 Chapter 12 Everyone was tired after Marcie left.  After getting dressed,
the family ate a simple meal of leftovers, then Sam and Joan sat at the
kitchen table doing their homework while Caroline read a book and kept them
company.  When their homework was finished, they all moved into the living
room, where the fire was still burning.  They cuddled together on the sofa,
talking quietly and drinking herbal tea until bedtime.

   Without discussion all three of them returned to Caroline's room and
undressed for bed.  Sleeping nude together now seemed normal rather than
strange.  Sam lay between his mother and sister, sleepily nuzzling their
cheeks and necks.  After a bit, Joan drew his face to her breast while
Caroline scooted down to suck his cock.  Sam came after a few minutes of
this, and the three of them drifted off to sleep.

   They woke in the morning early again.  Joan mounted Sam and rode him to
a pleasant climax.  Then after resting a few minutes, he slid behind
Caroline and fucked her ass, as he had Joan's the day before.  They all
showered and had breakfast before Joan and Sam had to leave for school.

   Sam was less distracted than he had been the day before.  He was already
more comfortable with his new lifestyle, no longer questioning how or why
but just accepting the change in his relationship with his mother and
sister.  He chatted and joked with Gina and Cameron between classes.

   "Do you still want me to help you with algebra, tonight?" Gina asked
him.

   "Sure," he said promptly.  "Test tomorrow."

   "Yeah," Gina said.  "OK.  I'll be there after dinner."

   She seemed a little ill at ease, and Sam wondered why.  Cameron noticed
it as well.

   "What's the matter?" he asked jokingly.  "Planning to 'help' Sam with
something else instead?"

   "What's that supposed to mean?" Gina flared angrily.

   Cameron hastily backed off.  "Nothing!  It was just a joke."

   "Well, it wasn't funny," Gina snapped.  "Jeez, you guys...all you ever
think about..." She stalked off, muttering to herself.

   "What was that all about?" Cameron asked Sam.

   "Beats me," Sam said.  "See you at lunch."

   As he walked off, Sam wondered if the strange influence he now seemed to
have was affecting Gina.  It had affected many other girls, like Katarina
Miller.  Maybe Gina had been thinking about him in that way, and Cameron's
joke had hit a nerve.  It might explain her reaction.  Sam wondered about
his own feelings towards Gina.  She was his best friend; in truth, he had
had a crush on her for a long time, which he had never admitted to anyone.
How did he feel about her now?

   Sam was reminded again of Katarina Miller when he entered his next class
and saw her there, sitting in the front with her perfect profile towards
him as she talked to the girl next to her.  As if sensing his regard,
Katarina turned and met Sam's eyes; she gave him a friendly wave, then
returned to her conversation.

   The bell rang and class began.  While taking notes, Sam thought about
Katarina.  The first two women he'd slept with, Jenny and Laura, had done
so with no prompting from him; with his mother and sister, it had been a
more progressive thing.  With Marcie, he had more or less set out to seduce
her, but she'd seemed willing before he even tried.  Would a woman have sex
with him just because he asked her to?  He'd hardly talked with Katarina at
all, and they hadn't hung out together.  Normally, he was sure, she would
never dream of sleeping with him.  It would be a real test of how far his
influence extended.

   After class, Sam arranged to fall in with Katarina as they left the
classroom.  She turned and smiled at him.

   "Hi, Sam," she said brightly, "how are you feeling?"

   "Pretty good," he answered.  "Listen...did you mean what you said the
other day?  About helping me?"

   "Sure!" Katarina said.  "Why, do you need something?"

   "Well...what do you have next period?  Is it something you could skip?"

   "Just home ec.  I can miss it."

   "Great!" Sam said.  "Then...could you meet me behind the school after
classes start?"

   "I'll be there," Katarina promised.

   Sam dropped off his books in his locker and slipped out behind the
school.  There was a little grassy area hidden by some trees, where
students sometimes hung out; it was screened from the school by bushes so
no one could see them.  The only worry was that someone else might be
there, but when he arrived it was deserted.

   Katarina showed up a couple of minutes later.  "Sorry to take so long; I
had to ditch a couple of my friends who wanted to walk to class with me. 
So, what do you need?"

   Sam smiled, drinking in the sight of her.  She was wearing a white
cotton blouse and a brief black skirt, with white thigh-high stockings and
glossy black shoes.  Her blonde hair was bound back by a red ribbon, and
she had a matching red choker around her neck, the only spots of color in
her outfit.  Very subtle makeup emphasized her lips and cheeks and made her
bright blue eyes stand out alluringly.  Katarina was beautiful, and knew
it; but Sam didn't mind her vanity, since it gave him such a treat to look
at.

   "This is what I need," Sam said, and kissed her.

   She didn't respond at first, seeming a little startled by his boldness;
but after a moment she relaxed and kissed him back.  It felt very pleasant.
He put his hands on her waist and pulled her against him, feeling her soft
breasts against his chest.  She put her arms around his neck, and they
stood kissing together for several minutes.

   Sam moved his hands to Katarina's breasts, feeling them lightly through
her blouse.  Katarina let him touch her, continuing to kiss him, but
otherwise gave little reaction.  After a bit, she pulled back.

   "Here," she said, smiling slightly.  She began unbuttoning her blouse in
a businesslike fashion, carefully folding it and setting it aside.  She
wore a lacy white bra.  That was the next to go, revealing beautifully
shaped, medium-sized breasts with small but taut nipples.  Their dark brown
color stood out against her pale skin.  She kicked off her shoes, then
unzipped her skirt, setting it on the pile of her other clothes; then she
carefully rolled the stockings down her legs and removed her panties.

   "You should get undressed, too," she said, lying down on her back and
spreading her legs.  "Then you can fuck me."

   Sam had been watching her undress; he quickly removed his own clothing
and settled on the grass beside her.  Katarina certainly didn't seem to
expect much in the way of preliminaries; she just waited expectantly for
him to begin.

   Well, if she wanted to go straight to it, that was fine with Sam.  He
moved between her legs, and started to lower himself.  Katarina subtly
stiffened underneath him and he paused.

   "Are you all right?" he asked.

   "Yes, I'm fine," Katarina said, sounding surprised.  "Go on."

   Sam started to lower himself again; again he sensed a sudden tension,
and paused.

   "Do you think I'm going to hurt you?  Are you a virgin?"

   "No, I'm not," she said.  "I've had sex lots of times."

   Sam reflected briefly how one girl could have sex lots of times and
still be the school princess, while another was branded a slut.  Not that
it mattered to him.  He lowered himself again and gently eased the head of
his cock into her.  She definitely felt stiff against him, but her cunt was
moist and ready.  He pushed in a little further and withdrew; then again,
and again, small strokes, gradually getting deeper.  He kissed her and she
responded to that, relaxing a little; he nibbled down the line of her jaw
to nuzzle at her throat, then twisted a little to give one brown nipple a
quick lick.  Katarina gave a small start at that, and relaxed further.  Sam
sensed her body starting to react to his lovemaking, becoming more open,
more responsive.  Her expression looked puzzled, almost worried.

   "I, um, I feel kind of weird," Katarina said hesitantly.

   "Do you feel bad?" Sam asked without pausing.

   "I, no, not bad...just weird.  Kind of, um, ticklish or something." She
stirred a little under him.  "Um...maybe we should stop?"

   Sam didn't stop.  He thought he understood what was going on now.  "Why?
Doesn't it feel good?"

   "Uh...well, yeah, I guess so, kind of." Katarina moved again,
restlessly. Unconsciously her hips had started rocking in rhythm with his
own.  Sam felt her internal muscles beginning to contract around his shaft.
"But it feels strange...I feel strange...kind of, all fluttery." She tossed
her head, shaking her hair out of her eyes, and licked her lips.  Her
breathing was rapid.  "This...I don't feel right."

   "Sure you do," Sam told her.  "This is sex.  It's what you're supposed
to feel."

   "No," Katarina said, sounding uncertain.  "It's...I've had sex, and it's
not like this, it's..."

   "Well, it should be," Sam said.  He was pumping in and out of her pussy
like a piston and her body moved without her conscious control.  She was
very close to coming; he could tell, if she could not, and he maintained a
steady pace, pushing her towards the brink.

   "No, no, this is...something weird is happening to me...I feel...oh,
God, oh God, oh God!" Katarina yelled as she came.  Sam wondered if anyone
in the school could hear them; it would be kind of embarrassing if they
were discovered fucking on school grounds.  His instincts told him that it
would be easy to bring Katarina to a second climax; her body was still
aroused to a fever pitch.  He slowed his movements, then began gradually
speeding up again, aiming to make her come at the same time he did.

   "What...was...that...?" Katarina gasped.  Her well-toned body was
undulating against him, its reactions unaffected by her mental confusion.

   "That was an orgasm," Sam said with a grin.  "And you're about to have
another one." He twisted down and took her nipple in his mouth again,
working it with his lips and tongue in the same rhythm as his prick
pounding into her.

   "No, I...I can't...oh, fuck, oh, God, Jesus, oh!" Katarina's second
orgasm was less loud, but just as intense.  As her muscles contracted, Sam
came inside her, spraying her pussy with his seed.  The two of them clung
together, panting and moaning.

   At length, their passions sated, Sam withdrew from Katarina and sat up.
She still lay bonelessly, looking up at the sky.

   "I...I've never felt like that before," she said at length, as Sam began
getting dressed.

   "So I gathered.  Never?  Not even when masturbating?"

   Katarina blushed.  "I don't masturbate.  That is...I tried to, one time,
but it didn't work; it just felt all weird, and then it started to hurt."

   "Didn't any of your boyfriends get you off?"

   "I guess not." Katarina sat up, her pert breasts swaying, and looked up
at him intensely.  "I thought I knew what sex was like.  I was completely
wrong.  It's incredible." She shook her head.  "I thought I was doing you a
favor, but you did me a much bigger one."

   "Glad to help," Sam said.

   Katarina came into his arms kissing him, pressing her body against his.
Now that she knew how good sex could feel, she suddenly seemed to want to
make up for all the foreplay she had skipped.  Sam felt himself getting
hard again.  She was far from the chaste vision she had looked at first,
her tongue dancing against his, her tits grinding against him, her hands
roaming his body.

   "Please," she breathed, coming up for air briefly, "is there anything
else I can do for you?"

   "Sure," Sam said.  He nodded down towards his cock, rubbing up against
her belly.  "Why don't you suck me off?"

   Katarina looked suddenly uncertain.  Maybe that's the difference between
the princess and the slut, Sam thought; the slut gives head, and the
princess doesn't.  But she only hesitated a moment.  Dropping to her knees,
Katarina put her hands on Sam's hips for balance and leaned forward.

   "Just lick it a bit, at first," Sam advised.  "Yeah, that's good. 
Little kisses too.  Yeah.  Now, give it a suck -- gently.  Good.  Now lick
some more...oh, yeah, baby, that's great..."

   He continued to instruct her as she grew bolder, taking his cock further
into her mouth and sucking harder.  One of her hands left his hip to
encircle his shaft below her lips, and she started pumping him.  At his
suggestion she began using her tongue as well as her lips.  Either I'm a
really good teacher, Sam thought, closing his eyes to savor the feeling, or
she is a natural cocksucker...or maybe both...oh, yeah...

   "I'm going to come," he told her.  Katarina paused for an instant, then
determinedly continued.  It only took a few seconds before Sam came,
blowing his load into her mouth.  Katarina gave a little groan, and he
realized she had actually come again, just from the excitement of sucking
him.

   She swallowed and drew back, breathing deeply.  Her eyes were a little
wide, but she was smiling.

   "Wow," she said softly.  "I've never...I didn't realize how much fun
that was.  Did you like it?" she asked, almost naively, looking up at him.

   "Hell, yes!" Sam laughed.  "It was fantastic." He drew her up to her
feet again and kissed her.  "You should get dressed.  The period will be
over soon."

   Katarina laughed, but turned and started to dress.  "Like I care.  I'm
still walking on air." She sighed.  "It feels right to be naked with you.
Like clothes are a barrier."

   "Fair enough," Sam said with a smile, "but you probably don't want to be
naked with the rest of the school."

   "No," Katarina agreed.  They finished dressing.  Katarina put her arms
around Sam's neck and kissed him with real passion.  "I'll go back first.
Thank you, Sam.  Thank you so much." Her makeup was smudged, and her hair
was disordered, and her clothes, despite the care with which she had folded
them, looked a bit rumpled.  But Sam thought she looked even sexier now
than she had before.

   "Thank you," Sam said.  He took her arm and gave it a squeeze.  "It was
a lot of fun for me too." They exchanged another quick kiss, then she left
him, not looking back, but hips swaying enticingly the whole way.
