She saw him looking at her before thinking she hasn't noticed.
His attention shifted from the exercises he was supposed to do to her presence behind him.
As she leaned down supporting her weight on the support of the chair her hair touched his neck and cheek and her breast brushed against his shoulder.
That was too much for him.
His head turns and he kisses the corner of her lips and as surprised as she were by his action she closes her eyes and fight with conflicting thoughts then says softly one word:
"More"
He looks at her carefully and nods then place his lips on her and keeps them pressed for a fraction of the second before she takes the initiative and forces her tongue inside his mouth.
She closes her eyes and fiercly kisses him while he kisses her back and his hand travels upwards and moves under her shirt.
She smiles through the kiss and then moans surprised as he swiftly unfastens the front clasp and as her breasts are freed from confinement of her undergarment he places his hand on her tit and starts to gently knead on it.
She moves back and he looks at her a bit scared as if he did too much.
She takes few deep breaths looking at him and sees that.
She takes her shirt off and lets her bra slide down on the floor.
"Baby…"
He starts but she comes closer and cups her breast with one hand and places the other on his shoulder.
He only nods and looks at her with admiration and turns his chair then places his hands on her hips and pulls her closer and places his mouth on her nipple and starts to slowly suck on it making pleasant waves spread across her body.
She runs her fingers through his hair and  he pulls her closer making her sit on his lap.
She hugs his head while he alternates between sucking and nibbling on one breast then another while his hand rubs her from her neck to her lower back.
He moves his head a bit and looks up at her.
"Unzip your jeans"
He does his best to sound firm but the excitement is clear.
She endures the will to roll her eyes and whisper "boys" and does what he wants then presses his head agaist her boobs again.
He doesn't mind being smothered by them and grins and softly bites down on her nipple.
She gasps surprised as he pulls it with his teeth a bit then releases it with a loud pop and before she scolds him she whimpers as his hand lands under the hand of her panties and starts to rub her pussy mound.
A extatic gasp escapes her lips as he rubs her peach just above her clit and she feels through his pants his cock twitches in response to her voicing her pleasure.
She moves back and looks at him. He endures her look and looks at her back with a clear lust.
"You are amazing."
She moves back again and unbuckles his belt then grabs it and stands up.
Pulling him after her she sits down on his bed and unzips his trousers.
He places his hand on her cheek and leans down and kisses her.
She smiles through the kiss and he moves back a bit and slides his pants down.
She smiles at him lewdly and caresses his member.
He pulls his shirt up and she rubs his abs and chest then turns her attention back to his cock.
He takes of his shirt and takes off his pants and she flirtaciously bites down on her finger.
He leans towards her and she wants to kiss him but he pushes her back with an impish smile and takes her pants of her then after rubbing her slit through the fabric of her panties while keeping the eye contact he takes them off her as well and lays a wet kiss on her labia.
With her legs in the way he cannot see that she is biting down her lower lip as he buries his tongue in her slit and pleasures her.
She wants more.
She spreads her legs with her legs bent in her knees.
"Come here"
She says lustfully and he moves closer. She spreads her pussy and tubs it moaning a bit and he looks down to see what she is doing.
The display of her wet peach is making his cock twitch.
"I want you!"
He says with his cheeks all red and his chest waving, she nods.
She reaches for his member as he leans closer. His glans is all wet with precum and she leads him into her.
He lowers his hips and she wraps her arms around him as he moans as he delves deeper.
As he goes all in she nibbles at his earlobe and he kisses her while he starts to move.
He changes his tempo few times to settle for an intense strokes that make her feel waves of pleasure hit her every time her younger lover pushes in.
His arousal rises as soon as he penetrates her for the first time.
He dreamed of it for a long time and finally he has incredible girl under his thrusts that runs her fingernails through his back.
He looks at her face filled with bliss and keeps pumping then as he feels the pleasurable confinment of her pussy is reacting more vividly to his movements he picks up the tempo.
Her moans make his cock twitch and his panting is making her more excited.
They are both on a verge of cumming.
She looks at him with her legs slightly shaking and rubs her clit hard and closes her eyes.
"I am cuuuuuumming!"
She yells and he gasps victriously as he shoots his seed inside of her.
She hugs him and he kisses her neck while they are still connected.
"I hope you enjoyed it baby."
He whispers into her ear as they cuddle afterwards.
