Happy Birthday to the source of my Nom-de-plume, Roger Caesar Marius Bernard de Delgado Torres Castillo Roberto (1 March 1918 – 18 June 1973).

Late Lunch

Sheldon is in his office, pondering neutrino energy states when there is a knock on the door.

he frowns, not expecting anyone, then shrugs. "Come in."

Penny pops her head round the door. "Hey honey, you busy?

"Gravity never ceases . But in the sense I assume you mean of "can I pause momentarily without harming my work", no I'm not busy"

"Good good, as I'm invoking the monthly Spontaneous affection clause"

She slides in balancing two lunch trays. "I thought it would be nice to have lunch together "

She gives him a playful grin as she sets the trays on a side table, drops her shoulder bag and shuts the door. She's got her hair pulled back in a loose ponytail and is wearing her sky blue tight vest top, a short denim skirt and sandals.

Sheldon carefully tidies his notes into a folder and shuts his lap top. Time with Penny was a nice distraction from his current challenge and a change of focus often helped. Plus he noticed she locked the door when she closed it.

She turns around slowly, puts her back to the door and winks "Plus I've been missing you. "

He catches a scent of green apples. Recalling her schedule, he asks. "just finished Yoga class? "

She walks round to his side of the desk and sits on the edge, her legs straddling his.

"Yes, all limbered up and freshly showered for you"

She grins and stretches out, hands over her head, slowly wiggling side to side.

Her short top rides up, and he watches with interest as she flexes her abs for him.

He strokes his finger tips over her stomach then down, over her skirt and along the inside of her toned thighs. she murmurs happily and spreads her legs wider.

"maybe we could have some private time for a little fun?"

He rolls his chair closer and pulls her down into his lap, taking her face in his hands and Kissing her, his tongue parting her lips.

He's learnt the art well, he can recognise the changes in her body better than she can, even if he still can't read faces. His guile less honesty cuts through her charm and self delusion, he knows when she needs light or loving or playful or sensual, and he does it whatever she says.

He'd explained his theory late one night as they lay in a post orgasmic hug.

"I aim to satisfy your needs first, then mine. Then my wants, then yours" the idea still gave her a horny little tingle, he would see she got what she needed not what she wanted.

What she needed now was him.

Her morning yoga work out had been fairly light but she'd been distracted, thinking of Sheldon watching her as she stretched out or curled on the mat, fantasizing about him touching her as she moved, his hands on her breasts, in her hair, forcing her into positions as he strokes her cunt open, ready to throw her down and fuck her senseless.

By the end she realized she was panting , looking in the mirror her face was flushed and her nipples straining her sports top. She was glad she had dark yoga shorts as she was wet with excitement.

His kiss gets rougher, more demanding. He grabs a handful of her hair in one hand, the other going up her shirt. Her breast filled his hand, her hard nipple under his thumb. He squeezed, making her moan and press against him.

Sheldon took great delight in the feel of her. Before he'd never understood the pleasure tactile stimuli could hold . He could tell she was turned on, and a horny penny was a pleasure to tease. She'd sometimes get like this, usually from dreaming up some delightful fantasy and it was a source of pleasure to him to charm or torment it out of her. Sometimes she'd whisper it into his ear to turn him on, but others she would feint shyness and he would have to force it from her, making her squirm and blush as she confessed her horny little secret.

Shes got a building knot of excitement, a quiver in her thighs. She feels the need to grovel, to beg, to get down on her knees before him and offer herself for his pleasure. The thought of taking his cock in her mouth makes her wetter, remembering the taste of him on her tongue as she worked her clit with two slick fingers makes her squirm. Huskily she asks "want me under the desk?"

Instead he stands, lifting her so her ass is on his desk edge, her skirt up around her waist. he grins, as he suspected she's not wearing any underwear.

"No, on it. " He pushes her back, over the desk.

"Grip the far edge. Do not let go."

"Yes sir."

She leans back, spread across his desk.

He picks up two pencils from his desktop, the pair held together top and bottom with rubber bands. He pushes his finger and thumb between then, stretching the bands. Then with that finger and thumb he grips her nipple, taking a cruel twist of sensitive flesh. She moans and arches her back but doesn't let go of the desk edge, even when he flexes his fingers and the pencils slide off, the bands pulling them together and clamping her nipple between them .

The hot pain if his grip is replaced by a dull throbbing ache . She's always had sensitive nipples and it has become a favourite torment of Sheldon's, as he knows he can stop her coming with the right pain or drive her harder with a tug and a tease . By the time he clamps her other nipple she's panting, both nipples throbbing and aching in time with the wet heat twisting in her gut.

She looks him in the eye them looks away, biting her lip then begging "Fuck me please Sir"

He unbuckles his belt and unzips his pants, she can't see but she feels his hard cock spring free, it thuds against the lips of her cunt, heavy and engorged.

He pulls his belt free, makes a loop and drops it over her head. His left hand rubs her open, spreading her wetness ready for his cock as his right pulls it tight on her neck.

she feels a stomach tightening frisson of fear. She knows what he wants to hear.

"I'm yours. Take me. Make me. Ah yes, Sheldon, I'm yours" As she's moaning her plea he thrusts forward, sliding into the slick wet heat of her as he's tugging the impromptu leash, using his weight to pin her ass to his desk. He thrusts hard and fast, eager to claim her. he pulls her to him as he thrusts his hips, driving deep into her .

She bites her lip to not cry out, loving the feel of him in her. She wraps her legs round him, wanting him more, harder, deeper.

Held in position by his words, tormented by her aching nipples and hours of needing this she gasps, about to explode.

He rapidly doubled the belt over and shoves it in her mouth as she gasps. "Bite down. Come for me but come silently"

She almost cries out in frustration at the cruelty of this new bondage, her orgasm was when she felt the most free. The fact he'd taken that freedom from her so suddenly made her sob as the first orgasm shook her, the taste of leather and the firmness as she bit down in helplessness drove her further, his grip on her hips, his thrusting cock, all overwhelmed her.

Gripping the desk in desperation she came for him again, the wave of raw sensation wracking her with a wretched sob. She threw her head back, tugging the belt tight as she felt him thicken and swell, loving and hating how much she suddenly needed this. Then he took her breast in his hand and squeezed, massaging the throbbing ache of her clamped nipple as he came and she lost herself , wailing through gritted teeth as she came again.

Her thoughts are fuzzy. She feels him slide out of her, wrap his arms around her, wrestle her death grip from the desk edge. She feels sparks and sees stars as he pulls the pencil clamps gently free. He sits down on the floor, with her lying on him, her face pressed to his chest. he un-loops the belt from around her throat and holds her while she floats, shell shocked. After a minute or two her eyes refocus and she manages a breathless "Wow"

"How do you feel?"

"Wow. Just Wow." She nuzzles up to his chest and kisses his neck "helplessly owned and deliciously ravished, Sir."

He holds her more, stroking her hair. "seems we found a new secret pleasure of yours"

She laughs softly. "guess I leveled up?"

She gets unsteadily to her feet, getting a towel and panties from her bag.

"You hungry?"
