After eating they all went for a swim, and when Sue got out of the pool it seamed that the boys were staring even more. When she went inside to use the bathroom, she looked at herself in the mirror and found out why. Her wet suit was clinging to her like a second skin, showing the lips of her womanhood fairly clearly with no pubic hair to act as a buffer, and her nipples were prominently showing through the thin top. It excited her to realize she was turning the boys on but slipped into a pair of shorts and blouse as discretion demanded.
Over the next couple of days, Sue couldn't get the image of her son out of her mind. She would picture him naked diving off a cliff or swinging thru the trees by a vine, like Tarzan. When she lay in bed at night trying to go to sleep, she fantasized about him coming into her room from the shower with just a towel around his waist, and then she would drift into sleep and dream of Eric lying with her as they explored each other from head to toe. After much self examination and soul searching, she finally made the conscious decision to seduce her son and fulfill the desire burning within her. From a few comments she had over heard between Eric and his best friend, Ken, she was sure that he would be willing to make her dreams a reality.
The next Monday was June 17th, Eric's birthday. Sue made Eric a big breakfast and sent him off to meet a couple of friends at the mall. "Be back by one, I've got a surprise for you." His mom always made a big deal out of his birthday so he was sure it would be something nice. She had planed today months in advance, buying him a 05 Mustang convertible and storing in her friends garage. As soon as Eric was gone she drove to her friend's house and then drove the mustang home, pulling into their garage and closing the automatic door.
Eric parked in the driveway and bounded into the living room. "I'm home Mom. She came in and handed him a card. Eric opened the card expecting some hint to his birthday present but finding just a simple birthday card. "Okay Mom, where's my surprise?"
"It's out in the garage sweetie, come on, I'll show you." They walked out to the driveway and Sue stopped beside Eric's car. "I bought you something for your car." He had mentioned that he wanted a new sound system for his car and figured that he was about to get his wish. "Okay, close your eyes and don't open them till I tell you."
Eric closed his eyes and heard the garage door opening. When it stopped and his mom told him to open his eyes he found himself staring at the grill of a bright red Mustang with the top down and his mother dangling a set of keys from her finger. "Wow Mom how did you do this? It's too much, you really shouldn't have spent that much for a birthday present."
"Don't worry Eric; I sold some of those stocks your grandfather left me years ago. Your father has provided for me very well so I can afford it. Now, why don't you take your old mom out for a spin?" Sue had planed the car months in advance but had only planed the ride since the day of the pool party. She had worn a thin summer dress that buttoned down the front with no bra and the sheerest pair of panties she owned.
Eric moved his old car to the street and by the time he returned Sue was sitting in the bucket seat waiting for him. She had been thinking about her son almost nonstop since the pool party and finally decided to seduce him. Once they were out of town on a winding back road she unbuttoned the bottom three buttons along with the top two of her dress and waited for the swirling wind to do the rest. Eric was finding it increasingly hard to drive as he glanced over to see her dress open and expose most of her right breast or the hem blow up and give him a glimpse of her see-thru panties.
When Sue noticed the tented front of his pants, she said,"Why don't you pull off at that little clearing up there and we can get out and enjoy the view." Eric was enjoying the view just fine anyway but pulled over as she asked. When they stopped he got out trying to adjust his hard on while his back was to his mother. Then she said, "aren't you going to open the door for a lady?' As he opened the door, Sue threw her legs out of the door slightly parted and slid forward on the seat, pushing her dress up and exposing her panty clad pussy fully to her son. She didn't move except to hold out her hand to him to help her out of the car. Eric stood frozen for a few seconds looking at his mothers shaved mound, clearly visible thru the almost nonexistent panties. Finally her reached out and helped her up.
As she rose, her hand lightly grazed his hardened manhood. "My, My. It looks like I gave you two big presents today, do you mind if I take this one out for a test drive?"
Eric could only stand there speechless as his mother opened her dress the rest of the way showing him all of her charms before kneeling and undoing his pants ,letting them fall around his ankles. She wrapped her fingers around his rigid shaft and brought it to her lips, smothering the head with tender kisses, before slowly sliding her lips over the head and tickling the rim of his cock with her tongue. Sue could feel every vein and ripple of his cock as she worked him as deep as she could into her mouth. She reveled in the musty smell of his manhood and could count his heart beats as he pulsed in her wanton mouth.
"Oh yea Mom, suck me, suck my cock, it feels so good. Soon he felt his orgasm building in his balls and working up to the head of his dick. "Stop Mom, I'm going to cum." But Sue just increased the suction and speed of her attack. Eric was dumbfounded as he watched his mother swallow with every spurt of his cock, smiling around his shaft, her eyes locked on his as she pumped him into her mouth with her lips tightly holding the head and her tongue flicking over the tip.
When his softening cock slipped out of her mouth she asked "Do you want something to eat too?" She sat crossways in the car seat and pulled her panties off offering herself to her son. Eric dropped to the ground, his pants still around his ankles and gazed between his mothers wide spread legs kissing his way up the insides of her thighs, her womanly scent filling his nostrils as his tongue caressed her smooth hairless lips. When he got to her clit she moaned, "Yes baby lick it there, make your mommy cum baby, just like that. You make mommy feel so good Eric, I've missed this so much, you feel like heaven, make me cum." When she calmed down from an incredible orgasm she said "Eric, take me home so we can finish this in the comfort of our bed."
This was far and away the best birthday of his life, and the words 'our bed' let Eric know that it wasn't just a birthday present and he wasn't going to attend collage outside of town. There is a perfectly good collage fifteen minutes from his house and that's about as far away from home as Eric wanted to get for now.
