It was Saturday night and Richard and Robyn had one more night to explore their sexuality before their parents returned home. Monday morning, her father would drive Robyn to a two day cheerleading competition.
Richard was standing at the bathroom sink, shaving, dressed only in his boxers when Robyn came up behind him and ran her hands and lips over his broad muscular back.
"Sis! Don't you ever get enough? There's a word for you, and that word is nymphomaniac."
She proceeded to run her hands down his body and into the back of his boxers to stroke up and down the crack of his muscular ass.
"Mmmmmm..I just love the feel of your sexy body."
"Do you realize dear sister that we have been fucking and sucking practically nonstop for over twelve hours? I don't think I have anything left."
Robyn gently parted the cheeks of his ass and slowly inserted a finger as she let her other hand move around him to his stiffening penis.
"Hmm, looks like part of you is still up for a little action. What do you say we do it in the living room?"
Richard removed the last of his shaving cream and spread his legs, enjoying his twin sister's roaming talented hands.
"You must have a death wish Sis. You know Mother doesn't allow anyone to go in there. That is a sacred room reserved only while entertaining company."
"That's what makes it so cool Bro. Doesn't the thought of making it being off limits make it even more enticing?"
Turning and taking his beautiful naked sister into his arms, his lips captured hers in a probing, demanding kiss. Breaking the kiss, he shoved his boxers over his feet and tossed them on the floor beside the toilet and grabbed his sister's hand and they headed downstairs naked.
They stood at the entrance to the spacious living room, taking in the marble fireplace, fine mahogany furniture, sculptures and original oil paintings.
Robyn took Richard's hand and dragged him to the couch. She pushed the heavy coffee table closer to the center of the room, then lay down on the couch and spread her arms out to invite Richard to join her.
He bent to begin to kiss her, but she held out a hand to stop him.
"Let's kiss when we fuck. Right now I want that delicious cock of yours in my mouth."
Robyn liked Richard to be on top because he had greater arm strength and could support himself easier, and also she could relax her throat easier to accommodate his full 9 inches.
She watched him slowly move above her to position his hairy ass and dangling ball sac inches from her face. As he lowered himself, she became lost in the strong male scent of his spread legs. She cupped his large balls in one had as she took his fat cock in the other and licked the pre cum from the tip. She took the large purple head of his dick into her mouth and gently moaned as she felt her twin slowly explore her moist slit with his tongue and fingers.
Richard lapped her sweet juices and sucked on the hardened clit as she devoured him and caused him to thrust deeply into her throat. Moans of pleasure filled the living room as they brought each other to a feverish pitch, making them oblivious to their surroundings, and making them unaware of the front door as it opened.
They could not however filter out the scream from Victoria Puritan as she saw her twins locked in their embrace on her sacred couch.
"My God in heaven!! Stop that instantly this minute."
She roared into the living room as Richard and Robyn disengaged their bodies and sat bare assed on the couch studying their folded hands and ready for the worst.
"I never thought I would see my own children, my own flesh and blood doing something so disgusting as licking each other. The is vile, and pure filth. We will talk about this tomorrow after your father and I have had a chance to determine your punishment. For now, both of you get to your rooms and don't come out for the rest of the evening."
Both teens rose and answered simultaneously, "Yes Mother," as they headed toward their rooms.
Wellington Puritan had remained silent during the whole ordeal, but for some reason he could not remove his eyes from the naked beauty of his daughter. Unlike his wife who thought body hair was unfeminine and unsightly and removed it all from her body, Robyn had a thick rich patch of unruly black hair between her legs. She also had noticeable feminine muscle on her legs, stomach and hips, which Wellington could not take his eyes off of as his daughter moved up the stairs to her room.
He felt his heart begin to pound faster, and silently berating himself for feeling arousal over looking at his own daughter. "By God, I am a Puritan, and we are above such loathsome feelings." As much as he tried, he couldn't tear his eyes away from her sleek animal body as it disappeared up the stairs.
All four Puritans tossed and turned during the night, but Wellington and Robyn were able to dress and pull out of the drive at 8:00 a.m. to begin the journey to the cheerleading contest. Wellington tried to focus all his attention on the road ahead, but he constantly snuck glances at her daughter's firm bronzed legs with the cheerleading skirt ending halfway up her thigh. He also studied her young full breasts remembering how they had bounced so provocatively and freely the previous evening. He refocused his efforts for the rest of the trip and thanked God when they finally pulled into the motel where they would be staying.
It was 8:30 when Richard heard someone rummaging around in the bathroom he and his sister shared, and he thought it was unusual since the staff had the weekend off. He crawled out of bed, dressed in his boxers and slowly moved to the bathroom where he got the shock of his life.
Dressed in a floor length black sheer nightgown was his mother, crouched, with her legs spread and one of her hands caressing her crotch. Her eyes were closed, and she held the pair of boxers which Richard had left on the floor up to her nose, and was inhaling deeply.
Richard watched in shock as her breathing became more ragged as her fingers moved faster and faster at her crotch. He had to admit that for a 40 year old, his mother had a beautiful body. It wasn't as full or hard as his twin, but years of tennis and aerobics had kept her body young and vital.
"Enjoying yourself?"
"Oh my God! Richard. Don't ever do that to me. You nearly scared the life out of me."
Richard crossed his arms as he leaned against the door frame and studied his mother as she tossed the boxers aside and straightened her hair with both hands.
"I was just straightening up a bit…. And we still need to discuss your incredibly lewd behavior of last evening. I will not have such disgusting antics in my home and will never accept or condone what you were doing to your own sister."
Richard could sense a false sense of bravado, and wondered just how far he could push his mother. He uncrossed his arms and entered the bathroom so he was standing a foot from her.
"Could it be that you are a little jealous of what I was doing to Robyn?"
"What?! Young man, I have never heard anything so ridiculous in my life. Licking another's private organs, where they urinate and have bowel movements is disgusting and no better than common animals. We are civilized human beings, and you will conduct yourself in such a manner."
Richard studied her as she was unable to meet his eyes and kept letting her eyes wander to his muscular bare chest and arms. He had to take the chance while it was offered to him, and quickly wrapped his arms around his mother and drew her body into his and kissed her deeply.
His captive mother gave a muffled scream and pounded on Richard's chest, but there was no escape, and as his tongue explored her mouth, she quieted her resistance and returned the kiss with great fervor. Her mind told her it was wrong to embrace your son, but her body responded to his advance as her hands traveled over his massive hard body.
