Fast, hard and right fucking now, that's how!

It seems like both you and Erin find your patience breaking at the same time as, almost as though at some unspoken signal, you both move to each other quickly and fall upon each other like hungry animals. Your lips crush together as you kiss her hard and she kisses you right back, your tongues swirling and undulating against one another as you moan into each other's mouths. Your hands move to her hips, pulling her against you tight and her own long, powerful arms wrap about your shoulders, one hand coming up to tangle fingers in your short blond hair while the other grips your shoulder tight to hold you close.

Your bodies pressing together as they are traps your rigid prick between your bellies, your own flat belly and her defined abdomen squeezing that thick rod between hot flesh in a way that has you shifting your hips in need. This doesn't go unnoticed as her hand in your hair slips down to wriggle between your bodies and grasp that hot throbbing length against her. As her hand closes around your thick cock, her hand accomplishing what no other lover you've had before could by completely wrapping around your girth, you hear her gasp in lustful sensation. Her breathing had already been hard and growing harder and hotter with every moment, but it seemed like her actually grabbing your cock sent her lust shooting upwards as she kisses you all the more hungrily and begins to rock her hips against you in a needful way.

You realize, in a dim and faraway sort of way, that this is probably the effect of the aphrodisiacal chemicals exuding from your hard dick that your father had told you about, but you hardly care right now. As hot and hard as you are, you couldn't care less about how or why Erin was so hungry for you. All you cared about was satisfying that hunger that you both had. That raging lust that, perhaps, had been caged for years without your even knowing it...though Erin, by her own admission, had known of her own lust very well before now. She was only just able to unleash it now.

She seemed **** to unleash it completely as she began to tug on your monstrous shaft with small short pulls of her hand and rotations of her wrist. Her simian attributes made her limbs all the more flexible than a normal woman's and so that rotation of her wrist made her stroking of your cock all the more smooth and pleasing to your senses. Adding to that the way her breasts pressed against your chest so tightly, her rock hard nipples scraping against your skin, and the way her tongue continued to dance sensually with you own, and you knew that you couldn't hold back much longer.

And then she broke the kiss and brought the hand on your shoulder up to wrap about the back of your neck and grasp you by the back of the head firmly as she pulled you close so she could whisper into your ear. "Young master, please, please...I want you inside me.", she whispered heatedly to you, "Mate me, young master. I want your seed inside me..."

The needy, panting way she pleaded for you to take her was the last straw and, with a groan of aching desire leaving your lips, you grabbed Erin by the shoulders and pushed her backwards roughly. She gasped as she took a few steps back and her ass bumped into a lab table behind her. You didn't give her time to question your actions as you closed the distance between you once more, your hands moving to her hips and, with surprising strength from your lithe frame, you lifted her up so that she was sitting on the table. The movement sent a number of notes and lab supplies falling to the ground, but you couldn't care less as you pushed Erin down onto her back on the sturdy lab table, her legs hanging over the edge of it as they splayed apart so you could stand between her thighs.

That posture put her soaking wet pussy on full display to you, her delicate flesh pink and tempting as it glistened with the proof of her arousal. You could smell the arousal from her sex, her animal nature making the scent pungent and heavy in the air. You found that arousing as hell as well and you licked your lips as you grasped your own fat cock and positioned yourself at Erin's entrance. The swollen head of your rod prodded at Erin's slit and, only then, did you hesitate. Despite her large frame, her pussy looked as tight and small as any other woman's. You feared, right then, that you could hurt her if you let your lust run wild and you hesitated...but then you felt Erin's fingers against your cheek tenderly to draw your attention.

"Master, please.", she pleaded as she met your gaze imploringly, "Take me. I was made for you. Take me as you wish."

That invitation snapped any last bit of restraint you had and, with a firm nod, you shifted your hips forward to slide your prodigious erection inside of Erin's hot, slick cunt. She was tight around your inordinately thick prick, her inner walls hugging your rigid flesh as you penetrated her, but it did not seem to be painfully so. No, there was no cry of pain from Erin. Instead, she moaned throatily and you felt her hands at your hips as she pulled you forward.

"More, Master. More, more, more...", she moaned out rapidly and excitedly as she pulled you forward, forcing more of your hard dick inside of her.

You had intended to go a bit slowly, but she had different ideas it seemed and, shockingly, she pulled you into her with one hard pull. And, even more shockingly, you actually hilted yourself within her, something you'd never been able to do before. The new sensation of being fully engulfed in a tight, heated pussy all the way to your root made you give your own throaty moan and it was joined by Erin's breathless cry of pleasure at being so perfectly filled as she now was.

"Ah, yes. Yes, Master. You...see? I was...made for you...", she panted out and then rocks her hips against you as she lifts her hands to clasp behind your neck as she looks up into your eyes lustfully, "Now...take me..."

You didn't have to be told twice and, as you lean down to capture Erin's lips once more with your own, you draw your cock out of her and then slam it back in hard and fast. She cries out against your mouth as you begin to fuck her hard and fast, loving the feeling of filling her up again and again. She seems to love it just as much as she pants and moans out in ardent pleasure as you fuck her pussy without restraint. You feel her legs wrap about your waist, her feet grasping at your hips like hands due to her gorilla traits, and she urges you to go faster and harder with the pulls and presses of her legs.

Soon enough, you are well and truly pounding her cunt, her body jolted with every slap of flesh on flesh that makes her breasts bounce enticingly. You can feel the table rocking beneath her body as you violently take her on it and part of you dimly wonders if the piece of lab furniture can actually take much more. But that's something you put aside as you continue to drive your dick inside of the welcoming embrace of her pussy over and over until Erin is gasping and her body is going taut against you.

"M-m-master. C-c-cumming!", she groans out just as she wraps her arms and legs around you tight and grinds herself against you, her hard clit against your pelvis as she rotates and wriggles against you as her orgasm hits her. She loses all her breath and she shudders against you as her inner muscles flutter around your thick cock, trying to milk your dick for all it's worth as she groans in pleasure. You feel almost like you could join her in her climax in that moment...but should you or do you still want more?
