Sophie stood on the mat, stretching in a perfect downward dog pose. Her long blonde hair was tied into a neat ponytail, and the pink top and short shorts hugged her athletic body just right.
Mark, her personal trainer, stood behind her, watching. His broad shoulders and strong arms showed years of training.
“Perfect,” he said, stepping closer. “But try to arch your back a little more.”
He gently touched her waist, helping her adjust her posture. Sophie felt a shiver run through her body — too close, too intimate.
“Like this?” she asked, glancing back.
“Much better,” Mark replied, his gaze lingering on her round hips.
They moved on to stretching. Sophie sat on the mat, spreading her legs into a split. Mark sat opposite her, placed his hands on her knees, and gently pressed down to deepen the stretch.
“You’re very flexible,” he said with a grin.
Sophie felt heat rise to her cheeks. She knew exactly where his eyes were wandering.
“Mark…” she said quietly. “You’re looking at me like you want more than just to train me.”
He smirked and adjusted his shorts. The outline beneath the fabric was already large and hard.
“Maybe I do,” he said plainly. “But only if you want it too.”
Sophie sighed. “I have a husband.” She hesitated, but didn’t look away.
Mark stood up, slid his shorts down, and revealed himself. He was huge — easily four times bigger than her husband.
“Oh my God…” Sophie covered her mouth with her hand, her eyes wide. “You’re… massive…”
Something inside her snapped. The desire she had tried to suppress was now impossible to ignore.
“If you don’t want this, I’ll get dressed and we’ll keep training,” Mark said, looking straight into her eyes.
Sophie swallowed hard, then slowly crawled toward him on her knees.
“I can’t stop staring…” she whispered.
She carefully wrapped her hand around him. He was hot and throbbing. She leaned down and ran her tongue along the tip.
“Mmmh…” she moaned softly.
Mark groaned, placing a hand on the back of her head. Sophie took him deeper into her mouth, moving slowly, feeling him fill her completely.
“Slurp… ahh…” she moaned, licking and pleasing him again and again.
“You’re driving me crazy,” he breathed.
After a few minutes, Mark pulled her up, turned her around, and bent her over the mat. He slid her shorts down, and Sophie felt the cool air against her already wet core.
“Are you ready?” he asked.
“Yes…” her voice trembled, but not from fear.
He stood behind her, guided himself between her soft folds, and slowly pushed in.
“Ahh!” Sophie cried out, gripping the mat.
He stretched her completely, filling her in a way she had never felt before.
“Mmm… more…” she moaned.
Mark started to move faster. The sounds of their bodies echoed through the empty gym.
“Plap… plap… plap…” the rhythm grew wilder.
Sophie reached her peak first, her body shaking as her walls tightened around him.
“Don’t stop!” she begged.
He kept going until she came again, her legs trembling.
Then Mark flipped her onto her back. Sophie spread her legs wide, inviting him in.
“Take me again,” she whispered.
He slid back inside, deep and hard. Sophie arched her back, her chest rising under the tight top.
“Ohhh… Mark…” she moaned, feeling herself on the edge again.
He moved faster, groaning loudly.
“I’m close…” he warned.
“Inside…” was all Sophie could say.
Seconds later, he thrust deep and released, filling her with his warmth.
“Aahhh…” he groaned, his whole body shuddering.
Sophie lay beneath him, breathing heavily, feeling every drop inside her.
“I shouldn’t have…” she whispered, but there was a smile on her face. “But that was the best moment of my life.”
Mark lay down beside her, brushing her cheek with his hand.
“So… same time tomorrow?” he asked with a grin.
Sophie just nodded, speechless.
