David goes along with it, for now.

"Hmph! w-wait! " David could barely think as his eager cock already started flooding him with overwhelming sensations.
Her sensitivity peaked up, her own lust and desires by far overriding his own.
"Wait for what sweety?" she giggled, "My body feels sooo good!".
"Fuck, this is too much for me" complained David.
"Its ok baby, just relax and enjoy the ride." his cock reassured.
David could feel his cock burning with need, it throbbed powerfully and strained hard, almost to the point of pain.
He could no longer resist, and at this point he wouldn't want her to stop even if she let him choose to.
His hand instinctively reached and wrapped around his cock as in his usual routine.
She moaned loudly as he wrapped around her, but then she left him dumbstruck as she strongly pulled herself away from his hand - "Listen baby, don't take it the wrong way but.. I kinda grew tired from your hand. I want to do other things!".
David at that moment couldn't care what she wanted, he just wanted it to be over with, "Whatever just get it over with" he almost begged her.
But this was exactly his attitude that she didn't like, she loved to take her time, to enjoy every small touch on her body, every small sensation that her sensitive body produced, it was her way to feel alive.

She thought to herself, she knew what she wanted to try.. she pointed at his face with lewd ideas.
She knew it wasn't the right time, David needed more time before they could get.. 'closer'.
"Hmm, ok! Hold your knees and bring them towards your chest, then tighten your thighs around me" She said happily as she twisted herself to point at his thighs.
There was something extremely hot and empowering about instructing David what to do, she felt much more significant than the body part she was supposed to be.
"Shit, alright.. just hurry up, we need to get going soon" he said as he entered her requested position.
She looked at him happily, smiling to herself with her success and control over the situation.
She was so excited, anticipating the moment he closed his thighs around her.

Both moaned in unison as he did.
David watched as his cock wasted no time and started rubbing herself between his thighs.
She was right, it did feel amazing.. much more soft than his rigid hand.
His thighs felt like pillows, it was probably the closest thing to an actual tit-fuck.
Despite feeling everything she did, David felt completely left out, he could only watch and feel his body shiver as his cock moved all on its own in an erratic and unnatural way.
His cock was in a world of her own now, feeling the bliss of sexual interaction.
David was completely fascinated by watching her erotic body and hearing her wild moans and dirty talk as she went.
Not even in porn he saw a woman that enjoyed herself that much.
And here David had her attached to him, enjoying herself as if nothing existed in this world but her.
He never felt so close and intimate with a girl, never heard someone moan right next him as a result of sheer pleasure.
And there she was, such a confident and sexual female presence that not only accepted the male pleasure, she also urged him to make the most of her.

It went on and on, nothing short lived as David hoped for.
His mind was going blank as she kept shifting between gently pressing against his thighs and fucking them, coating them with her pre.
The wet sounds accompanied each of her movements.
"Gah, I need to cum!" David moaned in deep need for release.
His cock of course shared his passion for release, but decided to prolong the endeavor.
"Soon baby, soon!" she almost screamed between his legs as moans followed by.
"I can't hold it anymore, I have to!" David urged her.
"Fuck!" she cursed, "Ask me for it" she commanded him.

"Just cum!" David pressed on.
"Beg me for it baby!" She screamed in her pleasure as she shifted to aggressive fucking again.
"Shit! Please, please please please let me cum!" David pleaded.
She couldn't help but smile at her success, her dominance in this situation pushed her over the edge as she felt her eruption imminent.

It was extremely tempting to cum directly at his face, to faster make him come to terms with her cum which she was sure wasn't terrible for him as he described.
But for now she had her desires fulfilled, she thought as she powerfully tucked herself between his thighs one last time and pumped her cum between in what felt like eternity of bliss.
"Oh! Oh! oh GOD!" David cried to his core as the pleasure was too much to bear.
He nearly passed out again, instead - he was shrouded in euphoria.
