Disclaimer: All names and places have been changed to protect the anonymity of the participants. My wife, Cathy is her fictitious name in this story, was 18 at the time of the events described. Her parents, whose fictitious names are Harry and Mary in this story, were 40. My goal is to assemble all the details Cathy related to me about this period in her life in a chronological order. How she became the sensual, uninhibited woman that I met when she was 35 was a subject we never tired of talking about.
The story continues...
Sex went from being a non-factor to the focal point in Cathy's life from that day forward. For the first time, Cathy felt she had discovered something she was really, really good at. Nothing in her life up to that point gave her such a feeling of confidence. Instinctively, Cathy understood the effect her body had on both Harry and Mary and how use it for effect. The multiple orgasms she experienced that first day also taught her that she absolutely loved sex. Seeing the lust in her Daddy's eyes was all the incentive Cathy needed to follow every instruction she was given with delight.
Mastering new techniques was easy for Cathy. Anything she could do to enhance Daddy's pleasure and, as a result, her own, created a desire to be great at it. That's what set sex apart from everything else in Cathy's life. She loved it, she was great at it and she had a burning desire to always get even better at it.
From that first time she stood naked in front of her Daddy and saw the lust in his eyes, Cathy realized she had a valuable gift-an awesomely hot body. Now lingering naked in front of her mirror (something she avoided up until now), running her hands over herself She could admire it in a way she never had before.
Daddy is right, she remembered thinking. My breasts are beautiful. Large, totally firm, cute pink nipples. Beautiful! Even at 18 Cathy had a womanly body, curves in all the right places, a shapely but firm butt and legs that were made to wear high heels and mini skirts. Looking at herself naked began to turn her on too. Masturbating suddenly seemed very natural. Cathy was on the same page with her Daddy. She was hot and she loved it too!
Mary had her hands full during the next few months keeping an air of normalcy around the house. Keeping Cathy focused on being the big sister instead of Daddy's insatiable lover took constant attention. Mary made sure Cathy didn't dress any differently or show any differences in her behavior towards Daddy. The secret had to be kept.
For Cathy, controlling it while going through the daily routine of school and helping Mom with the many tasks involved in keeping the other 4 kids fed, clothed and transported to their various after school activities required a lot of concentration. Acting like nothing was different when, in fact, everything was different was critical to the success of their arrangement. Mom, Dad and Cathy all worked very hard to make sure that there were no clues for anybody to think something was going on.
From Monday though Friday, Harry worked the 4-12 shift at the machine shop so he was around only for an hour in the afternoon when everybody came home from school. In that time before work, Harry too worked hard to maintain the facade that not a thing had changed. He spent the time talking with everybody, playing catch in the backyard with the boys if the weather was OK, enforcing the rules about chores, etc. just like he always had done. Cathy was just one of the 5 kids in the afternoon.
It was at 12:30 when Harry came home from work when the facade could come down. Mary could let Daddy and Cathy loose on each other. As Mary noted to Cathy, now Harry always has a big smile on his face when he comes through that door.
The mood for each night's encounter began to develop the moment Cathy opened her eyes in the morning.The glow she felt from being fucked so thoroughly just a few hours before was a wonderful feeling to wake up to Cathy remembered. Lying in bed touching herself, with images from the previous night flashing through her mind aroused Cathy's imagination in anticipation of how hot doing it all over again that night was going to be.
Harry and Mary's day started out the same way. Like a teenager, Harry woke up with an erection despite having come 2 or 3 times before sending Cathy back to her bedroom. Mary was thrilled to see this excitement in Harry and the happiness it brought to their marriage. Talking about the previous night and listening to the ideas Harry would come up with about what he wanted Mary to do to prepare Cathy for tonight always turned Mary on. Mary would alternate between stroking and sucking Harry's cock while they talked. Once the plans were finalized for that night, Mary would expertly suck Harry off and swallow his first load of the day.
Bedtime for the younger kids was strictly enforced at 9:30pm. As was her custom, Cathy would help get the kids to bed and then take her shower. Cathy's new custom now was to masturbate for the second time that day in the shower. Gently rubbing her clit with one hand and feeling her nipples with the other, it never took long to bring on a body shaking orgasm. Even then, one orgasm was never enough for Cathy. All she could think about after she came was how to get started on the next one. Leaving the bathroom and very quietly turning towards her parent's bedroom instead of her own, Cathy always knew Mary was ready to help her make sure the next one wouldn't be far away.
Now the mood changed from mild anticipation to full sexual arousal for Cathy. Mary too was aroused waiting for Cathy to come sit with her on the bed. Watching her beautiful daughter fuck Harry so well each night gave Mary a desire to touch Cathy in ways she had never felt before. Cathy remembered sensing within the first couple of days of their bedroom conversations that her Mom was turned on by her almost as much as her Dad was.
Their explicit conversations soon evolved into demonstrations of techniques that would involve Mary using a dildo and, soon, her mouth on Cathy. Feeling quite special, Cathy loved the attention from her Mom too. Listening to Mary tell her about how her Daddy loved something she did the night before (like the first time she 69'ed with him) or instructions about what Daddy wanted that night (like fucking her tits) made Cathy feel totally comfortable and excited about all of it.
Cathy estimated that it was within the first week when one of these demonstrations turned into Mary eating her. Cathy remembered standing in front of Mary with one foot up on the bed next to her. Mary was using the dildo on her to show Cathy how Daddy was going to fuck her standing up that night. The passion built so quickly that it seemed perfectly natural when Mary dropped the dildo and got on her knees and buried her face in Cathy's pussy. Cathy remembered holding her head with both hands and grinding her pussy hard against her Mom's mouth. The intensity of that orgasm left no doubt in Cathy's mind that being eaten was great by either sex. Kissing her Mom afterwards, tasting herself on her lips, Cathy felt so happy and content in her Mom's arms. From that day forward, lesbian sex became an important part of Cathy's life too.
As 12:30 neared, the ladies would assume their positions in preparation for Harry's arrival home. Mary would go downstairs to wait for him in the kitchen and usually Cathy would lay nude on the bed waiting for them to come upstairs. Harry and Mary would sit in the kitchen and talk for 5 or 10 minutes about the plans for that night and any last minute changes Harry might have come up with (like the night he decided he wanted Cathy to come downstairs and bend over the kitchen table for him). Usually though, they would walk into the bedroom, beer in hand, and lock the door.
As soon as Harry and Cathy saw each other, they both couldn't wait to start fucking. Cathy would tease Harry by touching herself while he undressed knowing he was already going crazy getting his clothes off as fast as he could. The sight of his thick, 8" cock, fully erect never failed to make Cathy eagerly assume the position Mary had instructed her to for their first fuck of the night. Whether she got on her knees or stood up or lay on her back, Harry would bury his cock in her and start fucking his hot, insatiable daughter like a dog in heat. No foreplay necessary. Their pent-up passion came out all at once in 10 or 15 minutes of seriously hard fucking. Harry would flip his daughter over, or lift her up off the bed like she was weightless and pin her against the wall while he rammed his cock into her or sit on the edge of the bed and bend her over in front of him so she could sit on his cock and let his hands guide her hips up and down on his throbbing erection.
Whatever positions Harry cycled her through the ending was always the same. Cathy's mouth on Harry's cock, swallowing every drop of his come.
