5 — PRIVATE TUTORING (IV)

EMMA

I slipped into the university library after hours with my heart beating so fast it hurt. The big room was mostly dark. Only a few security lights glowed soft and yellow between the tall shelves. The air smelled like old paper and dust. My simple dress brushed against my bare skin underneath. I had worn nothing again, just like he wanted.

Marcus waited near the back, between two long rows of forgotten books. He looked calm, but his eyes were dark when he saw me.

“You came,” he said quietly.

“I said I would,” I whispered back.

He took my hand and led me deeper between the shelves until we reached a heavy wooden study table. Books were stacked on one end. He turned me around so I faced the table and gently pushed me forward until my chest rested on the cool wood. My bottom stuck out toward him. The dress rode up on its own.

“Stay still,” he said, voice low. “Tonight I’m taking something new.”

My stomach flipped with fear and want mixed together. I knew what he meant. He had promised it without saying the words. I heard him open a small bottle. Cool liquid dripped between my cheeks. His fingers spread it carefully around my tight hole, then one finger pressed against me there.

“Breathe,” he ordered softly. “Relax for me.”

I tried. His finger pushed inside slowly. The stretch felt strange and full. I bit my lip. He worked the finger in and out, adding more of the cool liquid, then a second finger. The pressure grew. It burned a little, but he went so slow and careful that the burn turned into something hotter.

“You’re doing so well,” he murmured. “This tight little ass is going to take my cock tonight. Tell me you want it.”

“I want it,” I whispered, face pressed to the wood. “Please. Just… go slow.”

“I will.” He pulled his fingers out. I heard him open his pants. Then the thick head of his cock pressed against my prepared hole. He pushed forward with slow, deliberate pressure. The stretch was bigger than his fingers. My eyes watered. I bit my lip harder.

“Breathe, Emma. Push out a little. Let me in.”

I did what he said. Inch by inch he filled me. The fullness was overwhelming. It felt like he was everywhere. When he finally bottomed out I tasted blood from biting my lip so hard. A soft broken sound escaped me anyway. It sounded too loud in the quiet library.

“Shh,” he whispered, one hand stroking my lower back. “You’re taking all of me. Such a good girl. How does it feel?”

“So full,” I gasped. “It hurts but… it feels good too. Don’t stop.”

He stayed still for a long moment, letting me get used to him. Then he started to move. Slow, controlled thrusts. Each one filled me completely. The wet sound of the lube and our bodies seemed dangerously loud between the tall shelves. Every quiet moan I made made my face burn with fear that someone might hear.

“You feel so tight around me,” he said, voice rough now. “This ass was made for my cock. Tell me how much you like being fucked here for the first time.”

“I like it,” I whimpered. “I like how full I feel. Please… harder.”

He gave me a little more. Still careful, still controlled, but deeper. The pressure inside me built in a way I had never felt before. It was different from when he fucked my pussy. Deeper. More intense. My clit ached even though he wasn’t touching it. My fingers gripped the edge of the table.

“You’re going to cum just from this,” he said. “From my cock stretching your tight little hole. I can feel you getting closer.”

He was right. The overwhelming fullness pushed me higher and higher. Every slow thrust dragged against something that made sparks shoot up my spine. I bit my lip again to stay quiet. Tears leaked from my eyes. The pleasure and the stretch mixed until I couldn’t hold it anymore.

“Marcus—” my voice broke.

“Cum for me,” he ordered softly. “Cum while I fuck your ass in this quiet library.”

The orgasm hit hard and deep. My whole body clenched around him. I had to press my face into my arm to muffle the broken cry that tried to leave my throat. Waves of intense pleasure rolled through me from the fullness alone. My legs shook. He kept moving through it, slow and steady, drawing it out until I was soft and trembling under him.

Only then did he let himself go. His thrusts stayed controlled but deeper. He buried himself all the way and came with a low, quiet groan, filling me with hot pulses. I felt every one. For a long moment he stayed inside me, breathing hard, one hand gently stroking my back.

Slowly he pulled out. The empty feeling made me shiver. I stayed bent over the table, too wrecked to move. Then I felt something soft and warm. He cleaned me carefully with a cloth he must have brought, gentle and thorough. The tenderness after the intensity made my chest tight with emotion.

He helped me stand and fixed my dress. My legs felt weak. He cupped my face and wiped a tear from my cheek with his thumb.

“Graduation is only days away,” he said, almost casually, but his eyes were serious. “You’ll leave this university forever soon. Before that happens I intend one final lesson. Something that will stay with you long after you walk across that stage.”

My heart raced again. “What kind of lesson?”

He leaned close so his mouth almost touched my ear. “You’ll find out when I call for you. Be ready, Emma. And don’t forget how well you took me tonight.”

We slipped out past the security lights into the cool night air. My body still pulsed with the new stretch and the memory of how full he had made me. His quiet promise followed me home like a second heartbeat. Graduation was coming. One final lesson. I already knew I would show up for whatever he decided I needed next.
