When Stefan was barely out of the car, his pants fitting more poorly than they should because of the metal thing between his legs, Allie opened the door. She looked stunning, even in the oversized jogging suit she was wearing.

“Come in Nattie!” she greeted Stefan’s sister. “You too Stefan!”

Perplexed, Stefan stumbled up the stairs into the house. As he took off his shoes, he could hear the two girls exchanging gossip.

“Come on up!”, Allie then beckoned him. Stefan trotted after her, her perfect bottom wiggling right at his face level.

Before he knew it, he was standing next to Allie in her room. His sister was leaning in the doorway.

“I know you like me,” Allie spoke up. “You want to do things with me. It turns out, I want to do things with you, too. But most men are so selfish!”

Stefan stood there, embarrassed.

“Take your clothes off!” ordered Allie.

For two seconds, Stefan wondered. What was he doing here? But the tone of Allie, who ordered *Now!*, allowed no argument.

When Stefan had pulled the T-shirt over his head, he saw that Allie had also worn something else under the jogging suit: The way she was standing in front of him now, she looked like a very hot superheroine, with a skin-tight latex corset and leather panties. Her breasts were so little covered that he could see beginnings of her black atria, and her skin was as smooth as caramel-colored satin. Briefly Stefan’s gaze wandered between Allie’s legs, but he quickly tore it back up.

“Don’t be shy!” laughed Allie, who had noticed. After all, I see you too!”

With those words, she pushed Stefan onto her bed, where she sat down next to him and fiddled with the metal cage between his legs. “Oh, so cute!” she squealed.

“Where was I?” she suddenly continued in a completely changed tone. “Oh yes, the selfishness of men. You know, earlier I had a visit from Michael, a football player.”

Allie pushed him onto her bed and began drawing circles on Stefan’s stomach. His sister was still standing in the corner watching.

“What am I telling you, you must have seen him. The guy from this morning you were so jealous of!”

When Allie noticed Stefan’s flinch, she sucked in an acted sharp breath. “Oh, you were even angry! And so helpless against him!”

Stefan blushed with shame. But Allie quickly calmed him down again as she began to draw her circles a little lower.

“I don’t like Michael very much. But you should have seen him in bed! I needed one of those, even if he only thought about himself, of course. Twenty minutes ago he left, and I’ve been lying here breathless. Now I could have gone to the bathroom to clean up, but then I thought about what Natasha told me about her brother.”

With those words, Allie lifted herself over him. Her hands on his shoulders prevented him from moving, and her dark brown pussy, also perfectly shaved, hung over Stefan’s face.

” Eat me, you little loser!” commanded Allie. Then she let herself fall on top of him, luckily leaving his nose free. ” Eat me like your life depends on it! Can you taste Michael inside me? Good!”

Stefan licked. He didn’t quite know what to do, mere minutes ago Allies pussy had been a wet dream for him. So, everything he got from Allie; he would take. Even if it was only the limp second course.

But she was not satisfied. “What are you doing, Stefan? Do you have lack of motivation?”, she exclaimed.

“Muuhh-No”, Stefan said with muffled voice.

“I think you do, yeah! I think we’ll need your big sis to help you!”

With those words, Allie seemed to turn to Natasha. “Get Mr. Frost, would you?”

Stefan heard his Sister opening a drawer and pull something out. Then, he heard the same drawer close again, and Allie gave him his freedom back. Then, turning around, she grabbed his head. “Do you see what your sister is holding?”

Stefan’s eyes shot open. It was a blue-white dildo, with a grip.

“That was my very first dildo”, Allie continued to explain. “I guess it will be your first, too!”

As Allie continued to talk about her experiences with Mr. Frost, Natasha pulled a condom from a box and slipped it over the dildo. It wasn’t THAT big, Stefan had seen bigger in Porn, but still, for a first time… As realization set in what was about to happen, panic began to rise in Stefan, and he felt a lump in his throat.

“C- Can’t we not do this?”, he stuttered.

Natasha laughed. “Look Allie, my little brothers scared! He’s about to lose his Anal virginity, and he’s scared!”

“Oh, don’t be”, Allie comforted Stefan. “It will be great! And you can leave whenever you want… But then, this’ll go away too.” Then, Allie grabbed her boobs and pressed them together with her hands. “Want to touch them, Stefan?”

Stefan reached out with his hand, but Allie stopped him. “Say that you want your sister to fuck you first!”

Stefan stuttered.

“Come on, say it! I know you want it!”, Natasha squealed excitedly.

“I… I want my… sister to-“ Stefan took a deep breath. “I want my sister to fuck me.”

“Good boy!”, both girls cheered in chorus. This time, as Allie pushed Stefan onto her bed, she let his arms and shoulders go free. And when she squatted over him again, all he had to do was reach out to touch those breasts he had been lusting about for years. They were soft, tender, and when Allie lowered her pussy onto Stefan’s face, he began to lick with new excitement. His dick was getting painfully hard in the chastity cage, but the pain was ignorable.

“Oh look at him!”, Natasha cheered. “Lil bro is excited! Let’s see how he handles Mr. Frost then!”

Then, she got to work. While Stefan was still eating out Allie and playing with her boobs, she gently caressed his rosette with cold, slippery hands. Then, she pushed a finger in, which made Stefan let out a sharp breath. He hadn’t even known about the nerves she was touching now.

“How does it feel?”, she whispered, “Me entering you? Does it feel wrong? Do you think it should be the other way around? Or is it just wrong because I’m your sister? Huh?”

The truth was it didn’t feel wrong. It felt incredibly humiliating, but Stephan was excited. It felt… Right?

Just as he wondered this, his sister drew back her finger. For a moment he stopped to eat out Allie because of the new sensation, but a quick slap from her reminded him to keep going. Then, his sister pushed the tip of the Dildo against Stefan’s rear.

A hundred feelings exploded in Stefan. He WANTED Mr. Frost inside him. He craved it. Out of excitement, he even began to caress Allie harder, and he felt pressure create inside him, despite being in a chastity cage.

“Your little bro can really lick!”, Allie commented. “I think we found his motivator!” Then, all Stefan heard from her were moans. Moans into which he joined himself as Natasha pushed hard against Mr. Frost, making the dildo enter Stefan’s ass.

“I’m in!”, she triumphed. Then, Stefan could feel her beginning to push even deeper. Once centimeter out, one and a half back in. One out, one and a half back in. The pressure in Stefan’s locked cock became unbearable. Allie moaned louder and louder, joined by Stefan. He couldn’t see his sisters face but could well imagine her devilish grin. And right as he pictured her, a lot of things happened.

The pressure inside of Stefan erupted. The cock, still locked in its cage, twitched, and shot ropes of white cum against the back of Allie. Natasha laughed surprised. Stephan began to tremble, and as he did, Allie came too, wetting his face with juices.

After a minute, Allie let go of Stefan and collapsed on the bed. “Oh my god”, she moaned, “Oh goodness!”

Stefan could do nothing but stare at the ceiling. Then, he heard his sister laugh as she pushed the dildo deeper into Stefan one last time, all the way to the balls. “You are ours!”, she whispered again and again, “ours!”
