You don't have a choice.

You both lie panting on the dusty road, half your body being crushed by her soft weight. Her head is pressed into your stomach so you can't see her expression. You may have pushed this far enough, so you decide it's time to extricate yourself and get outa here.

"So... that was fun. I guess it's getting late, so..." You gently try to push her from you, but her hands tighten on your shirt, forming fists and holding her in place.

"Not... not going 'nywhere," she gasps, slurring slightly. The potion couldn't have worn off already, could it? Her eyes rose to look into your face, and you see they are glazed with need, rosy patches on her cheeks, a few errant drops of cum dripping down her chin. "Need... more..."

She pulls herself the short distance up your body until she's kneeling, towering up over you into the sky, the sun forming a glowing halo around her plaited mane of golden blonde hair. Her hand snakes down and rubs your still sticky cock.

"Wow, okay, I may need a bit more recovery time...," you start, but are amazed to feel your cock immediately responding and inflating to its full size. 'Wow,' you think, 'this cock is the best!'

She ignores you and continues to stroke up and down your cock slowly, her hips matching the rhythm as her velvet vice-like grip sending sparks up your spine and burning out your brain. She slides her panties aside and rubs the head against her bald slit, groaning and shuddering each time it flicks over her engorged clit. One hand releases you cock and squeezes one of her full breasts, pulling and tweaking at her erect nipple in a way you'd think was painful but according to her face was pure bliss.

Finally, her eyes wide and wild, staring deeply into yours, hands either side of your head, she slowly splits herself in two as your cock begins to penetrate her. It feels like your member is being enveloped in a hot, gushing tunnel of pure electricity. You groan out loud as more and more of you enters her quivering quim. She, on the other hand, is muted by the over stimulation with a wide open mouth, eyes rolling back in her head, her body tense as she works you inside.

Finally, she can't take it any more and she drops straight down, impaling you entire length up into her warm soaking pussy as you hips slap together. You both moan as she hits bottom, the feelings overwhelming as you pause, unmoving, feeling how delightfully you are stretching her insides. Robotically, she lifts off of you until only the tip of your great tool remains inside her promised land, then she drops down hard again, screaming slightly and convulses, immediately having an orgasm, her pussy twitching around you. You would have cum in a second if you hadn't done so so recently. When it finally passes she starts fucking you in earnest, slapping her hips down onto you over and over, panting and moaning and screaming.

She starts a litany of begging of filthy comments and demands, such as, "Oh fuck that pure pussy!", "This dirty cock is so HUGE!" and "Cum in me... CUM IN MY CUNT YOU FILTHY MONSTER!"

You decide this passive lying around isn't for you and you grip her ass (all you can reach) and start thrusting up to meet her, forcing squeals of approval from her wild form.

Her tits and plaited hair are bouncing wildly as you slam into her, the crazed sound of the surrounding nature replaced with the slapping and grunting of your lovemaking.

You feel a tightening in your balls and sense your orgasm approaching. You slam harder and harder into her until she stops making coherent sentences and starts just screaming in pleasure. And then you explode, spurt after spurt filling up her insides as you scream victoriously to the open sky. She joins you in an earth-shattering orgasm, shuddering and shaking as her pussy clenches you so tight you fear you may lose your new dick.

After an eternity her eyes roll into her head, and faints on top of you, the pleasure sending her into overload. You pant, regaining a little energy, your head turned to the side to avoid being suffocated by the giant tits that barely missed smothering your head.

You should really get out of here because if your calculations are correct the lust potion should wear off soon and then you'll be a dead goblin when she regains her senses.
