Sue was clearly excited. "That was incredible, Dot," she said. "Do you really think I could learn to do it?"
"Anybody can, Sue," Emma reassured the girl. Damn, that had been pretty sexy the way Dot had got it off right in front of the two of them. Emma was getting so excited she could hardly hold still. This role she was playing, of a calm collected teacher was beginning to weigh her down. Then she had an idea.
"You say you've never had an orgasm?" she asked Sue.
"I… I guess not," the girl confessed. "One time I was out horseback riding, and I kind of felt really funny all over, but nothing happened to me like just happened to Dot."
"It's not always the same for two different people," Emma said. "You may not get it off the same way as Dot. I'll tell you what. I'll see if I can make you cum. Then you'll know what to try for yourself."
"Really?" Sue asked, big-eyed.
Emma felt triumphant. She was going to get her hands on that sweet cunt again. She read the jealousy in Dot's eyes. Sue's soft innocence was inflaming the two older sisters. Up until now, neither had thought of themselves as interested in other women. Now they were discovering the erotic possibilities of a cunt other than their own.
"Okay, just lie back," Emma said.
She draped Sue's shapely legs over the chair arms, so that the girl's sleek crotch was spread wide open. Her barely furred little cunt gaped invitingly, the pink slit clearly visible. Emma stared at the moist juicy treasures bared to her eager gaze. The soft tangle of inner labes. The tiny button of Sue's tender clit. The soft pucker of her pussy-hole.
Emma knelt in front of the younger girl. She wet a finger with saliva and started stroking it slowly up and down Sue's nakedly bared pussy-slit. A long shuddering sigh escaped the girl's innocent young lips.
"Does it feel good?" Emma asked breathlessly.
It certainly felt good to her! The soft, warm wetness of Sue's cunt was heating her up, making her wish she could feel something up inside her own hungry snatch.
Emma worked her finger up inside the opening to Sue's cunt again. It went in easier this time. The girl was stretching out a little. Emma shoved in deeper, then felt the tight membrane of Sue's hymen. The girl was definitely a virgin.
"Ooooohhhhh, Emma," Sue whimpered. "I feel so hot and shaky. Kind of like I have a fever."
"Just relax. Just lie back and enjoy," Emma said shakily. Damn, she was getting hot! She wondered if Sue knew how excited her cunt made her big sister feel.
"I don't have to do anything to cum?" Sue asked.
"No… let me do it all…"
Emma began stroking her thumb slowly up the heated length of Sue's tender pink slit. The soft inner lips curled wetly out of the way. The girl's slit was literally bubbling with juice. There was definitely nothing wrong with Sue's plumbing.
Emma's thumb reached Sue's clit. That sensitive little button wasn't so tiny any more. It had swollen, along with Sue's mounting excitement, rising up, a shiny pink knob pushing back against the pad of Emma's thumb.
Emma began to circle her thumb around Sue's clit, not touching it directly, just teasing the tender flesh around it. She noticed Sue tensing up, fighting the intensity of the feelings shooting from her clit into her body.
It worked. Sue's cunt jerked forward, her clit eager for more stroking. The girl's passion rose higher. All her earlier self-consciousness disappeared, replaced by an eagerness to feel Emma's thumb against her clit again.
When Emma had her little sister lewdly panting with desire, she pressed directly down against her clit.
"Oooooohhhhh!" Sue moaned, her lovely nude body writhing in the chair. Her belly undulated sensually, grinding her cunt up towards Emma's pleasure-giving hand. Her perfect tits had swollen to twice their normal size.
Dot, unable to stand being left out of the excitingly lewd scene taking place between Sue and Emma, came around behind the younger girl's chair. Reaching around, she cupped Sue's firm tits in her hands, squeezing, kneading gently. With a thrill she felt her little sister's virginal nipples harden and thrust up against her palms. Dot felt a twinge of jealousy. She knew she herself had nice tits, but had never seen any to match Sue's.
Sue's hands clamped around Dot's wrists. Dot thought Sue was going to pull her hands away from her two throbbing, pink-tipped mounds. But the girl surprised her, pressing Dot's hands even more lightly against the perfect fleshy spheres.
Sue was completely lost in the most intense delight she had ever known. Dot's hands on her tits felt wonderful. Emma's thumb tickling her clit was driving her up the wall. For months the girl had been having wild, half formed sexual fantasies. Her young body demanded release. And now it was getting it.
Watching Sue writhe erotically in front of her, Emma speeded up the action of her thumb. Sue's clit had swollen surprisingly large, a hard little knob, pearly towards the tip. The girl's cunt was pulsing steadily, telling Emma that Sue was close to her orgasm, if she could have one.
How she'd love to clamp her mouth down against those pink gushing pussy-lips! The thought just kind of exploded in Emma's sex-tormented mind. She glanced up and saw from the look on Dot's face that the blonde was having the same thought about Sue's tits. A sudden understanding came to the two older sisters. They both realized that such a thing might be pushing Sue a little too hard. But as for the two of them… Emma's eyes greedily drank in Dot's solid tits. Dot stared down at her big sister's fleshy cunt. A wordless agreement was reached.
But first Sue had to be taken care of. Emma concentrated on her task. Seeing that Sue was about as hot as she was going to get, Emma decided now was the time to touch her off.
The crouching brunette began rubbing her thumb rapidly back and forth against Sue's tightly swollen clit. Almost like a vibrator. Sue's eyes flew open in shock. Her whole body started to shake.
"Ooohhhhh, Emma," she choked out. "Emma… it's so good… so wonderful!"
The girl's eyes began to mist. Her face softened, her mouth pouting open. A ripple shook her stomach muscles. She didn't know what it was to cum, so she didn't realize she was cumming. But suddenly her smooth stomach muscles sucked inward. A violent spasm shook the girl's frame and she bucked powerfully upward.
"Aaaaaaaiihhh!" Sue cried out wildly.
She twisted to the side, obviously trying to escape from Emma's punishing thumb. The incredible feelings surging through her loins were almost too intense to bear.
But Emma hung in there, her thumb work slowing a little, spreading out from Sue's rock-hard clit to massage the rest of her cunt. Sue gasped and panted, flopping in the chair like a stranded fish. Her eyes were half-closed, showing flashes of the whites. Her chest rose and fell, making her tits heave up and down. Dot kept pinching the swollen nipples.
Emma finally took her thumb away from Sue's cunt. She grabbed one of Sue's hands and stuck a couple of fingers up into the girl's gushing slash.
"There… that's the way to masturbate," she hissed. "Remember how it felt and do it for yourself!"
Sue eagerly rubbed her cum-slippery fingers up and down the full length of her juicy pussy-slit for a few seconds, drawing out the last of the first orgasm she'd ever had. Then her hand fell limply down onto her quivering thigh as her strength gave out. The teen-ager lay back in the chair, fighting to regain her breath.
"Do you think you can do it yourself?" Emma asked.
"I… I don't know," Sue panted. But the look in her big eyes, no longer so innocent, said that she would try.
Dot and Emma were looking hotly at one another, their eyes raping each other's naked, sweaty bodies. "Maybe it would be better if we left you alone," Emma said thickly. "So you can kind of do your own thing. Dot and I are going into my bedroom for a while. Okay?"
