Tim's thrusts between Sophia's breasts became rough and erratic. His small hands gripped the sides of her heavy tits tightly as he fucked them with quick, desperate strokes.
The swollen head of his cock kept poking out from between her soft flesh, smearing pre-cum across her chin and lips with every forward thrust. Sophia kept her breasts pressed together obediently, her fingers sinking into the warm, pillowy skin as she tried to keep them wrapped around his cock.
I was sitting on the floor near the bed, my own cock in my hand. I couldn't stop myself. Watching my gentle older sister get her tits used like this, seeing Tim's cock disappear between those massive, soft mounds again and again. My hand moved faster as I stroked myself, my breathing heavy and uneven.
Tim suddenly let out a low, strained groan. His hips jerked forward hard and he pushed his cock as deep between her breasts as he could. Thick ropes of cum shot out powerfully, splattering across Sophia's face.
The first thick spurt landed directly on her cheek, followed by another that streaked across her nose and lips. More cum kept coming in heavy pulses, painting her face in messy white streaks. Some of it landed on her chin and slowly dripped down onto her neck, while a few stray ropes landed across the upper slopes of her massive breasts.
Sophia's eyes were closed, her face flinching slightly with each hot spurt that hit her skin. When Tim finally finished, her face was covered in his thick, sticky cum. It was smeared across her cheeks, her nose, and her lips. Some of it had even gotten into her hair. A few droplets clung to her eyelashes. She looked completely wrecked, her face painted white with another boy's cum while she still held her own breasts together.
Tim's body shook as he came down from his orgasm. He let out a long, satisfied breath and slowly pulled his cock out from between her tits. He looked down at Sophia's cum-covered face with a wide, satisfied grin, clearly proud of the mess he had made.
Sophia slowly opened her eyes. She sat up a little, her face still dazed. Some of Tim's cum dripped from her chin and landed on her bare breasts. She reached up with one trembling hand and touched her cheek, scooping up some of the thick white fluid onto her finger. She brought it close to her face and looked at it, her nose scrunching up slightly at the strong, musky smell. Her expression was a mix of embarrassment and confusion as she stared at the cum on her finger and felt it cooling on her skin.
Before anyone could say anything, the sound of the front door opening and closing echoed through the house.
Sophia's eyes widened in panic.
"Oh gosh... Simon is back," she whispered sharply, her voice filled with sudden fear. She quickly climbed off the bed, her naked body moving in a rush. Cum was still dripping from her face and chest as she hurried to grab some tissues from the bedside table. She wiped her face frantically, trying to clean off as much of Tim's cum as she could. Some of it had already started to dry on her skin.
I quickly stood up and pulled my pants back on, my heart racing. Tim was still lying on the bed lazily, his softening cock out in the open. He looked half-asleep and completely unbothered.
Sophia pulled her sundress back on in a hurry, not even bothering with her panties. She smoothed down the fabric quickly and turned to me.
"Robbie, put his pants back on. I'm going down first," she said in a rushed, panicked whisper.
She hurried toward the door, but suddenly stopped. Her eyes widened again as she turned back and ran toward the wardrobe. She grabbed a bottle of perfume and sprayed it generously over her neck, chest, and arms, trying to cover up the strong smell of Tim's cum that was still clinging to her.
Then she rushed out of the room.
I walked over to Tim and nudged him with my foot.
"Hey, brat. Wake up," I said sharply.
Tim opened his eyes slowly, rubbing the back of his head with a confused expression. When he heard me mention that Simon was home, his eyes shot open wide. He quickly sat up and pulled his pants back on in a hurry.
We both left the bedroom and walked down the stairs.
Simon was sitting at the dining table, looking tired but relaxed. He had a few shopping bags beside him. When he saw Tim, his face lit up with recognition.
"Oh, Tim? You're here too?" Simon said with a small smile. "Haven't seen you in a while, kid. How've you been?"
Tim put on his best innocent face immediately.
"I'm good, Uncle Simon. I came over to play with Big Sis Sophia and Brother Rob. We were having a lot of fun upstairs," he said cheerfully.
Simon chuckled. "Is that so? That's good. Robbie, you're getting along well with him?"
I forced a smile. "Yeah… he's a bit energetic, but we're managing."
Tim glanced at me with a hidden smirk before turning back to Simon.
"Rob is really fun to play with," Tim said innocently. "He gets really into the games. Sometimes he even lets me win on purpose."
I clenched my jaw but stayed quiet.
Simon laughed lightly. "That's nice of you, Rob. By the way, I brought steak today. Why don't you stay and eat dinner with us, Tim?"
Tim shook his head quickly, still keeping up his polite act.
"Thank you, Uncle Simon, but I should go. My mom will get worried if I stay too late. She told me not to stay late."
Simon nodded understandingly. "Alright then. Next time, okay? Tell your mom I said hi."
Tim nodded and gave a small bow. "I will. Bye Uncle Simon. Bye Big Sis. Bye Brother Rob."
He turned and walked toward the door, but not before shooting me one last smug look when Simon wasn't watching.
After Tim left, Simon gestured toward the dining table.
"Come sit, Rob. Food's still warm. You must be hungry after playing all evening."
I walked over and sat down across from him. My mind was still spinning from everything that had just happened upstairs. Sophia was moving around in the kitchen, trying to act normal, but I could see how tense her shoulders were.
"he is such a good kid, right? He seems pretty attached to Sophia."
I shrugged, trying to keep my voice steady. "Yeah, Sophia's always been nice to the neighborhood kids."
Simon nodded. "Yeah, she's always been like that. Too soft-hearted sometimes." He glanced toward the kitchen where Sophia was and smiled fondly. "But that's one of the things I love about her."
Sophia came out of the kitchen carrying plates, her face still slightly flushed. She avoided looking directly at me as she set the table.
Simon looked at her and frowned slightly. "You okay? Your face looks a bit red. And… is that perfume? You don't usually wear this much."
Sophia froze for a split second before forcing a smile.
"Ah… yeah. I spilled something on myself earlier while playing with the kids. I sprayed some perfume to cover the smell," she said quickly.
Simon nodded, accepting the explanation without suspicion. "You should be more careful. Anyway, let's eat before it gets cold."
