"I want to cum like that, what can you do for me??", Dianne panted.

Graham waved his hands and pointed to his mouth, showing he wasn't speaking, as ordered.

"Fuck Robyn's silly game, you can talk now", Dianne giggled as she squeezed his slippery pick and it popped out of her hand still floppy.

"I thought we could be the main event, I've been dying to see what you look like while I,m fucking you Di. That was just an entree to the main course.... you and me" he whispered quietly in her ear.

"What are you two whispering about?" Robyn panted, still feeling the delicious tongue of the chimp probing her sensitive arsehole for more of Graham's cum as it trickled out with each diminishing spasm of her ebbing orgasm.

"I said I need a drink and a good feed before I will be able to do her any good at all" Graham lied.

Dianne went to the kitchen and putting on an apron she quickly cooked steak and chips for them all. Before she finished cooking, Graham's rod became interested in the sight of her shapely body, especially from behind as she bent forward revealing her magic crevice to his lustful eyes.

They ate well and finished a couple of bottles of wine with the meal. By ten thirty, Robyn, who had finished another bottle of wine by herself, dozed off as they watched the end of their third film of the chimps and other animals screwing and masturbating. Graham and Dianne had already started on each other as they sat watching, and Robyn had even poured some wine on his rod and licked it off for him before she started to nod off. When Robyn dozed off Dianne got out the film she had taken of the chief fucking Robyn with his impressive shaft. Graham's shaft responded as Dianne had hoped it would. She had been getting progressively hornier remembering Graham's words about waiting to fuck her as the main event. If Robyn's orgasm was just for starters she wanted what was to come next. Graham reached over and took two big bananas from the fruit bowl and then led Dianne to the room with the big bed. The chimp followed as Graham waved the bananas at him.

"I'll show you a trick I saw the native nurse we have at the hospital use to get herself ready for a good fuck, you sexy cunt you". And he peeled a banana and gave it to the chimp to eat. Then he peeled the other and as the chimp watched in expectation of another treat, he slowly slid the firm fruit into Dianne's horny pussy. She wondered what he was up to, but the feeling of the banana slipping into her vagina sent little tingles of erotic sparks through her body. Graham left about an inch of the large banana sticking out of her pussy. Then he took the chimp's hand and moving him towards Dianne's banana filled twot pushed the hairy lips onto the short piece of jutting banana. The chimp responded by using his lips and tongue to try and eat the soft fruit.

The effect on Dianne was instant and electric. Waves of carnal delight pulsed through her sexually receptive body as the soft lips and tongue caressed her creamy cunt. Not wanting to miss out completely, Graham straddled Dianne's face and pressed his cock between her panting lips. She responded by swallowing it deep into her throat, and waves of erotic excitement pulsed through Graham while he watched the chimp's long tongue probing deep into the quivering cunt in search of more banana. When the chimp realised there was no more banana he ceased probing the slippery orifice and sat back watching Graham while his cock pistoned in and out of Dianne's lips. All the fucking she had been watching, added to the meal, the wine and the chimp's recent tongue fucking had Dianne ripe for an explosive orgasm. Graham slid his knob from her mouth and nestled it between her cunt flaps ready to penetrate her cavern of pleasure. "I can feel you starting to tremble sexy Dianne. See what this does for you", Graham whispered into her ear as he slowly slid his waiting penis into the warm moist pussy she thrust towards his throbbing flesh.

The glorious feeling of the cunt folding tight around his prick as it entered Dianne's slippery sleeve of delight was enough to warn Graham that very few strokes would be needed before his balls started pumping his milky fluid into Dianne's womb. At the same time the feeling in Dianne's cavernous cunt as the thick dick spread the lips apart and expanded her vaginal walls while it penetrated her, and the wonderful feeling of his short and curlies pressing her clit flat against her pubic bone, all combined to start her bucking with the beginning of her sweet climax.

"Shove that in harder and fuck me stupid" she yelled, startling the chimp who was happily fondling his dark prick. "Pump me full of your fuck juice you horny fucking pilot, let those balls flood my fanny." And she locked her legs behind his back to grind him harder onto her delirious clitoris while she floated into another world where cunt was king. Her whole world was centred between her legs as Graham's seed started to seep from around his pulsating rod while her cuntal contractions milked his prick greedily into her body.

The next morning Graham had to leave early. Dianne wore nothing to breakfast and they both promised to send him the film of Mumbles fucking Tess when it happened. Over the next few days the girls wore very short skirts around and made sure they bent in front of Mumbles at every opportunity. They also encouraged him to fondle his prick at as much as possible. Robyn had even started to handle it herself when she went in to feed him. He seemed to enjoy the game now, as she used a slippery hand to harden it for him, but he always lost interest after it got hard. There was other work to be done, but they did only the absolute essentials and spent the rest of the time on their number one project, Mumbles' prick. They had fed the female gorilla extra hormones to bring her quickly into heat, and today was the first day she had a really good discharge from her pussy. Dianne got plenty onto her hand and spread the sticky mucous on Mumbles' nose and face when she handed him a banana.

The effect was almost instant. They watched as he stood tall and called loudly, beating his chest. As he did his prick surged high and waved in the air, jerking with each heartbeat. It was definitely bigger than they had thought it would be. Robyn thought she had done a good job on it before and was now a little crestfallen that he preferred the smell of a female gorilla's pussy to her expert hands, though she had to agree with Dianne that it made sense. So Robyn went into the cage while Mumbles slowly fingered his hard prick as he inhaled through his nose past the female mucous. She put some hand lotion onto Mumbles' hands and squeezed some from the bottle onto the black hard prick. The cream had the desired effect, now that his hands slid easily over his rod, Mumbles realised the feeling of fondling his cock was quite enjoyable, and set to his task with a bit more relish than before. He recalled the feeling from a couple of years ago when he ruled a group with about ten females and screwed often during the females' heat cycles.

Still, the ejaculation of his sperm into the air came as a shock to him, and he stopped masturbating and watched the fluid squirt from his shiny black rod. All the while Robyn and Dianne were congratulating him for his great work, and Robyn wrapped her expert fingers around the throbbing knob of the black weapon and wrung another couple of pulses of milk from the horny gorilla before feeding him a whole hand of bananas along with the reinforcement of her praise of his actions.

They did this two or three times a day for a while till they had Mumbles trained to leave his hands off his prick, and to let Dianne or Robyn work on it for him. He was enjoying the experience and was starting to show interest in fondling the girls' bodies through their clothing. The strong fingers stroking at her arse and pussy through her thin shorts made Robyn's pussy juices really flow, and now she was wiping her mucous on his nose before she worked on his beautiful penis for him. Mumbles was now happy to sit or lie back for the girls to manipulate his wonderful weapon to ejaculation, except occasionally they left him unfinished just before the point of no return.

Robyn told Dianne she was aching to try and have Mumbles fuck her pussy. They had noticed that the smell of Mumbles' prick and sperm made the female go almost crazy in her cage. After all, they were dosing her with hormones and she had been aching for a prick now for days. In the wild she would have been fucked at least eight or ten times by now. The girls decided to put Tess in the cage next to Mumbles so Robyn could learn the correct poses to assume to show Mumbles she was ready for a fuck.

Seeing Mumbles had the desired effect on the female. She used a number of poses to show him her receptive cunt. He responded by beating his chest and pumping his rod full of blood, ready to insert it into the waiting cunt. The only problem was they could not reach each other properly through the dividing double wire of the cages. Mumbles was able to poke a finger into her cunt and suck off the mucous, and she could just reach him, but no way would his prick reach her pussy as she pressed it against the wire, hoping for some insertion other than his groping finger.

Mumbles started to howl, and swung around his cage with his erect prick waving in the breeze. Robyn undressed and started to call Mumbles in her cool training voice from the wide mesh of the cage front. She aped the actions of the female, who was still calling from her cage. Then Robyn bent forward and backed her pussy up to an opening in the mesh, giving a full acceptance display as the caged female had done. The rough insertion of Mumbles' scaly finger sent an erotic shudder through her body as he probed her slippery cunt. Then he sucked the finger and moaned low, grabbed the cage mesh with his hands, and started to shove his rod into the waiting white cunt pouting at him through the wire. The feel of the mighty ape's penis forcing into her receptive vagina sent shudders of delight through Robyn's body.

Robyn decided she had to have Mumbles screw her properly so she stood up, leaving his shiny lubricated cock poking out through the cage mesh. She squeezed it for him with her tiny hand while he moaned in despair at his chance of a fuck having gone.

Quickly Robyn went to the gate and entered the cage, certain that Mumbles would not hurt her. When inside she started stroking his impressive cock like she did when masturbating him, then, horny as all fuck, she displayed her open cunt to him and he responded as she imagined. Mumbles' rough hands pulling her pussy toward his raging prick excited her and the sensation of his hairy thighs slamming against her smooth white arse as he rammed his rough shaft right home on the first stroke took her breath away.

After very few strokes he held her cunt hard against his crotch and fired a torrent of gorilla sperm to flood her clutching vagina. The howl he let out had to be heard to be believed, and the cries of frustrated anguish from the female gorilla, Tess, had to be heard to be believed.

The miserable sound made Dianne feel extremely sorry for Tess. It was her and Robyn's fault Tess was so fuck happy, and they weren't letting her get any. Dianne herself wasn't getting any either. Robyn was talking to Mumbles, and obviously getting his now fully functional cock ready for another fuck or two while she was still in the cage with him.

Dianne left the camera running on its tripod, still filming Mumbles' cage, and ran to the house. She returned with a double ended rubber dildo she and Robyn had occasionally used together, each riding one end of the substantial rod to respectable orgasms. She reached into Mumbles' cage and scooped some of his gorilla semen from between Robyn's pussy lips and rubbed it onto one end of the rubber cock.

Then she removed her short pants and easily worked the other end into her slippery juice filled pussy till it stopped at the knobbly balls in the middle. The angles of the manufactured cock were set so when she straightened up the other end jutted out as if she had a real penis between her legs.

"You're a horny fucker", Robyn called to Dianne as she saw her opening the gate to the female's cage with the prick standing out from her cunt, "Watch out though, she's not been trained"

"I'm gonna fuck her, not train her", Dianne yelled back, trying to walk with the great donger swaying in front of her, "and she's so fucking horny she'll let anything into her pussy just now"

"Start Mumbles off again for her to watch while I get into her", Dianne added.

Robyn gladly obeyed her friend's request, hoping that Mumbles would now fuck her for a bit longer considering he had already cum three times in less than half an hour.

Dianne need not have worried about needing to divert Tess' attention. As soon as she entered the cage Tess came up and sniffed the cock jutting out from Dianne's pussy. Her lips curled and she screamed a loud mating cry which made Mumbles look across at her to see what was going on just as he was slipping his cock into Robyn's slippery receptive pussy.

Tess made several suggestive 'fuck me' poses for Dianne and her big dick, then turned to sniff it again when it did not slam into her waiting cunt. Tess struck a particularly wide open cunted pose, poking her mucus oozing cunt at Dianne, so Dianne slid her hand into the well greased vulva, then crouched and quickly slotted the dildo home after she realised how compliant the gorilla's pussy was.

Tess groaned in joy and surprise at the size of the rod in her pussy. She pushed back hard onto Dianne, replying to the pistoning motion Dianne was managing while crouched at Tess' cunt height. The fucking motion into Tess' pussy had a similar fucking effect on the end of the cock in Dianne's horny cunt, and this, coupled with the strangely cunt stretching crouching position she was in, had Dianne orgasming within a very short time.

As Dianne erupted so did Tess, screeching a blood curdling scream while the massive cock pounded her tightly stretched pussy. Tess looked around in a sort of surprise at Dianne fucking wantonly into her greasy cunt - she knew Dianne was a female of her species, and the sudden growing of a cock surprised her. But Tess forgot about all that as a wave of carnal delight she had never experienced before surged forcefully through her making her cunt muscles clutch powerfully at the wonderful fat cock probing her throbbing ecstatic body. Tess had been fucked before in the wild, but none of her partners had taken more than a few powerful stabs to ejaculate then pull out and piss off after another pussy to shaft. This wonderful creature who fed her and now was fucking her had taken a long time to do it and Tess had enjoyed the experience greatly.

"We'll have to work on this a bit more Di", Robyn said as they embraced outside the cages when they finished, "I'm sure we have a lot more research to do on this subject. You just can't believe the sensation of Mumbles' thick prick pumping gooey gorilla sperm into you! You'll have to try it for yourself. And do you think we could teach Tess to sixty nine with us?? That's some tongue she's got there."

"I'm sure she will be willing to try anything with me now Robyn, she never had such a good fuck before, and she loves me for it."

"Let's go inside and you can show me the trick Graham showed you with the chimp last night", the horny Robyn said as they walked hand in hand towards the house, "Then tomorrow we can continue out here".
