She wanted to watch me masturbate

Anna took me by the hand and helped me walk to my bedroom. I didn't dare to take away the blindfold, but I couldn't resist the urge to look at her. I raised my head to see watch through a thinner part of the fabric. She was just wearing a towel. around her waist, and even from the back I could see her breasts swinging. I could barely see a piece of it, but it was still turning me on.

I lowered my head again when entering my room. She closed the door behind me and told me to sit down. I heard movements of clothes next to my drawer. She was going through my secret clothes. When she removed the blindfold, my jaw dropped at her sight. She was wearing my best outfit, black lingerie that was barely covering her most intimate parts. The bra was so small and tight around her breasts. The looked so soft. And the panties making little bulges around her sexy hips.

"I know you love what you see, sis'... I kindof enjoyed reading your fantasies about me on your blog, a few months ago. You just didn't picture what would really happen. So here's your motivation to let me see what I want. It's been a while since I've been wanting to make you my slut. So I want you to masturbate for me with your best toys. But there's a twist... You don't touch your little thing there... You will cum with your boipussy. Because that's what you really like, right ? You were saying on your blog the other day that you were still dreaming of cumming just from having your ass filled. I think my presence will definitely help you."

Was there any chance I could escape that ? And did I even want to get out of that situation ? I just stopped thinking and started doing my things as if I was alone. Apart through the webcam, nobody had ever watched me do that. So I couldn't hope for a better public than my sister for a first time. I was already harder than ever, and barely able to stand because of my excitement.

I took a butt plug and positionned myself, legs and butt wide spread, almost lying on my side. I started licking and sucking my favorite plug, the silver one with a pink diamond at the end. I didn't need any lube. I just put it against my ass, and gently pushed it inside. It went in easily as usual. While I was playing with it, taking it out and plunging inside again, my free hand was gently stroking my nipples and belly. I was feeling extatic, my feelings so exalted I was shaking.

I wanted to put a cock ring. I knew Anna didn't want me to touch my cock, but I knew she would enjoy knowing my orgasm would last longer. I had talked relentlessly about it on my blog, and if she was reading it all, she knew how intense and at the same time unbearable the sensation would be. I had tried many times to stop jerking off while cumming, but I never truly achieved it. I couldn't help but stroke it again to finish.

Anna didn't stop me when I took out the cock ring from my drawer. I passed it under my balls and then let it squeeze me. I loved that sensation. It instantly drove me far towards the orgasm. I knew if I actually touched myself I would cum right away. But I was forbidden to do so.

I grabbed the tentacle-shaped dildo. I sometimes put fake (or real) cum inside it and fucked myself until it was all in my ass, so that I could feel it pour out of me, like a whore who have been fucked by too many guys she would overflow with thick cum dripping between her legs. I loved that idea.

I got on all four, my boipussy fully opened towards my sister. I started fucking myself with the dildo. The beginning was easy to take, so I pushed it until I felt all the suckers of the tentacle spreading me apart. My cock was twitching on its own. I tried looking at Anna between my thighs, my head upside down, but I couldn't see her very well. When changing position I knew she was going to love that. I just lifted my butt above my head, my cock pointing down towards my face, and I started pouding myself with the dildo. The cockring was squeezing me tight. I was on the edge.

Anna came closer, her knees around my head. She put her fingers under the lace of her panties and pulled on them to **** the fabric to take the shape of her pussy. I could almost see it through. And it was enough. My cock started shaking. A first drop of cum landed on my cheek. Then another on my lips. The overwhelming sensation of a long orgasm was taking over me. Burning slowly inside me, without being able to let it explode for good. Twenty, fourty seconds during which my cock let out spurts of cum all over myself, while my ass was tightening around the tentacle dildo at every drop of cum coming out. My sister was laughing. I was just amazed by the view and paralyzed by the orgasm. It was the most incredible one I've ever had.
