An endurance test

In a flash, the Gorilla doctor has mounted you and put your cock deep inside her cunt. A deep moan echoes from the back of her throat, indicating how much she enjoyed the sudden invasion.

"So, Doc," you grunt at feeling the heat of her cunt. You hold her hips to keep her steady. You don't want to blow your load too early. "What's the first thing on the list?"

"Hmm," The Doctor smiles as she rolls her hips, threatening to make your groan again. Maybe it's you, but you could swear that your dick is reaching deeper than it did when you fucked the Queen. "I was thinking of an endurance test. Just to set the base. Interested?"

"Hell yeah!" you grunt.

Taking charge, you roll the Gorilla Doctor onto her back and plunge yourself into her as deep as you can possibly go. She squeals in surprise, but that melts into deep moans as you plunder her pussy mercilessly. You're sore from having sex so many times in one day, but there's no way you're going to tell anyone that. Not when there are so many needy Ani-women out there. After all, it's your duty as their new stud and king to keep them sated.

"Keep going!" the doctor pants. "We haven't even hit the half-hour mark yet!"

You don't need a timekeeper thank-you very much! If she's looking for endurance then you'll just have to surprise her. You dive down into her humongous boobs and suckle her black nipple. She cries out and groans loudly while grinding her hips against you, hoping for deeper penetration.

"The other one!" she moans. "The other one too!"

"Doctors orders," you grunt before you take a free hand and grab the remaining breast. You squeeze and pinch the fleshy formation, much to the Doctor's delight, before finally pinching the nipple and tugging.

"Mnnnnn!" she groans. She wraps her legs around you, using her lower feet/hands to grope your butt. "Shit!"

You feel your limit approaching. It wasn't going to be much longer before you explode into the good doctor. Going for broke, you hoist her up so you're on your back and she has to bounce on top of your cock. She groans tiredly, but her tune soon changes when you use a hand to begin rubbing her engorged clit.

"FUCK!!" she screams at the top of her lungs, her tunnels clamping around your penis desperately begging for sperm. She gets it too as you finally unload into her depths, filling her womb with the white fluid.

She collapses onto you, almost smothering you with her abundant titflesh. She breathes heavily for a moment before lifting herself up by her arms and looking down on you.

"Not bad," she smiles. "But we have lots more tests to do."

"I'm ready when you are." You grin, reaching up to massage the simian breasts in front of you.

"Good, because I plan to keep you here for a while," the Doctor smiles seductively.
