Valentine used the pen for signing the document to coat around her wet juices.
Before slipping them in Riley's hands.
"Sign." She commanded, her lips brushing past Riley's lips.
Riley's eyes were low and filled desire. She held the pen, wet and coated with Valentine's warm juice.
The pen felt sticky on her hand as she immediately wrote her name, under the line provided in one shaky stroke.
Valentine didn't even wait for the ink to dry, she picked the contract file and threw it across the room.
"Done," she said in her low voice, almost proud. "Now let's make sure you never forget what you just signed."
Riley's breath hitched, but Valentine fine didn't allow her to recover.
She pushed Riley flat on the bed, shoved her legs open and Riley hooked her knees over Valentine's shoulders.
Valentine's beast bounced harder, the nipple still hard and erect waiting to be sucked. Valentine leaned in, nipples brushing Riley's mouth with every breath. Riley's own dress was bunched around her waist, panties already gone, pussy bare and already swollen from earlier.
Valentine held the pen up between them, letting Riley see it properly for the first time. It looked huge now, thicker than two of Valentine's fingers put together, the gold clip glinting like a threat.
A bead of mixed ink and slick hung from the tip and dropped straight onto Riley's clit.
It was cold for half a second then began burning as Valentine smeared it around with her thumb.
Riley's hips jerked. "Wait—"
"No waiting. Shut up and take it," Valentine said. "You wanted the contract. You take the seal."
She lined the pen up, the blunt, rounded cap pressing right against Riley's entrance. Riley had never had anything like this inside her, never metal, never cold, never something that wasn't fingers or tongue.
Her breath hitched. Her thighs tried to close on instinct, but Valentine's grip was like steel.
Then slowly, Valentine pushed it just deep enough to make Riley feel every millimetre. The lacquer was smooth but unforgiving, stretching her open in a way fingers never had. Cold metal sliding against hot, wet flesh. Riley's mouth fell open on a silent gasp. Her walls fluttered, trying to adjust, trying to take it.
"Fuck—fuck—too big—" Riley gasped, but her pussy was already sucking it in, greedy, soaking the pen in seconds. The gold clip bumped her clit every time Valentine shoved deeper and Riley saw stars.
Valentine watched her face like she was memorising every twitch.
"Feel that?" she whispered. "That's your signature inside you now."
She twisted the pen just a little, the ridges on the barrel scraping lightly against Riley's front wall. Riley's back bowed off the bed. A raw sound ripped out of her throat, half shock, half moan.
Then Valentine started fucking her with it.
Not gentle. Not slow.
She fucked Riley with the pen the same way she fucked with her fingers when she was impatient, fast, deep strokes that made wet, filthy sounds fill the room. Ink mixed with Riley's own slick, smearing dark streaks down her thighs, over the sheets. Every thrust pushed the gold clip against Riley's clit, sharp little jolts that made her cry out.
Riley's hands scrabbled at the bed, nails digging into the mattress. Her tits bounced with every slam, nipples so hard they hurt. The pen was thicker than anything she'd ever taken, stretching her wide, filling her so full she could feel it in her stomach. Cold metal turning warm, then hot from her body, then cold again when Valentine pulled it almost all the way out just to shove it back in.
"Look at you," Valentine rasped, voice rough. "Taking your own signature like a greedy little slut. You're dripping all over it."
Riley couldn't answer. She could only feel.
The slick drag of lacquer against her walls.
The wet squelch every time Valentine buried it to the clip.
The way her clit throbbed when the gold band rubbed over it.
The way her thighs shook so hard the bed creaked.
Valentine leaned down, mouth brushing Riley's ear. "Read the contract out loud, baby. Let me hear you say what you belong to."
Riley grabbed the contact with shaky fingers, tears already running down her cheeks.
"I—I belong—" A hard thrust cut her off, pen slamming deep to the clit and just stayed there, "—to Mummy—fuck—full ownership of—oh god—"
Every word came out broken, punched out of her with every stroke. Tears leaked from the corners of her eyes, mixing with the sweat on her temples. Her pussy clenched hard around the pen, trying to keep it inside, greedy for more even as it wrecked her.
Valentine didn't stop. She fucked Riley through every clause, every line, every promise, until Riley was sobbing the words like a prayer.
When Riley finally choked out the last line, "I exist only for Mummy's pleasure," her whole body seized up. Her orgasm hit like a slap, sudden and brutal. Her pussy clamped down so hard on the pen Valentine had to force it through the spasms, milking every pulse, every squirt that soaked the sheets dark.
Riley's vision whited out. Her back arched so high only her shoulders and heels touched the bed. A broken scream tore from her throat, raw and wrecked.
Valentine kept the pen buried deep, twisting it just enough to make Riley jerk with aftershocks, then slowly pulled it out. The barrel was coated with thick, black ink and creamy white swirling together. Valentine brought it to Riley's lips.
"Clean it."
Riley opened without thinking, tongue sliding out, licking the mess of ink and herself off the pen like it was candy. She tasted metal, salt, the faint bitterness of ink, and the thick sweetness of her own cum. She moaned around it, eyes rolling back.
Valentine watched her, eyes dark, chest heaving.
When the pen was spotless, Valentine tossed it aside. It clattered on the floor, leaving a wet streak.
She pushed Riley's trembling legs wider, settled between them, and looked down at the wrecked, fluttering hole still gaping slightly from the pen.
"Bedtime, toy," she whispered, voice soft now, almost tender. "Mummy's tongue hasn't tasted you yet tonight."
