"Shingo- stop."
Usagi pushes her little brother; not so little now, off herself lightly before placing another kiss on his lips. They were pressed against Usagi's car, so close it was impossible for Shingo not to get hard.
"No, come on nee-chan…" he begged.
"Our movie is about to start."
He almost forgot why they drove all the way here in the first place. Usagi was always so careful not to get caught, by their parents or her boyfriend. They had to drive to the nearby towns just to go on a date.
"Won't be the first time we have sex in a car," he said, hopeful.
"That was one time! Okay, two times. But I'm not doing that again."
"There's a motel just down the highway…" Shingo hated ignoring his erection, which happened a lot when he was with his older sister. All it took was for her to sit on his lap or wear a shirt that's just a little bit too tight, and he couldn't control himself anymore.
"I said no," she said softly. "But I'll make it up to you, I promise." Usagi kissed him before pulling away.
They walked into the cinema, bought tickets and popcorn, and then made out a few more times before the movie started.
The protagonist was a beautiful blonde in twin-tail, and she was naked in almost every other scene. Jaime couldn't help but imagine it was his older sister. He kept looking at Usagi in between scenes, wondering if she'll let him fuck her when they get home. If their parents are away that is.
Just as he was getting into the scene where the blonde was giving someone a blowjob, he felt a hand on his thigh, and in the next moment, his pants were already unzipped. He looked over at Usagi, confused, and she smiled before turning back to the big screen. Her hand remained where it was, and she started getting inside his boxers.
He was still hard, ever since they started making out in the car, and he knew he wouldn't last much. She touched his head with only one finger, driving him inside. After he let out a soft moan, she started stroking him, slow at first, and then faster. He was whimpering around his seat, struggling to keep quiet.
She kissed his lips once and whispered: "Come, Shingo. Come for your beloved sister. Come at once." And she didn't have to tell him twice. A few more strokes were all it took for him to spill his seed all over her hand, moaning and cursing quietly.
"I hope you're not too exhausted," she whispered into his ear as he started to fix his clothes, "you'll need a whole more energy when we get to the motel you mentioned."
