   One Good Turn Bunyip

   Michael came into the bedroom unexpectedly and caught me driving my cock
up his sister's bum.  It was a kind of sex that was safe as far as
pregnency is concerned and she seemed to really go for it.  I had been
fucking her arse for months by the time Michael walked in on us.  Cathy was
obviously a bit wild and Michael had even seen her naked before.  He had
even caught us fucking before, but this time his jaw dropped as he focused
on where my cock was penetrating.

   Slowly but forcefully, I drove it into her, Time and again as Michael
watched us dumbfounded.  She was well lubricated with gobs of slippery
fluid from a tube she always carried in her purse.  "My God!" he exclaimed
as Cathy obviously rode through her second orgasm and I kept plowing on. 
"Don't look so shocked," Cathy smirked at him "It feels so damn good, so
hot, so tight, he fills me tight up and I can just about suck on him with
my grip, and it's delightfully naughty.  Don't you think!

   Michaelshook his head at her and said "Don't you think it's, well, just
wrong?"

   "Chris feels so tight in me that it feels like he's a superstud.  Don't
knock it till you try it!"

   Michael sat down and asked if she would be offended if he dropped his
cock out and wanked off.  She grinned "I've seen you jerk off before.  I've
even fiddled with myself watching you jerk off when you were twelve." She's
a few years older than Michael and I'm a couple of years older than Cathy.
Michael dropped his cock out, small but a little longer than mine.  Mine is
thicker by a long way though.

   With her usual twist between seriousness and sarcasm, Cathy said "Why
don't you fuck Chris up his butt while he's fucking me in my butt?"

   "What!" we both exclaimed together.  "Well you always ask me how it
feels.  Now's your chance to find out." Michael was listening and stroking
himself mindlessly.  I looked at him and although I can't remember what got
into me, I agreed.  Michael didn't move at first till Cathy told him to
lube up my butt and slide right in.

   I felt strangely arroused by the thought of getting my arse reamed, but
was not sure of whether I wanted to be labeled as "gay" or "bi".  Michael
later said basically the same thing; "Doesn't this make me a poofter? 
Doesn't it?  He plied my arse with the lube and even fingered my anus as I
rested my cock inside Cathy's arse for a few moments.  When he was sure I
was well lubed her pointed his bony, thin cock into my rectal foyer, and I
actually felt it's warm head as it pressed into my soft anal flesh.

   "Go ahead then.  I won't tell anybody.  You can bet on that!" He pressed
his skinny cock into my butt and it slid almost straight in.  I felt his
hot cock inside me and was amazed at how pleasant a sensation it was to
feel him sliding inside me.  He groaned and said "Oh dear God!" Cathy
giggled and I began slowly fucking her, grinding my ass on Michael's cock
as I did his sister.

   Michael joined in and pretty soon we were grinding away as a unit until
I felt Michael jolt to a stop and then felt his hot cum flood my arsehole.
It felt funny like hot bubbles inside me, like a hot fart trying to find
it's way out.  His body shuddered as he ejaculated and I just waited for
him to stop.  When he did he almost immediately pulled out of me and
stepped away as if embarrased at what he had done.

   I felt my open arse chill as the air hit it and then went back to
fucking Cathy who by now was heading into her fourth ir fifth orgasm.  My
hand was underneath her on her hand.  She had been fingering her clitty and
pussy for all she was worth.  When that one subsided she suddenly said "OK
stop, I want to see this.  I have got to see you fuck Michael's arse." I
slid out of her and said "What?" She said "Well I've had it done to me, and
now you have too.  I want to see Michael take it up the arse.  Michael it's
your turn!  bend over!"

   Michael didn't look amused but agreed as usual to his big sister's
supreme commands.  He bent over the back of the lounge and posed as if
surrendering his arse to me.  I felt like a thief taking him from behind
knowing that it was his sister's fettish that we were pleasing, not mine or
his.

   I lined up behind him and after a quick lube job I pressed my cock into
his arse crack.  He was a lot tighter than Cathy and somewhat more hesitant
but once the head was inside him he seemed to relax somewhat and I drove my
thick cock right up and into his tender, virgin arse.  Cathy walked around
us looking from every angle until she mused "Jesus that's hot.  I'm getting
off just watching you guys." as she fingered her slot over and over.

   Finally she stood behind me and I felt her thumb go into my butt.  I
could see in the cocktail cabinet mirror that she was fucking herself with
her hand, and my arse with her thumb in my butt.  She later told me she had
her first three fingers in her twat and her little finger slipped in and
out of her butt being not quite long enough to remain there.  As she
fingered, well thumbed my butt and I fucked Michael.  I soon came to
ejaculate into him and it felt even better than arse fucking Cathy, not
that I would ever tell her that!

   I spilt my load and then pressed my cock tightly inside his soft round
butt cheeks as I became uneasy about how horny I had become fucking another
guy.  I pulled out and his butthole was wide open looking like a rabbit
hole in his backside.  I slapped his butt and said "That's it, the first
and last time you get to fuck my arse my boy!"

   He smiled at me and said "Pity, I think I like that better than fucking
women."

   I shook my head at him and said "We all have butt holes, son, but only
women have sweet, sexy pussies to pound away at.  You had better remember
where babies come from!" and we all laughed as Cathy asked me whether I'd
like to finish fucking her arse.  I agreed with readiness, but suggested
that I needed a drink first, and a little time to become erect again.
   "Now that's worth waiting for!" she grinned.
