Book 2: Fill Me Up Step-Uncle

I hugged Mom and Dad goodbye at the end of the long driveway, waving until their car vanished around the bend. Mom had reminded me at least a dozen times to be on my best behavior. “Your Aunt Lauren and Uncle Ryan are doing us a huge favor letting you stay the whole break. Don’t cause any trouble, you young lady.”

I smiled sweetly and promised I would be good. Inside, though, my stomach was already fluttering with excitement. Three whole weeks in this big suburban house. Plenty of time to stop being the perfect daughter and finally be the dirty girl I kept hidden.

Aunt Lauren pulled me into a warm hug the moment I stepped inside. “Emma, sweetheart! Look at you, being all grown up, you’ve turned into such a beautiful young woman!” My cousins, little Lily and Noah, immediately swarmed me, chattering excitedly as they helped drag my suitcase upstairs.

And then I saw him.

Step-Uncle Ryan stood at the top of the stairs, arms crossed over his broad chest. At forty-four he was still built like a man who stayed strong: wide shoulders, thick arms, and his unmistakable purely dark hair that made him look distinguished and dangerous at the same time. His deep voice rumbled when he greeted me.

“Welcome, Emma. Make yourself at home.”

His eyes lingered on me a second longer, observing, who ever knows what’s on his mind. But just long enough for heat to bloom low in my belly.

That that night at dinner I played the role of sweet, polite niece perfectly; laughing at Noah’s jokes, helping clear plates, smiling at everyone. But my mind kept drifting to the locked folder on my phone full of filthy videos: older men ruining eager young girls, step-family fantasies that always left me soaked.

The next morning Aunt Lauren announced she was taking the kids with her to the family store for a big inventory day. “We’ll be gone most of the afternoon. Ryan has some work in his office, but you can use the pool or just relax, Emma. Be good!”

As soon as the car pulled away, the house fell quiet. My pulse quickened. I’d been aching since last night, imagining Ryan’s deep voice telling me what to do. I slipped upstairs to the guest bathroom, locked the door, and hiked my little sundress up around my waist. No panties. I was already dripping.

I sat on the edge of the tub, spread my legs, and started rubbing slow circles over my swollen cl*t, biting my lip to stay quiet.

Then I heard it — a low, guttural groan coming from the main bathroom across the hall.

Curiosity built through me fast. I quietly crept out, heart hammering, and tiptoed toward the sound. The door was slightly ajar. I peeked through the crack.

H*ly f*ck.

Step-Uncle Ryan stood in front of the large mirror, sweatpants shoved down to his knees. One big hand was wrapped around an absolutely massive c*ck, f*ck it was thick, thick veins decorating the edges, and rock hard. He was stroking it with long, lazy pulls, his thumb swiping over the fat, leaking head looking soft. His eyes were half-lidded, jaw tight, muscles flexing in his chest and arms as he worked himself.

I couldn’t breathe. My p**sy clenched hard, fresh wetness sliding down my thighs. He looked even bigger than anything I’d watched in my secret videos.

I must have made a tiny sound, because his eyes suddenly snapped open and locked onto mine in the mirror.

I froze.

For several long, charged seconds we just stared at each other. Then he turned around slowly, still gripping his long heavy cock, and faced me directly, with the tip pointing at me.

“Emma…” His voice was rough, and sent shivers down. “You shouldn’t be here.”

I didn’t run. Instead, I pushed the door open wider, my sundress still bunched around my waist, my bare, glistening p*ssy completely exposed. My cheeks burned with shame and arousal.

“I… I heard you,” I whispered. “I was going to touch myself… and then I saw you.”

Ryan’s eyes darkened with hunger as they raked over my body. “Your parents told you to behave. Does sneaking around and watching your step-uncle stroke his c*ck count as behaving?”

I shook my head, biting my lip. “No… I’ve been bad. I watch a lot of p**n. Older men… step-family stuff. It makes me so f*cking wet.”

He let out a dark, low chuckle and stepped closer. His thick c*ck bobbed heavily between us, the tip shiny with prec*m.

“You’re playing a dangerous game, little girl. Your aunt and cousins will be back in a few hours.”

He didn’t tell me to leave.

Instead, he reached down and tilted my chin up with two fingers. “You really want this?”

I nodded eagerly and sank to my knees on the cool tiles without being asked. “Please, Uncle Ryan… I want to feel it.”

He groaned deeply and guided the fat head of his c**k to my lips. “Then open that pretty mouth.”

I stretched my lips wide around him. He was so thick I could barely take the soft head at first. He tasted salty and masculine. Ryan gripped my hair and slowly pushed deeper, feeding inch after inch into my throat. I gagged and drooled but kept going, looking up at him with watery eyes while my hand slipped between my legs to rub my aching clit.

“That’s it,” he growled. “Suck your step-uncle’s c*ck like a good little sl*t.”

After several minutes of using my mouth he pulled out, breathing hard, and ordered me up. “Turn around. Hands on the counter. As* out.”

I obeyed instantly, bending over the sink. He flipped my sundress up, spread my cheeks, and rubbed his thick c*ckhead up and down my soaked slit.

“So f*cking wet for me already,” he muttered, then pushed forward.

I gasped sharply as he stretched me open. He was huge. Inch after thick inch sank into my tight p*ssy until his hips were flush against my as*. The fullness was overwhelming.

“Uncle Ryan… you’re so deep,” I moaned, gripping the counter.

He grabbed my hips and started fucking me with long, powerful strokes. Then he went faster, delivering short nasty rough thrusts.The wet slap of skin on skin filled the bathroom. One hand reached around to rub my cli* while the other tangled in my hair, pulling my head back so I could watch us in the mirror.

“You like getting your tight little puss* ruined by your step-uncle?” he growled.

“Yes!” I cried. “Harder… please…”

He spanked my *ss hard, making me yelp, then railed me even deeper. My legs started shaking. Pleasure coiled tight and fast inside me.

“I’m gonna cum— Uncle Ryan, I’m cumming!”

My pu**y clenched violently around his thick c*ck as I came hard, soaking his shaft. He didn’t slow down. He f**ked me through it, growling filthy praise in my ear, until his own rhythm broke.

“F*ck, Emma… gonna fill you up.”

“Yes! C*m inside me, please!”

With a deep groan he buried himself deep, to the hilt and erupted. Releasing hot, nasty, thick pulses of c*m flooded deep into my p*ssy. He kept grinding, pumping every drop into me until it started leaking down my thighs.

We stayed like that for a moment, breathing hard.

Then he pulled out slowly, turned me around, and rested his forehead against mine.

“Clean up,” he said, voice still husky. “And this stays between us.”

I smiled up at him, cum still dripping down my legs.

“Yes, Uncle Ryan… but I’m going to want more before this holiday is over.”

He smirked, his eyes already dark with intention.
