"Permission to make you cum, babygirl?" I ask her playfully, earning a chuckle.
"Permission granted" She responds, clearly amused by my playfulness.
I kiss her lips hard before moving my way down, quickly unbuttoning her jeans and pulling them down with me. I take off her shoes and then slide her panties and jeans off her, throwing them in the chair beside me.
I lightly trail my hand over her thigh, separating her legs from each other, exposing her pussy to me. To my amusement, her pussy is already glistening. 
No surprise there, she's already wet for me. I know how much she's into me, but Jesus Christ, I love how I can see the effect I have on her. 
"You're already so wet for me, baby....." I whisper to her as I trail kisses on her thighs.
"And what are you gonna do about it......mommy..." she asks teasingly.
"Oh fuuckk, baby. You have no idea what that does to me..." I practically growl at her, feeling myself getting wet at her words.
I quickly bend down, sweeping my tongue between her folds, and collecting her fluids on my tongue before standing back up to kiss her. She immediately moans into me upon contact and quickly moves my hand to her clit to rub small circles into her. 
I hear her whimper for me, still adjusting to the sudden pleasure in her core. She holds onto my bicep, per usual, and grips me tightly while pulling me down to kiss her.
Me being me, I'm more than happy to oblige for my girlfriend, tracing her lips with my tongue and then dominating her own.
"Am I turning you on, baby? You like it when mommy takes care of you like this?" I ask her, sultry heavy on my voice.
"Mmhmm" she moans as her eyes roll to the back of her head and her grip on my arm squeezes me tighter.
"You look so pretty like this, baby....all spread out on your own desk for me...my body towering above yours as you hold me close with your leg around my body...." I whisper to her, trailing kisses along her neck.
"And you smell so fucking good, babygirl...sometimes I think you drive me wild on purpose..." I groan into her ear.
I suddenly sink my fingers inside her pussy, catching her off guard and resulting in her moaning loudly for me.
There's a little bit of resistance at first, her walls not fully relaxed for me just yet, so I pull out slightly before thrusting in again and again. I do this for a little bit until she takes me all the way, engulfing my fingers in her juices. 
"There you go baby.....just like that....mmm, yeah........oh, babygirl, you're taking mommy's fingers so well! I'm so proud of you baby!" I praise her as I pump my fingers in her soaking wet pussy for me. Her moans and whimpers are honestly turning me on so much more than I'd like to admit.
"Fuck, Taylor.....oh my god, you make me feel so good! Ugh!.....Yeah, just like that! Just like that, Taylor!" she moans, her voice sounding more eager than ever as it gets higher and higher.
"You're close aren't you, baby?.... Mmmm, look at you....my beautiful girl.....oh you're such a mess for mommy....you're a whimpering mess for mommy, aren't you?" I lightly tease her. She only moans more at my words.
"I'm so close, Taylor!.... Fuck, I'm gonna cum, Mommy!" she whines at me as pull her closer to the edge. I can feel her walls fluttering and clenching around my fingers the faster i pump them into her.
She's so close I can feel it.
"Mmm yeah? Are you gonna cum for mommy? Are you gonna cum for me, baby?..... Be my good girl and cum for me, baby!....be a good girl and cum on my fingers....cum on mommy's fingers, baby" I moan at her before kissing her lips harshly.
