Step Sis, I Don't Want to Fuck You! It's Just Our Stepmom Making Me Teach You How to Use Condoms!
When our stepmom shoved a box of colorful condoms into my hands and said with a serious look, "You need to teach your sister how to use these properly so she doesn't get into trouble," I froze completely.
Standing in front of me was my freshly 18-year-old, irresistibly sexy stepsister Diana Rider. She was wearing a thin white camisole that barely contained her perky breasts, with pink panties teasingly visible. Her big, innocent-looking eyes stared at me curiously, lips slightly parted, releasing a sweet, intoxicating breath.
The Awkward Yet Extremely Arousing "Sex Education" Lesson
"Bro... do I really have to practice in front of you?" Diana Rider bit her lower lip, her voice soft and shy but laced with unmistakable excitement. She knelt on the bed with her knees slightly apart, her seductive curves looking even more tempting under the bedroom light.
I tried to stay calm: "This is just teaching. I won't actually fuck you..."
But when her delicate hand wrapped around my already rock-hard cock and slowly rolled the first condom down my shaft, the silky touch and her focused, cute expression nearly made me explode instantly. Every time her fingers brushed over my sensitive head, it sent electric shocks through my entire body.
Diana Rider's Seductive Demonstration
She learned quickly — and very "enthusiastically." From regular condoms to ultra-thin, ribbed, and delay types, she tried them all. After sliding each new one on, she would look up at me with those expressive eyes and ask softly, "Is this correct, brother? How does it feel?"
The moment she put a condom in her mouth and used her lips to roll it down my throbbing cock, I completely lost control. Her warm, wet tongue swirled skillfully as her mouth enveloped me, creating the most obscene, wet sounds. The room was filled only with our heavy breathing and the sound of condom wrappers being torn open.
"Stepmom said... we have to do it for real to learn properly..." Diana Rider gasped as she slowly lowered herself onto me. Even through the thin latex, her tight, dripping pussy felt incredibly hot and gripping as it swallowed every inch of my cock.
From "Lesson" to Completely Uncontrolled Taboo Passion
The so-called "condom tutorial" quickly turned into pure, forbidden lust. We went from the bed to the bathroom, then to the living room sofa. Diana Rider came again and again, moaning "brother" while her body honestly met my increasingly deep and rough thrusts.
Her smooth skin flushed pink, sweat trickling down her collarbone, her hard nipples standing erect from overwhelming pleasure. In that moment, I completely forgot this was supposed to be just a lesson.
