It was my birthday, a day I celebrate more for my wife than for myself. I've never liked large gatherings and I didn't usually celebrate this day. In my family, birthday celebrations were rare due to our religious beliefs, though I don't share those beliefs. However, parties have always made me uncomfortable.

Haley, my wife, let me describe her so you get an idea: the most beautiful short blonde in the world, an hourglass figure with perfect breasts, not too big nor too small, and a firm, round butt. Haley had organized a small celebration at home. She knew I didn't like large gatherings, so she only invited our closest friends. Among them was Caroline, her best friend since college. A redhead slightly shorter than my wife, who was one meter fifty-six centimeters tall. Caroline was about one meter fifty-three. Caroline was pretty, as much or more than my wife, with a slender body. I remember one occasion when Haley and Caroline asked me who had the bigger breasts. I could barely tell, though if you asked me about the butt, I wouldn't hesitate to say Caroline's was bigger. Caroline and I have always gotten along well, but our relationship never went beyond cordial friendship. The little I knew about her was that she had bad luck with men and that she and my wife kissed years ago, before we met, when they were drunk at a college party. My wife always said her friend told her she was lucky to find a man like me. Despite this, I was never interested in Caroline, not because she wasn't pretty, but because I love my wife and would never do that to her.

During the party, both of them had given me a gift, so I didn't suspect what they were planning. Haley, with an enigmatic smile, whispered in my ear that she had another gift for me later. As the night progressed, Caroline mentioned she wasn't feeling well. Haley, concerned, told her she could lie down in our bed to rest; I assumed the guest room was occupied. Over time, the guests began to leave one by one. The house gradually became silent, and the atmosphere turned more intimate. Finally, after saying goodbye to the last guest, Haley took my hand and looked into my eyes with her beautiful blue eyes.

"Go to our room," she said in a soft but firm voice.

Confused but intrigued, I climbed the stairs and headed to our bedroom. I had forgotten Caroline was still in our room. When I opened the door, I found Caroline resting on the bed, but she wasn't asleep; she was awake and dressed in provocative black lingerie, looking at me with a mix of nervousness and anticipation. The room was lit by the soft light of the bedside lamp Caroline had turned on, creating a warm and cozy atmosphere. I didn't know how to react. Before I could say anything, Haley appeared behind me and gently closed the door. She approached me, and with a smile, whispered:

"This is your other gift."

For a moment, I thought it was a joke or a stupid loyalty test or something, but Haley began to undress, revealing lingerie as beautiful as her friend's. The reality of the situation started to settle in my mind. I remembered telling Haley that my fantasy was to have an FMF threesome; she and I are very open about kinky topics, in fact, we have a BDSM dynamic, she was my submissive and I her Dom. I hesitated for a moment, wondering if this was a good idea. I feared this could damage our happy marriage. Caroline turned over in bed, lying on her stomach and moving her butt provocatively, giving me a mischievous look with some blush on her face. I tried to resist, but my wife took my hand and began to guide me towards the bed. Still in shock, my wife approached Caroline and began to gently lower her panties with a mischievous smile on her face. She tossed them aside and slowly spread her butt cheeks with her hands, revealing her pussy, already somewhat wet with anticipation.

"Master, please accept my gift," said Haley, calling me "Master." Haley and I had a BDSM dynamic, and I wondered if she had told Caroline about it, as she didn't seem to react to the word. I could feel the bulge in my pants begin to grow, and I let myself be carried away, setting aside my doubts. I began to undress quickly, possessed by the desire to fulfill my fantasy. I removed my pants and underwear, freeing my rock-hard cock. Haley looked at me and said:

"I knew you'd like my gift, Master," she said with her beautiful, soft voice.

I immersed myself in our dynamic and placed my hand on her hair, starting to caress it.

"Good girl, you always know what to give me," I said with a firm voice, but with gratitude in my words.

Finally, I decided to get on the bed and positioned myself over Caroline, aligning her body to penetrate her from behind in the prone bone position. My cock touched the lips of her pussy for the first time, rubbing the tip to make her even wetter, though her vagina already seemed quite wet. I slid inside her pussy without warning, and she moaned as she felt my cock expand the walls of her pussy. Finally, I heard Caroline speak for the first time since I entered the room, stopping when I heard what she said:

"Wow, Haley! You didn't tell me it was this big? Were you planning on keeping it all to yourself?" she said jokingly, while my wife climbed onto the bed, sitting in front of Caroline and removing her panties.

"Oh, Caroline! Don't worry, I was just testing it a bit before sharing it with you," she said, continuing with her jokes before taking Caroline's face and pressing it against her pussy. "But you'll have to do something for me if you want me to share," she added, as I began to penetrate Caroline and she licked my wife's pussy.

With each thrust into Caroline's tight and wet pussy, her face was pushed against my wife's pussy. The room filled with the moans of Caroline and my wife as I penetrated harder and faster into Caroline's pussy. At one point, Caroline screamed with pleasure against my wife's pussy when I penetrated her deeply. I remembered my wife telling me that poor Caroline had never had an orgasm from penetration, and I was going to change that. I began to hit her at the right angle, thrusting into her again and again. I could feel how her pussy was getting wetter, indicating she was close to cumming. I penetrated deeply and forcefully, and she started to cum.

"Oh, yes, my God..." she said as the walls of her pussy began to tighten around my cock. It felt so good that I couldn't help but cum inside her, pumping my loads of semen into her pussy. As I came inside her, I could see my wife cumming on her friend's face, drenching her face with her juices. Panting, she looked into our eyes.

"Come here," I ordered my wife, and she crawled over to me. I pulled my cock out of her friend's pussy, who was panting as my semen dripped from her. "Lick it," I ordered my wife, who responded "Yes, sir" and, without hesitation, buried her face between her friend's legs, starting to lick my semen from Caroline's pussy, searching for every last drop with her tongue. Surprised, Caroline didn't stop moaning as my wife's tongue began to explore inside her pussy. I went over to Caroline's face and made her clean my cock with her tongue. We all ended up exhausted, and it was too late for Caroline to go home, so we just fell asleep together in the same bed until the next day.
