Sheldon was in shock. He knew he couldn't leave, it would kill Mary, but he didn't trust Missy and knew she was evil deep down to the core, but just thinking about fucking her was worth the chance of bringing his mother into a threesome too. He knew how strict his mother was and wouldn't fall for Missy's shenanigans. He went to bed and had evil dreams about fucking both his sister and mother. He woke up in a cold sweat and nearly made a run for the train station, but knew his mother would never forgive him. He had to stay clear of Missy if possible tomorrow and the next couple of days.
He got up in the morning and came out in his robe and stopped dead in his tracks. Missy was wearing a sheer nightie under a drab old robe. She flashed him, several times, each time Mary left the dining room to get more breakfast food. Even without the catch phrase, he was getting a hard-on and gave up trying to escape his sister's clutches.
Mary was clearing the dishes when Missy tuned to Sheldon and giggled, "Sheldon Lee Cooper is by far the most incredible lover and his huge cock is magnificent." She giggled again as she finished the catch phrase and suddenly she was overcome with the urge to jump his bones.
Mary came back into the dining room and sat across from Sheldon and her demeanor changed within seconds of sitting down. Her lips parted and her breathing increased as she began squirming about in her chair. "Missy would you please take Sheldon into your bedroom, I'll be there in a few minutes, I have to take care of a few things before joining you."
Sheldon looked at his mother in a different light as he stood and allowed Missy to lead him into her bedroom. Once there she pushed Sheldon down onto her bed and took a couple steps back. She undid the belt on her drab robe and let it slip from her gorgeous body. She approached the bed and stood between his legs that were hanging off the bed. "Are you gonna fuck both Mom and me Sheldon? I want to suck on that magnificent cock Beverly says you have, it that okay?"
He just lay there taking in Missy's beautiful body. A smile crossed his lips and he reached down and unbuckled his pants and lowered the zipper. He raised his ass off her comforter and tugged off his pants and jockey shorts. He tossed them aside along with his socks and grabbed hold of his stiff cock. He slapped his thighs from side to side and it grew longer and stiffer. He pointed towards Missy, is this what you wanted to see and play with?"
She stood there, her mouth opened, but nothing came out. She nodded and approached the bed. She planted one knee on the bed and she let out a scream. She suddenly found herself flat on her back with her head hanging off the side of the bed. Sheldon was standing beside the bed, his fist was wrapped around his cock and he was slapping her cheeks from one side to the other. He cradled her head in the palm of his other hand and tilted her head towards his cock. He fed his huge cock into her wide-opened mouth. He let out a gasp as she craned her neck and gobbled up more of his shaft. He knew immediately she knew her way around a cock, no matter the size.
Missy glared up at him and her tongue flattened out and she rolled it around his shaft and reaching out, she grabbed hold of his bare ass and pulled him closer to the bed. She swallowed more of his cock and she rubbed her nose against his nut sack that was swaying back and forth before her. She worked her throat muscles, milking his cock without even moving her face.
Sheldon knew she was an expert cocksucker and she didn't disappoint. That is why he forced her onto her back and fed her his cock with such force. He knew she was a slut and was going to treat her that way. This was something else he was going to have to thank Beverly for. He was close to cumming. Just hearing the sloshing of his cock sliding in and out of her mouth and throat was making his balls churn and was nearing the point of pasting her face with his cum.
He staggered back and rested against Missy's dresser when his mother flung open the door and entered. He stared at her and saw her eyes drop to his stiff cock as it bobbed up and down, covered in Missy's thick throat mucus.
Mary stood there; she had changed her clothes and was standing there in a wicked Catholic School Girl Outfit. She had it down to a tee. Hair in pigtails, starched white blouse tied below her breasts leaving her belly bare. Her hips and ass were covered in a red and green plaid pleated skirt that ended at mid-thigh. Below that she was wearing saddle shoes and white bobby-socks. Her lips were painted a bright red and her dark eyes were lidded with equally dark eye shadow. He felt his cock jerk as she approached him and standing a few inches from him until his cock poked her in the belly. It left a streak of pre-cum and Missy's saliva on her heaving belly.
Mary turned to Missy, "Once a slut, always a slut huh?"
Missy giggled and slipped off the bed and came up behind her mother and wrapped her arms around her and placing her hand on Mary's belly, she slid them beneath her blouse and cupped Mary's bare tits, "Never knew your mother was so fucking kinky did you, Sheldon. You should see the threesomes the two of us get into. Some are from the church and some are friends of mine. She really gets kinky with the associate pastor, his cock isn't anywhere as large as yours, but he can really fuck for hours." She lowered her head and nibbled at the bare flesh of Mary's neck and she giggled when she felt her shiver, "Right mom?" She placed her hands on her mother's shoulders and pushed down and Mary slowly slipped to her knees and knelt before Sheldon's straining cock, "Suck it mom, look how fucking huge it is. I had a tough time gobbling it all down, but forced myself and you'd be proud, I got it all in."
Mary stared at it, her hot breath coating the shaft as she came closer and closer to it. She parted her lips and grabbing hold of the shaft, she fingers barely met in her long slim hand. She swiped the leaking head all along her slick lips and her tongue darted out and added to the wetness there. She inhaled, taking in the scent of him and the extreme amount of pheromones he was expelling. Her eyes grew tinier as lust clouded her demeanor and she opened her mouth wider and suddenly Missy pushed at the back of her head, making Mary choke on the huge cock that slammed against the back of her throat. She pulled back and gasp for air as she tried to recover, "My Lord Missy, why do you always do that to me. I'll suck on it, but let me do it at my own pace."
Sheldon was still leaning back against the dresser as he watched the sexy Catholic school girl kneel before him, sucking and licking at his stiff cock. He looked at Missy who was pulling the nightie from her body and he smiled when she tossed it to him. He inhaled her sexy scent and tossed it aside and motioned for her to come over beside him.
Missy, now naked snuggled up beside Sheldon and stripped off his t-shirt and began raining kisses all over his neck and chest. She cupped his head and guided it to her huge swaying tits. She let out a groan when he drew one of the large crowns between his lips. She arched her back, forcing more tit flesh into his mouth.
Sheldon was close to cumming. Having his sister's tits forced into his mouth and his mother kneeling before him with his cock halfway down her throat. He continued to suck on Missy's tits as his hands clutched at his mother's pigtails and pulled her even further onto his cock.
Missy wanted some of the action and even though she loved what Sheldon was doing, she pulled away and she giggled seeing her tits coated in her brother's saliva. She knelt down beside her mother and slipping lower, she began lapping away at the nut sack containing all of the hot sperm she yearned to taste.
Mary released his cock with a pop and gripping it, she guided it to Missy's mouth and she settled back on her haunches and watched her daughter swallow her son's huge cock, "Mu God Missy, we're going to hell for doing this, but I can't resist. How about climbing up on the bed and let Shelly fuck that luscious cunt of yours.
Sheldon was shocked by the nasty words coming from his mother's mouth, but right now all he could think about was burying his cock in his sister's pussy and after that, do the same to his mother. He turned to the bed and saw his beautiful sister lying flat on her back. He gazed at her and saw how her large breasts were spread out on her chest. He loved how her long dark hair framed her face and made her look nearly angelic, but he knew what a slut she was and was going to give her the hard fucking she so desperately deserved. He turned to his mother, "Come over here Mother, grab my cock and I want you to feed it into your slutty daughter's slimy cunt."
Mary drew in a deep breath and stepped forward and grabbed hold of his cock and tugged at it till he was lined up with the glistening lips of Missy's cunt. She watched as he arched his hips and began to sink into her receptive pussy.
