CHAPTER 8
“Ohmygod ohmygod ohmygod!” She panted and Matt had her hold her up by her hips as his stepsister’s knees threatened to give out. “Oh, fuck…”
“Ugh! Mmm god,” Matt let slip a grunt as he felt himself nearing cumming himself. He went to pull out of her, and Stephanie’s body shot to life. She looked behind her, flicking her hair over her opposite shoulder, as she always did when her brother was about to cum, but this time her hand reached back, cupping around the back of his bare thigh.
“No!” she protested. “Don’t- cum inside me, baby,” Stephanie demanded. Matt was shocked and continued to thrust inside her. He was so close to the edge.
“Don’t stop mhm! Don’t stop fucking me baby,” Stephanie winced. “Cum inside me, cum inside my tight- fuck ah ahh! Please, cum in me!”
Matt’s cock crammed deeper inside her until her knees started to shake and her eyes nearly squinted shut from the feeling. Matt gritted his teeth as felt the threshold pass and he came hard, shooting his load into his sister’s pussy. Filling her up with his cum and holding his shaft deep inside her.
His arms wrapped around her chest, he spooned with her as his chin nuzzled against the crook of her neck. They stayed there for several minutes until his cock went completely limp. With his jizz and her juices coating his shaft, he fell out of her.
Matt and Stephanie lied on the bed for a few minutes naked and giggling at each other. The party was loud outside the room, with people shouting at another and falling into walls. Despite being as loud as Stephanie moaned, Matt doubted if anyone heard them. It didn’t matter. In that moment, all that mattered was Matt’s eyes meeting Stephanie’s eyes and he refused to let the moment slip away.
The following week, Matt arrived at his stepmother’s house for his weekly meeting with Stephanie a bit later than usual. It was about 7:45pm when he arrived instead of his usual 6:30pm when Stephanie’s Mom left the house for her date night. It was his father’s fault for his tardiness.
His new stepfamily had a sit down to discuss their upcoming vacation. His father was taking them camping in a cabin in Wyoming in a couple weeks. He pitched it as a family bonding experience, but really it was to make sure everyone knew he was the one in charge of this family, and most likely he was using it as an excuse to corner Matt about his impending college decision.
As annoyed as he was with his father, Matt felt relaxed as soon as he put his car in park at his stepmother’s house. Even though it was late, it wouldn’t affect his and Stephanie’s plans. Over the past month Stephanie’s mother, Amy, hadn’t come home until Sunday morning each night, which gave him and his stepsister plenty of time.
Matt and Stephanie hadn’t seen each other since the party. They fell asleep spooning together and Matt woke up and left early before anyone else was awake. Stephanie assured him later that day that none of her roommates or anyone else suspected anything besides that her stepbrother was a lightweight. Matt didn’t appreciate the stigma, but there were worse ones to have, he supposed.
The week of texting with his stepsister had been filled with hidden smiles and an exchange of dirty pictures. Their strained relationship had left the confines of the little game they played, pretending what they did didn’t happen and was now out in the open.
In fact, as soon as Matt got inside Amy’s house and found Stephanie in the living room on her phone, she tossed her phone to the side as Matt slid onto the couch beside her.
“Hey there, cutie,” Stephanie smiled. Her hands cupped the sides of his face as she kissed him. Matt’s hand reached across her chest and felt her breast moving freely under her shirt.
“Sounds like we fooled everyone at the party, then?” Matt asked as Stephanie crawled onto Matt’s lap, straddling him.
Stephanie laughed as her fingers went right to work unbuckling his belt. “You didn’t help us either. It was like you wanted us to get caught.”
“Me?” Matt smiled. “You were the one making all the noise. I just didn’t want you getting away.” He leaned back and let his stepsister undo his pants for him.
Stephanie giggled with a long smile on her lips, “I couldn’t help but make noise when someone was smacking my fucking ass.”
Matt shrugged, “well, you seemed to like it.”
Stephanie released a sighing moan as she leaned in to kiss her stepbrother. Her fingers had rushed to unzip his pants and pulled his cock out from under his boxers. As she felt it grow in her palm, she let out a high-pitched moan as she stroked it to life. Matt’s hands wrapped around her ass cheeks to find she wasn’t wearing any shorts or panties. She lifted enough to guide the head of his bare cock inside her. “Mmmm! That’s it…” she cooed.
Stephanie raised her ass and lowered it, riding Matt. She hastily pulled her shirt off, revealing her perky breasts. Matt leaned forward, wrapping his lips around her nipple. “Mmmmm! That’s right, baby. Fuck me. Fuck your stepsister!” Stephanie moaned as she sat down on his throbbing cock.
“Stephanie!”
The voice was so sudden and loud that both Matt and Stephanie nearly fell off the couch. Stephanie scrambled to cover herself, but Matt was too much in shock to even try to cover his raging hard on. All Matt could do was look at Amy’s wide eyes and shocked expression as she stood in the living’s entry room and stared frozen. Amy’s expression slowly turned to rage as she processed the image of her daughter having sex with her stepson.

There are times in people’s lives when pure dread sinks their teeth into one’s back like a predator. When they knew their life as they knew was coming to an end. As Matt scrambled to pull his jeans up and push his erection back down into his boxers, he had one of these moments. Luckily for him, at this very moment, his stepmother was more intent on chasing down Stephanie who ran into the hallway with her clothes.
It was pure pandemonium coming from Stephanie’s bedroom. Someone was crying while the other was cursing and throwing things. Matt tried to zip his pants up and nearly synched his shaft in the metal.
“Ah ah, fuck! Fuck it.” Matt whispered to himself and tried to make a break for the door while it was still clear. His erection still throbbing, pointed out his unzipped pants but he couldn’t deal with that right now.
He cleared the hallway and was halfway through the kitchen when the tumbling of clothes, bags, and people came tumbling down the hallway. The tornado that was their argument pushed past him and he saw Stephanie shove outside with her hands full with two bags and some of her clothes. Amy chased Stephanie outside but stopped at the edge of the steps shouting.
“We are going to talk about this!” Amy screamed. “You aren’t welcome back here until we talk about this, young lady!” Stephanie threw her car in reverse and drove away, allowing silence to overtake the house again.
The sound of Stephanie’s car engine sputtering to life then driving away left a strange silence which meant he was alone with his stepmother and she could turn her anger towards him at any moment. He wondered if he could maneuver around her in the doorway somehow and make a run for it.
