All day long, Stefan could think of nothing but the surprise his sister wanted for him. During the biology lesson he didn’t even try to look at Mrs. Harloft’s cleavage, instead he played with thoughts of Natasha.
The only time that day he was jolted out of his reverie was when he saw Allie put her arm around one of the school’s football players. Envy and anger boiled up inside Stefan, but he would only lose to this box of a man. Frustrated, he returned to his math assignments.
The ordeal ended when, after too long, the afternoon bell rang. Stefan almost knocked people over in the hallway as he made his way to the exit. When he arrived, panting, Natasha was already waiting for him.
Giggling, she looked at his flushed face and mouth wide open for air. “Well, someone was in a hurry,” she scolded him, “so excited! Then come along!”
Stefan almost felt like a dog as he followed his sister to her car. She seemed to be up to something, too, because she was fiddling around in her bag the whole time. But when he got into the passenger seat of her Mercedes, she ignored him and started typing a message on her cell phone.
“Seriously?” grumbled Stefan.
Annoyed, Natasha looked at him. “You want something from me, not me from you. Be patient!”
Sulking, Stefan began to look at the people outside on the street. Couples were making out in front of the school, groups were talking, and nerds were running for the bus. Allie exited the building, her caramel-colored skin glistening in the sunlight. Close behind her, the guy from the morning.
“Are you still staring at Allie?” his sister suddenly asked.
Stefan remained silent.
“You know she’s already got one going on, right?”
Again, Stefan didn’t dare comment. Shrugging her shoulders, Natasha started the engine.
After about fifteen minutes of driving, they stopped at the edge of a forest.
“Are you ready for your surprise?” asked Natasha.
“Sure,” Stefan confirmed uncertainly. There was something in his sister’s voice that scared him. But when she opened his belt, those worries were quickly forgotten.
Natasha still opened the trouser buttons for him, then she paused.
“This is boring,” she mused aloud, “I should blindfold you. Lean your head forward, little brother!”
Befuddled, Stefan obeyed. His sister pulled a scarf from her glove compartment over his eyes, which she then tied behind his button. “Relax, little brother!” she recommended.
Then Stefan felt her slowly remove first his pants and then his underpants. He still tried to help her, but a gentle hand right on his thigh pressed him back into his seat. “Let me,” Natasha commanded.
So Stefan let himself drift, in the sea of sensations. He heard his sister open a tube and rub her hands together. Then she grabbed his penis, already hard from anticipation. She began massaging it to spread the cream. She knew exactly what she was doing, it was getting hotter and hotter in Stefan’s loins-.
Suddenly Stefan groaned as his sister squeezed his balls. Just as he was about to rip the scarf off his head, he felt metal on his cock and heard a *click*. A few moments later he was fully rid of the improvised blindfold and saw what had happened: his cock, glistening with lube, was stuck in a long, metal cage.
“What the fuck?” he cried angrily.
But his sister next to him just laughed and wiggled the key.
“Be nice, I have the key!” she clarified.
“Damn it, give it back! That’s illegal!”
“What are you going to do, call the police? ‘Hello, my sister is having sex with me and she’s locking my little dick in a cage so I can’t jerk off so sad? Have fun with that!”
Desperately, Stefan pondered. The police were indeed no solution, neither were the parents. Maybe he could free his best member with a pair of pliers? Conversely, it was very risky, so close…
Natasha, who had probably sensed his thoughts, calmed him down. “You’re not stuck in there forever. But now the real part of your surprise begins, so pull your pants back up while I drive!”
For a solid ten minutes, the two drove in silence before stopping in front of a house. A house Stefan knew from photos.
“That’s where Allie lives,” he noted.
“Right. You coming?” His sister had already gotten out of the car and was heading for the doorbell.
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 thought. What was he doing here? But the tone of Allie, who ordered *Now!*, allowed no argument.
