Final Chapter
Beth was lying on her back with her legs pulled back and she felt the head of head of her brother's well lubed dick press against her tight asshole. She stared longingly into his hazel eyes and felt the discomfort of his rough entry inside. She let out a slight hiss, but the discomfort passed quickly and she felt the fire inside of her.
She could feel her asshole stretch to accommodate Leo's large manhood and he easily got all of his seven inches inside of her. He let out a moan of pleasure as he felt the tightness press hard against him. Beth let out sighs of her own pleasure as he started to move his dick back and forth at a slow and pleasant pace. She saw the shadows start to transform and she knew he was about to change to something far more rough.
Her body was pinned and her knees forced further back, which left her wanting to shiver at the contact. His rhythm started to increase and his moans became something far more guttural. A shadow above her transformed into a female form with massive tits and lowered itself directly over her face. This time, her voice was silenced by a completely different type of lips pressing hard against her.
Her brother started to hammer away at her asshole and the iciness started to change to a pleasant warmth throughout he body. Beth's mouth was forced open and her tongue felt the edges of the lips. There was no scent or taste to go along with the feeling on her tongue, but she knew that would soon be rectified by a visit to her mother. Her tongue moved to the clit and she enjoyed the way the hardness felt.
Leo howled out as he reached his point of no return and Beth felt his release. He was as far inside of her as he could get and she could feel every twitch he gave her. Her asshole started to spasm around his large shaft and she tried to scream out, but there was only silence from her lips. Between each wave, her brother pulled back and then forced himself deep inside of her. Over and over again, he hammered her asshole with tremendous force, which caused her own pleasure to be increased greatly. She felt the pressure of her nipples being squeezed tightly, along with her clit and knew neither was from her brother's fingers.
Their orgasm started to pass and the shadows moved back, knowing they had done their job. She breathed deeply and felt him slowly remove himself from her dark hole. He collapsed on her bed and she wanted to lie there with him, but was far too driven not to move. She sat upright and saw the shadows enter her brother, all but the female form, and he showed the sign of feeling the iciness on his flesh for the first time.
Just as she was getting out of bed, Leo asked, "Where are you going, Beth?"
She said, "To eat mom's pussy. Get some sleep. Looks like you need it."
There was no hint of shock on his face at hearing her words, as he said, "Have fun. I'm staying right here. I'm beat."
She stood and felt a small amount of his cum drip out of her asshole and down to her thighs, which caused her to smile at the wonderful sensation. Even though she was leaving him behind, she could feel an important part of her brother buried deep inside of her asshole. She entered the hall and headed towards her parent's bedroom. The door was open and she could hear the pleasant sound of moaning from both of them. Shadows were working their way into the room, as if the sound of pleasure was drawing them from every corner of the house.
With no caution whatsoever, she entered their bedroom and saw her mother riding her father. She was sitting on him in a reverse cowgirl position, which meant her mother spotted her entrance immediately. Her mother's green eyes looked lustfully at her body and she was completely unaware of the shadows all around them.
Beth's eyes moved down from her mother's green eyes and to her bouncing tits. They were considerably larger than Beth's and knew she was going to have fun exploring them later. Her eyes moved down to her stomach and there was clear indication of being slightly overweight, which didn't bother her one bit. Continuing down, she saw a tightly trimmed bush, which resembled a beautiful red carpet, and wondered if she should do something about her full bush.
