I also joined in. "Happy birthday, Greta. I hope your desires were fulfilled to your satisfaction."

She nodded with happiness, and said, "Yes, my wonderful lovers. I couldn't have asked for more. There is only one thing left to do now. Goldie has missed all this, poor thing. Armand, why don't you bring him in and let him join us?"

Armand went out to get the dog. I asked Greta, "What do you have in mind? Aren't you sore by now?"

"Yes, but I don't want to deprive Goldie of his share of the pleasure."

"Can you handle him after all this?"

"I think so. I will need your help and guidance. I know about his knot, as you described it in your e-mail. I jerked him off a few times, and I was so amazed at the size of his knot, and his cock when he starts ejaculating. I know I don't have the energy to get locked up with him tonight, but if you could guide him into me, and show me how to handle his knot, may be I can let him lock up with me some other time."

"It's not very difficult to prevent the knot from getting into you."

"You do it then. I don't have any energy to take the doggie position for him. Here he comes. Look how excited he is already. All the noise and smell must have turned him on. Look at his cock, it's already stiff and ready to go. Come on. Goldie. Come to mummy."

Goldie jumped up on the bed, and put his front paws on her shoulder, humping his butt in her face. His red cock was already dripping with his ejaculate as he tried to fuck her face. Greta grabbed his cock, and squeezed it hard. Goldie whimpered and backed off.

"That's better," she said, "Now you behave, and I'll let you have a new treat." She spoke to the dog as if he was another human being. I looked around to see where Armand was. He was getting ready to shoot the next video.

Greta lay back on the bed, and pulled the dog on top of her. Goldie spread out on top of her tummy, and started licking her face. She kissed him, and started stroking him gently. It was clear to me that the woman and the animal loved each other deeply. The dog mellowed and almost purred as she stroked him flanks. Slowly she reached between their bodies and touched his cock which had almost receded into the sheath.

Goldie immediately started to get up, but Greta held him down. She pushed him down gently until he was lying squarely between her legs. She opened her thighs and pulled him up again. As the dog slid forward, the tip of his cock made contact the her pussy lips. Greta moaned and reached for the cock, pumping it to extract its full length from the sheath.

She looked at me. I said, "Let Goldie fuck you in this position. I will guide his cock in you. Once he is in all the way, he will know what to do."

Greta nodded and arched her hips to present a more comfortable angle to the dog. I raised the dog, and guided his fully extended cock into her passage. The dog jabbed at her opening once and missed, brushing her clitoris instead. Greta gasped with pleasure. The dog found his mark in the second attempt and let out a howl as he buried his cock into his mistress. He immediately began humping her with typical canine frenzy. I could see his cock swell rapidly, and so could Greta, as her moans increased in intensity as the dog began pounding her overworked pussy.

I reached under the dog, and found his knot. He was ramming his cock so hard that if I had not clasped my fist around it, he would have pushed the knot all the way into her. The dog began to shudder as his orgasm began. He whimpered and continued to jerk his hips rapidly, squirting copious amount of thin, colourless fluid which began dripping out of Greta's passage. I pulled the dog back and his cock slipped out of her. The dog continued to jerk his hips, spraying Greta's stomach, breasts and face with his semen. After several minutes, the dog stopped, and jumped off the bed. He sat down in a corner and began licking himself.

I watched Greta's face. She was happy that her desire to couple with the dog had finally come true. But she was unsatisfied. She needed another release. She beckoned me to her, and said, "I need to come. Please fuck me now."

I climbed into the bed, and immediately found myself being clasped in a vice like grip of her legs. Adjusting my position, I lowered myself between her legs, and guided my hard cock into her passage. Greta reached own and took hold of my cock, and thrust her hips up. The cock slipped in immediately into her well-lubricated passage.

As soon as I had buried my cock all the way into her, Greta hugged me tightly, and whispered, "Just lie on top of me like this. I want to feel your closeness for a while. Don't move."

We lay in each other's arms for several minutes, enjoying the warmth of our arousal, and the feeling of bliss that comes from a deep penetration, and embrace of two naked bodies. Greta kissed me repeatedly, and whispered, "It feels so wonderful to have you deep inside me. Please make slow love to me. Prolong it as much as you can. I love you."

"I love you also, but I think you really mean you love your husband who is broad-minded enough to let you have sex with a stranger like me."

Greta smiled happily, and looked at her husband, who was filming our union. He winked at her and gave her a broad smile of approval. I turned to look at him. He winked at me, and said, "Make love to my wife, David. She likes to be aroused all over her body."

I began kissing and licking her face, moving slowly down to her neck, and buried my face in her tantalizing cleavage. I cupped her breasts, and pressed them against my cheeks, kissing the sides in turn. Her nipples were hard like rocks, and she moaned with pleasure as soon as I took them in my mouth and began sucking them. She moved her pelvis against my buried cock, trying in increase the friction on her clitoris. I gently wiggled my hips, rotating them without pulling out. Greta gasped as my shaft rubbed against her mound.

I continued to kiss her breasts, and knead the firm flesh. I was amazed at the muscle tone of this 44 year old woman. She had kept herself in good shape. Even her cunt was tight for her age, having given birth to two children. I was thoroughly enjoying the intimate embrace of this sexy woman, who was totally consumed by her sexual desire.

Without breaking contact, I arched my back, and began kissing her stomach and belly button. Greta gasped, and said, "Please make love to me. I want to feel your cock moving inside me." she wrapped her legs around my waist, and began moving her pelvis against my thrusting cock. I started humping her in a steady rhythm, slamming my cock fully with each stroke in her slippery pussy. Greta moaned without inhibition, rolling her head from side to side as her orgasm approached. She started plunging back against me, lifting her butt off the bed, and meeting my downward stroke with an upward thrust of her pelvis.

With the amount of slippery fluid dripping from her aroused pussy, every thrust caused my cock to make a swishing sound as it entered her pulsating passage, and drew more of her juices out on the outward stroke. Armand came closer, and aimed the camera on the union of our genitals, as I increased my tempo. I was getting close to my orgasm, and could feel the churning of my balls. Greta must have felt it also, for she reached down to cup my balls and began massaging them with her fingers. I could feel my cock swelling with excitement, and finding her passage getting tighter as I continued to ram her full stroke. Suddenly, I stiffened as my cock twitched hard and exploded into her. Greta clutched her muscles, gripping my cock even tighter as she raced to her orgasm. She pulled me down on top of her, and moaned loudly as the changing angle of my penetration caused her clitoris to rub hard against my plunging shaft. Her body convulsed in rapture as the orgasm shook her to the core. I collapsed on top of her, drenching her with my semen. Our bodies were firmly locked together, and I could feel our juices dripping out of her overfilled passage.

Armand closed in on our faces, filming our deeply satiated expressions, as she kissed me, and caressed my face. I held her tightly in my arms and rolled over, pulling her on top of me. Greta began humping my still hard cock, trying to squeeze the remaining juice from my balls. Her hips undulated provocatively against my hard shaft, and Armand had a perfect view of her drenched pussy assaulting my cock as she fucked me. She screamed with another orgasm that knocked the wind out of her, and she collapsed on top of me, completely drained.

Armand put the camera away, and joined us in bed. He pulled his wife in his arms, and kissed her tenderly. Greta continued to clasp my cock in her tight passage as she turned sideways and kissed her husband.

"I love you so much, Armand. Thank you for fulfilling all my fantasies tonight."

"I love you, sweetheart, and I am really happy you enjoyed this orgy. I enjoyed it, too. We will have a great time watching this night on tape later. I think we have to thank David for participating in our dream night."

I smiled at them, and said, "Please. It was my pleasure and privilege to make love to your beautiful wife, Armand. And Greta, I will never forget this night. I never met a sexy woman who loves fucking so much. Thank you for making me a part of your fantasy. I hope I have given you the present you desired for your birthday."

Greta kissed me deeply, and said, "Yes, David. I have never enjoyed making love so much, since this is the only time I have done it with some one other than my Armand. You are very kind and skilled lover, and I hope that after this, you will find the missing excitement with your wife when you go back."

"I also hope so, Greta. Thank you both for having me," I said, and gently rolled out from under her. My cock slipped out of her tight passage, and I stood up by the bed, looking at the husband and wife.

Armand looked at his watch. It was nearly 2 a.m.

"It's rather late for you to go back to your hotel, David. Why don't you spend the night here?"

Greta rolled on her back, displaying her glorious nakedness to us. She took my hand, and said, "Yes, David. Please stay here for the night. We can take you back to the hotel in the morning."

"All right," I said, wondering where I might sleep. I was beginning to feel quite sleepy after all this physical exertion. Greta slid to the middle of the bed, and patted the space next to her. "Come on them. Get in the bed on this side. I want to sleep between you two."

Armand laughed, and said, "It will be the most delicious sandwich anyone could have. Anyone want to take a shower before retiring?"

Actually, we all needed to shower, because our bodies were quite sticky with perspiration and all the love juices we had been squirting on each other for the last four hours. We walked into the shower stall, and began cleaning each other. As Armand and I began soaping Greta, she became aroused, and started fondling her husband. He grabbed her by the waist, and she climbed on top of him, encircling his waist. Armand braced himself as she impaled herself on his already stiff cock, and leaned back to kiss me. I put my arms around her and cupped her luscious breasts. She rode her husband as we fondled and caressed her most intimate parts. I reached between her legs, and ran my fingers around Armand's cock pumping into her, caressing her cunt lips and massaging her rectum. Greta moaned loudly and stiffened, as orgasm suddenly hit her. She clutched her husband tightly, and let out a scream, grinding and rotating her hips against his buried shaft. My fingers touched Armand's balls, and I began fondling them as he jerked his hips, ramming his throbbing cock deeper into his wife. He shuddered and short his load into her. I could feel the sticky fluid dripping down on my hands as it trickled past his rod, and ran down my fingers and wrist.

Greta dropped her legs to the floor, still impaled on her husband's cock, and hugged him. they kissed deeply and fervently as the glow of their simultaneous orgasms slowly subsided. Then she turned to me and kissed me. "I would like to satisfy you also, David."

I shook my head, and said, "It's all right, Greta. I don't think I can endure another excitement now. I am a bit tender after all these orgasms."

Greta caressed my semi-hard cock, and kneeling on the floor, she put the tip in her mouth. It was quite an erotic sight, with water dripping from her head on to her face, as she slowly sucked my cock, making is hard again. She cupped my balls, and continued to suck on my shaft gently. I stood before her, watching her voluptuous mouth circling my shaft, and enjoying her oral loving. The sight was too erotic for me to contain myself. I felt the familiar churning in my balls again, something I never expected to happen in such a short time after my last orgasm. I started humping her mouth, holding her head in my hand and jerking my hips against her maddening lips. Greta braced herself, and pressed her finger between my balls and the anus. That triggered such a sharp throbbing of my cock that I gasped involuntarily, and immediately shot off a powerful jet of semen into her mouth. Greta swallowed it all, gulping and licking my spurting cock. Finally, she took it out of her mouth, and stood up.

"I couldn't leave you unsatisfied after all this love you have given me. Now we can all sleep happily in each other's arms. Let's go."

We dried ourselves, and stepped out of the bathroom. Greta pulled us both into her arms, and hugged us. "Cuddle me, my handsome lovers, and give me the warmth of your bodies. I love you both very much.

We retired to the bedroom, and stumbled on to the bed. In a few minutes, we were fast asleep. They dropped me off at my hotel around noon, and we took leave. Greta gave me one last, deep kiss, and said, "Thank you for the best birthday present, David. Please call us when you are in town again. Armand and I would like to get together with you and may be we can go somewhere for an outing."

We bid goodbye to each other. I turned and walked into the hotel. I heard the car moving out, and turned one last time to wave them. Greta blew me a kiss and a lovely smile. Armand gave me a thumbs up sign, and waved. I watched the dust kicked up by the screeching tyres until they were out of sight. It was a weekend I will never forget.
