My adoptive sister taught me how to touch her pussy

(Everything is fiction, please don't think what really happened)

It all started when a family adopted me 10 years ago, I was 8 years old and I had no friends, but I met my adoptive sister: Lily, since I saw her I fell in love, but my dirty thoughts about her began until I turned 15, I remember spying on her in the shower, or when she dressed, sometimes I saw her touching that perfect pussy she has but that was all. Until one day, I opened her door without knocking, and there I saw her: with her perfect body touching her pussy and moaning softly, she had her legs open and her eyes closed, slowly rubbing her pussy and her nipples too. I silently closed the door and saw her, she hadn't noticed that I was there until she opened his eyes. "Adrián, what are you doing here?" She asked scared covering her little body with the blanket "Let me touch you" I spoke nervously, I had never touched a pussy before "What? No! You are my brother" I saw her eyes full of fear but at the same time of desire, "then teach me, teach your older brother how to touch a pussy, Lily" She stood still and a few seconds passed before she settled down and called me to her bed, I quickly settled down and she sat astride me "no one can know this Adrián, it's just a small class about how to touch a woman okay?" I nodded and was hypnotized when she took my hand and took it to her wet pussy, it was filled with a transparent liquid and I could smell the proof of her desire in the air. Before I could continue thinking, Lily began to move and while she used my hand to cum she rubbed against my hard cock, closed her eyes when moaning and opened her mouth, "put your fingers in me, Adrian" without even her having to repeat it, I put 2 fingers in her pussy and she screamed, she began to move faster and put her hand between my pants masturbating hard and fast, I began to move my inexperienced fingers, the only thing I could think about was her perfectly shaved pussy in my hand and in her small hand touching my cock, "you're making me very wet Adrián, don't stop" Lily spoke with her voice full of desire. When I felt her pussy contract I didn't stop and I began to rub her clitoris at the same time that I put my fingers in her, I took her nipples in my mouth and she began to move desperately, my cock swelled and her moan mixed with her orgasm was what I needed to cum in her hand and in my pants, Lily and I breathed hard and I took out my fingers to put them in her mouth and she savored herself, she sucked my 2 fingers in her little mouth and then, I made her suck my semen from her hands. I hope to have classes with her again.
