It really wasn't fair his dad was old and she was well Hot! Not hot for forty Meredith was just plain easy on the eyes. Shouldn't matter to him right he would be off to college at the end of the summer but he couldn't stop thinking about her.
In fact he spied on her every chance he got he had almost seen her naked once but the housekeeper almost caught him, oh well. Today however they were alone, dad was away on business again and the blasted housekeeper was not around either. He had an idea and he couldn't let it go, for a month he had been planning ways he could have sex with his stepmom.
He had been flirting with her in an 'innocent' sort of way and had gotten flustered if positive results. Now he just had to get in his step sisters pants and he would have her. The key was the teddy bear Helen had which he knew the nosy woman had put a spy cam into, to make sure the brat didn't have sex in the house.
If he seduced Helen, Meredith would come running then hell he might just get to fuck both of them. Now his dad couldn't say he had done that. Helen should not be too hard to get with she was horny as fuck and he had spied on her masturbating more than a few times. Now that he thought about it he might miss this when he left.
He bounded downstairs to look for his step sister. Helen was his age short with bleached blond hair just like her delicious moms. She was sunbathing in the backyard by the pool when he found her. God this was going to be fun. He had already started to lay the groundwork on her too since the whole devious plan had popped into his head.
She lifted her head and smiled at him as he got close he beamed back. "You bored?" He opened.
She laughed that annoying laugh he hated so much and said "Of course." he grins as her gaze falls on his crotch. Too easy.
"Want to have some fun behind mom's back?" he winks at her. She goes a cute shade of pink and huffs as if his cock is the furthest thing from her mind.
He knelt by her "Come on you know you want to we both know you haven't had any for a while."
She is beet red now and she looks away "Fuck no! You perv" he is undaunted.
"You have been grounded all week I know you need it." she starts to look but hesitates. He is sure he has her but he has to be careful not to move too fast just yet. He gets her sunscreen and starts to rub some onto her back she stiffens but as he goes she relaxes again seeming to enjoy the attention.
He whispered in her ear "I want to fuck you Helen and you are going to ride me like the sex starved slut you are." Shit that was too much she would punch him in the dick any second now.
He braced and waited but the blow never came instead she had started to breath out of rhythm. Holly shit it worked she was into it. After a moment he whispered again "Come on let's go to your room quickly before she spots us." He got up and to his delight so did she. He grabbed her hand and they took off for the house. The coast was clear and they made it to his sisters room no trouble.
Once inside he shut but did not lock the door even if he made it look like he had. He saw her look around as if she was having second thought. He had to nip that in the bud so he advanced on her in his most alluring way. She snapped around her full attention on him as he reached out and caught her arm and pulled her in to him.
She might be nervous but she did not resist, good. He kissed her tasting tacky lipstick yuck still all for a good cause she would wipe it away on his cock soon. He felt her break away and suck in air. "There, see you are going to like this aren't you?"
She blushed and smiled "Ya sure." her eyes were back on his crotch and he guided her hand to touch his rising penis. She bit her lip and started to stroke it. Damn he was fully ready now and started to undo his shorts.
They dropped to the floor as she got to her knees. Fuck this was going so well. He felt her free his cock and continue to glide her soft pampered hands over it. She definitely knew what she was doing damn why hadn't he done this sooner he thought.
Now her mouth was opening and her little pink tongue slid out to taste him. After a thorough examination with her tongue she took him in to her mouth an inch at a time. He wound his fingers into her hair and pulled her closer she moaned softly around his dick and made sucking sounds as she began to work her mouth up and down him.
It felt amazing to have her there servicing him knowing his step mom could see the whole thing. He let go of Helen, she was fully into it now and was deep throat-ting him. Winking at the nanny cam he took off his shirt.
He wanted to give Meredith a show before she got there. He was on the edge now and knew he should stop his step sister soon if he was going to enjoy the whole plan.
A little roughly he pulled Helen up to her feet she was very reluctant to do so and complained about it as he grinned at her. She shut up as he cupped her small breast in his left hand. With his free hand he reached around and undid the bikini string along her back the top slid forward and his hand rearranged to be under it massaging her hard nipple. Then he undid the last string and the whole thing fell away. He knelt down so he could take her nipple in his mouth and sucked at it.
She gasped and pressed against him, he slid her bikini bottom down around her ankles and stood up. He easily picked her up with only a small protest and deposited her on the hideous girly bed. He looked at the hidden camera willing his step mom to come find them. She squealed in anticipation as he lay her back. Looking at him hungrily she wiggled enticingly, he thought what the hell and leaned down to see how wet she was and was pleased to see she was dripping for him.
He licked her pussy and heard her make happy noises at him. His tongue went deeper then flicked up against her clit she shuddered and pressed her hips against his face. He stopped after a few minutes and sat on the bed next to her he had lost only a little of his erection while looking to her pussy and he wanted it back. She took the hint and help out with her mouth again.
Soon as it was fully hard he pushed her mouth away "Ride it" was all he said. She sat in his lap legs around his waist and lowered herself onto him. She was tight and warm around his cock and he thrilled to be in her. Slowly at first then steadily faster she rode him moaning and rotating her hips in a practiced manor. He held her close enough that he could catch her breasts in his mouth if he wanted to but not so close that he couldn't watch the door for stepmom. She had better hurry he thought this slut in his lap was good at what she did. He had underestimated his little princess of a sister.
Then she was there red faced and yelling he laughed to see his stepmom burst into the room like that. His sister screamed and tried to jump out of his lap as if that could hide what they had been doing. He held her in place and looked at his stepmom. "Hi" was all he said to her through the tirade of condemnation spewing from her. She marched across the room and moved to slap him but in a swift movement he pushed Helen out of his lap and caught his stepmoms wrist as she let fly.
A look of surprise over took the anger as she found she could not pull away. He held her wrist tightly enough to hurt and slowly got up still very erect and wet from Helen's pussy. She couldn't help it, he saw her gaze drifted to his cock even as she demanded he to let go.
Out of the corner of his eye he could see his step sister hugging her knees on the back corner of the bed. She was of no importance right this moment but would add to the fun again soon. His attention was on Meredith, just now her big tits heaved as she started to try and pull away in earnest. "Stop." he commanded, she did more out of surprise then obedience.
