Tuesday, we made a big step forward

We were alone that evening. Just the two of us from 7pm to 1am. I had been sitting with Anna in the couch casually watching TV. Except she was topless and I was naked, with only my chastity lock and a plug up the ass. We were watching a girly TV show, but I couldn’t concentrate on anything else that the fear of having visitors, and my sister’s breasts bare naked for me to admire.

Then she switched to a video. A porn scene between two lesbians, one licking the other’s pussy. Anna turned towards me.

“You’d like that, wouldn’t you, sis?”

I stopped thinking. What was she saying?

“You know I’ve been feeling very horny this weekend, and Mike being away and all… It’s unsatisfactory. I was wondering with what dildo I was going to fuck myself with tonight, but then I remembered I had someone to do it for me, without it being cheating. And then, when I watched this video I thought it looked so pleasurable… Don’t you think?”

Without adding a single word, she got up and slowly walked to the stairs. I followed her, hoping it wasn’t another trick, and we arrived in her room. She handed me the same blindfold as yesterday.

“Of course, you can not look at it. I shaved myself clean so I’m clearly to pretty for your standards.”

I was going to lick her. My sister. And make her cum? Would she let me? I just put on the blindfold and heard her undress. She guided me to the bed, where she sat, and brought my face in the warmth emanating from her thighs and pussy.

“Come on, sissy. Pleasure your Mistress.”

“Oh yes!”

I licked. A girl’s pussy, for the first time in my life. My sister’s pussy. Oh god this was so perfect. I loved her. I worshipped her. She tasted so good I couldn’t help but go faster and faster, licking and sticking my tongue in, kissing her lips, circling around her clit. She was immediately into it, moaning loudly. Her grip was tight on my head, confirming her pleasure. I dared touching her legs, so soft and thin.

“Oh yes, right there, sissy! Ooh Selina you’re such a good ****! Make me cum, bitch!”

She was panting on those words, and I gave all I had at that moment. She came hard, pushing my face into her and thightening her legs on my head. I felt all the spasms running through her body, showing me how good it had been. At the end, Anna asked for more.

“You’re gonna do it again. And this time I sit on your face.”

I laid on the bed and quickly felt her wet vulva on my lips. I licked her again, this time allowing my hands to grab her thighs. She didn’t mind it. She was grinding on me just like she would have done on a pillow. And it didn’t take long before she came again, her grunts of pleasure echoing in the whole house.
