You do what she says.

Your Girlfriend can’t wait for you to finally get healthy. The 10 days feel like forever, and your dick is aching to get some touch. With your sisters advice, your anniversary will happen on the 10th day exactly. Your girlfriend wouldn’t wait any longer anyway, she is very excited. You hear rumors that she told all her friends about how excited she is to finally have sex with you. This night must be magical.

As promised to your sister, you tried to imagine that scene in your head as often as possible. How you almost penetrated her. How you came prematurely. That feeling, when you erupted onto her belly while she laughed at you. You couldnt do it as often though, because somehow, no matter how oft you thought about it, it didnt seem to rewire your brain as your sister promised. In fact, it just seemed to make you hornier. You started to question your sisters methods. Then again she’s your sister. You trust her. Girls know these things.

The night is here. The whole afternoon you beg your sister to release your dick, but she always says that its too early. Suddenly, the bell rings. Its your girlfriend. Fuck! You beg your sister to take it off. She just responds: “Not yet” and winks at you. The bell rings again, you open the door, your sister goes to her room.

Your girlfriend looks fantastic. She wears the most beautiful dress and obviously put a lot of effort into hair and make up. She missed you a lot. She jumps into your arms and kisses you, full of excitement! You just try to move your hips in ways that she not accidentally feels your chastity cage through your pants. God damnit, why didnt your sister remove it already…

You try to make the best out of it. You cook, you flirt, you talk a lot about all the things that happened in the mean time. You missed each other so much.

Finally, the topic comes up. Your GF says with an innocent smile: “So…are you ready for…tonight?”

Yes! So ready! If she knew how much preparation you went through, just to give her the night of her life now.

But wait! Shit! You’re still wearing this damn cage! You tell her you have to go to the bathroom. You give her a kiss and run into your sisters room.

She sits on the bed, in the sexiest little outfit you’ve seen her so far. You lose all the anger you just had and you just look at her, mesmerized for a second, before saying: ”Hey..sis…can you please unlock me now?”

She looks at you, up and down your body, smiles, pretends to think and then says: “Alright bro, I think youre ready.”

She makes slow, deliberate steps towards you, swinging her hips. She comes very close, so close that her breasts touch your chest for a second, and her lips almost touch yours.

She looks into your eyes and slowly unzips your pants and lets them slide down to your ankles. Then she goes down and pulls down your underwear, revealing you dick, contained in the chastity cage right before her lips. After brushing her fingers around your thighs, balls and the area above your shaft, she stands up again, moves her hand sensually over her own chest, and into her cleavage. From there, she pulls out a little key. Without breaking eye contact, she grabs your package gently with her left hand, and puts the key in with her right.

She takes the chastity belt off and you finally feel the freedom. Your dick looks like it shrank a bit after 10 days in chastity, but it is instantly rock hard. Your sister grabs and squeezes your balls one more time, puts her cheek onto my cheek, touches my earlobe with her thick lips and whispers: “Dont forget our training. Think about all that we have done, and whatever you do, dont cum too early.”

She gives me a final little slap on my ass, I pull up my pants and rush excited into the living room. Without saying anything, I grab my girlfriend, pull her against me and kiss her passionately. She smiles and bites her lip, I lead her into the bedroom. I cant wait any longer. I throw her onto the bed and we make out.

She feels my hard dick and says: “I cant wait to finally have sex with you! Take me! Make love to me all night!”

That is my sign. I take off my clothes, then hers. Her body is beautiful…maybe not as beautiful as my sisters but….wait, lets not think about my sister now! I’m gonna make love to my girlfriend. She lies in front of me, just in panties and bra! Smoking hot. I unzip her bra and touch her boobs. They feel and look fantastic. For a second I wonder how my sisters boobs look and feel like….but then I snap out of it again. I’m here, about to actually have sex! Have sex with the girl I love! I move my hands down her body, grabbing her panties. While I pull them down her beautiful thighs I feel a twitch in my dick. Wow I’m really horny, and really hard. And soon I will be inside her! Feel that warmth and wetness again! Another twitch goes through my dick. Oh my god, dont tell me…. No! I did all that training, I did another 10 days in chastity, I’m ready!

Thats when I see that the door is slightly open. My sister is standing in the door, looking at us, her left index finger on her mouth, signalizing me to not say anything, her right hand in her panties….touching herself! Is this really happening? But it wont stop me, I’m finally gonna do it. My sister prepared me all this time, I guess its fair that she watches my final performance. And somehow I like the thought. She is touching herself, watching me fuck. She actually gets turned on by that. Hot, in a weird way.

I snap back to my mission. I see my now completely naked girlfriend in front of me, and it drives me crazy. She breaths heavy, ready to be penetrated by me. I spread her legs, like I practiced with my sister and revised in my head so many times. That moment, my dick became harder then I imagined was possible. I moved closer to her entrance. I see the wetness dripping down her pussy and know that its about to happen. I move closer and closer to her pussy, and pictures of the training with my sister, of me cuming onto her belly, of her laughing at me and calling me premature ejaculator snap into my mind. I feel an intense sensation building up in my dick. Thats when I see a little clear fluid drop on its tip. Precum. Why is there already precum?

Stop it! Focus! You trained for this! You finally touch the entrance of her pussy with your tip, and you feel like you are getting so close…focus! Like you practiced! And DONT CUM! You need to feel it now, you need to feel an actual pussy. You want to be inside your girlfriend!
