I woke up with Katie pressed against me, she was already awake and leaning into me caressing the big black cock she had strapped to me the night before.
"Hi," She warmly smiled.
"Hi."
"Did Shelby ever tell you about the time we saw daddy... jerk off" She asked looking for the right words.
"A little,"
"I remember it like it was yesterday, it's seared into my memory, and I honestly think it shaped us in ways we can't even understand. You've been in daddy's study..."
"Uh-huh,"
"So, mom and dad had just left to go to some office party for moms work. So, we decided to sneak in and take a few drinks... we had never tried alcohol and we just wanted to know what it was like. Even though the door is never locked we rarely get to go in his room, and we already fault naughty for breaking that rule. We're opening the different bottles and smelling them to figure out the difference between a bourbon, a scotch and whiskey. I finally take a sip from the first bottle and hand it to Shelby and she tries it too and do the same with the other two. It wasn't enough to get us drunk or even to really feel it, just tasting it.
That's when we hear daddy call out that he was home and we could tell he was already just down the hall. Later he told us he hadn't been feeling good and came back home while mom went on to her party. We quickly put the bottles away and hid in the closet - the one with the slatted door.
Daddy comes in and turns on the tv and plops down in his chair, he's like maybe 10 feet away from us, and we could clearly see him. He turns on the DVD player and starts watching a movie, and its porn. Can you believe it?" She asked turning to me with a bit of embarrassment.
"Any way, we're there, stuck in the closet and watching this happen. We could see the tv okay, not great, but enough. And we see this scene with a really fit athletic girl, and she's sucking this older guy's big dick, making all these moans and sighs and embellished high pitched responses; 'yes!' and 'you feel so good in my mouth!" Kat acted out, turning me on greatly.
"Well daddy unzips his pants and pulls them down, and my eyes lock on. Daddy's stroking his dick and playing with his large balls. Neither one of us had ever seen him naked, and the only penis we had seen was our brother's. Maybe it was the angle or just my mind playing tricks, but even now thinking back on it, daddy had a big dick, I'd guess 8 inches or so." She said measuring him up on the dong.
"You know they say that every girl is looking for a man that reminds them of their daddy. Well, I know for me that's been true, because every guy I slept with I was mentally comparing to daddy's cock." She shared and slipped the black cock off of me. I was throbbing as she curled her fingers around me just feeling me in her hand.
"It occurred to me years later that the girl in the video looked a lot like Shelby. You know I've always looked more like mommy, and Shelby looks more like daddy's sister, aunt Tricia. They're both taller and slim and have more of an athletic frame. I've wondered if that's why he always seemed to favor her. I wonder if I would have been more into sports and stuff if I was taller and hadn't developed such large boobs so early." She mused rolling over and groping her large breasts kneading them in her hands. Kat was right, she looked a lot like their mother just 20 years younger.
"Well," She says getting back to her story, "Daddy's taking his time going real slow watching the movie and toying with his prick," Kat mimed stroking a cock between legs showing me just what she had seen her dad doing.
"Every so often he would stop and just hold it. It was thick, manly and so wrong for us to be watching. I looked at Shelby and she's just as awe struck as I was, we made eye contact and just shook our heads in disbelief." She rolled back straddling me and slipped the harness off, then cupped my balls that had pulled tight against my body in her hands.
"Does it hurt?"
"Yes," I responded with a shaky moan. Kat reached over and opened Shelby's nightstand. She pulled out a bottle of massage lotion. She popped it open and drizzled the oily lube on my sack and tenderly messaged my balls. She pulled and tugged them away from my body stretching out the scrotal flesh as she told the rest of the story.
"So, daddy picks up the pace, and now seems determined to cum. Daddy grips his cock and his hand is moving so fast up and down the top half of his dick while holding his balls tightly. His legs shook, and he huffed several times as we watched his head erupt with a flow of pearly fluid. He sat there for several minutes stroking his dick slowly working all the cum out. He cleaned himself up with some tissues and then turn off the tv and left the room. We heard him go down the hall to their bedroom and close the bathroom door. We made our escape to my bedroom, where we sat in shock for several minutes before we just busted out laughing."
Kat grew silent and sat down between my legs putting her legs over mine while still toying my balls for what felt like an hour, her hand never touching my dick, just pulling, pinching and caressing my sack.
"She really loves you, you know."
"What?" I was having a hard time comprehending.
"Shelby, she really loves you. I remember when you guys first met it was at that Mud Race thing that you guys do. She called me that night and went on and on about this cute guy she met, and how much you have in common, you guys grabbed something to eat and you asked for her number. She was beside herself wondering if you would actually call."
Shelby and I had participated in a lot of runs, marathons and Tough Mudder competitions, we loved the competition and it gave us an instant connection. I remember the exact moment I saw her for the first time. Shelby and I had some mutual friends, and we met up right before the tough Mudder in Austin. She was so confident, strong and fearless, I've always loved that about her.
"I love her too. I would do anything for her."
"I know you would, I've never doubted that for even a second. That's why I can imagine this has been so hard for you guys."
"What? What's been so hard for us?"
"This," She stated and wrapped her hand around my penis. "You're so much smaller than daddy, and - well - I know we've both always thought about that day, she's always expected the guy she fell in love with would have a cock more like daddy's."
My heart fluttered and mind raced, was this true or was Kat teasing me or just being a bitch?
"Which is why I am so happy this has happened, for both of you... all of us."
"You're happy I broke my arms?"
"No... well, not really that, but that the whole thing. Shelby finding out you love being teased about your little dick, that you enjoy watching girls get fucked by bigger and better cocks, that she finally realized how big a crush you've had on me." She smiled looking right at me.
"You... you've known?" I stuttered.
"Of course, you think I can't tell when a guy is into me?" I felt a blush wash over me, somehow her knowing my feelings was more embarrassing than her seeing me naked.
Kat got up and led me by the dick like a dog on a very short leash to the toilet, where I sat and urinated, and I realized I was getting used to the routine. As soon as I finished, she left the room leaving me alone. I stumbled back to the bed and laid down.
