The movie which had just started as Carol and Pam arrived at the glass door to watch was also specially made as a porno documentary over several months by two women who were running an animal rehabilitation unit and hospital in the Zambian jungle. They had a few natives who came for parts of the day to help, but who were used to being told not to come or to go early if there was not much work to be done. A veterinary surgeon was on call by plane from another hospital about two hundred miles away. Both women were expert with the cameras, having filmed each other fucking the local chief without him knowing, as well as filming many of the hospital procedures for training films (the official reason for the camera).

At their centre was a mature gorilla who would probably never return to the wild. When he was brought into the hospital his mouth was badly damaged, they assumed in a fall, and most of his teeth had to be removed to repair his jaw, so he would find it difficult to forage for himself as he needed fairly soft foods to survive. Over the eighteen months he had been with them he became very quiet and tame, although he was always kept in his cage and had a leg chain fitted for if he ever had to be restrained for further examination. Robyn and Dianne were now quite happy to walk into his cage to feed him, and had trained him to sit, clap, shake hands and to let them feed him from their hands to his mouth. One afternoon as Robyn was passing his cage on her way back to the house she noticed he was sitting on his wooden bench playing with his prick in his lap. She stopped to look and was surprised by the size and jet blackness of what was usually only a very short stubby appendage almost completely covered by hair. It was still only partly hard but was already impressive. When he looked up at her Robyn said in the cooing training voice she used to congratulate him when teaching him his tricks "Gooood boy, Gooood boy Mumbles", and she called Dianne to look too. He seemed to lose interest just as it fully hardened, but Dianne had time to praise him too for his effort. As they walked away the girls formulated the beginning of a plan to see if they could train the huge animal to use his excellent prick as they wished and directed. That night they called the vet on the radio and suggested he send the young female who was now of breeding age he had at his hospital to see if they could mate her with Mumbles before releasing her back into the wild. The vet agreed and himself flew the light plane with the doped female to the outpost. They put her in an observation cage in the hospital, far away from Mumbles' pen.

"Its getting late", Dianne said to Graham the vet, "Why not stay the night? have a shower and freshen up while we get some dinner."

Graham agreed, he had stayed often before and been visited in his bed during the night by one of the girls intent on removing every last drop of cum from his body. That was why he flew over, it had been about six weeks since he had fucked Dianne, so he figured it would be Robyn who would ravish him tonight. His prick tingled at the thought as he let the warm water from the outdoor solar shower trickle refreshingly over his sweaty body. The tingle in his prick soon became an almost fully hard erection while he imagined Robyn sitting on his prick and riding him home as he lay back and enjoyed it. His reverie was broken by Robyn's voice.

"You decent?", she said as she opened the slit in the hessian shower surround and came in, "Not half bad at all" she continued, her eyes focussing on Graham's shaft as it swelled in her presence, "Looks like you're after something to do tonight Graham."

He looked at her dumpy body which she had squeezed into a stretch skirt and a tight boob tube that barely covered a fraction of her ample bosom. Folds of suntanned tit oozed out top and bottom of the garment, causing Graham's shaft to jump with excitement.

"Seems you're glad to see me big boy" she said as he dragged her close and hugged her tightly.

The warm water running on them both wet her clothes.

"Would you miss dinner for a good screw Graham?" Robyn asked.

Graham answered by reaching down and running his hand under her skirt. To his surprise it slid, unhindered by any pants, straight into her slippery slot. Robyn quickly removed his hand and replaced it with his cock, rubbing herself sensuously onto the hard shaft.

"The deal is", she said wrapping her arms around his shoulders, "You have to fuck us both, do as you're told, but not say a thing until we're both done. Got enough cum in those hard balls for the two of us???, you haven't been over for ages and we both miss you."

She felt his rod answer with a lurch between her legs, so she wiggled enough to let the end of it just open the entrance to her lusting cunt. Graham grabbed her bum in his hands and forced it further in by crouching slightly to get a better angle of entry. Robyn jumped off, stopped the water, and taking him by the prick led him into the kitchen where Dianne was starting to prepare their meal.

As Robyn entered leading Graham, she said to Dianne:

"This prick says instead of dinner he wants to fuck us both, and he won't speak, and he'll obey our every instruction till he's made us cum at least once each. What do you reckon, Dianne???".

"What if he grunts when I squeeze his balls?" Dianne asked, "Does that count as speaking?".

"S'pose not, What do you think Graham??"

Graham grunted, nodding in agreement with Robyn. He had decided he could have a great night with both girls at once, and if that meant not talking and obeying them, his prick wasn't about to miss out on a golden opportunity. Robyn let go of his prick and told him to sit on a seat she moved out from the kitchen bench. When he put his feet on the stool ledge his knees were fairly high and apart, leaving his prominent prick jutting out proudly in full view. Robyn walked around behind Dianne who still had her shorts and khaki work shirt on.

"Perhaps you should see what is in store for you Graham. Stay on the seat till we tell you to get off now like a good boy", Robyn said as she started to unbutton Dianne's shirt from the top.

"Only felt these tits eh Graham?, never seen them though. What do you think they look like?" she continued as she fully opened the shirt revealing Dianne's suntanned torso with her boobs covered by a light almost see through white bra.

Dianne's nipples puckered hard against the material as her excitement level increased looking at Graham's pulsing shaft while Robyn nibbled her sensitive ear lobes making her squirm. Graham noted the effect of Robyn on Dianne's ears as his shaft hardened even more at he sight of Dianne's hard nipples. Robyn took a glass of tepid water from the bench and poured it gently onto Dianne's bra, revealing her breasts fully through the wet cloth. Graham was now stroking his cock in anticipation of the pussies to cover it that evening. Robyn decided to assist his quest by pouring some olive oil from the bottle onto his prick so his fist would slide more easily along the hard length of his turgid member. Then she slid Dianne's shirt right off and undid the bra and removed it also, setting free Dianne's firm globes from their daytime prison. She oiled her soft hands and started to slide them over and around Dianne's beautiful sun-browned tits while still nibbling her ear lobes from behind. Dianne winked wickedly at Graham and slid her right hand into her shorts and started to caress her willing clitoris to further heights while she suggestively sucked the first finger of her left hand into her warm moist lips. The pressure in Graham's prong was enormous, both because of his sitting position and the sight before him. He groaned loudly and squeezed his shaft harder as Dianne's hips started thrusting erotically at her fondling fingers.

Dianne knew she would have to have Graham's lovely rod deep in her cunt before too long. The sight of the nice hard prick, the sweat on his face and Robyn's ministrations to her tits and ears, coupled with her expert fingering of her own clit had her very close even now to an energetic orgasm.

Robyn realised what was happening but wanted to make Graham wait quite a bit longer for his chance to make them cum. Letting him near Dianne now would be too easy for him.

"Let's make him watch and then he can try later when he's ready to explode" Robyn whispered very quietly in Dianne's ear so Graham didn't hear.

Then she lowered Dianne's shorts and knickers, revealing a bush of bright red that matched her fiery short cropped hair. Dianne's hand didn't miss a beat as Robyn walked her towards Graham. Robyn lifted Dianne's right leg onto Graham's left knee, fully opening her moist slit to his eager view. His eyes were less than a foot from her wonderful cunt lips, but he was told to keep his hands to himself.

While Dianne continued with frigging her clit, Robyn slipped one hand under her arse from behind and poked two fingers into Dianne's slippery pussy as her thumb worked gently at her weakening arsehole. Robyn's other hand still flicked wickedly at Dianne's oiled tits and she continued her oral assault on Dianne's erotically sensitive ears. She ran her thumb into Dianne's slippery cunt to lubricate it, and as Dianne's body relaxed at the commencement of her orgasm, Robyn plunged her thumb as far into the waiting arsehole as it could go and rubbed it against the two fingers she had in Dianne's convulsing cunt.

Dianne's reaction was so violent that she nearly fell over as orgasm pulsed through her body, heightened by Robyn's hand work and the sight of Graham's mighty rod surging as he watched her in admiration.

"Well, my boy" Robyn said as Dianne leaned against the bench panting from her exertion, "You look like you're about to shoot your bolt. Can't control yourself when there are girls around eh??", and she bent forward in front of him, hitched her almost non existent skirt, and spread her feet so he had a full view of her moist glistening pussy.

Graham could feel the tingle in his balls that signalled an unstoppable orgasm had commenced and he knew he would spray his milky fluid all over the place in less than a minute. Dianne, realising the problem, reached down, and grabbing his prick in one hand and holding Robyn bent forward with the other, she shoved his thankful penis head between Robyn's cunt lips.

"C'mon slave, fuck her deep!", Dianne ordered.

Four strokes of his throbbing shaft and he flooded Robyn's hot cunt with his creamy cum. His knees buckled as he ejaculated and his rod slipped out and shot a sticky squirt on Robyn's face as she watched between her legs.

"Four lousy fucking strokes, is that all you can manage fly-boy ??" Robyn jeered as she licked his cream from her lips, "You haven't made either of US cum yet and it looks like you're finished for a while".

Graham was by now so horny it was hard for him to not speak, but he maintained his control and grabbing Robyn by her boob tube led her into the lounge room, pulled the tube down around her belly to free her wonderful boobs and lay her lengthways along the back of an easy chair so her clit was pushing on the upholstered ridge. He quickly slid his aching shaft into her cum soaked cunt, forcing her clit hard onto the ridge and sending tingles of delight through her body.

As he shafted away at Robyn's pussy, Dianne came into the room leading a male chimp by the hand. When the chimp saw Robyn's bare breast dangling down the back of the seat he sat down and took the nipple into his nimble lips and started to suck and caress it with gusto. While he sucked and Graham prodded Robyn's cunt harder at the sight, the chimp spread his knees to reveal an erect prick of modest proportions which he started to fondle with his free hand. Dianne assisted him by spreading a handful of hand cream on the hard cock for him so his hand would slide easily over the blackish shaft. Then she went to the back of the chair beside Graham and Robyn, and with her creamy hand started to massage Graham's balls from between his arse cheeks. She used the fingers of her other hand to hold Robyn's arse cheeks wide apart so Graham could watch his prick sliding in and out. Robyn's winking asshole fascinated him as it puckered in time with his penetrating prick. He noticed Robyn's right hand had taken over on the chimp's prick while the chimp fondled his own balls with one of his feet.

Graham's fascination with Robyn's arsehole turned to a definite desire to plunge his rock hard penis far inside it and flood her with a seminal enema. He indicated Robyn's arsehole to Dianne by pointing at it. Dianne nodded her head and spread a liberal coating of cum from Graham's previous ejaculation around the intended victim. She loosened the muscles by gently working her finger in to full depth over about four minutes by keeping time with Graham's prick as it slammed hard in with each stroke grinding Robyn's clit against the chair ridge. He slipped his cock from her pussy and gently nudged the tip of it into her well prepared arsehole.

When the tip was easily in he slammed the full shaft quickly in and forced her trembling clit deliciously against the chair. Robyn could feel the eruption begin somewhere deep inside her being as Graham's frantic rhythm crushed her against the ridge with each wonderful bowel bulging stroke. Her stroke on the chimps prick increased furiously and in return his efforts on her right tit added to her euphoria. She groaned, grunted, yelled and bucked violently back at each plunge of Graham's surging cock.

"Aaaarrrrggggghhhhh, aaahhhh you eeerrrggghhh horny arse-fucker, that's ooohhhh uuurrrgggggghhhh aaaaaaahhhhhhhh ooooohhhhhhhheeeeerrrr" Robyn grunted as she vibrated on the end of Graham's prick.

The chimp let go of her boob and lay back on the chair as her hand brought him to a high spraying ejaculation while he beat his chest and howled in erotic glee.

Robyn's shudders and jerks slowly subsided. Her low moan was punctuated by grunt each time Graham's inward stroke up her arsehole slapped his thighs against her slippery bum cheeks making her breathe out.

Graham moved her back a bit with her legs about two feet from the end of the seat so he could crouch a little and punch hard to his now inevitable explosive ejaculation.

Dianne moved behind him and started massaging his balls again with her left hand while beckoning to the chimp with the other. She directed him under Robyn's belly at the end of the chair and started her magical arse fucking with her finger on Graham's sweaty arsehole as she had done to Robyn earlier. Graham was in a euphoric state just waiting for the flood of seminal fluid to surge up his thrusting cock and flood Robyn's bowels. She started to push against him as the chimp, sitting under her, covered her pussy with his mouth, pressing hard on her clit with his upper lip while he snaked his long nimble tongue deep into her cum sticky cunt. The chimp's hairy lower lip tickled Graham's balls as he plunged harder into Robyn's arse with each stroke. He could feel that wonderful sensation of the sperm leaving his balls and shooting up his prick to spray wantonly into Robyn's anal orifice. Her muscles closed firmly on his cock as his ferocious thrusting and the chimp's agile mouth brought her to a second noisy orgasm.

Graham moaned too as his now cum covered cock slid even more easily through her tightly clenched arsehole. When the second flood of fluid started up his shaft he pulled Robyn's arse tight against his cock and gleefully pumped the next four or five spasms of sperm deep into her warm bowels. His knees were about to buckle from the exertion so he pulled his cock out and stood straight up. When he looked down he saw a stream of his creamy fluid running from her winking arsehole. As it reached the chimp's lower lip and ran in, the clever animal moved his tongue to follow up-stream to the source, and Robyn's body shuddered as the agile tongue probed for entry at her now tightly shut hole.

Graham slumped into the chair, his pole still rigid and jerking, with small trickles of cum spilling from the eye of his prick with each jerk. As his breathing slowed his penis started to deflate and sunk shining against his thigh. Dianne came over.
