I walked into the small apartment for my first "sex education" session, knowing exactly what it was. The guy waiting for me was older, built like he lifted heavy shit for a living, and he didn't waste time on small talk.
"Strip," he said, leaning against the kitchen counter. "Show me what we're working with."
I pulled off my clothes right there in the middle of the room. No teasing, no slow reveal. He wanted to see my tits and my shaved pussy, so I gave him that. My nipples were already hard, and my cunt was starting to get wet from the way he stared.
He stepped closer and grabbed my left tit, squeezing hard. "Decent. Now get on your knees and open your mouth."
I dropped down.

He unzipped and pulled out his thick cock, already half hard. It smelled like soap and man. I opened up and he pushed it straight in, no warning, sliding over my tongue until it hit the back of my throat.
"That's lesson one," he growled. "Suck it like you mean it. Use your tongue on the head and take it deeper every time."
I did what he said. I bobbed my head, getting it sloppy fast, spit running down my chin onto my tits. He held the back of my head and fucked my face in short thrusts, making me gag when he went too far. My eyes watered but I kept going. My pussy was dripping onto the floor by the time he pulled out.
"Stand up. Bend over the table."
I did. He kicked my legs apart and rubbed his wet cock between my ass cheeks before lining up with my hole. One hard push and he was inside me, stretching me open. I moaned loud because it felt fucking good.
He grabbed my hips and started pounding. No slow build-up. Just deep, rough strokes that made my tits slap against the table and my ass ripple every time he slammed in. The wet sound of his cock driving into my cunt filled the room.
"Fuck, you're tight," he said. "Clench on it. Show me you want this lesson."
I squeezed my pussy around him on every thrust. He reached under me and rubbed my clit in quick circles, making me push back harder against him. I came first, legs shaking, cunt pulsing around his dick while I cursed and begged him not to stop.
He didn't. He kept fucking me through it, then pulled out, spun me around, and shoved me to my knees again. "Open your mouth. Lesson two is swallowing."
I stuck my tongue out. He stroked his cock twice and shot thick ropes across my tongue and lips. Some hit my cheek. I swallowed what I could and licked the rest off his head when he pushed back in.
We did it again later that night on the couch, me riding him while he slapped my ass and told me how to grind my clit against him. By the end of the night my thighs were sticky, my throat was sore, and I knew exactly how to ask for what I wanted.
He sent me home with instructions to practice on my own fingers and come back ready for anal next time. I already couldn't wait.
