Sophia looked at Tim with wide, surprised eyes when he said it. The words hung in the air for a second. Her cheeks turned a soft shade of pink almost instantly. She let out a small, nervous laugh, clearly caught off guard by how bold the suggestion was.
"Tim… that's a little too much, don't you think?" she said, her voice light but uncertain. She glanced at me, waiting for me to say something. I could see it in her eyes — she was expecting me to step in, to say it was too far, to tell Tim he was going too fast with these rules. But I stayed quiet. My throat felt tight. I couldn't risk going against Tim right now.
Tim tilted his head, giving her that innocent-looking smile he was so good at. "It's just a game, Big Sis. It'll be more fun this way. Makes everyone try hard not to lose, right?"
"Robbie… you're okay with this too?" Sophia bit her lower lip, still looking at me. She asked softly. There was a hopeful note in her voice, like she was waiting for me to say no.
I swallowed hard and forced the words out. "Yeah… it's fine. It's just a game."
The moment I said it, something shifted in her expression. She looked a little disappointed, like she had hoped I would protect her from this. But she didn't argue. She never did when it came to these games. She was too gentle, too used to going along with things to keep everyone happy.
I knew he was planning to get bold now, but to make this kind of wish this early I was afraid what he would wish later on. My main concern was Sofia. In this racing game she would always lose, she wasn't any better than Tim or me at all. It was almost factual that she was going to lose every single race.
Tim knew it. That's why he chose to push the game in this direction. And somewhere deep down, Sofia probably knew it too. That's why she kept glancing at me, silently hoping I would say something to stop it.
But I myself was in a trench. It was better to stay quiet than to let that video get out and let everyone see that pathetic scene of me jerking off while watching my own sister get fucked. The shame of that would destroy everything.
Tim's grin grew wider. He knew he had won this round before the race even started.
We picked up our controllers again. The race began normally enough at first. Tim and I were both driving aggressively, bumping into each other whenever we could, trying to knock the other off the track. But Sophia's car was lagging far behind. She wasn't bad at the game, but she wasn't good either. Every time she tried to take a shortcut, she would mess it up. It was obvious she was going to finish last.
I felt a knot tightening in my stomach. If I could win this race, I would get the wish for the next one. I could use it to sabotage Tim's plan somehow. But Tim was playing dirtier than usual. He kept cutting me off, blocking my path on purpose. I tried my best, but in the final stretch he pulled ahead of me and crossed the finish line first.
"Yeeeaah! I won again!" Tim shouted, jumping up from the floor and pumping his fists in the air like he had just won the lottery.
I came in second. Sophia finished last, just like I knew she would.
Tim turned to her immediately, standing over her with a victorious look on his face. "Sophia Big Sis… you have to get naked now."
Sophia's face turned bright red. She glanced at me first, almost like she was hoping I would say something to stop this. When I stayed quiet, she looked back at Tim.
"Do I really have to do it?" she asked, her voice small and hesitant.
Tim crossed his arms, trying to look serious even though he was clearly enjoying every second of this. "You have to. You lost the game. Those are the rules we all agreed on."
Sophia hesitated for a few long seconds. She sat there on the floor, fidgeting with the hem of her sundress, her cheeks flushed deep pink. Finally, she took a shaky breath and stood up.
I couldn't look away.
She reached down slowly, her fingers curling around the bottom of her thin yellow sundress. For a moment she just held the fabric, like she was still hoping someone would tell her she didn't have to do this. Then she began to lift it.
The dress slid up her thick, soft thighs first, revealing smooth, pale skin that looked almost glowing under the bedroom light. The fabric continued rising, exposing the full, heavy curves of her hips and the soft lower part of her belly. As it moved higher, her massive breasts began to strain against the material until they finally spilled out when the dress passed over them.
They bounced heavily once they were free, the soft, full globes jiggling and settling against her chest. Her dark nipples were already stiff, and I could see small white droplets of milk still clinging to them.
Sophia pulled the dress over her head completely and let it fall to the floor beside her. She stood there in nothing but a pair of simple black panties. The contrast was striking, the dark fabric stark against her milky white skin, hugging the soft mound of her pussy.
The thin material was stretched tightly over her, and I could clearly see the outline of her puffy lips through it. A small, dark wet patch had already formed at the crotch, the fabric clinging to her folds.
She instinctively brought one arm up to cover her heavy breasts, while her other hand moved down to cover the front of her panties. But it didn't help much. Her massive tits were too big to hide completely, and they spilled over her arm, the soft flesh overflowing. Her thick thighs pressed together, making her hips look even wider and softer.
Tim was staring openly, his eyes wide and hungry.
"Do I… really have to take these off too?" she asked quietly, looking down at her black panties. Sophia shifted her weight from one foot to the other, clearly embarrassed.
Tim didn't even hesitate. "Yeah. You lost. The rule is fully naked."
