Helping a Team Member Stretch

The locker room was quiet except for the occasional drip of water from the showers. Alex and Mark had stayed behind after practice, the echoes of their cleats on the concrete floor the only sound besides their conversation. They'd been teammates on the recreational softball team for three years now, their friendship forged through late-night innings and post-game beers at O'Malley's Pub.
"So what's got you so down, man?" Alex asked, leaning against his locker while stuffing his sweaty uniform into his gym bag. "You've been moping around all practice."
Mark sighed, running a hand through his damp hair. "It's... kind of embarrassing."
Alex raised an eyebrow. "We've seen each other at our worst, man. After that tournament in the rain last summer, I don't think there's anything that could embarrass me."
Mark hesitated, then finally blurted it out. "Sarah wants to peg me."
Alex's eyes widened slightly before a grin spread across his face. "Really? Nice!"
"Not nice," Mark groaned. "She bought this... thing. And I don't think I can take it. She said she'd give me a week to prepare, but I'm terrified I'll embarrass myself."
"Wait, how did this even come about?"
"We were talking about anal," Mark explained, "and I said I wanted to try it with her. She said, 'Well, if you're gonna do that to me, I'm gonna do it to you as well.' And I agreed before I really thought it through."
Alex chuckled. "Classic Mark. So what's your plan? Just hope for the best?"
"I've got a toy," Mark admitted, his cheeks flushing. "But it's not going great. I'm just... tight back there, you know?"
"So are you practicing?" Alex asked, his tone shifting slightly.
"Yeah, but it's not enough," Mark confessed. "I need more time to loosen up, but I only have a week."
Alex stepped closer, lowering his voice. "Well, I can help with that."
Mark looked confused. "How do you mean?"
"I'll fuck you," Alex said simply. "I'll get you used to taking a cock."
Mark's jaw dropped. "But I'm not gay."
"Neither am I," Alex replied calmly. "You need to get your hole stretched out. I can do that for you. I'm just helping you out, man. It's only gay if I start catching feelings."
Mark was silent for a long moment, considering. The showers were still running, steam beginning to fill the room. Finally, he nodded slowly. "Okay. But we wait until everyone's gone."
They finished packing their bags and waited until the parking lot was empty. Then they headed to the showers, the sound of their bare feet on wet tiles echoing in the empty space. Alex turned on the hot water, steam billowing around them as they stepped under the spray.
"Ready?" Alex asked, his hand already stroking himself to hardness.
Mark nodded, turning to face the wall, bracing his hands against the tiles. "Just... go slow."
Alex positioned himself behind Mark, pressing the head of his cock against Mark's tight entrance. "Relax," he murmured, pushing forward slowly. "I've got you."
Mark gasped as Alex entered him, the stretch more intense than any toy he'd tried. But Alex was patient, giving him time to adjust before moving deeper. Soon, a rhythm developed, Mark's initial discomfort giving way to something else entirely.
Neither of them noticed when the locker room door creaked open, nor did they hear the footsteps of the shortstop and center fielder who had returned for their forgotten gear. They watched from the shadows, exchanging glances before stepping forward.

"Looks like you could use some help with that training," the shortstop said with a grin.
Alex and Mark both froze, turning to see their teammates watching them.
"Don't stop on our account," the center fielder added. "In fact, we might be able to help you out even more."
Mark looked at Alex, who just shrugged with a small smile. "The more practice, the better, right?"
Before Mark could respond, the shortstop was already undoing his pants, revealing his own growing erection. "I've always wanted to try this," he admitted.
The center fielder stepped closer to Mark, running a hand down his back. "Don't worry, we'll be gentle. At first."
Mark found himself sandwiched between three of his teammates, the initial shock giving way to an unexpected arousal. As the shortstop positioned himself behind Mark while Alex moved to face him, Mark realized this was going to be much more than just practice for his wife's pegging session...
The center fielder knelt in front of Mark, taking Mark's now-hard cock into his mouth as the shortstop slowly entered him from behind. Mark gasped at the dual sensations, overwhelmed but unwilling to stop. Alex watched for a moment before joining in, positioning himself so Mark could take him in his mouth while being filled from both ends.
The steam from the showers filled the room, mingling with the sounds of their increasingly frantic encounter. Mark had never felt so exposed, so vulnerable, and yet so completely consumed by pleasure. His initial worries about his wife's strap-on seemed distant now as he experienced the real thing, multiple times over.
As the shortstop thrust deeper, Mark felt himself opening in ways he never had before. The pain had transformed into an intense pleasure that made his toes curl against the wet tiles. The center fielder's mouth worked him expertly while Alex guided his movements, encouraging him to take more.
"You're doing great, man," Alex murmured, his hands tangled in Mark's hair. "Sarah's going to be so impressed."
Mark could only moan in response, lost in the sensations overwhelming him. The three teammates worked in a rhythm that had been building for years without either of them realizing it—late-night glances in the locker room, lingering touches on the field, unspoken desires that were finally being unleashed.
The shortstop gripped Mark's hips tighter, his thrusts becoming more urgent. "I'm close," he grunted.
The center fielder increased his pace, matching the shortstop's rhythm. Mark felt himself approaching the edge, his body trembling with anticipation. Just as he thought he couldn't take any more, Alex whispered, "Let go, man. We've got you."
Mark's orgasm hit him like a tidal wave, his body convulsing as he spilled into the center fielder's mouth. The shortstop followed moments later, filling Mark with his release. Alex wasn't far behind, his own climax adding to the intensity of the moment.
They collapsed in a heap of limbs and satisfied sighs, the water still cascading over them. For a moment, nobody spoke, the only sound the rush of water and their heavy breathing.
"Well," the center fielder finally said, wiping his mouth. "That was unexpected."
The shortstop laughed, slowly withdrawing from Mark. "Good unexpected, I hope."
Mark nodded weakly, still trying to catch his breath. "Definitely good unexpected."
Alex helped Mark to his feet, steadying him as his legs trembled. "So how do you feel? Ready for Sarah's strap-on now?"
Mark considered for a moment, then grinned. "I think I might need a few more practice sessions first."
His three teammates exchanged glances, identical grins spreading across their faces. "I think that can be arranged," the shortstop said, already reaching for Mark again...
