It was a warm day. Warm enough for me to be wearing shorts and a
t-shirt. Mum was wearing a nice low v neck tee shirt
and a very short denim skirt that stopped about 5 inches above her knees.
All day i had been catching glimpses down the front of her top when she lent forward,
as the top was low cut with a couple of thin shoulder straps. She had big
creamy white breasts and her bra barely contained them and her big
brown nipples poked through her tight top. I even got a quick
glimpse up her short skirt and my dick swelled at the sight of her
white knickers. We had finished the shopping
and the heat off of the pavement was cruel as we made our way to the
bus. We had
to make a bit of run for it as it was already waiting at the stop. We
managed to
make it and I took the bags from mum while she paid for us. I wandered
down the
aisle to the only free seat. It was next to an old man who was sleeping.
Mum
followed behind me and stood in the aisle. I offered my seat to her but
she
politely declined it. We had been traveling for about five minutes when
she
changed her mind. Taking the bags from my lap, she plonked herself down
and
turned to me”I hope you don’t mind me sitting on your lap. I
figure
after all those years of sitting on mine, you owe me.”I didn’t
mind at
all, even though the heat from her body was making me even warmer. The
bumpy
movements of the bus was causing mum’s ass to rock against my crotch. I
tried
not to think about the sexual nature of it but I couldn’t stop. I could
feel the
swell begin in my pants and I knew Mum would notice it any moment. She
appeared
to be concentrating on the passing scenery so I tried to wriggle myself
out of
this sticky situation. My movements only made things worse as I felt my
erection
slide right between the cheeks of her ass. I’m not sure if Mum
was
uncomfortable with the situation or whether her short skirt was the problem,
but she
lifted her ass momentarily and smoothed her little skirt at the back. She settled
back
down, with my erection finding the groove of her ass straight away. Her
movements had caused her mini skirt to ride up at the front. My eyes were
glued to
her legs. They looked so inviting. I wanted to run my hands up them, but
I knew
it was inappropriate. I decided just to rest my hand midway along her
bare
thigh. I could get away with this innocently enough. Her skin was hot to
the
touch, but so smooth and soft. I nearly came right then. She didn’t pull
away
which calmed my nerves a little. I slowly slid my hand down her leg
until I
reached her knee, then slid it back up . It was more affectionate than
sexy, but
I went a little higher than I had been previously. I repeated this a
couple of
times until my hand was at the top of her thigh. The hem of her short skirt
was pulled
right up to her knicker line and I could feel the elastic of it through
the thin skirt. Mum’s eyes were closed but I could tell she wasn’t sleeping. The
movement
of her ass on my crotch had changed from the random bounce of the bus to
a
regular back and forth motion. She knew what was going on and for some
reason
she wasn’t stopping me. So I did what any horny young boy would do… I
kept
pushing my luck. I placed my left hand on mum’s waist and
slipped my
right hand under her skirt, resting it on her stomach. I gently traced
with my
index finger from her belly button down till i touched the top of her knickers.
They felt lacy as i scratched my way down the front of her knickers
feeling the heat as my hand covered her mound.
I followed the elastic around to her hip and along the side seam.
Again I followed the elastic around the seam of the leg,
this time ever so slowly edging closer to
her pussy. I could feel the heat emanating from between her legs. Her
underwear
was damp from a mixture of sweat and excitement. I ran my fingers along
the
valley in her knickers caused by her swollen lips. Mum squirmed, parting
her
legs and giving me more room. as my hand edged inside the leg of her
knickers. Her
soft pubic hair was dry on her mound, but as my fingers pressed into her
folds
it was wet and sticky. I separated her lips and slid my finger inside
her hot
pussy. She lent the back of her head against my neck and shoulder,
while I
stroked her inner walls. I withdrew and took her engorged clit between
my
fingers. Rubbing it and pinching it gently, she let out a soft moan into
my ear.
I took this as a sign that she was enjoying my attention. I pulled mum’s
body
back against me and then reached around between her legs to undo my fly.
Mum,
pushed my hand away and I knocked the old man sitting next to us. He
stirred
from his sleep, slowly opening his eyes. The first thing he saw was
mum’s parted
legs with my hand inside her tiny, wet knickers. He watched intently as mum reached
down
and undid my shorts revealing my hard cock. It sprang up between her
legs and
she grasped it around the base. Mom guided the throbbing head towards
her pussy
and with her juices and my precum to lubricate, she massaged her clit
with the
head of my dick. I moved my hand to cup her breast and could feel her
hardened
nipples through the material. She managed to keep her moans to a soft
whisper in
my ear.”Baby, you feel so good. Do you want to be inside
mummy?”I thrust my hips upwards and she arched her back, guiding
the tip
of my stiff cock inside her. With one movement she lifted and slide
right down
my shaft so that I was completely inside her. The man next to us watched
in
amazement while he rubbed himself through his pants. This turned mum on
even
more. She was still cautious not to alert the whole bus to our actions,
but she
ground her ass against me like she hadn’t had sex for years. One of her
hands
rubbed at her clit, while the other gripped my leg to give her something
to push
against. Just as I was getting close to orgasm she dug her nails into my
flesh
and shuddered. A groan that was slightly too load escaped her lips as
she threw
back her head. “Cum inside your mummy, honey”Her pussy
tightened
around my cock giving me the greatest sensation I have ever experienced.
I felt
the rush of sperm flow though me and inseminate my mother. I continued
thrusting
through my hot cum, and felt it combine with mum’s juices and pump out
over my
balls with each deep push inside her. Mum’s moan was enough to make the
people a
few rows either side of us look. They must have known by our closed eyes
and
flushed faces exactly what was happening. It was then that we came back
to
reality. Mum slipped her tiny knickers off of her legs and handed them to the
old man
sitting next to us. With a wink to him, she pressed the bell,
straightened her
dress and moved to the door. I quickly put my cock away zipped my shorts
and
headed towards mum. I could see my cum running down your leg but you
didn’t seem
bothered. She just turned to me and said “We’d better get home and
unpack the
shopping before your father gets in. I might need a shower!” And with
that we
exited the bus to walk the rest of the way. [/b]
