I'm 16 and have two younger sisters, Jamie and Becky. Jamie is fourteen and Becky is thirteen. One night our parents went out late --like always -- and my sisters and I were home alone. We started flipping through some channels on TV (it was about midnight) when we came to a porno on HBO. Now, I had seen porn before, but I don't think my sisters ever had. They just stared, yes wide, at the TV -- I saw their mouths hang open at the sight of two girls pleasing one guy. He was fucking one while she ate out the other. It was great. I was instantly hard as a rock, and Becky noticed.
'David, what's with you?' she asked, staring at the large bulge at my crotch.
'He's just horny,' Jamie said. 'Because of the TV.'
'What do you do when your horny?'
'He probably jacks off, right?'
I smiled. Becky and Jamie looked at one another, then at me again.
'Do it,' Jamie said.
I took off my pants and boxers, and revealed a rock hard cock. I began to slowly stroke it while watching the porno.
'You guys have to masturbate too,' I told them.
'Okay,' they said, and instantly their clothes were off.
I was amazed at the sight of their hairless pussies and Jamie's budding breasts. She was a little advanced for her age, but Becky was still mostly flat. They startled playing with their little cunts, and before I knew it, I was helping them. As I lay back fingering Jamie, she lay back stroking me. With my other hand I started to finger Becky, who was playing with her own tits. Then, I finger-fucked Becky until she came all over my hand. Then I decided to finger-fuck Jamie. Her pussy was so sweet! Finally she orgasmed on me. It was great.
For a while we just laid back and giggled and held and touched each other's naked bodies. We never had sex--that's pretty wrong--but we do hold our little masturbation parties every chance we get. Sometimes I just watch them do it, or they'll watch me. That's fun too. We also watch porn together while we do it. Once we all masturbated to a sex tape we found of our parents! Our cousin Samantha is coming over in about a week. She's fourteen also. Can't wait to introduce her to our little bit of fun!
Maybe I'll post some more experiences.
