She whimpers at the word, and I file that information away for later. I spin her back around, bend her over the desk in one smooth motion. That perfect ass up in the air, presented for me.
"Skirt up. Show me."
She reaches back with shaking hands, pulls it up slowly. No panties, just like I ordered. Her pussy is already glistening wet, swollen and ready for me.
"Spread your legs wider. Show me everything."
She does, spreading herself open. I run one finger through her wetness, gathering it. Bring it to her mouth.
"Suck. Taste how desperate you are for me."
She takes my finger deep into her mouth, swirls her tongue around it eagerly. My cock is so hard it hurts, straining against my jeans.
"You've been thinking about this all day, haven't you? Sitting at your desk, helping patrons, checking out books, all while knowing what was going to happen tonight."
"Yes, Sir! I could barely concentrate on anything!"
"Good. I want you distracted. I want you thinking about me all the time."
I drop to my knees behind her, spread her pussy open with my thumbs. She's dripping wet, clenching on nothing, desperate to be filled.
"Look at this perfect pussy. So wet for me already. So ready to be fucked."
I dive in without warning, tongue fucking into her, tasting how desperate she is. She slaps a hand over her mouth to muffle her moan, her whole body shaking.
"That's it. Keep quiet. Can't have anyone hearing what a slut the sweet little librarian is."
She clenches hard at the word again. Definitely something to explore more.
I work her with tongue and fingers, finding every spot that makes her gasp, every movement that makes her shake. When I suck her clit into my mouth, she nearly screams behind her hand.
"Please, Sir, I need— I'm so close—"
I stand, pressing my still-clothed cock against her ass. "Need Daddy's cock inside you?"
"Yes! Please! I've been so good, I've followed all the rules!"
"Say it properly. Like the good girl you pretend to be. Beg for it."
"Please, Sir, I need your cock. Need you to fuck me. I've been thinking about nothing else for two weeks and I need it so badly please!"
I unzip my jeans slowly, pull out my cock. Rub the head through her wetness, coating myself in her. She tries to push back onto me but I hold her hips still with an iron grip.
"Patience. You take what I give you, when I give it to you."
"Marshall, please—"
I spank her ass hard enough to leave a handprint. "That's not my name right now. What do you call me?"
"Sir! Sir, please, I'm sorry!"
"Better. Much better."
I push in slowly, so slowly, letting her feel every single inch as I stretch her open. She's so tight, hot and wet and absolutely perfect. I grind against her, making sure she feels how deep I am.
"This what you needed? Filled up with cock? Stuffed full?"
"Yes, Sir! God, yes!"
