My step-sister Chrissy and I started fooling around with each other senior year (see parts 1 and 2). I had masturbated for her then we both masturbated in front of each other.
Friday evening we have dinner with my mom and Chrissy's dad to discuss weekend plans. Then the 'rents went out to see some band we had never heard of. Chrissy and I had the house to ourselves. We decided to watch a movie on our parents new VCR. We watched An Officer And a Gentleman and got kinda fired up. As we were watching the movie, we were fooling around. We were both wearing athletic shorts and t-shirts.
We were sitting side-by-side on the sofa. First I rubbed my bare leg against hers. Chrissy reached over and held my hand for a while. Then I started running my fingers gently up and down her bare legs. In the early '80's both men and women wore short shorts. Slowly my fingers went to the insides of her leg. Then up under her shorts. When my fingers traced the edge of her panties, Chrissy moaned and goose bumps swelled out on her arms.
I went further and began running my fingers over the front of her panties. I could feel the heat of her labia as it swelled under my gently stroking fingers. After a few minutes Chrissy started breathing heavily with her chest rising and falling. Her nipples stood out and then I felt her panties getting wet. Chrissy leaned over and whispered in my ear, "That feels so good! You are making me crazy." Richard Gere and Debra Winger were making out on the screen to add to our excitement.
Chrissy turned my face and kissed me on the mouth as her hand went to the inside of my thigh then up inside of my shorts. This could not have been more erotic. Here we were kissing and rubbing each other under our shorts and over our underwear. I was soaking my undies with precum and she was soaking her panties with poontang. As we kissed I moved my hand up and felt her tits over her shirt and bra.
After we made out for a while, Chrissy said, "I have to use the restroom." She got up and came back a few minutes later. She climbed on top of me and sat on my lap facing me. She kissed me again and I put my arms around her. As we kissed and I ran my hands over her back, I noticed something hand changed. NO BRA!
I ran my hands around to the front and got two hands full of Chrissy's tits. Mmmmmm - big, pillowy, smooth, nipple topped Chrissy tits. We kissed as and I ran my hands over her tits and gently pinched her nipples. I grabbed the bottom of Chrissy's t-shirt and started pulling up. She reached her arms up and I pulled the shirt up and off. Ohhh flesh. I buried my face in her tits. I kissed her tits and gently sucked on her nipples. Chrissy was clearly loving this as she rubbed her hands in my hair and pulled me into her tits as I sucked her tits with more vigor.
Although I was having a great time, I wondered what else she had taken off. I ran my hand down and under her shorts. NO PANTIES! Oh Heaven. I stood and, with Chrissy clinging to me, turned and laid her on the couch. I grabbed her shorts and pulled them down. I rubbed my fingers up and down her pussy until I found her vagina (female anatomy is rather confusing if you have never been there before). I put my middle finger in her vagina and stroked. (Oh my God, her vagina was so tight; one finger barely fit.) Chrissy went off like a rocket. Her hips thrust up, she got amazingly wet and her eyes rolled back. I was going to kiss her but her mouth was open so I started sucking her tits instead.
As I fingered Chrissy and sucked her nipples (back and forth), I remembered her masturbating for me and when she ran her fingers rapidly over her clit - that is when she orgasmed. So I removed my finger from her tight twat and started running three fingers rapidly over her clit. That did it. Chrissy's eyes squeezed tight, she thrust her hips up and stayed in that position. A high shriek came from her throat, and her entire body convulsed.
Wow. Giving another person an orgasm is truly amazing.
