Part Three


My evening with Gail was...well, weird. She was clumsy and seemed
about a million times more nervous than I was. I thought it was
cute, though. We messed around on her computer for a while and
then sat down to watch a movie. After a few minutes I moved
closer and put my arm around her like Cassie had showed me. Gail
seemed tense, but she didn't pull away.

I don't remember exactly how it started, but before long we were
making out. I'd just gotten her to open up and let my tongue in
when she suddenly burped right in my mouth. It wasn't even gross
really, just surprising. I started to laugh it off but Gail
covered her face with her hands and ran to her room, looking like
she wanted to die. I spent about ten minutes in the hallway
trying to get her to open the door, but she wouldn't answer me. I
finally left after saying I'd call her later.

Women.

Cassie was on the phone with one of her friends when I got home.
I tried to get her attention but she ignored me and kept talking.
I knew she'd probably just laugh, but I needed some advice about
how to convince Gail that I didn't hate her. An hour later my
sister was still on the phone. Her blabbing was starting to get
on my nerves, and feeling the need to be annoying I went over and
sat next to her, immediately putting my hand on the crotch of her
shorts. She glared and pushed my hand away, but I kept putting it
back. She gave me another shove and mouthed the words 'stop it'.
I grinned and continued grabbing at her dick, feeling it get
harder every time I touched it. Distracted by her conversation,
Cassie relented and I slid my hand into her shorts and grabbed
her cock directly. It was warm and seemed to throb stiffly as I
put my fingers around it.

She was talking about some guy at school now. I leaned in and
rubbed my face in her boobs, making a 'wakka wakka' sound like
Pac-Man eating dots. She smacked me on the head with the phone
and pushed me away, keeping her elbow out so I couldn't get too
close. My hand was still tugging her dick though. I could feel
the tip getting slick with precum as I started jacking it up and
down with a stronger grip. I was just debating whether or not to
take it out of her shorts when the front door opened and our mom
walked in. Shit. She wasn't usually home this early.

I yanked my hand out of Cassie's pants and slid further away from
her on the couch, grabbing clumsily for the remote. I turned on
the TV on just as Mom walked up and gave me a kiss on the cheek.
Out of the corner of my eye I saw Cassie shift her body to one
side to hide the bulge in her shorts. I doubted that Mom had seen
anything, but it was still a close call.

She was just swinging by to pick something up on her break. A few
minutes later she was gone again, and a few minutes after that
Cassie finally hung up the phone.

"How's your butthole?" I asked casually, still flipping channels.
She came over and punched me hard on the shoulder before grabbing
the remote away.

"That's for when I was on the phone." She sat back down and
clicked to the sports channels. "Short date," she commented,
looking at the clock. "Must've gone real well."

I told Cassie what happened. As expected, all she did was
chuckle. "Ha. She'll get over it. Just be glad she didn't throw
up on you."

"Oh?" I said, raising an eyebrow. "Speaking from experience?

She flipped me off without even looking. "Suck it, douche."

"Take it out and I will," I said, only half-joking.

She threw me a quick glance and rolled her eyes. I was a little
surprised when she reached down and started undoing her shorts.
She pulled her dick through the fly and sat there, her hand still
on the remote.

"Well?"

I hesitated for a second. I hadn't been expecting her to actually
do it. But what the heck. I slid down next to her on the couch
and put my mouth around her cock, feeling it quickly getting hard
again as I ran my tongue around the head. It tasted clean and
just a little salty. I could smell Cassie's faint perfume as I
began sucking at her penis. I'd almost forgotten how much I
actually liked doing it. So I sat there and gave my sister a
blowjob while she watched Sports Center, her body shivering and
her stiff cock pulsing every so often in my mouth as I sucked up
and down on as much of it as I could.

She acted like she was trying to ignore me at first, but after a
little while I felt her fingers brushing against the back of my
head. She played with my hair gently as I bobbed on her dick. I
took my time, licking and sucking slowly until I finally felt her
body tensing up. She groaned loudly and put her hand behind my
neck as she came, holding my head down over her cock as she
shuddered and spurted into my mouth.

"Oh *fuck*," she gasped, her body shivering. I kept sucking until
she started to go soft, feeling rather proud of myself for making
her nut so hard. She'd even cum more than usual. A plan came to
me and I kept it in my mouth as I let go of her cock and sat up.
Cassie was laying back with her eyes half closed and didn't try
to stop me as I moved up and kissed her on the lips. She kissed
me back right away, seeming more into it than I expected. I
almost backed out, but once she opened her lips to tongue kiss me
I quickly opened mine and pushed all her cum right into her
mouth. She shoved me away and sat up, making a sour face.

"Gross!" She said, wiping her mouth. "Why do you have to be such
a dick?"

I shrugged. "It's my job." She glared and I made a swift retreat
upstairs in case she decided to retaliate.

* * *

A week passed and Gail was still avoiding me. I had no idea why
she was acting so lame and it was starting to make me mad. Cassie
was out with her friends more often and I was getting pretty
bored hanging around the house by myself. One night I decided I'd
had enough, so I sneaked out. Technically I didn't really *need*
to sneak as there was no one there to catch me, but I didn't want
my skills to get rusty.

I went over to Gail's house and hid in the front yard. I waited
till it looked like her parents had gone to bed, then I crept up
outside her window and peeked in. It was open slightly and I
could see Gail sitting at her computer in her pjs, looking geeky
and cute as she adjusted her glasses. I tapped on the window and
called her name. Her head jerked around and for a second I
thought she was going to scream.

"It's me, Bobby," I whispered quickly, hoping that the rest of my
evening wouldn't involve police dogs and helicopters.

She relaxed a bit and came over to the window. "What are you
doing here?"

"I needed to talk to you. Can I come in?" I smiled, hoping that I
looked more charming than creepy.

She hesitated for a moment. "Ok. Wait a sec."

A minute later she opened the front door and let me in. We went
to her room and she shut her door and locked it.

"We have to be quiet," she whispered, looking nervous as we sat
down on her bed. "My dad would kill me if he found you here."

"Why? We aren't doing anything."

"Doesn't matter. He'd freak if he knew anyone was in my room this
late."

"Okay, so we'll be quiet," I assured her. "I just wanted to talk
for a minute. You've kinda been avoiding me."

Gail blushed and looked down. "I'm sorry. I just...I thought you
wouldn't want to see me again after...you know."

"Aw. Don't be a re-" I stopped myself before the rest of the word
came out. I was so used to talking to my sister that I'd almost
called Gail a retard.

"Don't be ridiculous," I said instead, mentally congratulating
myself on the save. "It's perfectly fine. Not even a problem.
Definitely a negative on the problemo scale."

She gave a hesitant little smile. "You sure?" She looked so cute
that I couldn't resist putting my arm around her.

"Super sure." Our eyes met for a second and then we were kissing
again, right back where we'd left off. Except this time we were
on her bed and her parents were home, so it also had the added
element of risk. Hot.

Gail's lips were cool and tasted slightly like toothpaste. For a
minute she didn't kiss me back but then she seemed to relax and
loosen up a bit, even letting me stick my tongue a little ways in
her mouth after she finally opened it.

I wasn't sure about her, but I was getting really turned on.
Especially when I thought about that dark mystery in her pj
bottoms, the legendary female vagina. Thanks to Cassie I'd had
experience with tits, butts, and even a dick, but authentic girl
parts were still a great and exciting unknown. Not that I
expected Gail to let me explore that far, but I liked to think
that anything was possible.

Right then I was concentrating on the possibility of getting to
touch her boobs. I rubbed along her side, feeling the softness of
her pj top and her warm skin underneath. She was kissing me
harder, seeming more and more into it by the minute. Right at the
same time that I got enough courage to put my hand on her tit she
caught my tongue and started sucking on it wildly. I squeezed
lightly at her boob, feeling my dick twitch excitedly as I
imagined her sucking on it the same way.

Before long I had both her small tits in my hands and was slowly
pushing her back on the bed. Everything was going better than
expected, despite the fact that Gail came millimeters away from
kneeing me in the crotch when she moved her legs apart so I could
lay on top of her. We ended up dry humping slowly and awkwardly
with our clothes on, my hand sneaking unchallenged under the
waistband of her pj bottoms. At first I encountered only bare
skin, then at last my fingertips touched the softest, curliest
hair imaginable, the fuzzy runway leading down to the promised
land.

Just when I thought I was cleared for landing, there came a
sudden knock on Gail's door.

"Time for bed, hon." A man's voice called. "Did you brush your
teeth?"

Gail shot up so fast that she headbutted me right on the nose.
Hard. I fell off the bed with a loud thump, literally blinded by
pain.

"Yes, Dad!" She said, almost in a panic. "Everything's fine!
Goodnight!"

There was a short pause. "Okay. Goodnight sweetie!"

Meanwhile I was lying on the floor, seeing stars and doing my
best not to bleed all over the carpet.

"Oh my God," Gail whispered, finally seeming to realize that
she'd almost killed me. "Are you ok?"

"What? Who are you?" I mumbled weakly. "Where am I?" I probably
shouldn't have said that, as Gail immediately began to freak out.
At least now I knew that she wasn't the type of person to count
on in crisis situations.

I got up and managed to calm her down before she could start
yelling. My nose did hurt like hell, though, especially when she
started shoving kleenex up there to stop the bleeding.

Gail apologized nonstop as she helped me escape out the window. I
promised to call her and staggered away down the street. My head
and my balls both ached, one from violence and the other from
frustration.

Cassie was home watching TV. She did a double take as I walked
in, then burst out laughing. Insult, meet injury. It probably
didn't help that I still had the kleenex stuffed up my nose.

My sister followed me into the bathroom, watching as I threw away
the tissues and examined my bruised and swollen honker.

"Well, don't keep me in suspense." She finally said. "What
happened?"

Even though I knew she'd just tease me about it, I told her.
Cassie giggled, snorted, then giggled again.

"I'm sorry," she said. "But you gotta admit that's kinda funny.
You got beat up by a 13-year-old *girl*. Maybe you should wear a
helmet next time, stud."

I sighed. Whatever. Gail was actually fourteen but I wasn't in
the mood to argue. I took some aspirin and went to my room to lay
down, eager to forget my humiliation.

I was dozing off when I heard the door open and saw Cassie come
in. She turned out the light and sat down on my bed, her warm
butt pressing against the side of my leg.

"Sorry for laughing," she said quietly, her face unreadable in
the near darkness. "So I guess you two are getting pretty serious
now, huh?"

"I guess."

"So you just wanna bone this girl? Or is it something more?"

I paused, wondering why she was asking all these questions. "I
dunno. I just like her."

Cassie sighed and flopped down on the bed next to me.

"She's lucky. I wish I had a guy who wanted to sneak in *my*
window."

I rolled my eyes. "They're probably afraid you'd beat them up."
She made my point by socking me on the arm.

"Ha ha," she said, looking up at the ceiling. "I'm serious. At
least you can get a girlfriend. Me? Most of the guys at school
won't even *talk* to me, let alone ask me out. And even if
someone did, what do you think he'd do if we were making out and
he reached down my pants and found this?" She smacked her hand
roughly between her legs. "He'd freak, that's what he'd do."

I frowned. Sometimes it was easy to forget just how different she
was. I was so used to the fact that my sister had a dick that it
almost seemed natural. Cassie, dick. Dick, Cassie. The two just
kind of went together, like oreos and milk.

"So?" I answered, shrugging. "Find a guy that doesn't care. I'm a
guy, and I don't care."

Cassie sighed again. "You're a perv. You don't count."

"Yeah, well there are a lot of pervs out there. You just gotta
find the right one."

We lay quietly for a minute shoulder to shoulder, both staring up
at the roof. Although there was no way in hell that I would ever
admit it to her, I thought Cassie was kind of pretty, sometimes
even hot. There had to be plenty of guys out there who'd like her
for who she was.

"Hey Knob," she said softly.

"Yeah?"

"Wanna show me what you and your little girlfriend did tonight?"

I started feeling warm as I pretended to think it over. "Sure."

She smiled. "I'll try not to headbutt you. But no promises."

I responded by rolling over and kissing her. Her lips were soft
and moist and followed mine almost like we were glued together at
the mouth. I went slow, replaying what I'd done earlier with Gail
as I rubbed my sister's shoulders and sides. Maybe I could
pretend to be Cassie's boyfriend for a while, at least till she
found a real one. The idea of it was actually kind of cool.

So was the way she was kissing me. I struggled to follow the
script as her hands moved down along my back and grabbed my ass.
I was already laying between her legs, one hand rubbing her tits
as I tried to keep up with kissing her. I let her have my tongue
and she started sucking on it just like Gail did. I wondered if
that was something that came naturally to girls.

I slid my hand up under her shirt, playing around with the
impenetrable fortress of her bra before giving up and reaching
downward into her pants. Her dick was stiff and practically
jumped into my hand. I tugged on it gently, feeling her suck even
harder on my tongue as I did. I had a feeling that we were gonna
end up doing a lot more than just dry humping.

As if by mutual agreement we both stopped at the same time and
pulled off our shirts. I could see the edge of one of Cassie's
nipples peeking out over the top of her bra, and she noticed me
staring and quickly squirmed out of it. Then she took her big
bare tits in both hands and started playing with them, hefting
and squeezing them as I watched, almost hypnotized.

"You like that?" She asked with a smirk.

"Yeah," I answered thickly, reaching out towards her. She let me
take over and I grabbed her boobs, rolling them around and kind
of knocking them together, enjoying how warm and soft and
resilient they were. Her nipples were hard and tickled my palms.
I swiftly came to the conclusion that tits were fucking awesome.

Cassie's cheeks were turning pink and she was starting to look
really turned on. I was so hard that I could feel my pulse in my
dick. The way I was leaning over her brought our crotches very
close together, and I moved in further until the stiff bulge in
my pants was rubbing against the slightly larger bulge in hers.
It felt good. Weird, but good. My sister started rubbing back
against me, seeming to agree.

I suddenly needed to find out how it would feel without pants in
the way. I got up and stepped out of my jeans, noticing that
Cassie was watching my every move, even staring at my cock as it
popped free of my underwear. I took her pants off next, working
them down over her hips until they slid all the way off. She was
actually wearing panties this time, white ones with little pink
flowers on them. The tip of her dick was poking out from under
the waistband and I could see a small wet smear of precum on her
lower stomach.

I climbed up again and put my dick next to hers, sliding them
against each other with only the soft cotton of her panties
between us. It felt awesome. I started rubbing harder, thinking
it might be cool to cum this way.

Cassie was really blushing now. She looked incredibly sexy laying
there under me. This was the first time we'd really done anything
face to face besides kiss, and instead of being weird it was
actually really, really hot.

So hot that I was moving up and straddling her head before I even
knew what I was doing. My cock was pulsing stiffly right in her
face, with me in the exact same position she'd been in when I'd
first sucked her off. I expected her to make some smartass
remark, maybe even push me away. She shocked me by immediately
taking my cock in her mouth and sucking at it almost frantically.

I gasped, putting my hands on the wall to steady myself as my
sister swallowed my dick. She seemed really into it, even putting
her hands behind my butt and pulling me in closer. Her mouth was
incredibly warm and wet, and after just a few seconds of watching
her lips move up and down over my shaft I was already on the
verge of nutting.

Cassie groaned as I started spurting off in her mouth, her soft
little moans only making me cum even harder. She held me tight
until I was done, then let go as I moved over and lay back down
on the bed, panting and drained.

She nestled up against me, resting her head on my arm almost
lovingly as she started playing with my hair. A minute later she
leaned in and kissed me softly on the mouth. I thought it was
pretty nice until she forced my lips open with her tongue and
shoved a huge wad of my own cum into my mouth, almost making me
gag. Shit. I should have known better.

"Urrgh," I groaned, rolling over to spit the stuff into my hand.

Cassie watched with an evil grin. "Payback is a bitch, huh?"

"Yeah," I responded darkly, still drooling cum into my hand. "And
so are you."

"Ouch, that stings." She rolled her eyes and rose up on her
elbows, no doubt to mock me further. "So what--"

Unfortunately the world will never know what my sister was about
to say next, because at that moment I took my handful of cum and
thrust it menacingly toward her face. She immediately shrieked
and jumped out of bed.

"Don't you dare!" She warned as she backed away toward the door.

I followed, still holding out my hand. "Come on. I hear its good
for your skin." She shrieked again and bolted out into the hall.
I chased her down the stairs, her in nothing but her panties, me
bare-ass naked; both of us giggling like idiots.

Cornering her in the kitchen, I managed to grab her wrist with my
free hand and held her still long enough to slap my cummy palm
right on the crack of her ass. She jerked away, her tits
bouncing.

"Eww," she said, stopping to feel her butt. Then she took a step
toward me, rubbing the jizz between her fingers. "Hey," she said
thoughtfully. "I bet this would look really great in your hair."

She chased me back upstairs. Our spirited game of cum-tag ended
in my room as she tackled me and swiped her sticky fingers across
my cheek and chin.

"Wow, you look younger already," she grinned. "Maybe it *is* good
for your skin."

I wiped my face and glared. Cassie let me up and sat on the bed
with a sigh.

"Okay. Truce," she said. "You got me, I got you. We're even."

"Fine." My eyes fell to her dick, which was still semi-hard and
tenting the crotch of her panties.

"Well, not *quite* even," she added as she saw where I was
looking. She flopped back on the covers and looked at me
expectantly. I wasn't really in the mood to suck her dick after
the stunt she'd pulled, but she did look kind of good laying
there half naked on my bed.

Feigning reluctance, I went over and started rubbing my hand up
and down along her thigh. Her skin was silky and warm. Just
touching her was making me hard again, and that made it difficult
to stay mad at her. Argh. Why did girls have to be so damn sexy?

I put my other hand on one of her tits and gave it a squeeze.
Cassie didn't move or make a sound. She just kept laying there,
seeming content to let me play around with her. She kept quiet
even when I gave her nipple a tweak, and, curious to test the
limits of her silence, I grabbed the waistband of her panties and
tugged them down over her legs. Her dick was fully hard again,
throbbing slightly as it rested against her stomach.

But I wasn't interested in her penis right now. I pushed her legs
apart so that I could get a look at her butthole. There it was,
right below her smooth little balls, dark and inviting. Acting on
a sudden urge, I ducked in and gave it a quick little lick. It
tasted a bit sweaty, but not bad.

I licked it again. Cassie gasped and drew her legs up toward her
chest, giving me better access to her butt. I think it was safe
to say that she liked it. I started poking my tongue at her ass,
the puckered hole relaxing as I licked deeper. It seemed like a
nasty thing to be doing, but I was hard as a rock the whole time.

Cassie's gasps and moans were getting me even hornier. Thinking
about how much I'd enjoyed fucking her last time, I stood up and
quickly put my dick to her butt. She was already wet with my
spit, and I gasped as my cock began to inch its way in between
the cheeks of her ass, slowly disappearing into her hot,
clenching hole. I started thrusting, shaking a little as I felt
her inner muscles grip down on my dick. So. Damn. Good.

My sister groaned, kicking her legs out wide and grabbing my
shoulders as I fucked her missionary style on my bed. Her tits
were wobbling and her eyes were closed tightly in a sexy frown.
Remembering that I was supposed to be her boyfriend, I decided to
be romantic and kiss her. I did and Cassie immediately bit my
lower lip, dragging it between her teeth. It hurt but felt kinda
good at the same time.

I repaid her by screwing my dick even deeper into her ass. Her
butt was squeezing me, jerking me like a clenched fist. I was
about to cum so I just plugged away at her as hard and deep as I
could, feeling my balls tensing up as they got ready to unload.

I came. My dick felt like it was turning inside out as I exploded
into Cassie's ass. A few seconds later she startled me by cumming
too, arching her back and groaning as her cock began to jump
without even being touched, her jizz shooting wildly out onto her
boobs. Even though I was still in a daze, the sight of Cassie
cumming all over her own tits was basically the hottest thing I'd
ever seen. And to top it off I was pretty sure some of it went in
her mouth. At least she couldn't blame me for *that*.

We were both panting as I slowly withdrew from her butt. I looked
down at the sticky mess on her tits for a second before leaning
in and licking some of it off of her nipple. Cassie shivered.

"Perv," she sighed.

"Yep." I grabbed her shirt and started cleaning her up, hoping
she wouldn't be too mad when she noticed there was cum all over
it. She lay there like she was half asleep for a while then
finally sat up, wincing as she swung her legs out of bed and
staggered off naked towards the bathroom.

I hopped into bed and stretched out, feeling much better. My nose
didn't hurt so bad anymore. I'd also cum twice in my sister, once
in her mouth and again in her butt. It was amazing just how much
something like that could lift your spirits.

I was almost asleep again when I heard Cassie's voice.

"Hey Knob, you forgot your blanket."

I rolled over blearily, wondering what the hell she was talking
about. Right as I did she tossed her cummy shirt right at my
face. It hit me with a cold, gooey slap.

"And wash that," she said, grinning. "Or I'll make you eat it."
With that she was gone.

I groaned, then turned over and went right back to sleep.
