Best Man to Baby Daddy

Support Tier-exclusive

Julian Cates had been in love with his best friend Mark ever since high school. It was a long-burning ache hidden in late-night texts, shoulder touches during laughter, secret glances that lasted too long, and a permanent smile on his face when they were together. And Mark, golden-hearted, charming, and wildly oblivious, had never noticed, not even when Julian helped him propose to his long-time girlfriend, Amy. Not even when Julian helped him pick up the best suit for the wedding and personally ensured it fit him well. Not even when the signs were there.

But too many drinks the night before the wedding changed things forever. It had started with trembling hands and a kiss that should never have happened. They were in Julian’s apartment, way too close on the couch, and Mark’s lips suddenly crashed into Julian’s with a heat that made the world tilt sideways. Julian barely registered the moment their clothes fell to the ground, and Mark helped him to lie on his back. He could only think of the most handsome man on earth lying atop him, fully naked and kissing him like the world was ending.

Mark’s hands were everywhere, desperately cupping Julian’s pecs before sliding them lower to grip his hips like he was trying to memorize the shape of him. All along, Julian felt Mark’s cock hardening between them and pushing tightly against his thigh. He couldn’t help but instinctively spread his legs slightly, gasping breathlessly and overwhelmed by the touch.

“Mark… We shouldn’t,” Julian said, pretending that he wanted to stop.

“Just once,” Mark whispered. “Please. Just once. Nobody will know.”

Julian nodded. And then there was no more talking.

Mark lifted Julian’s legs in the air as his mouth still stole his breath with desperately passionate kisses. Julian’s fingers twisted in Mark’s hair, moaning loudly as Mark got him in position to enter him. Part of his mind still shouted that it was wrong, but his heart and his body longed for it more. He had seen Mark naked so many times before, but having his large cock ready to stretch him was a whole different thing.

When Mark pushed his 10-inch-long cock deep into Julian, his back arched and his toes curled in the air. The sensation was better than he could’ve ever imagined. Julian’s breathing became gasps and pants, and Mark’s arousal made him pound hard and fast right away. The moans echoed in the apartment, and the smacking sound produced when their bodies collided made everything more intense and dramatic. It was a long-time dream come true for Julian, and a secret finally unveiled for Mark.

“Fuck! I’ve thought so much about what your ass felt like,” Mark said, pounding hard like an animal in heat. “Best hole ever,” he shouted as Julian was seeing stars.

The fucking continued for what felt like an eternity, but Julian and Mark wanted more. Their bodies moved like they’d been waiting since they met. Julian wrapped his legs around Mark’s waist, clutching at his back, and Mark fucked him passionately. Julian could barely process it all, and his cock throbbed hard against his abs, leaking pre-cum like a hose. Meanwhile, Mark’s cock leaked so much into Julian’s guts that it felt like an actual cum shot.

However, when they finally came, it was a lot more intense. Mark pushed harder and faster, and Julian couldn’t hold back anymore. His cock shot thick ropes of cum all over his own torso, leaving him spent but still horny. Mark, on the other hand, continued pounding. It was frantic as his hips slammed and their mouths locked in breathless gasps. Mark’s hands gripped Julian’s hips, using them for support to accentuate the forceful thrusts. Julian cried out, trying to stay quiet, but the sensation made silence impossible.

Then, Mark finally climaxed. The cum shots hit hard and fast, making them both shake, overwhelmed by the intense wave of warm seed flooding Julian’s guts. The cum shot left Julian’s lower abdomen looking bloated, but it was a dream come true. When it was over, they held each other, breathless, and slightly ashamed. But they were deeply excited about finally sharing such a beautiful and intense moment. Julian had never felt fuller, more broken, or more loved. And Mark couldn’t help but smile while they caught their breath.

However, the next day, Mark still said, “I do.” Julian still gave the best man speech at the wedding, congratulating Amy for catching such a great man and asking Julian to protect and love his wife forever. People cheered and praised the beautiful speech, but Julian disappeared the next morning. He said it was for the best.

However, seven months later, he returned. But things were different. He stood on Mark and Amy’s front porch with a belly so massive it looked nearly impossible for one person to carry. It curved far outward and high on his abdomen, taut as a drum, so that it turned heads, caused whispers, and screamed full-term even though he was still weeks away. Each of the six babies inside kicked and rolled with ceaseless energy, making the surface of his belly shift constantly beneath his overstretched t-shirt.

Julian’s once-slender frame had become almost unrecognizable. His hips had widened enormously, forcing his gait into a swaying waddle. His thighs brushed with every step, padded with softness he hadn’t carried before. His formerly thin arms now bore the fullness of someone retaining water. His chest had grown into thick, milk-heavy mounds that pressed uncomfortably against every fabric he wore. His nipples were dark and swollen, often dampening his t-shirts with intense leaking, no matter how many pads he used.

He shifted from foot to foot on the porch, groaning softly as the weight strained his lower back and hips. Even standing upright required conscious effort. His sandals looked stretched from his swollen feet, and his ankles—if they could still be called that—blurred into the rest of his legs with no clear separation.

His face had softened slightly, and his cheeks were permanently flushed with heat and effort. His lips trembled—not only from the emotional pressure of standing at this door but also from the overwhelming strain of carrying so much. Julian wasn’t near his due date, but he looked—and felt—like he could go into labor at any moment.

Mark nearly dropped the groceries when he saw his best friend’s new shape. “Julian?”

Julian nodded, shyly smiling. “Hey. It’s been a while. So, you think I could take a seat. I can’t stay on my feet for long these days.”

Amy, equally shocked, nodded and didn’t say a word until Julian was inside and seated—as comfortably as someone carrying sextuplets could manage—on their couch. She couldn’t stop looking down at Julian’s massive belly. And Mark could barely process the sight. He had heard about some men being able to get pregnant, but he never knew Julian could be one of them. He never imagined his best friend could look so round and hot.

“So… you want to tell us what’s going on?” Amy finally said, instinctively suspicious about Julian’s visit and current condition.

Julian hesitated. Then placed his hands on his belly. “Well… as you can see… I’m pregnant. I’m seven months along with sextuplets,” he said, taking a deep breath.

“We can see that, but… there’s more, right?” Amy said, raising one eyebrow.

Julian felt his heart pounding in his chest, unaware of what to say. But his hormonal, messed-up mind could only do it one way. Straightforward. “And… they’re Mark’s.”

Mark sat like he’d been hit. “WHAT? HOW?”

“The night before the wedding,” Julian whispered. “You kissed me. And it happened. I had no idea I could get pregnant. I left because I didn’t want to make things weird between us. Then I found out I was pregnant and decided to stay away to avoid ruining your life. But then I thought you deserved to know you’re going to be a dad. I’m really sorry.”

The room fell silent as Julian rubbed his belly. Amy stood and left the room. Julian expected her not to come back. But she did, with a glass of water for him.

“You’re a coward for not saying anything,” she said, setting it down beside a speechless Mark on the couch. “You’re carrying six kids. You needed help all this time. You will need help. So I guess you could move in with us. We don’t have many options.”

Mark nodded, still unsure of what to say. Julian couldn’t help but cry. He never expected Amy to be so supportive or Mark to be so quiet. But somehow, it gave him some peace.

From that day on, things in the house changed. Amy set boundaries, and Mark tried hard to fulfill his duties with her and with a very needy Julian, who cried in the shower most mornings because even rolling out of bed took too much effort. His belly was enormous, taut, wide, and impossibly round. Every movement was a waddle. Every step needed support. His tits leaked milk almost constantly, dampening his shirts within an hour. His back ached. His ankles swelled. He groaned and rubbed at the tight stretch of skin that trembled whenever a baby kicked too hard. But what surprised him most was how much Mark cared.

Mark brought pillows, rubbed his feet, and touched his belly like it held the world. Even Amy, slowly and strangely, accepted it all. She offered snacks, helped with maternity clothes, and even when she caught Julian crying, she sat beside him in silence to hug him. It was complicated, messy, and beautiful. And the bigger Julian got, the more intimate it felt for them.

One night, Julian moaned from the couch when one of the babies kicked him hard. The motion made his tits send milk spraying from his chest. Immediately, Amy and Mark were by his side. Julian wept. And for the first time, he didn’t feel like a mistake.

Amy held his hand, and Mark whispered, “We got you. Calm down.”

Later that night, after Amy quietly closed the bedroom door behind her, she left Julian and Mark alone in the dim guestroom. “He needs this,” she said to Mark before she walked away. “But be gentle with him, big guy.” Her acceptance was slightly reluctant, but real.

Julian lay back on the bed, naked as his massive belly rose high and his tits leaked. Mark sat beside him, gently moving his hand over the side of the belly, feeling the kicks and the constant motion. And Julian gasped, overwhelmed by how close and tender Mark was.

“What are you doing?” Julian asked, confused but loving Mark’s touch.

“Your hormones,” Mark said. “We know they’re intense.”

Julian nodded slowly. “I’ve wanted you for months. I didn’t know how to come and say it,” he said, feeling an intense heat spreading through his core.

Mark smiled and leaned down to kiss Julian’s collarbone, and began to trace his lips lower. Julian let out a moan as Mark’s mouth closed over one swollen nipple. The moment his tongue flicked across it, milk spurted out. Mark groaned as he tasted it, surprised but not deterred. Julian arched his back, pushing his belly high like an immense mountain.

“Mark, they’re so full, I can’t—I can’t stop leaking,” Julian moaned.

“Let them. I think it’s beautiful,” Mark whispered.

He latched on, and the milk exploded from Julian’s chest. It soaked them both instantly, pouring in hot streams, splashing against Mark’s chin and neck, and pooling beneath Julian on the mattress. Julian gasped, clutching Mark’s shoulders as the relief and arousal mixed into a dizzying, desperate heat.

Mark’s hands traveled down, caressing the curves of Julian’s hips, massaging the soreness from his thighs. Every motion was slow but intense. He eased Julian back, kissing over his swollen belly, whispering soft things against the trembling skin. Their bodies moved together, careful of every angle and curve, of every sensation.

Mark worshipped every inch of Julian’s plump body. Then, with the enormous belly cradled between them, Mark got between Julian’s legs, gently lifting them and pushing forward to slide his cock into the eager hole. Julian moaned as Mark thrust with slow intensity, careful not to disturb the nest of pillows supporting Julian’s lower back. Each movement sent waves of pleasure through them. And Julian cried out with every deep stroke.

Julian’s breath came in ragged moans as milk still spurted in erratic streams from his tits, slicking both their bodies. Mark gripped Julian’s hips, sinking his fingers into the plush weight as he drove harder. Their rhythm intensified, pushing Julian closer and closer to the edge. And then, with a strangled groan, Mark came.

The sensation surged into Julian, and in that instant, his entire body tensed. His belly visibly inflated with a sudden shift—a few inches in all directions—but enough to leave them both stunned. Julian let out a long, broken moan, moving his hands to his sides as the taut skin stretched tighter, and the babies inside shifted in protest.

The pressure was overwhelming. Julian’s nipples sprang with renewed force, coating both men in warm, white streams. Milk pooled around them, soaking into the mattress beneath. Julian trembled beneath Mark, every nerve alight, and the sensation of fullness bordered on unbearable. Julian only managed a whimper. But in his eyes, there was nothing but stunned, unfiltered adoration.

Mark whispered Julian’s name again and again, pressing his forehead against the pregnant man’s. Julian couldn’t help but cry, overwhelmed, while Mark kissed his tears away.

“You owe me something, Julian,” Mark whispered into Julian’s ear, with his cock still inside the pregnant man.

“Wha—what is it?” Julian responded. “You can ask me anything.”

“I missed seven months of this pregnancy,” Mark responded, leaning in to kiss Julian and softly bite his lower lip. “You’d better be ready for a second batch after these ones are out. Because I wanna enjoy the whole process next time,” Mark said, bucking his hips and making Julian moan and nod. “Now, let’s focus on round two. We have all night for ourselves, Daddy.”
