Tim can't hold it in

Lila's eyes searched his, looking for a reaction. Her own heart was racing, and she couldn't help but wonder what had come over her: she let a boy, a younger, shrimp-dick boy, touch her butt. She even guided his hands! She had always preferred boys with more to show off, but here she was, in the school bathroom, playing with a boy who barely had anything to show, and who could grope her ass like he please if he only wanted. She chided herself for her own curiosity, but she couldn't deny the power she felt in that moment.

Tim's hand remained frozen on her ass, unsure of what to do next. His eyes darted up meeting hers, searching for a clue as to what she wanted from him. Her fingers slid up and down against the bulge in his pants, her whole hand was too big, so she was using just her thumb, pointer and middle finger. Before he could react, Tim felt a sudden, overwhelming pressure building in his groin. He instinctively squeezed her butt-cheek.

"Lila" he croaked, his voice strained with a mix of fear and arousal.

Her fingers continued to toy with him, her thumb lightly stroking the shaft of his erection through the fabric of his pants. She understood what was going to happen.

"It's okay" she whispered, her breath warm on his forehead. "It's just us here"

The sensation was too much for Tim. With a strangled gasp, he felt his body jerk as he climaxed, a few tiny spurts of semen staining the inside of his underwear. The embarrassment washed over him in a cold wave, and he wanted nothing more than to sink through the floor.

"Looks like little Timmy enjoyed himself" Lila giggled as Tim moaned in pleasure

Timmy's face was a picture of embarrassment as he realized what had just happened. He yanked his hand away from Lila's butt his eyes wide with horror.

"I'm sorry" he choked out, his voice thick with embarrassment.

Lila's smile didn't falter, but her eyes held a glint of something... triumph, joy, amusement perhaps. She leaned in closer, squeezing Tim against her, her hand still cupping his tiny erection.

"It's okay, Timmy" she said, her voice soft. "It was just a little quick" her voice dripping with a gentle mockery that sent a shiver down Timmy's spine. Timmy's cheeks burned with a mix of humiliation and a strange, unexpected pleasure. He had never felt so small before. He didn't know how to process the emotions that were coursing through him, but he knew today he had the worst and the best experience of his life. Without thinking, he threw his arms around Lila again, burying his face in her breasts, his body shaking.

Lila was momentarily surprised, but then she felt his tiny erection fading, still trapped in his pants. Despite his condition, she couldn't help but feel a strange sense of intimacy.

"It's okay" she murmured, her voice soothing. "You don't have to be embarrassed with me."

Timmy clung to her, his glasses fogging with the heat of his breath. He had never felt so humiliated and comforted in his life. Her gentle touch on his crotch was a strange mix of reassurance and torment. He knew she could have just played with him, but the intimacy of the moment was undeniable.
