Sunday, Mike made me a surprise as well

After such an incredible experience, I was unable to get out of bed, remembering every moment of the past night. Getting the collar, licking my sister, watching her getting fucked, being deflowered by Mike, being released of my cage, letting him cum inside me, sucking his cock, then fingering my sister while he was fucking her ass, before cumming in her and letting all his semen drip on my face.

Summarizing the night like this seemed like so much new things had happened to me. I had spent all morning jerking off to these memories, and wondering how Anna would treat me now. From what I understood, Mike wasn’t aware of how far we had taken our incestous relationship. He had arrived only after I had licked Anna’s pussy, and he wasn’t in line to see my hand finger her last night.

I wanted to go over her room without even knowing what I would do there. Mike was still there, but I couldn’t hear a thing. I stepped out of my room and listened quietly. I could only tell that Mike was being insulting - in a hot sexual way - to my sister, who didn’t want to do something. Anal again? I was jealous. I wanted to be there with them. They kept talking but there was no way to get turned on by the muffled sounds getting through the door. I went back inside my room without closing the door entirely, so I could have a peek to who would be passing by.

It was 11am, and our parents would be back from the groceries pretty soon. I heard louder voices coming from Anna’s room, before her door opened. I had the impression that something was off between them. I saw Mike passing in the hallway, then closing the bathroom door. My mind was wandering when he came back silently to open my own door. He walked in quietly, and only stopped next to my bed. He was only wearing shorts, and I could tell from the growing bulge inside that he was not wearing anything else. His face was saying it all. I put away my blankets, revealing my yoga pants, and knelt at his feet. He let down his only piece of clothe. The sight and smell of his erection made me instantly hard. I grabbed it without hesitation, and proceeded to lick it lovingly, making it all wet before I started sucking it. He was whispering dirty things the whole time about how good of a cocksucking sissy I was, how slutty I looked with my cock-craving-face, like I was truly worshipping his member. Once it was all sloppy, I deepthroated him all the way before he grabs my hair to make me pull back.

“Show me how much you enjoy it” he said while jerking off to my girly face. I stuck out my tongue like a good pornstar, and he came in my mouth, squirting every drop of semen on my tongue.

“Don’t tell her that, but you suck cock better than your sister. And I can see you fucking like doing it, bitch.” He was panting, clearly satisfied with my performance, but still went back to the bathroom immediately.

The day went by and sister went out with her boyfriend during the afternoon. Soon after they came back in the evening, I received a text from an unknown number.

“Tell Anna youre leaving. Dress up and stay quiet in your room. Mike.”

I didn’t care whether it was a trick or not, I just obeyed and pretended to go out, which seemed to please my sister. I thought she wanted some one-on-one time after yesterday. I waited around 30 minutes before receiving another text asking me to come in silently. I found the door already open, and stopped in front of a marvelous view. Anna was lying on the bed, wearing black lace stockings and a corsage, her hands tied to the headboard, and on top of it all, a blindfold on her eyes. Her pink pussy lips were glittering with her juices, and she was panting.

Without a noise, Mike closed the door behind me, his hard cock wiggling around. I couldn’t help the urge to grab and stroke it a bit, before he showed me what he was expecting of me. But I already knew. My boner was raising up my skirt and I was biting off my lower lip. She was right there, spreading her legs the same she was making me do, and I could have her. She would find out at some point, but I didn’t care. I couldn’t think of anything else than her hot body squirming in front of me, just waiting to be fucked.

I leaned over her, placing my hands on the mattress to prevent her from recognizing hands other than Mike’s. So close to her face, she seemed even more beautiful than usual. Seeing her in such a submissive position was putting her whole behaviour into perspective. And that was it. I rubbed the tip of my cock around her lower lips before pushing in. It was wonderful. Not so much the actual sensation than the fact that I was finally fucking my own sister. Her smoking hot body all tied up for me, and she wasn’t even aware of it. I started thrusting in and out and she started moaning. I let myself have a taste of her pretty nipples and her body reacted even harder. Writhing under my cock, she was letting out soft repressed moans, unable to quicken her pleasure.

Mike was jerking off with one hand, and groping my ass with the other. He started fingering me as I was pounding Anna harder at every thrust. I could barely mute my own pleasure. This was all so good. I was just waiting for the moment of truth to come around, and Mike knew it. He unlocked the cuffs, and sister brought her hands around me to press her body tighter against mine, her high-pitched breathing going even faster. Right then, her blindfold came off.

She didn’t speak, but her face was saying it all. Surprise, anger, guilty pleasure, embarrassment. I kept fucking her deeply and even kissed her while looking her right in the eyes. I could feel that Mike was enjoying that moment a lot.

“No! No!” Anna said. She couldn’t be too loud or our parents would hear. Her hands were pushing me away, but at the same time her hips were moving along with mine, and her legs tightening around my waist. Her screaming sounded more like sexy moans. I kissed her and she kissed me back, muting her own protestation half-willingly. I was close and so was Mike.

“I saw the video where Selina as licking your cunt until you cum, bitch. Don’t say you didn’t want it, ****-slut.”

This was the perfect ending. Without breaking the kiss, I buried myself deeper than ever inside Anna, cumming inside the pussy I desired for so long. Mike was cumming on our faces, letting out the manly grunt showing his domination on both of us. Spurting all my semen inside my sister and making her orgasm from it, while exchanging a passionate kiss full of her boyfriend’s hot cum. I was in love with that moment.
