My name is Jenny and I am 5'1, 95 pounds, blonde hair, blue eyes, 36 A cup. One day while I was walking past my sister's room, I heard her moaning, so, wondering what was up, I looked through her key hole and saw her laying on her bed with a vibrator in her pussy. Now my sister is 17, 5'10, about 125 pounds, also blonde hair, blue eyes, and she has pert 36 C's. I slowly and quietly opened her door and walked inside, I got to the side of the bed and cleared my throat. "What the hell are you doing in here?!?!?!?" she screamed, still having the vibrator deep inside her. "I heard you moaning, and was wondering what you were doing." I said softly, sitting on the side of her bed. "Get the hell out of here you little dyke!!!!" she yelled at me. "Come on sis, I want to try, does it feel good?" I was getting wet sitting there looking at her beautiful tan body, naked before me. She was sweating, and little beads were falling down her breasts onto her stomach, and the small patch of pussy hair above her mound was damp and matted with her sweat. I could smell her arousal in the air. I was dressed in just my night shirt, no panties, I never wore them. My sister looked at me quizzically for a moment, then got a sly smile on her face. "If you make me cum with my vibrator, I will do the same for you, ok?" "Okay, but I really don't know what to do." "Just move it slowly in and out and lick my clit, but be gentle." I got between my sister's legs and took the vibrator from her, I started moving it in and out of her sopping wet pussy, then I bent down and tasted her juices, this was my first taste of pussy, and I was in love. I licked her slit and all around the dildo and sucked her clit into my mouth, driving her wild, I then removed the vibrator and replaced it with my tongue, I ate her like a pro, quickly bringing her to climax, she started to shudder and her body went stiff, her pussy spasmd and my mouth was filled with her girl cum. I held her as she came down off her orgasm, smiled at her and said softly, "my turn sis." She kissed me, and for the first time I felt a tongue enter my mouth, we kissed passionately, and she removed my night shirt. She kissed her way down my neck to my small breasts and started sucking on my nipples, my breath was coming in short gasps and I was moaning loudly. She then moved down my stomach to my naval and started tonguing my belly button, this drove me wild. She slowly kissed her way down to my shaved pussy and started to lick me softly, tenderly. She kissed my pussy, then licked my engorged clit, I grabbed her hair and pushed her head harder into my pussy, she took the hint and started giving me a good tongue lashing. She licked every part of my pussy, driving me wild. I bucked my hips in rhythm with her tongue. Then she did something I didn't expect, she licked her finger and pushed it into my pussy, it hurt for a second, then felt really good. She then inserted and second finger and started moving them in and out while sucking on my clit. She was driving me wild!! She quickly brought me to several orgasms and we fell asleep in each other's arms, totally naked.
