Billy looked up from the Television as his parents walked into the room. His father, Howard had his expression set in a stern gaze directed at his son. Beside Howard, Billy's stepmother Sharon stood looking a little nervous, her long legs crossed over each other as she waited for Howard to speak.
"Would you like to continue your lessons tonight?" asked Howard after a moment's pause as he briefly considered changing his mind again.
Billy swallowed, his throat dry. Two nights earlier his father had decided to teach Billy about sex and he had used his beautiful wife, Billy's stepmother as a model. Sharon had stripped off and let Billy touch her lovely 40DD's and then she had stroked his cock and then given him his first ever blowjob. When Billy had accidentally cum in her mouth his father had been furious and called the whole thing off. Now it appeared as though Billy might get a second chance.
"Yes, I'd like that," replied Billy, a little tentative, it seemed too good to be true. He glanced over at his stepmom. She looked as beautiful as ever, dressed in a royal blue dress that was reasonable short, displaying her long, tanned legs. The neckline of her dress dipped into her deep cleavage, all in all she looked as sexy as any supermodel or porn star. Billy felt the familiar tingle in his loins as he gazed at her, his mind briefly drifting to the blowjob she had given him earlier that day in the family car. His father didn't know about that and Billy decided it was probably best to keep it that way.
"Good," said Howard with a nod, "But if we do this you have to promise to behave yourself."
"Yes father," said Billy, his mind racing, was he really going to get to fuck his stepmother?
"And that penis of yours isn't going anywhere near Sharon's mouth," his father told him, "You abused that privilege the other night and you won't get another chance."
"Yes sir," nodded Billy immediately. After today's encounter with Sharon, Billy had a feeling that he hadn't seen the last of his blowjobs from Sharon, but right now he had his mind on something much better.
To Howard's surprise Sharon then took the initiative. Sharon was incredibly turned on by the way her husband was talking about her. The thought of being used by her stepson was driving her crazy with desire. Before he could say anything further she walked up to Billy and stroked his cheek. She then turned her back to him, "Can you please unzip me William?" she asked, indicating the zipper on the back of her dress.
Billy immediately reached up, eager to see Sharon's curvaceous body once again. He tugged down the zipper and the back of the dress parted, revealing the flawless skin of her back and no bra strap. As he pulled the zip all way down to just past her posterior he saw she also had no panties on, the upper swells of her buttocks and the crack of her ass visible.
"Beautiful," murmured Billy, still not ceasing to be astounded by his stepmother's fantastic body. He slipped his hands inside the back of her dress and briefly cupped her warm buttocks, giving them a firm squeeze before sliding his hands up her smooth back and pushing the straps of her dress of her shoulders.
Howard let out a short gasp as his wife's dress dropped in a pool around her ankles. She wore no underwear of any kind beneath the dress and the sudden sight of her full nakedness both surprised and aroused him. He was very tempted to cancel the lesson and take Sharon himself instead, but he knew that Sharon would be mad if he once again ruined it for Billy. After all Howard could have the gorgeous blonde whenever he wanted, this was Billy's only chance and Howard wanted his son to enjoy it. He would have to suppress his jealousy.
Still standing behind his stepmother, Billy reached around and pulled Sharon back against him, his hands reaching up and closing over the ample twin mounds of her generous tits. Sharon sighed softly as she let her lush curves press back against the young teenager, his hands eagerly squeezing at her tits while he pressed the urgent swell of his crotch into the bare globes of her ass. Sharon's hands rose and covered Billy's, encouraging him as he roughly squeezed and mauled at her big tits. Her nipples were as hard as bullets against his palms and her breasts felt huge, overflowing his relentlessly groping hands.
Sharon felt as though she'd never been so horny in her whole life. She leant her head back onto Billy's shoulder and slipped a hand behind her, going between their bodies to squeeze the lusty eighteen year olds bulging crotch. Billy pinched tightly on her nipples, tugging at her breasts and lifting them slightly up off her chest before releasing them and letting them jiggle free. Sharon rubbed her soft palm up and down between Billy's legs, distinctly feeling his hard cock. She so clearly remembered the addictive taste of his cum and the wondrous feel of his hard shaft sliding back and forth between her lips.
"Okay, come and sit down on the couch here please Sharon," said Howard, rubbing at his own throbbing manhood though his pants.
Sharon pried Billy's insistent hands from her tits and moved over to sit on the couch next to Howard. Her husband knelt on the floor at her feet and gestured for Billy to come and crouch beside him. Howard then took hold of Sharon's knees and parted her legs, leaving her pussy gaping like the centerfold from a Penthouse magazine. He saw the juices glistening on her pubic hair and knew immediately that she was turned on by the whole situation.
"This is your stepmother's vagina or pussy," said Howard, sliding one hand up along Sharon's smooth thigh and briefly brushing his fingertips across her pubic mound, eliciting a small gasp from his wife.
Billy reached up and stroked her with the tips of his fingers as well.
"Have a good look," encouraged Howard. Billy's fingers stroked the lips of Sharon's pussy, parting them slightly as he swiped a finger up the length of her slit. Sharon moaned softly as Billy rubbed the moist bud of her clit with his thumb and then he stuck his index finger up into her pussy. Sharon moaned as his intrusion.
"That's it!" said Howard, "Stick two fingers inside her."
Billy immediately obliged, his second finger probing within her.
"Oh that's nice William," breathed Sharon as Billy moved his fingers in and out, gently fucking her with them. "Would you like you put your penis in there?" she asked him. Billy looked up at Sharon with wide, lustful eyes.
"First things first," interrupted Howard before Billy could reply, "Taste her."
"What?" asked Billy in surprise.
"Lick her pussy," said Howard. Sharon twitched slightly in anticipation.
"Oh..okay," nodded Billy. He then put one hand on each thigh and leant in towards Sharon's cunt. His tongue darted out and he briefly lapped at her cunt. It tasted better than he had expected, kind of musty but not at all unpleasant or fishy as he had expected. Billy used the tip of his tongue to toy with Sharon's clitoris and she gasped in pleasure.
"Oh William!" murmured Sharon as he swiped his tongue up the full length of her cunt, tasting her.
"Okay, that's enough," said Howard, grabbing Billy by the shoulder and pulling him back away from her pussy. "I wouldn't normally bother much with eating a woman, they seem to like it but it tastes pretty bad," Howard told his son. Billy thought he actually liked the taste, but he didn't dare argue and ruin his chances of getting further with Sharon.
"Okay stand up Billy, and get undressed," said Howard as he moved back to his seat.
Billy did as he was told, standing right in front of his nude stepmother as he stripped off all his clothes very quickly. As soon as his large erection popped free Sharon reached out and took it in her soft hand. Billy gave a moan as Sharon's delicate hand stroked his hard cock.
"He's so hard," Sharon said to her husband, licking her lips at the thought of once again tasting Billy's wonderful cock. Or better yet, feeling it inside her. Billy's brief attentions on her pussy had her incredibly turned on and she had to do her best not to jump Billy right away.
Billy moaned, standing in front of his seated stepmother as she jacked him off, her hand moving rapidly over his cock.
"Please suck on my cock Mom."
"Certainly William," at his request, Sharon leant forward, licking the tip of his cock, Billy's penis lurched at the touch of her tongue and her own loins tingled as she tasted him.
"Stop!" snapped Howard angrily, the last thing he wanted was to watch his wife suck off his son all over again.
"Sorry Dad," said Billy, stumbling back a little as he remembered his father's previous instructions about his penis and Sharon's mouth.
"I said no more of that!" warned Howard grimly. Billy nodded obediently and Sharon scowled a little, first Howard had stopped Billy from licking her and now he had stopped her from sucking Billy.
"I'm sorry," repeated Billy.
"Well then," said Howard at last, "Let's get on with this, it's time you became a man. What position would you like to fuck her in?"
Sharon felt her heat rising in her loins, it must be something to do with her submissive nature but the way Howard and Billy were discussing her like a piece of meat was turning her on something fierce.
