Part 1
Sarah ran to her room on wobbly legs while the rest of the family busied themselves with the preparation of breakfast as though nothing out of the ordinary had happened. Well, it had, she thought; it most certainly had. How normal was it for a father to spank his naked grown up daughter across his knee, in his living room, with the rest of the family watching? Apparently it was perfectly normal in this family. What wasn't normal, and what she couldn't reconcile in her own mind was how this same daughter had had an enormous orgasm as she lay across her father's lap, as her father spanked her, as she rubbed herself on his hard cock. That would never be considered normal.
Throwing herself down on her bed, she covered her nakedness with the duvet and lay face down, her bottom cheeks still throbbing from her earlier spanking. The more she thought about it, the more embarrassed she became, the more humiliated she felt at the thought of her new step-mother, not to mention her much younger step-brother and sister, watching her being spanked and cumming on her father's lap. The tears were just about to pour from her watery eyes when she heard a quiet knock on the door.
"Can I come in, Sarah?"
Jill. What did she want? Sarah knew she didn't want to see anyone at that point, least of all her new sister who must have been shocked to the core by all that had happened this morning. Before she had a chance to answer, the door was pushed slowly open and Jill stepped into the room very tentatively.
"Are you ok? Father does get carried away sometimes."
Sarah wasn't sure if she was more stunned by the fact that this was obviously not the first spanking she had witnessed in her father's house, or mystified at the two bottles Jill was holding in her hands. Her younger sister noticed her staring and answered the question before it was asked.
"Whenever father spanks mother like that I always rub some lotion onto her bottom to ease the pain a little. Would you like me to do the same for you?"
Sarah's head was in a whirl. Her father was in the habit of spanking his wife? Her younger sister was in the habit of watching this take place? And then she rubbed her mother's punished cheeks, her naked cheeks to ease the pain? She didn't know what she was more embarrassed about but her sister showed no trace of being embarrassed by any of it.
"No thank you, Jill. That won't be necessary. If you could just leave me alone for a little while, I'll get dressed for breakfast."
"Oh please, Sarah. Let me do this for you. I really want to get to know my big sister. Maybe if we started with a shoulder massage, you'll relax a little."
Sarah was just about to insist that her younger sister leave the room when she suddenly wondered if it was Jill who had left the incriminating photo on her pillow earlier. Sensing the older woman's hesitation, Jill smiled to herself and, without further ado, or before Sarah could say another word and free her arms from under the quilt, Jill eased it down off her sister's shoulders and had begun to pour some oil from the first bottle into her hands. She gently began spreading it across the other woman's shoulders and back; Sarah found herself actually relaxing under the firm but soothing presence of her younger sister's hands. When she realised that Jill was actually quite good at this, she allowed the young girl to draw her arms out from under the duvet and extend her massage up her arms, kneading each muscle with her sisterly touch. She felt very exposed lying there, naked under the quilt but, as long as Jill's hands went no further, then she felt it would be all right.
Seeing that her older sister was now more compliant, Jill moved down the bed and quietly uncovered Sarah's legs, not hesitating before beginning to work her hands up and down them. Sarah tensed as her legs were revealed but couldn't deny that her younger sister seemed to know exactly what she was doing. Gently lifting the older woman's legs apart further, under the pretense of gaining access to the muscles on both sides of the thighs, the younger girl knew how close she was to her prize; she wanted another long look at her older sister's red cheeks and, if she was lucky, she might even get a peek at the bald pussy lips between Sarah's open legs.
Sarah was unaware of her sister's ulterior motives but she knew it felt very, very good having those young hands push and squeeze the muscles in her legs. If she wasn't careful she could start to enjoy this and she was afraid her body would betray her all over again and that would be even worse than what had happened in the living room on her father's lap. When Jill's hands slowly pushed the quilt up further so that it was now bunched around her older sister's waist, both women gasped when the older woman's punished bottom came into view, Sarah in humiliation, Jill in amazement. Her older sister's cheeks may have been sorely dealt with but they were still magnificent, round and firm. Without hesitating, Jill took the second bottle, the one with the soothing lotion, and began to softly, shamelessly, knead her sister's firm cheeks.
Sarah felt embarrassed lying there, naked but for a duvet around her waist, but this was exactly what she needed. Her cheeks were still throbbing from the beating they had received from her father and, even though her face was as red as her bottom, she couldn't help but let out a low groan of pleasure. Jill couldn't have known that the groan was almost sexual, Sarah assured herself, but she realised that the soft hands on her poor cheeks felt so good and she was sure her arousal was beginning to rise ever faster.
Maybe she should have put a stop to it there and then but when she felt those small hands run down across her cheeks, the two thumbs keeping close to the inner curve of her bottom, she had something new to worry about. Seemingly unaware, Jill continued her movement downwards and brushed her hands over her sister's pussy lips, one thumb definitely stroking the other woman's clit. Stunned, Sarah tried to close her legs but her sister's purposeful hands were now working back down her thighs. She couldn't have closed her legs even if she had wanted to.
Just as she had convinced herself that it had been an accidental slip and that she shouldn't make too much of it, she felt Jill begin to press harder with her thumbs, feeling them skilfully work on the inside of each thigh, rubbing in circles, teasing her older sister as she began to move back up, higher and higher.
