Sister’s Hypnosis Game

Disclaimer. All characters are 18+ in this story

My name is Theo a 26 year old guy and this is a wild story that I wouldn’t have believed it it hadn’t happened to me.

Before I get into details though I think adding some background and context is important. I had recently gotten engaged to a wonderful woman Claire that I had met while we were both at college and we have now properly started to plan our lives together. We are im full wedding planning mode as we plan on getting married in the summer.

I have one younger sister Britney who is 18 and still in high school. When we told her about the engagement it was like a weird looked had passed over her face before she had congratulated us and she had soon rushed off to her group of friends.

Now it is important for the story to mention Britney and her friends. They are a group of five girls that have been friends since early primary school and I knew all of them well enough. And it seemed obvious that when they went to high school that all of them became cheerleaders. All fit and slim bodies that makes guys drool whenever they arrive anywhere and they knew it as well. My sister is the ring leader of the group. A petite blonde with B cup tits and short at 1.4m, she would be the shortest in the group if it wasn’t for Tiffany that is like a centimeter shorter also with blonde hair and B cup tits. They have often been mistaken for sisters or twins when they go out looking very similar to each other.

Then there is Nicole who is the tallest in the group at 1.85m she is almost as tall as me but she is slim and flat. She only has A cups and loads have joked she shouldn’t be a cheerleader with the others but play aome of the sports herself but she wants to stick with her friends. Jessica is a brown haired girl that is a little taller than my sister but has the biggest tits in the group with a full C that makes me wonder at times if she isn’t a D. Last is Scarlett, a fiery red head standing at 1.6m and just as flat chested as Nicole.

Through the time I have know the girls they had all dated off nd on with some longer than others and I was sure that none were virgings anymore. I had even wondered during a sleepover or two if they might be bi as I was sire some experimentation happened during those nights. I also had a strong suspicion that through the years at least some of them had a crush on me at some point or another being an older guy around them. But that didn’t bother me anyway as my focus had been on Claire anyway.

Now back to the story. After telling Britney about our engagement and she running off I didn’t hear from her for a few days. That is until one evening we were alone at home. I has at home collecting some of my things and my parents were working late. As I was loading things in my car Britney asked if I can help her in her room and like any good brother I couldn’t say no to my sister.

As I walked in she was in a smallish skirt and tight top and with how I could see her nipples it was clear she wasn’t wearing a bra. As I came in she seemed giddy and soon was asking me if I can help her practice for their school talent show as she wanted to do a last one now in her final year. I agreed without even asking her what she was planning on doing. That is when she told me she wanted to do a hypnosis act but needed to practice to put someone under.

I was skeptical to say the least but I sat down as she instructed and told her that she can try it. She pulled out one of the amulets that she has and sometimes would wear and started to swing and chant. I was still thinking it would fail for sure when things started going darker.

I can’t tell you what happened but as I blinked my eyes I looked at Britney sitting in front of me. I stood up from the bed and started doing a weird ballerina dance for Britney. Finally sitting down again on the bed with her and asking how it was. That is when things seemed to go darker again.

The next time I open my eyes and see Britney in front of me I start smiling brightly. So glad that this gorgeous high school cheerleader is my girlfriend and only mine. I lean forward and give her a soft kiss on the lips.

“So Babe are you serious. We can finally fuck, you know how long I have waited for you to say you are ready. The wait will be worth it though babe since now you are safe and we can fuck with no worries about you getting knocked up”

I kiss her deeper as out tongues play together. Still in awe that I am dating this amazing girl. Lifting her top off and seeing her perky B cup tits. I latch onto them and lick and suck on them in turn. I feel as her soft little hands run through my hair and encourage me in what I am doing as she moans with her nipples getting harder in my mouth. I suck and nibble on them bringing more moans from her as I do.

Finally I lift my mouth from her hard and wet nipples and push her down on her back. As she lays back her tiny skirt rides up and exposes her tiny pink pussy between her legs. Seeing even more as she spreads her legs for me more. I see a wet glistening pussy already as I look at it hungrily. I lean down and start to lick and suck on her pussy. Just knowing that I love doing this and my girlfriend’s moans encouraging me in what I am doing. Especially when she grabs my head and pulls me even more into her pussy. Moaning and begging me to make her cum. I don’t let up and soon enough she is shaking and moaning under me and my mouth filling with her sweet juices.

As I lift my mouth she tells me to lay down so that she can suck my cock now. I do this, I get up and strip naked before laying down on her bed with my cock pointing up. She moves down and she starts licking and sucking on my cock. I can feel with her rhythm and routine that she hasn’t done this before as it is skeptical and shy and reserved. She is trying but not great at it so I try and guide her and give her instructions how to suck it better.

Soon though she lifts her head and states that she will practice more another time. She then gets up and straddles over me. Grabbing hold of my cock and lining it up to her wet pussy. She then starts to slowly drop down as she moans out. I feel how tight and wet and warm she is as my cock head goes between her lips. And as she moves down slowly it is very clear that my girlfriend really is a virgin. I can feel how her pussy grips my cock and stretches as she goes slowly down until she gasps loudly when my cock touches and pushes against her barrier that is still intact.

I watch the determination on her beautiful face as she grits her teeth and pushes down hard on my cock until her hymen breaks and she drops down even more on my cock. She gives a small scream and tries to steady herself. I hold her hips and help her to gather herself before she starts to slowly ride up and down my cock.

It doesn’t take long for her to ride me harder and grinding on my cock as she moans louder and louder. I can see her skills and stamina as a cheerleader in how good she can ride on my cock despite this being a first time fucking. Soon enough I am starting to get closer and closer and telling her that I am about to cum. Instead of slowing down though she rides me even harder and telling me to cum inside of her and fill her pussy.

I can’t hold it and grab Brotney’s hips as I pull her down the full length of my cock and start cumminh deep inside my sexy girlfriend. Shooting a huge load inside of her as I feel a second orgasm ripping through Britney’s body as she starts cumming with me, her pussy clamping down around my cock and milking all my seed into her. That is when I hear a scream of shock from the door

“Fuck Britney what the fuck are you doing. How could you fuck your own brother like that. You are fucking crazy bitch”

Both our heads turn and I see Scarlett standing in the door. Her gand over her mouth clearly in shock seeing me fucking her friend and my girlfriend but not understanding why she thinks I am her brother.

Britney jumps up and runs towards Scarlett. Her sexy tight ass shaking and I can see cum running out of her pussy and down her thighs and legs. She places a hand over Scarlett’s mouth and the lead her out of her room and closing the door clearly in a hurry. I can hear their voices clearly having an animated discussion somewhere down the hall but can’t make out what is happening but getting more and more curious.

Finally after what felt like an age the door opens and there stands my sexy Britney still naked with a weary smile and behind her standing Scarlett with more of a wicked smile and they both walk inside. Britney comes up and kisses me deeply on the mouth before she starts with an explanation. “Theo baby we have a small problem. My friend Scarlett having seen us having sex is insisting that she will tell on us unless she gets fucked by you as well. I told her that I won’t force you to do anything with her and that it will be your choice. But that if it is going to happen I will watch it all and that you will remain my boyfriend no matter what. And besides her girlfriend Nicole will be pissed if she finds out that she fucked a guy so everything here will remain a secret.”

I look between my beautiful girlfriend Britney and Scarlett who looks almost as good as my Britney but it is only my Britney that I love and want

“Babe you know how much I love you. And that is why even if you ask I can’t cheat on you. I only want you and no one else”

Britney looks a little disappointed and so do Scarlett. Britney speaks and next moment things go dark again.
