I was eighteen, living in that small apartment above the bookstore where the walls always smelled like old paper and rain. My roommate was gone for the weekend, and Mark had come over with takeout and that look in his eyes he tried to hide behind easy jokes. We had been circling each other for months, friends who touched too long when we hugged, voices dropping when the conversation turned late. That night I decided I was ready. I told him after we finished eating, my voice steadier than my hands. He asked if I was sure, twice, and when I nodded he kissed me like he had been waiting to breathe again.
We moved to my bedroom without turning on the overhead light. The bedside lamp cast everything in soft gold. I pulled my sweater over my head and felt the air touch my skin. Mark watched, not rushing, his hands resting at his sides until I reached for him. I wanted to feel his weight, the solid press of another body. He undressed slowly, letting me see him, and when we were both bare I lay back on the sheets that still held the warmth of the afternoon sun through the window.
His mouth found mine first, then traveled lower. Every kiss felt like a question he was answering with his tongue. He spent time on my breasts, sucking gently until my nipples tightened and I arched without thinking. Lower still, he parted my thighs and settled between them. The first slow lick made me gasp. He took his time, learning what made my hips lift, what made my breath catch. I had touched myself before, but this was different, wetter, warmer, someone else deciding how much I could take. When he slid one finger inside me I clenched around it, surprised by how full even that felt. He added a second only after I whispered that I wanted more.
I came with his mouth on me, sudden and sharp, thighs trembling against his shoulders. The aftershocks left me loose and wanting. He kissed his way back up my body and I tasted myself on his lips. My hand found him, hard and hot, and I stroked him the way he showed me, learning the rhythm that made his breath hitch. He reached for the condom on the nightstand and I watched him roll it on, fascinated by the simple, practical motion.
When he settled over me I felt the blunt pressure at my entrance. He moved slowly, giving me time to adjust, stopping when I tensed. I told him not to stop. Inch by inch he filled me, the stretch burning at first then easing into something deeper. I kept my eyes on his face, watching the concentration and the care. Once he was all the way inside he stayed still, letting me feel the fullness. I shifted my hips experimentally and the friction drew a sound from both of us.
He began to move, careful thrusts that gradually grew deeper. I wrapped my legs around him, heels pressing into his back, urging him closer. The discomfort faded and left only heat and the wet sound of our bodies meeting. I reached between us and touched myself the way he had, circling my clit while he thrust, and the combination made everything tighten again. My second orgasm rolled through me slower, longer, pulling him deeper.

He followed soon after, groaning into my neck, his rhythm breaking.
We stayed joined for a while, breathing together. When he pulled out I felt empty in a way that surprised me. He disposed of the condom and came back with a warm cloth, cleaning me gently, the tenderness almost more intimate than the sex. We talked afterward, quiet voices in the dark, about what we had felt and what we wanted next time. I fell asleep with his arm around me, skin to skin, already knowing the night had changed something I could not name yet.
In the weeks that followed we learned each other more. He taught me how to ride him, how to take him from behind, how to use my mouth until he trembled. I discovered I liked the taste of him, the way he lost words when I took him deep. We experimented with positions and pace, sometimes slow and lingering, sometimes urgent against the kitchen counter before work. Every time he asked what I wanted, and I learned to answer without shame.
That first night remains the one I return to when I touch myself alone. The careful way he entered me, the patience, the moment the burn turned to pleasure. It was not perfect, but it was mine, and it opened the door to everything that came after. I still keep the memory close, the way his hand felt on my hip, the sound of rain starting outside the window, the quiet certainty that I had chosen this and it had been good.
