 Chapter 18 Sam woke to the delightful sensation of a warm mouth sucking his
cock.  Gina was apparently too eager for more practice with oral sex to
wait for him to wake up.  For only the second time, her technique was
impressive.  She brought Sam to orgasm after only a few minutes of licking
and sucking.

   When it was over, Sam sat up and kissed Gina on the forehead.

   "Thanks," he said.  "Nice way to wake up."

   "My pleasure," Gina said, seeming suddenly shy again.  Sam was
astonished by the two sides to her: the shy, sensible friend he'd always
known, and the wanton tigress he'd been sharing a bed with for the last two
nights.

   "What time is it?" Sam asked, yawning.

   "Pretty late," Gina said.  "We slept in.  Want some breakfast?"

   At the mention of food, Sam's stomach rumbled.  "Sounds great.  Are your
parents up yet?"

   "I don't think so," Gina said.  "It sounded like a late night for them,
too." She got up and pulled a pair of panties and a t-shirt out of a
drawer, not bothering to dress otherwise.  Sam had brought a change of
clothes in his backpack the day before, in case he was successful with
Gina's parents.  Getting dressed now, he congratulated himself on his
foresight.

   Neither Angie nor Roberto were in sight, and their bedroom door was
still closed.  Sam and Gina went down to the kitchen and helped themselves
to orange juice and some muffins from the cabinet.  While they were
nibbling on these, Angie wandered down, yawning, but looking very well
satisfied with herself.  She was wearing a nightgown made of some sheer
fabric that was almost transparent; the darkness of her nipples was clearly
visible through the cloth.

   "Oh, hi kids," she said, smiling brightly at them.  "Sleep well?"

   Gina and Sam exchanged a look.  "Yes, very," Sam said.  "Did you?"

   Angie colored a little, but if possible looked even more pleased.  "Oh,
yes," she said carelessly, "very well.  Would you like some eggs?"

   While she cooked she chatted with Sam and Gina, then sat with them at
the kitchen table to eat.  Breakfast was the only meal ever eaten so
informally in the diCosta household.  After breakfast, Gina took the dishes
to the sink and got more orange juice for Sam and herself, while Angie
lingered over her coffee.

   "Poor Roberto must be still asleep," Angie said.  "He was really worn
out last night."

   "I'll be he was," Sam said.  "At least, that was the way it sounded to
us."

   Angie blushed.  "Oh, dear.  You could hear us?"

   "The dead could hear you," Gina said.  " `Ohhh, Robertooo...' " she
imitated Angie's breathless groan from the night before.

   Angie's blush deepened still further, but she laughed.  "Well, I
shouldn't be surprised.  I don't know what came over us, but we were like
animals last night.  It was wonderful," she admitted.

   "Well, I'm sure I know what came over Mr.  diCosta," Sam said.

   Looking a little confused, Angie said "What do you mean?"

   Sam shrugged.  "I mean, you're one sexy lady, Mrs.  diCosta," he said.

   "That's sweet of you to say," Angie said.  "And call me Angie."

   "Just a fact, Angie," Sam said.  "Don't you think so, Gina?"

   Gina looked Angie over critically.  "Well, you are very pretty," she
said.  "You look good in that nightgown.  Where did it come from?  I've
never seen it before."

   "Roberto gave it to me for my last birthday," Angie explained. 
"I...well, I don't normally wear it around the house."

   "You can practically see through it," Sam observed.

   "I'd guess that was Dad's intention," Gina agreed.

   Angie was still blushing furiously, but she seemed pleased with the
direction the conversation had taken.  "Do you really think I'm sexy?"

   "Sure," Sam said.  "Here...get up."

   Puzzled, Angie obeyed.  "Put your hands over your head," Sam suggested.

   Angie did so.  Sam stooped to gather up the hem of her nightgown, then
with a smooth motion lifted it off over her head.

   "Sam!" Angie protested, vainly covering herself with her arms.

   "It's all right," Sam said reassuringly.  "You don't need to be shy with
us.  Right, Gina?"

   "Sure," Gina agreed absently, but she was looking at her stepmother's
nude body with interest.

   "Ummm...well, I guess not," Angie said, hesitantly dropping her arms.

   "See, you have a great body," Sam said.  "What do you think, Gina?"

   "Yeah, she's sexy," Gina said.  "She's got nice breasts."

   "Yeah," Sam agreed.  "Put your hands behind your head, Angie."

   Angie did so, her tits rising, dark nipples tautly erect from the cool
air and the scrutiny.  The two kids looked her over.

   "Her tits are bigger than mine," Gina commented.

   "Bigger, but yours suit you.  Short and slim as you are, you wouldn't
look right with breasts as big as Angie's."

   "Well," Gina said, stepping around Angie to look from a different angle,
"they'd definitely give me trouble on the uneven bars..."

   "They look good on her, though," Sam said.

   "Uh-huh.  She's got a nice ass, too," Gina said from behind her.

   "I need to lose weight," Angie said weakly.

   "Not as far as I can see," Sam said.  "Here, hold still."

   Sam put his hands on Angie's tits and started kneading gently.  She was
startled, but kept her position; her breathing quickened, and the blush on
her face descended over her neck and chest.

   "They're pretty firm, too," Sam said.  "Does this feel good, Angie?"

   "Y-yes," she stammered.  "Oh, God."

   "Hmm," Sam said, and leaned forward, taking a hard nipple between his
lips and sucking.  Angie closed her eyes and shuddered in pleasure.  "Yes,
that's good," Sam said, pausing after a minute.  "You want to try it,
Gina?"

   Gina was incredibly aroused by the sight of her boyfriend sucking her
stepmother's tits, but she was still a little taken aback at the question.
"Uhh...yeah, I guess so."

   "Go ahead," Sam said, stepping aside.  Gina stepped forward hesitantly,
then took Angie's breasts in her hands.  Angie sighed, and murmured "Oh,
Gina..."

   Gina began stroking them gently, fascinated as Angie reacted to each
touch.  She wondered if she looked that way when Sam was touching her.  It
was strange, but it was really hot, as well.  After a few minutes, she felt
bold enough to try sucking Angie's tits.  Her stepmother moaned aloud as
Gina flicked a tongue over her firm nipples.

   "That's nice," Gina said, drawing back.  "Would you like to try me,
Angie?" Gina lifted her t-shirt to reveal her own tits, nipples peaked with
excitement.

   With a moan Angie put her arms around Gina and took a nipple in her
mouth.  Gina sighed at the pleasure and held Angie against her.  Sam
stepped behind Angie and ran a hand over her ass, then between her legs.

   "You're really wet, Angie," he said, stroking her.  "Would you like me
to do something about that?"

   Angie moaned, half anguish, half entreaty.  Gina looked into Sam's eyes,
her own bright with excitement.

   "Do it, Sam," she whispered urgently.  "Fuck her.  I want to watch you."

   Angie made a sound that might have been protest, but Gina held her face
against her breasts and drew her down to the floor.  Sam unfastened his
trousers and drew out his cock, kneeling behind Angie.  He placed the head
of his prick against her snatch and pushed in.  Angie's moans redoubled as
she felt him inside her.  She was so wet that there was virtually no
resistance to his strokes.  Sam caressed her buttocks, then leaned forward
to clasp her breasts from behind, squeezing them in time with his thrusts.

   Gina was now too aroused to keep still.  Disengaging herself from
Angie's embrace, she removed her panties, then sat in front of the other
woman with her legs spread, leaning back on her elbows.

   "As long as your mouth is free," Gina said to Angie, "you might as well
use it for something else..."

   Angie groaned, but obediently leaned forward and licked at Gina's pussy,
provoking a sharp hiss of indrawn breath.  Quickly getting into it, the
older woman began licking her stepdaughter enthusiastically.  Meanwhile,
Sam continued to fuck her from behind, feeling like the conductor of an
orchestra bringing them all to climax simultaneously.  Gina and Angie were
both so turned on that it wouldn't take much time to bring them off.  He
sped his thrusts, moving towards his own orgasm, breath rasping in his
throat as his thighs struck repeatedly against Angie's soft ass and his
hands pulled almost roughly at her nipples.  His eyes met Gina's, and he
saw her astonished expression as she came.

   "Oh, fuck!" she said.

   Sam came then as well, spurting into Angie's moist cunt.  The stimulus
from the two youngsters was enough to bring Angie off as well.  For a long
while the three of them clung together, riding out the waves of pleasure,
moans and groans filling the air.

   When they were finally done, Sam withdrew from Angie and rose to his
feet, refastening his trousers.  He gave a hand to Gina and another to
Angie, helping them up.

   "Well, that was fun," he said.  He picked up Angie's nightgown from the
floor and handed it to her.  "Say, Angie, why don't you go upstairs and
give your husband a proper wake-up call."

   "Yeah," Angie agreed, accepting the nightgown from Sam absently.  She
seemed dazed from the pleasure she had just experienced.  "Yeah, I should
do that.  See you later." She left the kitchen, and they heard her climbing
the stairs.

   Gina had picked up her panties and was examining them critically. 
"These are soaked.  I guess I'd better get a fresh pair." She turned to Sam
and wrapped her arms around him, squeezing tightly.  "That was...wow!  I
can see that being your girlfriend is going to be even more interesting
than I thought."

   "I hope so," Sam said, kissing her.  "I certainly enjoyed it."

   "Mmmm." Gina hugged him again, then released him to rub her bare ass. 
"Next time, though, let's do it in a room with carpeting.  The floors in
here are too hard."

   "Yeah," Sam agreed.  "Maybe I should invest in some knee pads."

   Laughing, the two of the returned to the table to finish the remains of
their breakfast.
