Chapter 3

The sauna was getting hotter by the minute. Sweat poured down my body, making the towel stick to my skin in the most obscene way. My nipples were rock hard, aching from the heat and from everything Mark had already done to me. My pussy was throbbing so badly I could feel my juices leaking down my inner thighs.

Mark's big hand was still gripping my waist, holding me exactly where he wanted. His other hand teased along my inner thigh, so close to my dripping slit but never quite touching it.

"Loosen the towel more," he ordered, his voice low and rough. "I want to see those pretty tits properly."

I was shaking. Part of me knew this was so fucking wrong — he was my stepdad. But the dominant way he spoke made my pussy clench hard. I slowly pulled the towel lower until both my heavy breasts spilled out completely, shiny with sweat, nipples stiff and begging for attention.

Mark let out a deep groan of approval. "Fuck, look at you. Such a good girl for Daddy."

His rough fingers traced a slow line from my collarbone down between my tits, following a bead of sweat. He circled around my left nipple without touching it, then did the same to the right. The teasing was driving me crazy. I arched my back, pushing my chest toward him, desperate for more.

"Please…" I whimpered.

"Please what?" He smirked, dark eyes locked on my tits. "Use your words, Emily. Tell Daddy what you need."

I was so embarrassed, but the words slipped out anyway. "Touch my nipples… please, Daddy."

He chuckled darkly and finally pinched my left nipple between his thick fingers, rolling it hard. A sharp jolt of pleasure shot straight to my clit. I moaned louder than I meant to. He leaned in and sucked my finger into his hot mouth first, showing me exactly what he could do with his tongue, before moving to my breast. His lips closed around my nipple, sucking hard while his teeth grazed the sensitive bud.

"Oh god…" My hips jerked forward on their own.

His other hand finally slid higher between my legs. Two thick fingers stroked along my soaked pussy lips, spreading my wetness everywhere but refusing to push inside or touch my swollen clit.

"You're fucking dripping," he growled against my tit. "Soaking the bench like a desperate little slut. All this just because your stepdad touched your tits in the stands? Pathetic… and so fucking hot."

He switched to my other nipple, biting it lightly while his fingers kept teasing my entrance. Every time I tried to grind against his hand, he pulled back just enough to keep me on edge. The frustration was killing me. I was panting, sweating, my whole body trembling with need.

Mark's towel had fallen open slightly. His thick, hard cock was standing straight up, thick and veiny, the head already shiny with precum. I wanted to touch it so badly, but he grabbed my wrist when I reached for it.

"Not yet," he said sternly. "You don't get to play with Daddy's cock until I say so. Tonight is about teasing that greedy little pussy."

He pulled me closer until I was almost sitting on his lap. His hard shaft pressed against my thigh through what was left of the towel, hot and heavy. He started grinding slowly, letting me feel every inch while his mouth worked my tits and his fingers kept edging my pussy.

I was losing my mind. The heat, his smell, his deep commanding voice — everything was too much.

Then my phone suddenly rang on the bench beside us.

It was Mom.

My eyes went wide with panic. Mark's fingers never stopped. He pushed one thick finger just barely inside me, stroking my walls while his thumb hovered right over my clit.

"Answer it," he ordered quietly, eyes gleaming with wicked amusement. "And keep your voice normal, baby. Or I'll stop."

I grabbed the phone with shaking hands and answered. "H-hey Mom…"

Mark chose that exact moment to suck hard on my nipple again while slowly pumping his finger deeper. I had to bite my lip to stop from moaning.

Mom's voice came through clearly, slightly muffled by the door. "Hey sweetie, just checking in. I'm stuck in a little traffic on the way back. You two okay in the sauna? Not too hot?"

Mark added a second finger, stretching me open while his thumb finally brushed my clit in slow circles. My legs shook violently.

"Y-yeah… we're fine," I managed, my voice breathy. "It's really… really hot in here."

Mark smiled against my breast and whispered, "Tell her you're sweating a lot."

I repeated it shakily. Mom laughed and said she'd be back soon. The whole time Mark kept finger-fucking me slowly, keeping me right on the edge without letting me cum. My juices were dripping down his hand.

When I finally hung up, I was a mess — panting, tits red from his mouth, pussy clenching desperately around his fingers.

Mark pulled his hand away just as I was about to explode. I whimpered in frustration.

"Enough for tonight," he said, voice firm and dark. "You'll stay needy like this until tomorrow at the finals. I want you soaked and desperate when I finally fuck you properly in the stands."

He stood up, his massive erection right in front of my face for a second before he wrapped the towel back around his waist. I quickly fixed my own towel, my body still trembling with unfulfilled lust.

We heard Mom's footsteps coming down the hall just as we stepped out of the sauna. My face was flushed, my legs weak, and my pussy was still aching badly.

Mark gave me one last commanding look and whispered, "Be a good girl and wait for Daddy tomorrow."

I could barely walk straight. The tension between us was unbearable now.

I needed him to fuck me so badly I could cry.
