Daughter Cum Boob

Chapter 3

I pounded on the door. “Mark, what are you doing in the shower? Trying to drown the dirt? Hurry up, I need to shave!” When I didn't get an immediate response, I added, “Mark! Do you even hear me?”

“Um, five minutes Dad!”

Mark's voice sounded strange. “Not a second more!” I demanded. I went downstairs to put breakfast dishes in the dishwasher while I waited. It didn't take me the full five minutes, but I headed back upstairs anyway. I was in for a shock when I got there.

Through the bathroom door, I heard Mark's voice.

“Crap Lynn! It's already been four minutes. You're going to have to hide in the closet so Dad doesn't catch us. Ahhh!”

It sounded like a noise I had made a few months ago when I hadn't been able to keep Lynn from sucking my dick. I had been able to keep anything else improper from happening between us since then, but that didn't mean I didn't think about it every day. I knew I should bust down the door and stop whatever was happening, but my cock was already growing hard in my boxers. All I could think about was the memory of my little girl giving me head.

“Easy Lynn! I want to dump this load inside you later, not all in your mouth right now!”

What the fuck! My kids had gone way beyond what I had started with Lynn. My head was spinning. Had I been the cause of this when I let Lynn suck me off? Had Mark and Lynn been screwing each other before he left for college? I needed to know the answers to these questions, but I needed to do something else more. The desire for my daughter, which I had held at bay for several months, overwhelmed me. My cock was fully hard, and I fished it out of my boxers.

“Don't worry, I know what I'm doing. I hardly ever make you shoot off in my mouth when you want to get your release between my thighs.”

If I had any chance of not acting on my incestuous urges, it was gone when I heard my daughter talk about my son cumming between her thighs, her smooth creamy thighs. I opened the door and barged in.

Mark's immediate response was, “I'm dead!”

Lynn's was, as she looked back at me over her shoulder, “Oh shit! Daddy...”

Mark was sitting on the counter of the bathroom sink. The only reason the shower was running was to cover the noises Mark and Lynn might make as she played with her brother's hard dick. She was bent over facing Mark as she played with his cock. Her legs were spread, and I could see the sweet juicy pussy I wanted to bury my shaft in. She turned her head when the door opened, and her words trailed off when she saw my hard dick pointed straight at her.

Lynn's pussy was wide open from the excitement of sucking on her brother's cock. I grabbed a hold of her waist and sunk myself into my own daughter's pussy with ease. Lynn's eager pussy clamped down on my shaft and we both moaned in ecstasy! Never releasing my grip on my daughter's waist, I started pumping my dick in and out of her wet cunt with swift hard thrusts. I admired the way my little girl's ass jiggled and shook as I fucked her hard.

“What the fuck is going on?” Mark cried out. The look of disbelief on his face clearly indicated that he couldn't believe what he was seeing. “Fuck! I thought I was a dead man!” Mark watched his old man screw his little sister for a while before he stated, “This can't be happening.”

I was more interested in what Lynn's body was making me feel than anything my son was saying. I hadn't been this excited since my honeymoon. “Oh Lynn! Letting your Dad ram his hard cock in and out of your snatch is an even better way to show you love him than sucking his cock! Wouldn't you agree?”

“Ugh! Hell yeah! And sticking your rod in my belly is an even better way for you to show how much you love me than sticking it in my mouth,” Lynn moaned.

“This is so fucking hot!” Mark exclaimed. My fucking had driven Lynn's body forward. She was leaning on her brother for support, and her big tits had to have been slapping his cock around as I continued to fuck my little girl for all I was worth. “But you've got to pull out Dad!”

“Hell no son! If you can dump a big old load of family jizz into your little sister's belly, so can I!” I protested.

Mark yelled, “But I haven't been cumming in her!”

“Bullshit!” I cried. “I heard you talking about how she shouldn't suck you so hard because that might keep you from cumming between her thighs later.” I started banging my daughter even harder and faster to show Mark I had no intention of stopping.

“Yes, I've been fucking Lynn until I cum,” Mark admitted; then he added. “But I've been wearing condoms!”

Oh shit! I had really looked without leaping this time. The words sunk into part of my brain, but I was still fucking away at Lynn. I had just assumed my little girl was on the pill when I heard Mark talking about cumming in her.

I stared down at my daughter's narrow waist where I gripped it. I was really tugging on her breeding hips for all I was worth. Her round ass seemed to demand my cock and my cum. I couldn't see her breasts, but I still remembered how round and ripe they were. Lynn's body was made to entice and satisfy men. I was going to have a hard time stopping like I knew I needed to.

This time it was Mark's turn to ask if I was listening to him. “Yes I heard you!” I snapped. “I just can't stop showing Lynn how much I love her with my cock!”

“Knocking your daughter up isn't showing her your love!” Mark screamed.

“I don't know!” Lynn gasped. “I feel like I'm getting a lot more love from Daddy's cock without anything between him and me. And I feel like I can show him that I love him better without that layer of latex in the way. It's like it was a barrier between us Mark.”

Mark screamed again, “It was a barrier between my potent cum and your fertile belly!”

It was all too much for me, the fast fucking, the danger of unprotected sex. I knew that I was beyond the point of no return. “Lynn, Daddy's going to show you how much he loves his little girl by trying to father a baby in his own baby!”

Lynn might regret it later, but she just encouraged me. “Do it Daddy! I feel sorry for all the girls and Dad's who never get to feel something like this.” She wasn't faking her enthusiasm. I could feel her pussy spasm into orgasm around my jizz squirting dick!

It was apparently a turn on for Mark even though he had been trying to get us to stop. He groaned, and I saw him reach his hand under Lynn's body. From the motion of his arm, he was obviously jacking his shaft. He climaxed right along with us.

Lynn straightened up, and twisted at the waist to kiss my neck. Lynn and I were both completely overwhelmed by what had just happened. To be honest, it hadn't really sunk in with me yet. I was moving, basically on instinct, so she could kiss my lips when Mark spoke. “Wow! Lynn's tits really do look amazing covered in cum!” Mark admired.

I had been feeling my cock growing soft inside my daughter's delightful pussy, but suddenly my fetish for cum on a woman's breasts was breathing new life into my dick. “Let me see in the mirror!” I growled.

Mark had decorated his sister's tits with way more cum than the nameless high school boy I had run off. Lynn must have really worked her brother up. I reached around my daughter's waist and started fingering her clit as I fucked her from behind. I leaned over my little girl's shoulder so I could get a better look at all that glorious cum on her boobs. “Yes! That's fantastic work Mark!” I admired. “You really showed your sister how much you love her by showering her tits with all that cum. Don't you feel it Lynn?”

“Yeah!” Lynn moaned. “Oh! I think I'm having multiple orgasms!” My daughter's head nuzzled up against mine, and she resumed kissing and licking my neck as I continued to fuck her. “Are you going to do it again Daddy? Are you going to show your little girl how much you love her by trying to make a baby in me a second time?”

What can I say? Maybe I could get away with pleading temporary insanity, if it was permissible to use your naked daughter as a defense exhibit. I was helpless; I had to give my daughter what she wanted. “Yes! I'm going to do it baby! I'm going to fill you up with cum a second time!”

“This is fucked up!” Mark commented, but his cock was hard again also as he watched his sister and father putting on a live sex show.

“I'm doing it Lynn! It feels so damn good! Daddy's showing his little girl how much he loves her with his cum!”

I was back in Lynn's room with her and her brother. They were still naked. I had on my boxers and a wife beater. My cock had deflated after fucking Lynn twice in a row, and I had tucked it back into my boxers. The evidence of what I had done with Lynn was dripping down her thighs.

“What are we going to do about this?” Mark asked. “Mom's going to freak if Lynn's a mother before she graduates high school.”

“I think the bigger problem would be if she ever finds out that Dad is the father,” Lynn's observation was accurate, but not all that useful for dealing with the situation.

Finally I had an idea. “Sperm warfare!” I announced.

The response, “Huh?” came at me in stereo.

“It's an article I read in a science magazine. When two different men have sex with the same woman, their sperm don't all try all go racing for the egg. They start attacking each other, and the chances that the woman will get pregnant go down instead of up.

“I don't see how that...” Mark stared directly at his sister's gooey pussy as the implications of my plan dawned on him. “Oh my!” was all he could finish with, but his cock was standing at full mast again. Lynn certainly was a sexy little thing. She had no trouble causing erections in her two closest male relatives. Mark's body was convinced, but his head wasn't. “But don't we just have a new problem if Lynn catches anyway?”

Lynn giggled, “Yeah, Mom won't know who to kill first.”

“That's not funny!” Mark snapped.

“Sure it is,” his little sister teased. “It would be your grand joke on the universe. You're awfully grumpy for someone who doesn't take anything seriously. Relax, you're getting a chance to fuck me without a rubber. Look at your cock. It knows this is a good idea!”

I added, “And unlike me, you'll actually be doing something useful for your sister when you show her how much you love her with your jizz.”

That last one finally seemed to convince my son. Lynn was already lying on her bed with her legs spread invitingly for her brother. Mark mounted his sister, and his cock vanished almost instantly into the depths of her well fucked cunt. “I've never ridden bareback before,” Mark commented. “I've worn a rubber every time I've had sex up until now.” Mark pumped in and out of his sister a few times.

“You weren't lying about being able to show your love better without that layer of latex between us!” Mark gasped as the pleasure of unprotected pussy assaulted his cock.

“I figured that out with Dad, but I'll let you demonstrate that lesson again. Tommy and that dude from the start of the school year were in and out so fast I didn't realize it with them,” Lynn cooed as her brother fucked her. “I think I'm going to want lots of this kind of attention from here on out”

“Wait, does that mean...” I started to ask.

Mark buried his cock to the balls in Lynn's belly as he finished for me, “That Dad and I get to fill you up with liquid love from now on?”

“Yep!” Lynn confirmed.

“Oh fuck!” Mark called out repeatedly. I could tell he was exploding cum inside his sister. My cock was getting hard for the third time, so I stripped off my remaining clothes to be as naked as my children.

I walked around to the other side of my daughter's bed. “You know honey, I never did get a second blow job from you.” I fed my cock to my daughter, and she slurped it down eagerly.

“Damn, Dad! Aren't you even going to wait for me to pull out?” Mark jerked his cock out of his sister's body and hopped away from the bed.

“Nope! In fact, you need to get it up again. I was planning on having Lynn suck me until you give her a second helping of brotherly cum.”

“What?”

“Well, I came in her twice; you blew your first load gloriously all over Lynn's big tits.” I reached down and started playing with my daughter's wonderful jugs as I continued, “My sperm still have the advantage. You need to fuck your sister again.”

Mark started jacking on his shaft. “Oh, I didn't realize. I hope my little sister knows that I'm always willing to show her how much I love her with my cock and my jizz!” Lynn just nodded as best she could with my dick in her mouth.

“Ugh!” Mark grunted. His cock had become hard enough to penetrate his sister again. “I thought I was going to be able to wait until Dad finished doing this, but I can't. I don't know why having two of your closest relatives inside you at once seems so much weirder and more perverted than one, but it does. Still, now that it's hard again, I just can't wait! I have to be inside you again right now Lynn!”

Mark looked at my cock in Lynn's mouth one last time before penetrating his sister again. He was right; this family threesome was certainly odd, but incredibly erotic. I could feel a thrill shoot through me as he sunk his cock into Lynn, and I'm sure he was getting turned on by the sight of Lynn sucking on my cock like a baby with a bottle.

“Since we're going to be doing a lot more of this from now on,” I announced during our family orgy, “we have to be more careful around your mother than you two were around me.”

“Yeah!” Mark panted. Lynn obviously couldn't say anything.

The idea of being able to do this every time my wife left the house was too much for me. “Oh fuck! I'm cumming again!” Having his own father fill the mouth of the girl he was fucking set Mark off. It probably didn't make it any easier to control his cock that the girl in question was my daughter and his sister. I don't know if Lynn came, but she looked plenty happy to be extracting sperm from two men at the same time. As much as she seemed to like sex with relatives, she probably had cum, but after three orgasms in half an hour I was too dazed to ask about it then and the subject never came up later.
