The birthday of my dog (Fourth part: the bisexual couple)

When my dog returned home, he came in to greet me alone.

“Thank you, master, this afternoon has been incredible,” he said approaching me. “But I need to run, my balls hurt a lot, master.”

“You still have to respond to the last test of this first day,” I said. “And what I need is for you to eat something and get ready for the gift I have prepared for you.”

My dog knew that given my ignorance of his request, there was no need to insist further. He sat at the table and explained to me how sorry he felt for not having found the key and being able to enjoy that session in the abandoned house. He told me that the rush of Popper when he was tied to the tree made him lose awareness of his body and only felt how his ass was being enjoyed by male after male with the enormous pleasure of feeling hot discharges inside him.

“I have also indulged quite a bit here watching all the cruising scenes. If you make it to the end, maybe you can choose one of those males from the house for your final gift.”

During dinner, I steered the conversation towards less sinful things to calm his lust, knowing that if he saw the couple I had prepared, he wouldn’t be able to wait before the first orgasm.

One topic he spoke to me about was how calm and how much he was enjoying the sex during this first day, knowing that all the guests were on PrEP treatment, that he knew it took an effort but it had definitely been worth it.

When we finished with the food, dessert, and coffee, I took him to a room where he could see the couple waiting for him.

“When you turn on the TV, you will see the couple waiting for you. In this session, I will be with you in the room, initially as an observer, but depending on how the night goes, we will improvise.”

“What am I going to do, master?” my dog asked intrigued.

“You are going to be the gift I have made to a friend of mine,” when he heard me talking about a friend, he realized and his face showed surprise. “Come on, turn on the TV and I’ll tell you more.”

My dog grabbed the remote and turned on the TV. Veronica appeared on it, along with her newlywed husband Jose. At their own wedding, when she was quite drunk, she confessed to me that she had always wanted to see how a guy fucked her boyfriend and she knew he also had curiosity, but she wanted to wait until they were married.

Veronica was 29 years old, about 1.70m tall, and had a very well-toned physique, and at the gym (where I knew her from) she did very good work. That night she wore a tight black dress with a deep neckline that left little to the imagination of her round breasts she had. Her husband was taller than her and also had a well-toned body. He was dark-skinned, with short hair, and a very attractive smile. Seeing that the camera was on, Veronica understood that we were already watching and began to kiss her husband while with one hand unbuttoned a button of her husband's shirt to put her hand inside.

“Veronica and Jose, they are newlyweds and are curious to have a threesome with another man. But not to please her, but him. He has never been with a man, has not sucked any cock, has not fucked an ass that was not his girlfriend's, and to say that today you will be fucking his ass if everything goes as I hope.”

“Damn, master, well, his ass is as tasty as his cock appears to be… what a delight.”

I looked at the TV and saw how Veronica already had her husband's cock in her mouth.

“Now you have to enter the room and follow the instructions she gives you. You are the gift for her husband.”

In no time, I saw my dog entering the room and standing in front of them. With his back to the camera, but I could see that he was stroking his cock to tease them. Veronica hastened her blowjob and began to swallow her husband's big cock (I hadn't seen this and was surprised) all the way down her throat. Jose collapsed on the bed; seeing another man in the room had made him nervous.

Veronica asked my dog to approach, and when he was close enough, she took his cock out of his pants and began to suck him while giving a handjob to her husband. My dog looked longingly at Jose's cock, but he knew he couldn't take any step before being asked.

“I want you both to fuck me before you cum,” Veronica said as she got up and removed her dress sensually (she wasn’t wearing underwear underneath and was completely shaved, like her husband) and she took her husband's cock into her pussy. “Come on, fuck my ass.”

My dog stood behind her and removed a small plug she had inserted in her ass to accommodate his cock. As he removed it, a well-dilated anus was revealed, ready to be fucked. At that moment, I decided to enter the room and sit in an armchair at the back where I could see everything.

When I entered the room, they were already double-penetrating her, although she was the one still leading, moving up and down to feel the thrusts of the two cocks.

“So nice to have two real cocks fucking me from behind and in front,” Veronica said panting. “Jose, do you like feeling another cock inside your wife's body?”

“Yes, dear, it feels very nice, as you say, better than with the toys we have at home,” the husband said in a deep voice, interrupted by the rhythm of the fuck.

“And you, Dog, do you like my ass like a man's?”

“I am here for whatever you wish, but if you ask me, I'll tell you that it has a very delicious ass and I'm not sure if I will be able to hold back from the pleasure it is giving me.”

“If you're going to cum, I want you to do it with my husband. Slide your cock into my pussy alongside his, and fuck us hard.”

My dog obeyed and along with Jose’s cock, they began to fuck her hard and fast. My cock was getting hard again, and I decided to undress, but not touch myself, waiting to see if I had to get into action. Veronica was moaning and shouting for them to fuck her harder until my dog couldn't hold back and announced he was going to cum.

“I’m cumming, I’m cumming,” my dog said.

“Fill my pussy with warm cum,” Veronica said.

“Here's mine, dear,” Jose said.

“God, it's so delicious to have my pussy full of cocks and cum,” Veronica said.

Veronica pushed my dog aside and quickly placed her pussy on her husband's face, who opened his mouth to receive the gift she had just been given. My dog helped her husband clean her pussy. Both men began to lick Veronica's pussy, and she showed herself as a true dominatrix.

When they finished, she said, “Dog, clean my husband's mouth and cock, leave no trace of semen.”

Veronica sat on the edge of the bed and watched as the two men kissed each other. What they were doing was not a cleaning operation, and the level of heat between the two was high. My dog moved away from Jose's mouth and let a good amount of cum fall into Jose's mouth as he swallowed it licking his lips. My dog kissed him and started going down his body, completely shaved and in good shape. He stopped to lick his nipples, which he sucked and lightly bit. Veronica's husband seemed to be enjoying this first time with a man, completely immobile on the bed and letting my dog take the lead. Veronica stepped aside to give them more space and sat on my lap. I felt how wet she was on my legs, and my cock became hard. She kissed me on the mouth and whispered in my ear, “Later you fuck me, but I want to see my husband deflowered by a man.”

I focused on watching as my dog swallowed Jose's cock whole, which should be around 23 cm long, though not particularly thick. He combined deep throats with hand jobs, showing us that excellent cock with marked veins, a dark foreskin that my dog dedicated to caressing and sucking, making Jose shudder.

I loved what I was seeing, but having that beautiful naked woman on top of me and wetting my leg didn't let me concentrate. I put my hands around her waist and started to caress her clit and vulva. Veronica appreciated this and leaned back, spreading her legs wide open, giving me full access to that wet vagina. While my dog got on all fours parallel to us, knowing he was there to give pleasure to the couple and thus provide a good view to his lover’s woman.

“Eat my ass a little, please,” my dog asked.

Jose, without saying a word, got behind my dog and parted his ass cheeks, letting out a ‘fuck’ when he saw my dog's open anus that had already taken many cocks during the day. He stuck out his tongue and started to go up and down, making my dog moan and his ass open more. He began to penetrate the entrance of the asshole with his tongue, to which my dog responded with a ‘yes, yes, fuck me, fuck me...’ Jose was enjoying eating my dog’s open ass, and my dog didn't stop panting. It was so open that when he went to insert his fingers, four went in directly.

“Honey, I'm going to fuck this ass as if it were yours,” Jose said.

“Don't think about my ass, honey, enjoy your first fuck with a man.”

When he heard these words from her wife, he slowly pushed his 23 cm cock into my dog, who held his breath as he felt those 23 centimeters go deep inside his ass. When he had all his cock inside my dog, he grabbed his butt cheeks and began fucking him, slamming his cock hard until it couldn't fit anymore. Both Jose and my dog moaned, and Veronica was cumming in my hand, trying not to make any noise that would interrupt the fuck session.

“What a delicious ass you have, how you take it, you son of a bitch,” Jose said to my dog.

“Let me ride you, man,” my dog asked him.

“Come here, da... bastard,” I think he was about to call my dog ‘dear.’ He sat in an armchair in front of us and said, “sit on my cock and enjoy it.”

My dog placed his legs on the armrests of the armchair and with his hand pushed his cock all the way into his ass. Once he was impaled, he placed his feet on Jose's knees to push himself and began to ride slowly on Jose while kissing his mouth and whispering in his ear ‘feel how my ass takes your cock and fuck me hard.’ After saying this, he started giving a strong rhythm to the fuck while he bit Jose's lips, who couldn't stop moaning. My dog moved with such fervor that it seemed like he was going to break the armchair.

“Stop, stop, I don't want to cum yet,” Jose said while grabbing my dog by the waist so he wouldn't jump as much. “I want you to deflower me; I’m so horny.”

“Now you are going to be able to fuck me,” Veronica whispered in my ear. “I want you to fuck my husband in front of me, on all fours.”

Veronica sat on my lap, inserting my cock into her ass, completely wet from her juices.

“Here, dog, lubricate my husband's ass before deflowering it. And you, dear, take a bit of this to help you open up,” she said while handing him a bottle of poppers.

Little by little, my dog started sticking his cock inside, which wasn’t small either.

“Honey, it hurts,” he begged his wife.

“Hold on a bit, like you told me at the beginning, let your ass get used to it, and you'll see how you enjoy it,” Veronica said as she began to ride on my cock.

If I raised my face, Jose was right in front of Veronica's pussy and seemed to move away from my dog to eat her, but then he moved back. The fuck was beginning to take shape.

“Fuck me carefully,” my dog said, though in the next moment he asked for more forcefully, “fuck me, show my wife how a man fucks her husband.”

Having said that, Veronica sat on my cock and started convulsing as she plunged two fingers into her pussy, unleashing squirting on my dog's chest and Jose’s back, both were soaked, but they kept fucking, this time much faster. Veronica rode until she had another orgasm that this time landed directly on her husband's face.

“I’m cumming, I’m cumming,” my dog said.

“Fill my husband’s ass,” Veronica asked.

“Yes, knock me up, knock me up, that feels so good,” Jose sighed.

When my dog pulled out, Jose turned around to clean my dog's cock of cum.

“Look how wide open my husband is, don’t you want to fuck him on his debut?”

“Only if you give me your juices this time.”

We laid Jose on the bed face up and lifted his legs to leave his ass facing towards my cock. His wife sat on his face and started moving on it, as if she was masturbating with his nose. Jose stuck his tongue out to stimulate whatever he could on her. I started fucking Jose, whose ass, although my cock was much thicker than my dog’s, the cum I had left inside served as lubricant.

Jose forgot to stick out his tongue and just moaned, asking me to fuck him harder.

“Dear, I'm as much of a slut as you are,” he said to his wife.

She couldn't take it anymore and started cumming facing me, drenching me with her juices that I tried to catch with my mouth. It was salty but delicious. At that moment, I saw Jose starting to jerk off; he was about to cum and his wife brought her mouth to his cock to receive her husband's cum. 5 loads of cum hit her face. She brought it over to her husband, who started cleaning it.

I couldn't take it anymore and pulled out, cumming on their faces. Although I had had quite a few orgasms, the amount of cum I shot was not bad at all. My dog asked me to clean his cock and help them.

After finishing, we went to the bathroom to shower where we ended up fucking again all together in a human centipede with Veronica in the first carriage, followed by my dog, her husband, and me at the end of the train. That night we hardly slept.
