Obviously Not.

Sally obeyed, her body trembling with a mixture of confusion and a strange, budding curiosity. She lowered herself onto him, the head of his cock pushing past her outer lips and stretching the tight ring of her entrance. She felt a sudden, sharp pressure, a feeling of being filled that made her breath hitch.

“Aaa!”

she cried out, her hands gripping the edges of the tub.

“nggh.. it—.. it.. hurts!”

“Just relax, my sweet..”

he whispered, his hands moving to her breasts, squeezing them violently.

“Just let me in~ Give in to ol Grandpa...”

With a slow, steady push, Sally sank further. The head of his cock pushed past the first ridge of her pussy, sliding into the warm, wet channel. The sound was a distinct, wet squelch, the air being pushed out of her as he entered her. The grandfather let out a guttural roar of triumph, his eyes rolling back in his head as he felt the incredible heat of her youth clamping down on his shaft.

He didn't wait for her to adjust. He gripped her waist and surged upward, burying himself to the hilt in one powerful thrust. Sally screamed, a high, sharp sound that was half-shock and half-pleasure. The **** of the impact sent her sliding back against the acrylic, her breasts bouncing wildly. The feeling was overwhelming; the fullness was an explosion of sensation that made her toes curl in the soapy water.

“Is—ngh.. is this the washing part?”

she gasped, her breath coming in short, ragged bursts.

“Mmh.. Yes,”

he groaned, his voice now entirely stripped of its grandfatherly facade.

“This— Ohh..mmm.. is the best part.”

He began to move slowly, his hips pumping with a sudden, renewed vigor. Each thrust was a wet, slapping sound, the noise of his balls hitting her plump asscheeks echoing in the small bathroom. Shlick, squelch, shlick. The water around them churned, the bubbles turning into a froth of sweat and saliva.

I can't believe I'm finally inside of her, after so many years. She's finally mine!

The grandfather's internal monologue was a storm of filth.

I've finally got her. I'm drilling into this little slut, filling her up with my old seed. Look at her, shaking like a leaf, not even knowing what's happening. She's so tight, so fucking wet. I'm going to stretch her out until she can't think of anything but my cock.

Sally's reactions were a blur of sensory overload. She felt the friction of his skin against hers, the way his wrinkled shaft seemed to grate against her tender walls. It didn't feel perfect; there was a roughness to it, a lack of coordination that sometimes caused him to slip. At one point, a particularly overzealous thrust sent him sliding out completely, the sound a loud, wet pop.

“Aaa..!?”

Sally exclaimed, blinking.

“You fell out, Grandpa!”

He didn't answer with words. He growled, his face contorted with lust, and slammed himself back inside her with a **** that made the tub creak. The impact pushed her cervix, a deep, dull ache that sent a wave of heat through her abdomen. Her round bubble butt jiggled and shook, each thrust sending ripples as they made the water bounce out from the tub, causing spills but neither of them cared. The old man leaned closer, his face slobbering against her perfectly smooth back, tasting the water and tangy bitter sweetness of her supple skin. Like a frantic monster in heat, trying to taste the innocence he's defiling. His arms hugging just underneath her large breasts causing Sally's chest to spill out and look larger then they were.

Squelch. Shlick. Squelch.

The rhythm accelerated. The grandfather was no longer pretending to be gentle. He was a man possessed, his hands roaming over every inch of her body. He pinched her nipples, twisted them until she whimpered, and then reached down to rub her clit with a rough, calloused thumb.

The combination of the internal pressure and the external friction was too much for Sally. She felt a tension building in her lower belly, a tightening that felt like a spring being wound too tight.

“Grandpa! Haah..I feel... I feel funny!”

she cried, her voice shaking.

“Do you— haah.. my sweet?”

he panted, his thrusts becoming shorter, faster.

“Tell me how it feels— Mmh.. so you hug me so good..”

“It's... it's like... a fire!”

she screamed, her back arching in a sexy yet innocent manner. The grandfather felt his own climax approaching. The heat of her pussy was like a furnace, squeezing him with every rhythmic contraction. It was so tight and perfect, an unused hole, a perfect body to go along with it. He could feel her beginning to cum, the walls of her vagina pulsing around him in tight, **** waves.

“I'm going to give you a real lesson now”

he hissed, letting out a final, strangled cry, his body stiffening as he surged one last time, burying himself as deep as possible. He felt the explosion begin in his balls, a violent surge of pre-cum and semen that erupted into her with a series of powerful, rhythmic spurts. He groaned, the sound a long, shuddering release that seemed to drain every bit of energy from his frail frame.

Sally collapsed against him, her breath coming in long, sobbing gasps. She felt the warmth of him filling her, a thick, viscous liquid that pooled inside her and then began to leak out, mixing with the soapy water of the tub. Her toes clenched adorably as her body twitched with every thick, creamy spurt that filled her stomach. Their bodies stayed connected for a solid minute, her supple white cheeks squished right on top of his old hairy lap as every few seconds she felt him pump a little more until his balls were completely empty. Sally left in a daze could only look up as her body was unknowingly claimed by her trusted family member, she could sometimes feel his rough kisses on his shoulder and back as they sat there together.

“Was... was that the soap?”

She whispered, her voice small and exhausted.

“Y-Yes..”

he panted, his voice returning to that soft, deceptive croon.

“That was the special cleanser, my dear. You did a wonderful job.”

He stayed inside her for a long time, enjoying the afterglow, the way her body continued to twitch around him. He felt a profound sense of victory. He had taken something pure and marked it as his own, all under the guise of a family chore. Slowly, he withdrew. The sound was a wet, sliding suction, a final squelch that left Sally feeling empty and cold as the air hit her wet skin.

“Now, go on and rinse off”

he said, leaning back against the tub with a look of absolute contentment.

“We wouldn't want any of that sticky stuff to dry on ya lovely skin.”

Sally stood up, her legs shaking. She looked down at herself, seeing the milky white streaks of his semen mixing with the bubbles on her thighs. She felt a strange, lingering warmth in her core, a sensation she didn't have a name for.

“Thanks.. Grandpa”

she said, her voice returning to its usual, innocent tone.

“Anytime, my sweet~”

he replied, his eyes already tracing the curve of her hips as she turned to rinse.

“Anytime at all~♪”

As Sally stepped out of the tub and reached for her towel, the grandfather watched her, his mind already calculating the next time he could convince her that she needed a special kind of cleaning. He knew she would come back. She was too trusting, too naive, and far too beautiful for her own good. He closed his eyes, the scent of her youth still clinging to his skin, and smiled a thin, wrinkled smile.
