Tease her more

You can't help it. Seeing Emily leaning up against the wall, her tits out, doesn't immediately inspire you to make her cum. It's the endgame, but it's a bit off. Instead you lean forward and gently lick and tease her left nipple, feeling pucker and harden even further. Your lips stay glued to it, and Emily moans. She looks down at your face and you can tell she wants to say something. You gently pull off, leaving her tit quivering on her chest.

"John," she moans. "Why won't you put that finger in my pussy?" She gives a sexy smile, and your mouth moves to her other breast. "Not again," she grunts, but her hand pushes the back of your head onto her already stiff tip. The nipple fills your lips, and you decide to inhale a bit more of her breast, but still leave room to tease her swollen nipple with your tongue. She seems to love it, whimpering as her hands slide down your hand. You catch her right hand going between her legs, and gently pull her wrist to her free breast. "I can't even rub it myself?" she asks.

You pull off her tit and put her other hand on her breast. Emily begins squeezing her tits, teasing her nipples as she looks at you. "You like the show?" she asks. You grin and kneel in front of her. She grunts and groans, actually bouncing her right breast as she anticipates your next move. You lean in, tongue slowly creeping out and gently lick the inner thigh of her left leg.

"Ohhh. You asshole!" she cries. She releases her left breast to cover her mouth and looks down at you pleadingly. "Please," she murmurs. You turn to kiss the inner thigh of her right leg, peppering it with feathery taps of your lip on her skin. "Please make me cum." The sound of her begging is an enticing one, and so you move your mouth to just above her pussy and begin kissing and licking her skin. Emily bucks gently, but her hand releases its tit, and her hands begin running through your hair. "Why are you so fucking good at this?" she asks.
