Yes

"Fuck it" I said.

My hand went to my pussy. I began to tease myself. I was already getting wet and pretty soon I could feel my arousal. I eased a finger into myself. It felt good but I needed more. I pulled my finger out and only to press another 2 into my core.

I opened my eyes. The sight of the boys cocks straining against their boxers got me even more aroused.

"This is so hot…" I panted. I couldn't believe my sister and I were both fingering ourselfs in front of 3 horny boys.

I heard my sister moan again. God, this was getting hotter all the time. I was actually getting turned on by my little sister. This wasn't the first time I'd had thoughts about her. It was impossible not to, the way we paraded ourself around the house in the buff. I bet she thought about me too.

She imagined me catching her masturbating one too many times. I'd stroll over to her bed as she lay there quivering. I'd tell her that I was gonna tell mom everything. She begs me not to, she'll do anything. Anything? I ask as I climb on top of her. She looks into my eyes. I can tell she's uncertain. We can't! She tries but she cut off as our lips meet and I kiss her deeply. She struggles for a moment but as she feels my our body's press against one another and our sex's collide briefly before I press our hips firmly together. We explore each other's bodies and soon we're moaning in unison. This is so wrong, she says, don't stop. I can feel she's getting close and I can feel my self getting close too.

"Oh, Lucy" I moan out loud.

I was woken from my fantasy by the sound of excited giggling.

"Something you want to tell me sister?" I noticed she put extra emphasis on the last word.

I stayed quiet feeling embarrassed. I felt flushed but I guessed that was probably from arousal rather than embarrassment.

Lucy moaned again. It really turned me on each time she moaned but I knew that she was getting close now. Her noises were becoming more frantic and strained. I did not want to be stuck with what ever forfeit they came up with. I had to cum fast.
