Damian and Crystal sat on the three seated rough sewn brown couch, side by side. Their mother, Susanne, gathered the last bit of materials for work. Susanne walked from one end of the kitchen to the living room and back to the kitchen. For a woman in her mid forties she had the body of a woman half her age and the looks of a woman a decade younger.
She had long brown hair that flowed behind her as she walked. Her large C cup breasts jiggled as she hurried from fridge to freezer bag. Susanne gathered the last bit of food that she needed for her twelve hour shift at the hospital and zipped up her bag. She wore a dark purple nurse top with matching purple bottoms.
"Okay you too. Have a good day and be safe. Get to work on time. I love you both." She said as she hurried out the door.
"Love you too mom." Crystal said hurriedly just before the front door closed. Crystal, like her mother, had brown hair only she kept it shoulder length. Unlike her mother though she did not have large breasts. What Crystal did inherit was her mother's hourglass figure and her perfectly sculpted ass. Damian on the other hand had inherited their late father's features.
A lean and muscular figure with broad shoulders and nearly black hair and pecan tan skin. Unlike his father though who had brown eyes, Damian had blue eyes, sapphire blue eyes. Growing up their father was always away on trips for business and their mother had to work extra shifts to keep things afloat. Which left Damian who was now 23 and Crystal who was now 21; alone most of the time.
Alone to adventure the city and forests around them. Alone to explore their large house and...to explore each other.
"That could've been bad." Crystal exhaled as she heard their mother's car leave the driveway.
"It's fine." Damian said assuredly as he slid his middle and ring finger in and out of his sister's moist pussy.
"What if she...would've caught us?" She asked between labored breaths of pleasure.
"She wouldn't have'' Damian growled as he leaned in and started kissing her neck. Crystal let out a soft whine of pleasure as she felt his tender lips caress her soft skin. He kissed under her jaw line and down her neck to her shoulder and across her chest.
Crystal felt hot all over. A warmth that was like her blood had started boiling and she needed to release the pressure. Damian could sense his teasing touches were pushing his sister to the brink of need. He liked it when she was on the edge of losing herself in pleasure. Damian slowly slipped off her tank top and pulled it up and over her shoulders and head.
He continued kissing her chest downward and paid close attention to Crystal's B cup breasts. While their mother had large breasts that verged on being a D cup, Crystal had small breasts with very large nipples. Very large 'sensitive' nipples. He coiled and swirled his long tongue around her pink nipple and quickly it grew.
"Dammit Damian thats...ah...no fair." She whined as her nipple sent a shiver of pleasure across her body. Crystal hatred how large her nipples got when she was aroused but she didn't hate how much her brother loved them. He softly nibbled on both her nipples and pulled on them gently. Even as he toyed with his sister's breasts he never stopped finger fucking her now sopping wet pussy.
Using his thumb he started rubbing her exposed clitoris. Crystal tossed her head back and let loose a moan of pleasure.
"Dammit that feels good." She moaned.
Damian snarled as he took her left nipple into his mouth, suctioned his lips around it and then bit down and started sucking and licking.
"Fuck!" She shouted. Crystal couldn't take the combination of pain and pleasure in two of her three most sensitive spots.
Damian felt her hips start to shift and he could feel her vagina tighten around his fingers. He curled his fingers into a hook and started fucking her pussy vigorously.
"Son of bitch! Fuck me! Yes!" Crystal shouted and arched her back. "Oh fuck I'm gonna cum! Holy shit I'm cumming! I'm cumming!" She screamed and a rush of cum poured into his hand just before she flopped to the couch in exhaustion. Damian pulled away and smiled. She looked down at her left nipple which had a red ring of teeth marks around it.
Quickly each tooth indentation turned a dark red color and would surely turn purple. Crystal loved the way her brother marked her as his own. She turned over onto her knees and pulled down her shorts and stuck out her pussy which was dripping.
"Sorry sis." Damian smirked. "I've got the early morning shift today."
"So you just give me one little orgasm and then leave?" She asked angrily.
"Yup." He winked and headed up the stairs to his room.
"Bastard!" She shouted.
"You love me." He laughed.
Crystal huffed angrily because she did love him. It had only been a year since they started becoming physical with each other. She had dated a hand full of other guys during high school and college but none of them could give her what she needed. Only her brother could do that.
Damian got dressed in his usual black slacks with a black button up and a silvery-gray vest. He slid on his black boots and laced them up and went back down stairs. Crystal had put her shorts back on and sat on the couch with her arms folded.
