Andrew glanced at his watch as he headed for the showers. The gym was
practically deserted. He hadn't realized that he'd been so long.
Usually he worked out in the mornings but couldn't make it today.
Feeling guilty he had decided that a quick workout at night would do
his conscience some good. As he passed by the front desk on the way to
the men's locker room he waved to Natalie, the desk clerk, and Kay, the
aerobics instructor, to let them know he was still here. They were deep
in conversation and barely afforded him a glance.

Taking off his clothes in the locker room, he thought about Kay and her
tight little body. Andrew had wanted to get in her pants for some time
now, but she barely even looked at him. He imagined running his hands
over the firm muscles of her thighs and buttocks. He'd watched many
times as they flexed during her classes. Her pert breasts were a
teasing delight, with small nipples that poked through her tight little
workout tops. Frowning at a rapidly rising erection, Andrew grabbed a
towel and headed for the showers.

The water felt good coursing over his skin and he took his time. While
washing his hair, he suddenly sensed a difference in the locker room.
Opening his eyes he realized that the lights had been turned off and
the locker room was only dimly illuminated with the nighttime emergency
lights.

"Hello?" He called into the dark room. "Hello? Is anybody there?"

'Oh no', he thought. 'I think I've just been locked in.'

He stood there in the shower for a few moments trying to figure out if
he could get out without setting off alarm, or if he would have to call
someone from the front desk. Just as he'd made the decision to check
the front door first, he heard the door to the locker room open with a
soft hiss of air.

"Hello?" he called again.

"Hello," Said Natalie from directly behind him.

Andrew jumped. "Oh! I thought I'd been locked in," he said, covering
himself with his hands in front of Natalie's scrutiny.

"You have." She stated coyly, obviously enjoying the view and his
discomfort.

Her eyes studied him from head to toe and back again, sliding up his
thickly muscled calves and thighs, lean hips, flat stomach with just a
good hint of a six-pack. They glided slowly over his well-developed
chest, until her eyes came to rest on his hands, clearly wishing she
had X-ray vision.

He felt his penis stir under his hands slightly at that casual
assessment. He took the opportunity to study her form at that time.
Natalie was a tall girl, probably about 5'8 or so, her long chestnut
hair hung to her hips in a sweeping mass at all times. Her height only
made it look longer. From time to time, Andrew had wondered what it
would be like to wrap her hair around his hand and drag her to him for
a kiss on those soft pink lips. Her green eyes sparkled with amusement
as she realized the line of his thoughts.

"Is there something I can do for you?" She taunted, staring pointedly at
his groin, which he was now having trouble keeping covered; his arousal
had grown so much.

Acting completely on impulse he reached out and acted on his fantasy. He
grabbed a handful of hair and wrapped it around and around until it was
tight to her skull, and pulled her flush against him. His mouth slashed
down against hers and he began to lick and tease her lips and tongue,
penetrating her warm mouth with enthusiasm. He slid his other hand up
into her T-shirt to cup her large breast and felt her nipple, already
hard and begging for attention. Pinching it firmly, he heard her moan
with pleasure and felt her own hands sliding down his stomach. She
cupped his balls in one hand and gave them a little squeeze while
exploring his full erection with the other. He shivered as her finger
passed over the little slit that was already oozing in anticipation.
Pulling away from him, she lifted her finger to her mouth and looked
right into his eyes as she licked the small drop of pre-cum off her
finger.

"Horny little slut, isn't she?"

Andrew eyes shot behind Natalie to find Kay standing there with her
hands casually massaging herself. Pinching her own nipples and dipping
to graze over her barely covered mound. She must have been there for a
while, because her clothes were in a heap next to her and
