[FFM] A Family Secret (Incest)

Cassie sighed upon seeing her brother’s car already parked in HER spot in the driveway. “Chris, you’re such an asshole,” she grumbled, before swinging her own car alongside the curb in front of their home. Ever since her older brother had returned home from college, he had taken over the house with his inconsiderate habits. She had complained to her mom about it, about how it wasn’t fair she was forced to clean up after him and deal with his rude behavior. She even texted him this morning to remind him to park on the street! But Mom always took her brother’s side…if only Dad were still around to whip Chris into shape. Cassie grabbed her bag and browsed through Instagram on her phone while strolling up to the front door.

“Oh my god!” she exclaimed when a picture of her brother, shirtless, appeared on her feed. She stared at his strong shoulders and abs in begrudging awe before she noticed the caption, “About to clap some cheeks!” She glanced at the timestamp and saw he had posted it a half hour ago. “So gross,” she thought, “he better not be fucking that slut in our house.” Her room shared a wall with his, which meant every time his girlfriend Jennifer paid him a visit, she had to either blare music over her headphones or risk hearing Jennifer’s stupid giggling and, sometimes, hushed moaning. One time, when Chris and Jennifer must have not realized Cassie was home, Jennifer’s unrestrained scream of, “Fuck me with that huge cock!” pierced through Cassie’s headphones. Cassie had relayed the story to her friends in disgust. She left out how soaking wet she was afterwards.

She unlocked the door and walked inside to see a lacy bra draped over the banister. “Seriously?!” she muttered, gingerly lifting it up. Is it Jennifer’s? As she climbed the stairs, sounds of pleasure echoed down the hallway. Yup, Jennifer must be over. Cassie considered shouting at them to keep it down, but her curiosity suddenly got the best of her. She quietly made her way up to the second floor and turned the corner to see…Chris’s room door wide open? No way he would be that brazen! She crept to right outside his door, a strange excitement rising inside her chest. “What am I doing?” she hesitated, before quickly glancing into his room. Wait, what? She looked inside again and confirmed that his bedroom was indeed empty. Her confusion was answered when she heard a moan and nearly jumped.

“Oh Chris!” The sound emanated from further down the hallway. Cassie frowned. “Is Chris fucking in Mom’s room?” she wondered. Something deep inside told her she should go to her room and leave it be. But Cassie couldn’t help herself. As she approached the room at the end of the hall, she saw a pair of oddly familiar panties lying on the floor, right in front of the slightly ajar door. Where had she seen these panties before? It almost felt like an invitation to Cassie, who tiptoed closer, heartbeat pounding in her ears. She peeked inside the room, and realized where she had seen the panties before – the laundry basket in Mom’s room – her heart sank.

Her mom was riding her brother on the bed, eyes closed and mouth open in forbidden ecstasy, filled balls deep with a cock she created. Cassie nearly screamed, but stifled it and covered her mouth, horrified. Chris was fucking their mother. The scene before Cassie unfolded in slow-motion. Mom’s breasts bounced as she slammed herself onto her son’s thick rod. Her hands gripped the bedsheets and her face was fixed in an expression of pleasure mixed with consternation as she exclaimed, “This is so wrong!”

Cassie was in disbelief, and although tears welled up in her eyes, she was unable to look away. “But you feel so good Mom” Chris responded and their mother moaned in reply. “What the fuck” Cassie whispered shakily under her breath. A wave of emotions overwhelmed her: bewilderment, disgust, rage, and, although she wouldn’t admit it, jealousy.

Cassie felt a heat arise between her thighs as her breath started to labor. She bit her lip as her hand slowly wandered down the waistband of her leggings to meet her pulsing clit. Slow circles over her engorged nub quickly became furious rubbing. She nervously pulled out her phone with her other hand to record the incestuous encounter, savoring the thought of watching them on repeat in the privacy of her own bedroom.

Overtaken by lust, Cassie fell to her knees and stuffed a couple fingers inside her slippery entrance. Mom continued to vigorously fuck herself with her son’s dick harder and faster. Chris spanked his Mom and she yelped, causing Cassie to nearly cum all over her hand. Suddenly, Chris grunted, “Mom I’m gonna cum” and she immediately dismounted, aiming his cock at her awaiting mouth. Cassie watched with amazement as thick rope after rope of white seed covered their mom’s face. “Mmmm,” their mother sighed and licked her lips. Cassie orgasmed with her brother.

In the midst of her climax, Cassie inadvertently shared the video to the last person she texted. Her brother’s phone buzzed on the nightstand and he reached over to pick it up. Cassie looked down at her screen to realize her mistake, before hearing her secret recording blare from Chris’s speakers. “What…oh shit.” He immediately jumped off the bed and marched towards the door. Cassie panicked and attempted to run to her room, but her legs, weak with pleasure, collapsed beneath her. The door slammed open and Cassie, once again on her knees, was met with her older brother’s still swollen member directly in front of her eyes. She shyly looked up to see Chris glaring down at her and raised a glistening hand to greet him, “Hi?”
