Work Text:
Teresa’s cousin Lindsay was around the same age as her. Though they only saw each other every few months, usually around the holidays, they got along well. Teresa learned things from her cousin that she didn’t hear from her own friends, and Lindsay enjoyed having someone else to play with. Her house was larger than Teresa’s, with rooms that felt hidden and a pool within walking distance. Lindsay was her cousin on her father’s side, the daughter of his older brother. They were paying a visit to their family when Teresa and Lindsay went off on their own, avoiding the adults’ conversations to have one of their own. They were both around that age when thoughts of sex and puberty were common, but still young enough that their bodies had only the smallest of curves. Lindsay was slightly more developed around the chest than Teresa, which had been a source of jealousy for her. Their rivalry had another angle that was only discovered on this visit.
When the two of them were talking on the balcony outside Lindsay’s room, they both felt a sharp, painful sensation in their lower bodies. Teresa grabbed her bag, and ran with Lindsay to the bathroom nearest her room. Both of them were wearing pastel colored panties, which made the sudden appearance of growing red spots near their crotches all the more shocking. They took off their panties at the same time, setting them on the counter. Teresa opened her bag, taking out a tampon. She opened its packaging, letting it swing like a pendulum in front of Lindsay.
Lindsay, who was standing outside the bathroom, looking for a new pair of panties in her dresser, had grabbed a pad from underneath the sink. Teresa took notice of the pad laying on the floor, ready to slide into whichever pair of panties Lindsay picked out next. The two of them stood on opposite ends of the door with their pussies exposed, feeling a rising tension in their lower bodies. Teresa looked downward at the pad, laughing to herself before opening her mouth. “A pad? I thought you grew out of diapers,” she said. “It’ll ruin the panty line if your crotch is bulging after absorbing your heavy flows.”
“I’m not the one getting off with a cotton dildo shoved up my slit,” Lindsay said.
“When I’m at home, I don’t even use tampons,” said Teresa.
“What, you bleed in the backyard?” asked Lindsay.
“The only thing I need to plug up my pussy is my dad’s cock,” said Teresa.
Lindsay stopped her gloating. “You’ve been fucking Uncle Steve?”
Teresa stood with a confident look, enough to ignore her period for a moment. “Dad wanted to make me forget about the pain entirely. We’ve been doing it for a long time, and because it’s on my period, there’s no risk.”
“No way, I’ve been doing it with my dad too. He suggested it just after I got mine, and he always asks to see my pads...” Lindsay said.
“What are you girls talking about in here?” the door opened. Steve knew that look that Teresa had when her period was about to start. Even when they were visiting family, she would want him to calm her pussy down with his cock. Steve wondered why Dan, his older brother, was following him to his daughters’ room. When they got there, the saw their daughters’ bloody pussies with no pads or tampons in them, and the two of them arguing in the bathroom about each others’ dads.
“How come you never wake me up with sex?” Lindsay asked. “Uncle Steve is putting it in her first thing in the morning.”
“You two have an entire room for this?” Teresa asked. “We have to be secretive. Soon my clubhouse will be too small.”
Dan looked similar to Steve, though he was in slightly better shape and had a more aged look to his face. “That was supposed to be our little secret. Your Uncle Steve and I have been talking about it, but we thought you two were more...”
“Innocent?” Teresa asked. “How can I be innocent when I’ve tasted my dad’s cock?”
“Uncle Steve’s an easy lay,” said Lindsay. She put her hands underneath her breasts, moving them up and down to show the fat growing, making them bigger and plumper. “I’m going through new bras quickly. I could make him cum faster than you can.”
“You’re out of practice,” said Teresa. “Uncle Dan’s dick isn’t that different from my dad’s.”
“Daddy!” “Dad!”
“I see where this is going,” Steve said.
Teresa and Lindsay put in their respective pads and tampons. They didn’t bother putting their shorts back on, and walked through the hall wearing only shirts and underwear. Lindsay’s pad was visible through the sides of her underwear, and Teresa’s string hung from hers. Once they reached the room, the door was closed behind them. Steve and Dan took off their pants. The bulges of their erect cocks were visible, with a spot of precum leaking onto Steve’s. They slid them down enough to let their cocks spring out. Dan had a more pronounced head than his brother, and a slightly thicker girth, while Steve’s was slightly longer. They called the girls over.
“I want to get warmed up first. Show me how you treat Steve,” said Dan.
“You look like you’re a good cocksucker,” said Steve, looking down at his niece.
“I’m the best,” Lindsay said.
Lindsay grabbed her uncle’s cock in her hands, and gave him a long lick along his shaft. Her nose was close to his cock, sucking up his smell. It was similar enough to her dad’s that she was confident about what she was getting into. Steve’s balls were heavy and full. He had held back from doing anything naughty with Teresa while they were visiting family, while Lindsay had been fucked by her dad just last night. Teresa and Steve were feeling pent-up and frustrated, waiting for a sexual release that would take another day or two to get around to, and even longer if Teresa’s period had ended by then. Lindsay rolled her tongue around the underside of his glans, watching it rise in front of her.
“I do love an older man’s cock,” Lindsay said. “My teacher says so too.”
“So shameless,” Teresa said back.
Teresa had adapted her fellatio style to avoid foreplay going on too long. Even when her mom was sleeping, the risk of being caught made her want to finish in a few minutes. The smell of her uncle’s cock was different than her dad’s, with an unfamiliar lingering smell in her nose that she wanted to power through. Teresa’s nipples were hard as she kissed her uncle’s cock on the lips, before taking his entire head into her mouth and swirling around the tip. Dan placed his hand on her head, messing up her hair and thanking her for doing a good job. More of his cock was swallowed up into her mouth, his balls bouncing as they got closer to her throat.
After a few licks, Lindsay looked over at her cousin. Teresa was already going deep, while she was still warming up. Lindsay removed Steve’s cock from her mouth, and planted her tongue on his balls. She could almost taste the built up cum inside. His ball hair was coated in her saliva as she soaked up every bead of sweat from his scrotum before returning to the shaft. Each long lick was accompanied by a “mwah” that contrasted with Teresa’s loud slurping. She tasted a drop of precum on Steve’s dick, and took it onto her tongue. Her nose was getting closer to his pubic hair, and the smell was going stronger. The shape of Steve’s cock felt wrong to her, but she wanted to show Teresa that she was far naughtier.
With the girls working on their cocks, the brothers looked down at their petite bodies. They were both in the early stages of puberty. They had only the tiniest budding breasts, yet their asses looked quite round from this angle. Both of them had a towel underneath to absorb any period blood that might come out while they were vigorously sucking. Lindsay shot Teresa a smug glare with a cock in her mouth, while Teresa retaliated by grabbing Dan’s shaft. She stroked his saliva-soaked cock with her fingers, gripping it gently enough to make him hot and hard inside her little mouth. The taste of dick filled her nostrils, making her entire body warm and tingly. For Teresa, it was the first time she had sucked a dick that wasn’t her dad’s, and the thrill of it was making her pussy leak with blood and love juice alike.
“Your wife’s got a tough job. So Teresa’s been tending to you while she’s too busy to have sex?” asked Steve.
“I’ve thought about bringing it up, but she always wants to go to sleep before I can tell her,” said Steve.
“For me, this was my wife’s idea. Lindsay’s grades were slipping, and the wife said she couldn’t see her friends until she sucked my cock. It was supposed to be punishment, but she came to like it. She agreed that I could fuck her, but only on her period,” said Dan.
“She needs to learn her lesson. Teresa’s grades are holding up well. Maybe because my cock’s inside her when I help her study,” Steve said. “Feeling close?”
“Real close,” Dan said.
Teresa felt her uncle’s cock slide across her tongue. Her mouth was close to the base. Lindsay was sucking on her dad’s cock, holding his balls in her palm. She was going to make him cum seconds before her. With their cocks inside the girls’ mouths, it was difficult to tell who came first. Teresa gasped, and Lindsay nearly choked on the amount of thick cum dripping from the glans of the older men. It filled their cheeks. Their jizz was so thick and gooey that the girls could almost taste the sperm floating in it. The cocks were pulled from their mouths, and the girls were asked to open up and show them. They each had a white puddle of semen on their tongue, which was quickly getting watery and losing flavor. Closing their lips, the girls swallowed.
“It’s so thick. I can feel it in my stomach,” Lindsay said.
“Dad was saving that for me. It’s not fair you get to drink it,” Teresa said.
“Teresa, don’t be angry at her. One load isn’t going to be enough to drain me,” said Steve. “I was going to see if I could taste your daughter’s pussy, but Teresa wants her favorite dick inside her.”
“Lindsay’s thinking the same thing,” said Dan. “We’re already here, we may as well go all the way. Watching her suck you off got me raring to go.”
“You did a good job, Teresa,” said Steve. “Let’s see how your cousin does it with her dad. Maybe we can learn a few things.”
Everyone took off the rest of their clothes. Teresa and Lindsay stood beside each other. Drops of red were showing at the edge of their pussy lips. Seeing them naked and side by side was making the men' s cocks twitch. Though the two of them weren’t as youthful as they had once been, their cocks were rock hard and twitching at the sight of two young girls acting sexy in front of them. Lindsay wanted to be on top, and told her dad to lay down on the floor. His cock stood straight up.
Lindsay crawled across the floor, spreading her legs and hovering her bloody pussy over his dick. She groaned from the pain in her lower body, and kept lowering herself until Dan’s cock spread her lower lips. His shaft was covered in her period blood, but he didn’t care. A mixture of blood and pussy juice warmed his cock as it settled into the familiar depths of his daughter’s pussy. “Daddy’s cock is the best,” Lindsay said. “It fits me perfectly.”
Teresa was on all fours. In her bent over position, her asshole and her pussy were pointed directly at her dad, both of them breathing and waiting for more. Steve got on his knees behind her. He ran his hands across her back, caressing her breasts. Teresa’s nipples were more tender when she was on her period. A trickle of blood and love juice left her pussy as she gave out a cute moan. His cock spread her open, pushing inside with a single wet thrust. Her insides were slick and warm, covering the two of them with smears of red. Teresa caught her breath, and curled up her fingers around the towel on the floor. She wiped a bead of sweat off her forehead, and told her dad to continue.
“My dad’s hits all my best spots,” Teresa said.
“Are you feeling better?” asked Steve.
“You’re the only tampon I need,” Teresa said.
Lindsay gave her a confused glance. It was the strangest flirting she’d heard. Lindsay put her hands on her dad’s chest, and bounced up and down on his cock. The wet sounds from her pussy grew louder with each pump. The heat of his cock was pushing away the pain in her lower body. Lindsay ran her hands down her stomach, starting with her belly button. She traced the length of his cock inside her. Her clit was so hard it was throbbing, matching the intensity of her dad’s pulsing cock inside her. Lindsay stopped for a moment. She got off her dad, letting a drop of blood land on his glans, and faced her butt towards him instead. Her desire to one-up her cousin was the most important thing to her at the moment.
Teresa felt her dad’s hands touching her nipples. He pinched and tweaked them, sending a sharp burst of pleasure down her body that she felt all the way in her pussy. Her snatch tightened up further around him, keeping him in trapped in her bloody slit. His cock was getting close to her womb with each thrust They had scheduled their fucking to make sure Teresa was doing it on her safe days, but few days were truly safe. Teresa insisted on doing it raw, and the risk of pregnancy was always there. Her dad’s hairy cock made her pussy squelch, doubling over in delight from having his throbbing member soothe her menstrual cramps.
“You don’t have to rush,” said Lindsay. “You can take as long as you want. That must be new to you.”
“I thought Uncle Dan’s cock was so good that you couldn’t endure it for very long. Is your twat so sensitive you can’t handle sticking something in it?” asked Teresa.
“Daddy, make me cum in front of her,” Teresa said, speeding up the pace of her pumping. She was going harder and stronger, making more love juice froth and splash out onto her dad’s legs. Teresa crawled across the floor, with Steve following behind her on his knees. She approached her cousin, and placed her hands on her chest. Lindsay felt Teresa’s hands on her breasts, squeezing down on the fat that had started to grow beneath. Teresa was feeling naughty. She had played around with her friends, the ones who had their periods, and had no shame in using what she knew on Linsday.
Teresa stuck her tongue in Lindsay’s belly button, circling around her navel before licking upward. Beads of Lindsay’s sweat were caught on her tongue. When she reached her cousin’s nipple, she latched onto it and started to suck. Lindsay’s pussy was getting hotter. A splash of her period blood landed on Teresa’s arm. That wasn’t enough to get Teresa to stop. She kept sucking on Lindsay’s tit, swirling her tongue around her hard areola and making her squeal with pleasure. Lindsay was getting closer to orgasm, each word growing breathier as her dad’s cock plunged further into her depths.
“Teresa’s playing with my titties,” she said.
“That’s really hot,” Steve said. He stuck his middle finger, wet with Teresa’s love juice, inside her asshole. That was enough playing around. He wanted to make sure Teresa was still paying attention to him when it was her turn to cum. Teresa gave out a cute moan as her dad’s cock grinded against her vaginal folds, stirring up her love juice into a pink froth, mixing together with her blood. Teresa was blushing bright red. She gave Lindsay’s nipple a few more licks before putting her hands on her cousin’s shoulders. Lindsay tried to say something, but her words were stopped by Teresa.
“What are you doing there?” asked Dan.
Teresa put her lips on her cousin’s. The two of them locked in a sweaty embrace as Teresa’s hard nipples pressed up against her cousin’s own. Lindsay’s hard tips touched Teresa’s areola. Their tongues dug around in each others’ mouths like they were trying to get the last drops of their dads’ cum out of each others’ cheeks. Their sloppy kiss made their fathers’ cocks throb. Steve wanted to give Teresa a little extra push for being so naughty in front of him. Seeing her do it with her cousin had an extra naughtiness that doing it with her friends didn’t have. He licked his middle finger, and slid it inside Teresa’s warm and tight butthole.
Overcome with arousal, Teresa climaxed onto Lindsay’s stomach. A spray of bubbling love juice and a few drops of period blood spilled out. Lindsay came after her, squirting in her cousin’s direction. The two of them broke their kiss, saliva dripping down on their naked bodies. Their dads’ cocks exploded inside them. Hot, white gooey cum filled their insides. The warmth and stickiness of a fresh load made them forget that they were on their periods. All they could think about was the orgasmic pleasure spreading down to their toes. Their breaths were heavy, hanging in the air of the chilly room. They were so hot that Steve thought he was able to see their breath for a moment. Teresa and Lindsay collapsed onto the towels with their legs spread. Their pussies were leaking, making small squirts each time.
“Who came first?” asked Lindsay.
“I think I did. I was pretty pent-up,” Steve said.
“It felt so good I don’t really care. Only you girls do,” said Dan.
“We can clean you up and give you a hand job,” said Lindsay. “I want another taste of Uncle Steve’s cum.”
“It’d look better on your face than in your mouth,” Teresa said. “Uncle Dan’s probably never given you anal.”
“I... I can handle anal! It’s just that my butt’s weak,” said Lindsay.
Steve and Dan looked down at their daughters, telling them to stop arguing. They should take a shower and clean up first, and then they could think about having more sex. They would wait until after dinner and their wives were doing something else. Teresa and Lindsay begrudgingly agreed, even if they had to share the shower. Being in such close and soapy quarters meant that they felt each other up during the shower, trying to make each other cum again as more period blood circled the drain below. After their shower was done, they went with their respective pads and tampons.
During a quiet period of their stay, when Steve was looking through the books and vinyl records that his brother had in his library, Teresa approached him. She asked him a question. “Dad, what would you do if my periods stopped?”
“We’ve been very careful about when we have sex. If that ever happened, I’d want to support you,” Steve said. Teresa felt a small cramp in her lower body. She hadn’t missed a period yet, but she had read that having sex during them wasn’t a way to completely prevent pregnancy. She put her hand on her dad’s crotch, rubbing his dick through his pants.
“Love you, dad.”
