Desc: Sex Story: Katheryn seduces her son's girlfriend with her son's blessings.

Kathryn was laying in bed, thinking about her son, Derrick. He was coming home from college tomorrow. She was ecstatic, after all she hadn't seen him in almost three months, not since his second semester of college started; which meant, she hadn't fucked him in over three months. He was twenty-one now and they had been having a sexual relationship for over three years. She wasn't sure why she desired or craved him as much as she did. She wondered, why is sex with him so much better than with any other of her male lovers? Maybe it was because she loved him more than any other person she had ever known. But, most mothers love their son very much; they just don't go around jumping his bones every time he come home from college.

Kathryn became aware that she was playing with her pussy; she didn't even know how long she was masturbating herself. Do I have it bad, she thought? I think of Derrick and I play with myself automatically. She realized she was wet, very wet and horny. She could see this was going to be a vibrator night. Kathryn wondered how many mothers masturbate to visions of their sons. Why did she need him so bad? Could it be because he's her son and that is one of the biggest taboos of society - sex with your offspring? She always got turned on by things that good girls didn't do. That's why she enjoys and embraces her bi side; again society believes it's wrong. Well what ever it was, she had very strong desires and urges for Derrick. She should feel guilty, but she didn't.

She was snapped back into the real world by the ringing of the phone. Kathryn answered it and found out it was Derrick. "Hi honey, I was just lying in bed thinking of you," said Kathryn.

"I'll bet your hand is between your legs now, isn't it mother?" Derrick asked.

"You do know your own mother. Why, yes it was," replied Kathryn. "Don't you masturbate, when you think of me?"

"All the time, mother," he said.

"Well, we won't have to masturbate much longer, you're coming home tomorrow and I'll have you all to myself. Plus, we're spending your spring break on the Gulf, just you and me. I hope we get out of our room long enough to get a tan," said a very happy Kathryn.

"Mother, that's what I called about," said a rather sober Derrick. "I won't be coming alone, Tiffany will be with me. Now before you yell, hear me out. It's really getting serious between Tiffany and me; she could be the one for me."

Kathryn said teasingly, "I thought I was the one for you?"

"Mother, you'll always be the one for me, Tiffany or no Tiffany, that won't change. However, I would like you to get to know her better and I thought this vacation would be the perfect time. Derrick continued, "Mother, we have been talking about my relationships, both with woman and with men. You always said you wouldn't stand in my way, but that you would like to be included in them, if possible. I thought this might be a good time to see if that's possible. We'll be together in one room in a motel for a week, anything can happen; at least I hope it can. What do you say mother? Shall we try to bring Tiffany into our relationship? She is sexy."

"Do you think it would work Derrick? I've always found her attractive, I'd love to see you fuck her or have her eat my pussy. Does she seam receptive to it?" asked an excited Kathryn.

"I don't know mother? When we watch porno flicks, she doesn't get disgusted when there it is girl-girl sex. She's even wondered out what it would be like to have a woman eating her pussy instead of a man," answered Derrick. "Maybe you can come up with a plan that may increase our chances of having a threesome."

"I'll do my best," said an excited Kathryn. "I'm still disappointed, we won't be able to fuck as soon as you come home, but it may be well worth the wait. Luv ya honey, see you tomorrow."

Kathryn lay in bed, thinking about her son's suggestion of a possible threesome with Tiffany. The more she thought about it, the wetter she got. She reached over and opened the draw of her nightstand. She looked at the three dildos and two vibrators lying in the draw, which one did she feel like? As wet and as horny as she was, she selected the largest one. She needed a big dick and this would do.

She fantasized about a possible threesome, while she fucked herself with the dildo. She imagined Tiffany eating her out, or better yet, Tiffany and her in sixty-nine position with Derrick watching and talking dirty. Yes, that's it thought Kathryn as she shoved the dildo in and out of her pussy. In her fantasy, Derrick is yelling things like; "eat her pussy, make my mother come. And lick her clit mother, suck her pussy, put your tongue into the hole I fucked this morning." Kathryn was working that big dildo in and out of her pussy much faster now, as she got more and more excited thinking about the possibilities.

She imagined a different scene, this one with Derrick on his back and Tiffany and her sharing his cock. She and Tiffany are taking turns licking and sucking his dick. Every so often, while they both are licking his cock; their tongues meet and they shared a deep French kiss. While Kathryn is fucking herself with her dildo, her other hand reaches down to her pussy, finds her clit and rubs it. She goes back into her fantasy. She visualizes Annie's hand reaching across her body and playing with her tits and nipples. Kathryn moves her hand up to her breast and plays with it the way she imagines Tiffany would touch her. There Kathryn was, lying on her bed, dildo buried deep in her pussy, her fingers at her clit and the other hand pinching her nipple. She was working up to a good come. Back in her fantasy, Derrick is jerking off as she and Tiffany continue their French kiss. Derrick's cock explodes, sending hot come right at Kathryn and Angie. She can almost feel the hot come droplets hit her face and neck. She can feel Tiffany's tongue touch her cheek and neck as she licks the come off of Kathryn's face. Kathryn's body shuttered as the orgasm hits her; it was a nice one, but not the big one she had been working hard to get, however it still felt good.

Her mind visualized another scene, one that had Derrick on his back with Tiffany sitting on his face and Kathryn riding his hard cock. Kathryn moved the dildo in and out of her pussy while in her mind she could see herself moving up and down on her son's cock. She looked over at Tiffany, watched her beautiful firm young breasts move up and down as Tiffany ground her pussy into Derrick's face. Kathryn visualized her son's tongue probing deep into his girlfriend's pussy. One of Tiffany's hands went to Kathryn's pussy to play with her clit; the other hand went to one of Kathryn's tit and began to squeeze and massage it. Kathryn's own hand went to her clit to mimic her fantasy. She pinched, rubbed, and squeezed her clit. In her fantasy, she was bouncing up and down on her son's cock while Tiffany tried to hold on to her tit and clit. Kathryn's began shoving her dildo in and out of her pussy very rapidly; she could feel the big one getting ready to rack her body. She pushed her fingers together, trapping her clit inside of them. Then, while her dildo was hitting places inside of her, where no cock had touched, she pinched her clit almost as hard as she could. That did it, her body went into spasms, she screamed and moaned, her hand was drenched in pussy juices and she blacked out for a few seconds.

When her orgasm subsided, Kathryn thought, I hope we can get Tiffany to go a long with a threesome. If it's half as good as my fantasies, we'll need a vacation from the week's vacation of fucking at the Gulf. Kathryn smiled at that thought, as she went to the bathroom to clean up. Just before she went to sleep, she came up with a plan on how to get into Tiffany's panties.

Kathryn woke up after a good night's sleep. It's amazing how a powerful orgasm will help you sleep like a baby, she thought. She took a shower, got dressed and drove to airport to pick up Tiffany and Derrick. She didn't have to wait very long before their plane landed and she saw them by the baggage area. When Derrick greeted her, she expected a little hug and a peck on the check, but he surprised her by giving her a rather passionate kiss on the lips in front of Tiffany. Tiffany gave her a hug and followed Derrick's lead and a kiss on the lips although it wasn't as passionate.

It took them about thirty minutes to get home from the airport. Derrick and Angie deposited their suitcases in his room and then they went out. Derrick wanted to take Tiffany to meet a few of his friends. It was late when they got back and Kathryn had already gone to bed.

The next morning Derrick was up and out of the house early. He had made arrangements with friends to go golfing long before Tiffany was scheduled to come along on his vacation. That would allow Tiffany and Kathryn a chance to get to know each other. They decided to do what women like to do, go shopping. They both could use a new swimming suit and some casual clothes for the vacation on the Gulf.

As they were walking through the mall, Kathryn stopped in front of a store that had big sale signs pasted all over the window. "Tiffany, lets go in here, I buy a lot of my work clothes and everything is fifty per cent off" Most of the clothes in the store were upscale, catering to the businesswoman. Kathryn and Tiffany walked over to racks of dresses. As they were looking through the rack, a rather attractive sales clerk approached them.

"Are you looking for anything in particular?" the woman asked.

"No, just some dresses or suits for the office. I saw you had a big sale so we came in," replied Kathryn.
