Dinner was uneventful, which was good.  Melinda had told her
step-father that she was doing extra credit in Math to pull her
grade up.  His only comment was a grunt, a glare, and a growled
"I'll believe it when I see it!"
         Afterwards, Melinda helped her mother with the dishes, then
retired to her room to do homework.  She stripped off her shorts,
and sat at her desk clad only in her tee shirt and the bikini
panties that she had worn at school.  The crotch of her panties
were still moist from her afternoon's adventures, and she could
smell the musky scent of her sex.
         She was still horny, she realized as she sat there and tried
to study, but couldn't.  The thought of beautiful Karen licking her
pussy until she came paraded through her thoughts.  And the twins,
standing at attention.  And Karen, lapping cum out of Mr. Johnson's
cupped hand like a dog.  And the dogs.  The big red sex machine
fucking the daylights out of the tiny blonde.  Melinda was
disgusted, yet excited at the same time.  And definitely still
horny.
         Melinda leaned back in the chair and slid her hand under her
panties.  She could hear the TV blaring downstairs, so she knew
that her mom and step-dad would be occupied for a while.  Her eyes
closed and she started to gently massage her mound, and she started
to remember the afternoon's delights, moment by moment.  she could
feel the moist fabric of the panties scrape against the back of her
hand.
         She was startled out of her reverie by a coarse whisper.
         "Whatcha doin' Mel?"
         She turned quickly to the door to see her step-brother
standing there, a depraved grin spread across his face.
         Rob was two years older than she.  He was tall, and not bad
looking, with shoulder length brown hair, dark eyes, and a nice
body.  Melinda froze, her hand still in her pants.
         "Whatcha doin' Mel?" the course whisper echoed again.
         Melinda blushed furiously, but didn't speak.  What could she
say?  Rob had been attracted to her from the first, she knew. 
Almost every day he found some excuse to stop by her bedroom and
make some comment on the way she looked.  And she had to admit that
she enjoyed the attention.  
         Occasionally, she would even tease him a little, by walking
down the hall with only a towel draped around her otherwise nude
body, or bending over in front of him when she wasn't wearing a
bra, or numerous other seemingly innocent acts.  She liked the
reactions she would get from him.  Like seeing his adam's apple
jerk in his throat as he swallowed hard.  Or the blush on his face
when he knew he had been caught looking.
         "Whatcha doin, Mel?" the coarse whisper came a third time. 
He was different looking this time, Melinda thought as she stared
at him.  There was a knowing gleam in his eye as he had suddenly
realized she may not be as innocent as she acted.
         He grabbed his crotch meaningfully, cupping his balls in the
palm of his hand.  He was wearing only jockey shorts, and Melinda
noticed how big the bulge of his cock was, for the first time.  She
looked at it speculatively, and decided that he wasn't hard ---
yet.
         "Why rub yourself raw, when you could have this?" he asked
hoarsely and leered, bouncing his heavy balls in his hand
suggestively.
         Melinda couldn't help but notice the way his heavily muscled
chest flexed when he did that, and admired the way his wide
shoulders tapered to narrow hips and a muscular, round butt.
There was a circle of fleecy brown hair around each nipple of his
otherwise hairless chest.
         Rob stepped into the room after looking down the hall toward
the stairway.  Quietly he closed the door and stood there for a
moment, staring at his step-sister.  His hand remained on his
bulging crotch, but remained motionless.
         Melinda didn't move.  Her eyes were glued to her step-
brother's crotch, and without conscious thought, she licked her
lips invitingly.  Her finger moved ever so slightly again, rubbing
the clit that was concealed in the slimy fold of her slit.
         "Let's see what I could have, Rob!" Melinda said in a raspy
whisper, while rubbing herself again with a more obvious motion.
         Rob grinned openly, and pulled the elastic waistband of his
jockey's down in front to expose his cock.  He positioned it band
under his balls and let it go.  The elastic lifted his heavy cock
and balls causing the quickly hardening organ to jut out at her.
         Melinda could see it throb with every beat of his heart at it
grew heavy with blood.  It was framed with a dense growth of curly
brown hair.
         "Bring it over here!" she commanded in a husky whisper.
         By the time he crossed the few feet of carpet to her desk, his
cock was pointing proudly toward the ceiling.  She looked up to his
face and peered directly into his eyes as she enveloped the head
of his throbbing cock with her lips and sucked on it lightly.  His
eyes rolled back in his head as his eyelids slammed shut.  He let
out a loud groan.
         Melinda quickly removed her mouth from his cock and whispered
harshly, "Quiet!  You keep quiet, or we're busted!  You want them
to hear us downstairs?"
         Rob's eyes opened wide in obvious fear, and he shook his head
no.  "Sorry," he hissed.  "It just felt so good!"
         Melinda smiled at him perversely and clamped her lips around
the head of his cock again.  This time she ran her tongue around
the top of the head, and then flicked the sensitive underside of
it several times with the tip of her tongue, before engulfing about
half of it with her mouth.  Her finger continued to rub her swollen
clit as her slit became even wetter.
         Rob stifled a groan successfully as Melinda sucked and licked
at his cock.
         Then Melinda grabbed his heavy balls with one hand and
squeezed them gently.  Without warning she felt his legs stiffen
and a hot slug of his cum jetted out of the end of his cock and
slammed into the back of her throat, almost causing her to gag
before she swallowed by reflex.  Within seconds, he was pumping
load after load of hot slimy fluid into her mouth and she was
swallowing the thick fluid as quickly as she could.
         She couldn't believe it!  She had barely gotten started, and
he was cumming already!  The syrupy flow subsided, and Melinda felt
his legs relax as his orgasm receded.  She looked up at his face
as she sucked the remaining juices as they oozed out of the tiny
opening at the end of his cock.  He had a speepish grin on his
face, and was noticeably embarrassed.
         "Thanks, Mel," he murmured softly.
         "What about me?" she complained, letting his softening cock
drop from her wet lips.
         "Gimme a sec," he mumbled quietly, then reached down under her
arms and lifted her bodily from the chair.  He turned around and
set her down on her feet, then sat in the desk chair.  His jockey's
were still on and the waistband pushed his cock and balls up from
between his legs.
         Rob reached out and pulled her wet panties down to her ankles,
and Melinda dutifully stepped out of them while she pulled her tee
over her head and threw it to the bed.  He pulled her to him and
took one nipple into his mouth roughly.  It was still sore from Mr.
Johnson pinching it so tortuously that afternoon, and she gasped,
too loudly.
         Rob thought that meant she was enjoying it and went to work
with his tongue and teeth feverishly.  In spite of the pain, she
felt her nipple harden quickly at his harsh touch.  He was
squeezing the other baseball-sized breast roughly with a calloused,
muscular hand.                    Rob's cock was growing hard again quickly.  He
turned her around, grabbed her waist and pulled to down to his lap. 
His hard cock nestled in the crack between her ass cheeks.  Melinda
felt one hand reach up and grasp a breast, as the other squeezed
in between her  ass and his thigh to grab his stiff cock.  
         As she lifted herself up slightly, he positioned it and pulled
her back down.  Melinda felt the head of it try to penetrate her
asshole, which was still sore from Mr. Johnson's rape of it the
previous day.
She cried out sharply in pain, then covered her mouth quickly with
her hand.
         They both stopped and listened intently, to see if they had
been heard.  The TV continued to blare downstairs, and there was
no indication of any activity.
         Melinda reached between her legs and grabbed Rob's long cock
with one hand and positioned it properly in her wet slit, then sat
down on it, totally engulfing it in one smooth maneuver.  They both
gasped softly at the wonderful sensation, and Rob started to lift
his hips to meet her slow undulations.  They established a
satisfying rhythm quickly, as if they had been fucking each other
for year.
         "O-h-h, yes, Rob," Melinda hissed.  "Fuck me with your huge
cock.  Fill me up with it!  It feels like you're breaking me
apart!" 
         Rob let go of her tit and place both hands on her hips,
pulling her down farther on his cock.  He see-sawed her hips back
and forth rotating them slightly on his cock as she slid up and
down on him.
         Melinda felt a small shudder in him, and reached between her
legs ro rub her raging clit.  He wasn't going to do this to her
again!
         "I'm close, Mel," he advised hoarsely, and started moving his
hips savagely to thrust into her even more deeply.
         Meldinda felt a shiver track down her back and clamped her
cunt muscles down on his cock as she rubbed her clit with panic. 
She had to cum before he finished!  She had to!  
         Within moments, she was there, and great waves of orgasm
racked her, causing her cunt muscles to spasm almost painfully. 
She clamped her mouth shut and put a hand over it to muffle her
moans of ecstasy.  Sweat poured from her forehead and stung her
eyes.
         Then, Rob was shooting into her again.  Melinda could feel her
step-brother's cock stiffen and swell to even greater size before
it squirted hot liquid into her steamy cunt.  Wave after wave
pulsed into her, to be squeezed out of her dripping cunt every time
he pistoned into her.  It smeared across their thighs and her ass
until they were sliding together in the slimy stuff.
         Melinda leaned back against him, exhausted.  She heard him
chuckle softly.  "What a fuck," he mumbled into her back, and she
could feel his cock shrink quickly, now that he was spent, allowing
more of his slimy cum to trickle from her pussy.  
         Melinda stood up, and his limp cock plopped against his hard
tummy as it slipped from her hole.  She reached down between her
legs and got a couple of fingers full of their blended juices and
slipped them into her mouth to suck them clean.  She could see the
slickness of their cum covering his upper thighs.  Globs of it
peeked from the hair around his cock.
         "G'night Rob," she whispered coyly.  "I'm tired."
         Her step-brother shook his head as he stood, pulling his
jockey's back up to cover his red, wilted cock.
         "Gawd, Mel," he said, still shaking his head, and quickly, but
quietly left the room.
         Melinda pulled on a robe from her closet, and padded toward
the door.  She was going to have to take a shower to get this stuff
off of her, she thought.  As she opened the door and stepped into
the hall, her stepfather, his back to her, reached the top of the
stairway, then turned and leered at her lustily.  She felt herself
pale at his gaze, then blushed hotly. 
         He licked his full lips wetly, then turned and walked down the
stairs, leaving Melinda to slump back against the doorframe.  What
all had HE seen?
