in former blogs i have already told you about the fantasies, in which i indulged, during masturbation
with my rubber foot pump.some of those fantasies related to my beautiful aunt. i will describe such
a fantasy to you, but regard, that this is just a fantasy, that i had during my pubescent masturbation
adventures.
the only thing that is true in that story, is that i had a crush on my aunt and that i masturbated with
my rubber air pump.

my aunt (the younger sister of my mother) has sneaked into my room, in which i masturbate with my
rubber air pump. i'm doing it like i do it every evening, when everybody in the house has gone to bed
and i'm alone in my room: i have forced the plastic nozzle of the air-pump-hose through my young tight
anus, then shoved the smooth rubber hose of the foot pump up my colon. then i have placed my excited
wet pussy on the soft rubber-surface of the pump. putting my full weight on the pump then lets me sink
down into the air filled pump, which forces a strong jet of air through the pump-hose in my anus bloating
my colon at once. i lift myself up, allowing the pump to expand again and fill itself with air.
again i let myself sink into the air filled rubber pump, again i feel my colon expand, again the rubber surface
of the pump caresses and excites my pussy that is diving into it, while i am going down. the up and down
movement of my body becomes faster and faster until i'm humping my pump like crazy. my anus tingles and
chews pleasurably on the pump hose, and my ballooned and overstretched colon itches blissfully and as every
evening i await the strong waves of multple heavenly orgasms, that come from the center of my ballooning belly,
filling my whole body and mind.
but that evening is different as for already some minutes my aunt is standing in my room, watching me. suddenly
i notice her. i startle, blush, tremble, feeling so ashamed. but my beautiful aunt comforts me: "it's ok anna. believe
me, almost all girls of your age masturbate. i have even seen some other teens on the internet doing this air pump
thing! just tell me anna, does it really feel that nice?" "it does!" i answer, feeling a little bit more confident now.
"then, you should continue!" my aunt replies, "don't mind me, just continue as if i wasn't here!" i'm still nervous:
"you wont tell my mum?" "no, i will not - this will stay our little secret. just something between you and me!" my
lovely aunt comforts me.
so i start humping my pump again, a little bit hesitating first, but then more and more passionate. that time it's
better than ever before as my aunt is watching me and i feel her coveting gaze on my naked skin.
i have secretely always dreamed of such a situation. in my wildest masturbatory dreams, it is my aunt, that is
pumping me up, pumping me up like a balloon, making me expand like a balloon beyond all limits until i burst - 
explode in a last overwhelming orgasm!
in my horniness i start to stammer: "pump me up, like a balloon, sooo big and round, make me burst, make me
explode into 1000 shreds!"
as i say that, i can feel my aunt's toes touching my pussy, finding their way between my pussy and the air pump
and my aunt starts helping me with the pump, her foot now doing the pumping, me riding with my pussy on her toes.
i grab her thigh and  my nestled my face against it, feeling the smooth nylon, she wears on my cheek and on my lips.
like that i enter orgasm-land, my aunt rythmically pumping me up, my ballooning belly itching like crazy, my aunt's
toes moving between my pussy lips, rubbing my clit and my vulva.

after endless waves of the most delicious multiple orgasm, she stops pumping and i let her go. looking down on myself
i see my belly protruding like a huge ball. it hurts terribly. but i feel only happiness.
"has it been nice for you, anna?" my aunt asks. i nod quickly. do you want to repeat it? i nod again. "wow, your belly
has become so big! amazing! you must be very proud of yourself!" i nod again, blushing.
"anna, i'll leave now. but tomorrow you must tell me more about your bursting fantasies!"
