FOR PRACTAL REASONS ONLY

Martha felt bloated.  It felt like her insides had solidified. She
sat on the toilet in the dormitory bathroom, staring down into her
immense cleavage.  Her nipples were hard, pressing out against her
cotton sweater.  It  was the third time today she'd tried to take a
dump.  She hadn't taken a shit since Monday, two days ago.  Even
though she felt sick with constipation, the cool air against her
spread crack turned her on.
 I'm sick, she thought.  In more ways than one.
 Sighing, she stood up, pulled up her skirt and panties, and pushed
out of the stall.  She checked herself in the bathroom mirror. She
brushed her blonde hair from her forehead, and eyed the front of her
sweater, making sure she calmed down before she went to see Rhodella,
her Resident Advisor.  If Rhodella saw she was excited, she wouldn't
help Martha a bit.  Martha made a funny face in the mirror, and
mocked Rhodella's voice, "For practical uses only, Martha." 
She took a deep breath and left the bathroom.  She walked down the
hall, past her room, to Rhodella's Number 10. 
She knocked on the door, nervous, afraid she's get upbraided again
for being frivolous.  The door opened and her RA stared down at her
disapprovingly.  Rhodella was a beautiful black girl, 21, six inches
taller than  Martha.  For a moment, Martha felt superior to Rhodella
because of how much more buxom she was.  But she glanced at
Rhodella's long tapered legs and rounded thighs.  Rhodella pursed her
thick lips.
 "What do you want?" she asked.
 "You have to help me today, Rhodella," Martha said
defiantly.  "I'm still constipated."
 Rhodella eyed her critically for a moment and her face softened.
She touched Martha's cheek.  "You do look pale. Alright, come
in."  Rhodella swung the door open and Martha stepped in the
dormroom.  It was the same size as Martha's, tiny, but the RA didn't
have to share it with a roommate.  Rhodella turned around and walked
to her desk.  The chair was pushed under it.
 Martha found herself, as usual, humbled by Rhodella's huge butt.  It
swished back and forth beneath her skirt like half the earth.
Rhodella turned to face her.  She grabbed the handle on the top right
drawer of her desk.  Her face turned serious.  "You know,
Martha.  I'm not giving you something to play with."
 "I know, I know, for practical--"
 "Uses only," Rhodella finished.  She nodded and opened the
drawer.  Immediately Martha could hear their tiny screams.  Martha
felt her heart quicken.  She stared down greedily into the drawer.
Hundreds of 1 inch tall naked men waved their
hands and clamored please to the titan women staring down at them.
Rhodella had them partitioned from each other in groups of two.
Martha felt herself  getting moist.  She reached out for one, but
Rhodella slapped her hand away.
 "Can't I pick one?" she begged.
 "Why do you need to pick one?"
 Martha was silent.
 Rhodella carefully pulled one out, and Martha was silently
exhilirated by the random choice. 
He was darkly tanned, but Martha couldn't make out any of his tiny
features.  He struggled between Rhodella's slender thumb and
forefinger.  Rhodella held him to her eyes, then dropped him into
Martha's awaiting palm.  The tiny man fell on his back, staring up at
her in horror. Martha grinned.
"It's late," Rhodella said, gesturing to her computer.
"I have to finish a paper."
 "Sure.  Thanks."
 Rhodella nodded, she seemed incredibly anxious for Martha to leave.
But just as Martha began to go, Rhodella pulled the chair out from
under her desk.  Martha gasped in disbelief.  The chair was wooden,
and the central portion was raised about a quarter of an inch, with
sloping sides. On the top of that portion was glued several strips
of red silk, an inch high.  A pale, tiny white man was glued to the
silk, face up. His miniscule mouth opened in screams when Rhodella
pulled the chair out.
 Rhodella raised an eyebrow at Martha's gasp.
 "What's your problem?" Rhodella asked.
 With her free hand Martha pointed at the struggling man.
"What're you doing with him?"
 Rhodella reached behind her, pulling up the back of her pleated
skirt and tucking it up under her waistband.
 She nonchalantly stepped around the front of the chair, her bare
asscheeks towering above the tiny man. He began to scream louder,
and the red silk was slightly moving from his futile struggle.
Martha stared in envy at Rhodella's round black ass.  Rhodella paid
no attention to the inch high man glued to her chair.
 "It's very practical, Martha," Rhodella said, still
standing.  "I've had terrible diarrhea for the past couple days,
and my ass is terribly sore from wiping so much.  You wouldn't
believe how soothing it is to have this itty-bitty white-boy scream
into my ass.  It feels wonderful.  When I sit down, his whole body is
shoved right up my butthole.  Nothing feels better."
 Rhodella pointedly sniffed the air.  "It doesn't smell like ass
in here, does it?"
 "No," Martha said slowly.
 "It should.  I've been farting all day."  Rhodella pointed
at the terrified man behind her, and finally looked at him.  She
glanced at the man in Martha's hand, then winked at her.  "He
just soaks all the stink up."  She grinned wickedly at the
prisoner in her chair, and said to Martha, "Though I have to
admit,, it's hard to concentrate on my paper." 
With that, Rhodella bent her knees, then grasped each of her enormous
asscheeks in either hand and pulled them apart, revealing her deep
asscrack.  Sighing, Rhodella slowly sunk down into the chair, and
Martha stood enthralled as the tiny white man shrieked louder than
was possible for his size.  Rhodella's huge buttcheeks lowered to his
either side,  swallowing him and his screams as they smooshed against
the seat of the chair. Rhodella wiggled around a bit and giggled,
"Tickles."
 She looked around at Martha, and her deep brown eyes were
half-lidded.  "Don't yoo dare have any fun with what I gave
you."
 Martha smiled, and dropped her human suppository into her cleavage.
He squirmed deliciously against the sensitive skin of her tits.  As
she let herself out, Rhodella released a long, wet fart that lasted
several moments.
 Rhodella said, "Only when I fart, he stops screaming for
awhile."
The door shut behind Martha, but she could hear Rhodella's quick
breathing and the chair scraping against the floor as the black
bucked her ass back and forth on the chair.
