Doctor Gorilla's Enema

You've given the doctor a good fucking and the two of you are tumbling about a bit on the bed, kissing, licking, grabbing, and generally having a lovely time. With her enthusiastic attentions, it's not long before you're up again. The doctor slides her big simian lips over the head of your cock and begins to suck you while feeling you all over with all of her prehensile appendages. You grope at her boobs and pussy before you begin to lube up her ass with juices from her cunt. She groans and gasps around your cock as you finger her ass.

"That feels incredible," she says, "I've read about anal sex, naturally, but was totally unaware of how sensitive that area is. Anal penetration doesn't happen much in nature."

"Well, maybe I should give you that enema we spoke of earlier," you say, grabbing at her big ass cheeks.

"Mmmmm...," moans the doctor, "I'm game...let's just see if it fits."

Between the doctor's wet slurping and the juices from her pussy, there's definitely a good amount of lubrication. Still, as she gets on all fours and presents herself to you, it's questionable just whether or not you'll fit in there. Still, you aim to try. You line yourself up with the doctor's puckered anus and slowly begin to ease in. The doctor hoots and growls in pleasure and then deeper you go, the louder she gets. She's so tight in there and soon you're fucking her, holding onto her wide hips and giving her the full length each time. Soon she's slamming herself back against you and with one of these moves, you fall to your back with her on top of you. She doesn't stop and continues to bounce her ass on your cock. As you're in this position, you reach up and grab her massive boobs from behind. Soon the doctor is cumming, squirting all over your thighs, and you blast her ass full of your cum. The two of you stay in that position, gasping for a moment, before the doctor lifts herself off of you only to shift to a position where she can kiss and lick your body up and down.

"Wonderful," she moans, "very very healthy."
