much to John's delight, the pink areolas and nipples had quickly turned very dark. Her belly was quite big already - she looked like she was closer to 6 months than 4 months. That didn't stop her from keeping her pussy neatly trimmed, with just a narrow "landing strip" above her smooth labia.

"Hi, Dad!", she exclaimed with real enthusiasm. Ever since he had knocked her up, John had become "Dad", which was kind of a turn on. "Come on in - Amber's just finishing dinner. We have some chores for you after you're fed!"

John followed her into the dining room, and Amber came in from the kitchen carrying a bowl of pasta and sauce. She put it down and gave her Dad a hug. The fact that all their interactions were innocent - until they were naked and fucking - was another turn on for John. Amber wasn't quite as big as Joanie, but her baby bump was prominent. Her tits were now a 38C and that sat proudly on top of her growing belly.

Over dinner, the three caught up on things. Both babies were growing well and the mommies were doing perfectly. Most people had gotten over the shock of both girls being pregnant at the same. For his part, John enjoyed seeing him blossom and he was glad they were so happy.

After dinner, John set to work on the cribs. Fortunately the directions weren't too complicated and after ninety minutes he had them both assembled. He came back into the living, where the girls were snuggled

Ed on the couch, and sat down in the arm chair.

"Okay, I think everything is set. All you need to do is put the sheets on. Anything else that needs doing while I'm here?"

The girls looked at each other and Amber gave Joanie a conspiratorial wink. "Well, Dad, now that you mention it...Joanie and I could both use a little attention. Now that we're into our second trimester, we're both incredibly horny. And since it's all your fault, your cock should be the one to take care of it!"

John looked at both girls and smiled. Despite three rounds with Angie last night, he couldn't tell his girls "No".

"Well, if that's the price I have to pay for planting my seed in both of you, then I guess I'll have to make amends!"

Both girls jumped off the couch and headed straight to the bedroom. By the time John caught up to them, Joanie had already pulled off Amber's nightgown and was suckling her big breasts. John walked up behind Joanie and reached around her swollen belly, slipping his hand down into her sopped panties. He flicked her clit, causing her to moan, then he sank two fingers into her soaked pussy. A few seconds of movement and he could feel Joanie starting to clench around him. It was long before her cunt let loose with a torrent of juice that soaked his hand to the wrist.

Meanwhile, Amber broke away and climbed onto the bed on all fours. "Please, Dad, give me your cock! My cunt is aching for it...and the baby misses her daddy!"

John slipped his hand out of Joanie's panties and unbuckled his belt. In a flash, his pants and briefs were in a pile on the floor and his fat, throbbing cock was lined up with the entrance to his daughter's cunt. With one quick thrust, he was buried balls deep in her pregnant pussy. He reached around and grabbed her swollen belly from each side, as he started to move slowly in and out of her. Amber moaned as her father's cock filled her up. Not for the first time, she thought about the fact that while she loved Joanie, she did enjoy cock. The fact that it was her stepdad's just made it deliciously wicked!

While John plowed Amber's pussy, Joanie moved in front of her, laid on her back, and offered up her wet pussy. Amber her lowered her head and ate her girlfriend's cunt like a madwoman. Joanie closed her eyes and used both hands to knead her own tits, pulling on the rock hard nipples. As she did, tiny drops of white milk started to drip from them. Joanie spread it around her areolas, making them glisten.

John watched the girls playing and - much to his surprise - he felt the stirrings of an orgasm deep in his balls. A few more strokes and he was unleashing another torrent of hot cum into his daughter's cunt. Amber came at the same time, her scream muffled by Joanie's clit in her mouth.

"Wow, Dad...that was intense! Been saving it up?"

"Um, actually - no," muttered John, "I fucked your mother three times last night. But you two are so hot, that I just can't help myself!"

Both girls smiled, and kissed John on the cheeks. "Well, good," said Joanie, "because you're not leaving until I get mine!"

Four Weeks Later

"Honey, would you mind throwing the laundry in the dryer? I'm just wiped." Angie was lying on the couch, watching TV. She had been feeling a bit peaked lately, so John was doing double duty at home, as well as helping the girls. He was somewhat glad that Angie's sex drive had finished a bit in the past few weeks - because the girls seemed to be hitting a peak. Some days they demanded two fuckings a piece, and reminded him that it was his fault that they enjoyed cock so much. So Angie's hiatus helped John keep up with the demands of his daughter and her partner.

John took care of the laundry, then tidied up the kitchen. He offered to make some dinner, but Angie said she wasn't feeling up to it.

"Why don't you go see if the girls want anything? You might as well spend some time with them while I'm getting over whatever this is," Angie told him.

John kissed her on the cheek and said he wouldn't be too late. He drove over to the girls' apartment, and they were thrilled to see him. Much to his surprise, however, neither of them wanted sex. Instead, they just wanted to lay in bed and cuddle with their baby daddy. John could hardly say No, and soon he found himself as the filling in a pregnant babe sandwich. He lay in bed, stroking both pregnant bellies and feeling the little kicks from the inhabitants. Amber was having a girl and Joanie was having a boy, but both babies were impressive kickers.

Joanie's belly was continuing to expand at an impressive rate -- people routinely asked her how many days she had left. Amber's belly was growing but she had only gained about 10 pounds, all belly and boobs. Her ass was just as tight and luscious as it had always been, which made her swollen belly even sexier. As he lay there touching both girls, he still couldn't believe the way things had happened. He couldn't imagine anything better that a man like him, with a pregnancy fetish, could ask for.

When John got home, Angie was already in bed. As much as he wanted to unleash the built up frustration that the cuddle session had generated, he could see that she was out for the night. Oh, well - there would always be tomorrow with girls!

The next day, John came home to find Angie seated at the kitchen table. She had some papers in front of her, and it looked like she had been crying. John went to her side and hugged her. She didn't say anything, but motioned for him to sit down at the table. John took a seat, then waited for Angie to be ready to talk.

"I went to the doctor today, and I know now why I haven't been feeling well. John, there's no way to make this easy....I'm pregnant. Six weeks. They even did an ultrasound just to confirm. He said despite my menopause symptoms, it appears to be a completely normal pregnancy. Please say something, honey."

Angie looked at John, unable to read the look on his face. For his part, John's mind was awhirl, trying to understand what he was hearing. Were there really three women pregnant carrying his babies at the same time? Had he knocked up his wife, at the age of 50?? Holy fuck, the sex is going to be amazing!

John shook himself from his reverie and took Angie by the hands. "Honey, that's amazing! I'm thrilled! I never thought we would have a child together. This may have not been what we planned, but it will be amazing. We can do this together!"

Angie cried, but John could see they were tears of joy and relief. She came over and sat on his lap, kissing his cheek and his lips. Her kisses quickly became more passionate, and John felt his cock stirring.

"Oh, honey, I'm so glad to hear you say that. I want this baby with you - even though my own grandchildren will be older than this baby! I can't wait to go through a pregnancy with you. And now, how about you help me release some of this tension? The afternoon has been agony, not knowing how you would react. And besides, it's been too long since I've had that monster cock inside me! At least I don't have to worry about you knocking me up again!"
