Berta
-----

Berta was at the bottom of the stairs to her condo when I arrived. 
She waved for me to roll down my truck's window, and told me to wait
five minutes before letting myself into her place.  Parking my truck,
I did what I was asked, wondering at the "emergency summons" I had
received just before lunchtime.  I gathered that she was horny but
other than that I didn't know what it was about.  Berta being horny
was about as rare as the sun rising each morning.

I let myself in and literally gasped.  Berta was standing in the
center of her living room, nude but for the strap-on she was wearing. 
Her hair was pulled back in a headband like I like (leaving her bangs
covering her forehead), her lips were vampire red, and her nipples
were extremely hard and jutting out.  But all I had eyes for was the
faux cock she was sporting.

It had been a long time since we'd had strap-on play.  That was my
fault.  In our last session, she'd penetrated me too abruptly and
caused a small tear in my pucker.  I'd lived with occasional blood for
a year, until she set up an appointment with me and accompanied me to
see my doctor.  The treatment was easy ("soft wipes" instead of toilet
paper) and I was fine after two months.  The day after the doctor
treated me, Berta finger fucked me as a test and we were both relieved
to find I had no issues.

That was a week ago, and since then she had teased me about the new
dildo she'd bought.  It was thinner than the really fat one I had
previously enjoyed, until she pumped the balls.  Then the damn thing
apparently would swell in girth until I was stretched open again.  Oh
my God I wanted that so much.

Yesterday, we learned I had achieved a longtime goal I'd set for
myself.  Berta had told me she would reward me if I did, and that was
part of my motivation.  "I'll give you a super big treat" she had said
back then, and I had expected her to forget.

But now I was peeling off my clothes and kneeling before her jutting
cock.  I could think of no bigger treat than to be her butt slut
again.  It had been a long time since I had even tasted a dildo, but I
fell-to with a hunger and soon was listening to her praising coos. 
"Good job, bunny.  Suck my dick."

I did for several minutes, until she told me to stand.  My cock was
parallel to my stomach in anticipation.  She was going to lead me into
the bedroom and sodomize the bajeezus out of me, I just knew it.  But,
I was wrong.

Instead she fastened my hands together with a rope and led me to her
coffee table.  Then she put a sleepmask on me so that I was
blindfolded.  Next she tied my hands to one leg of the coffee table. 
"I'll have to trust you to keep your butt up and knees apart," she
told me.

"Oh, please baby, just fuck me," I begged.

"In a minute," she laughed, bemused at my eagerness.  "Spread those
knees apart."  I did as I was told, and she grasped my nuts, making me
gasp.  Then she wrapped the free end of the rope around my sack,
pushing my balls far away from my body.  It was our way of ensuring
that I wouldn't cum no matter how much pleasure she gave me.

About then, I heard a knock on her door.  Her voice told me, "From now
on, I just want to hear 'Yes Ma'am.'  OK?"

I wanted to groan with need.  Instead, I replied, "Yes Ma'am."

"Hey, come on in," I heard Berta say when she opened the door.

I heard someone gasp at my predicament, and then whispering.  I
gathered she didn't want me to hear his voice.  Did I know him?

"Now why would you think I was bullshitting?" I heard Berta laugh. 
Berta is a worldclass bullshitter, so her protest was pretty funny. 
Then her voice turned serious, if not aroused, when she told him,
"take off your clothes and watch while I get him ready for you."

It was then that the perversity of her plan became apparent.  She was
going to use the strap-on with me to soften me up for a real man!  She
told me she knew I wanted a real cock whenever she fucked me, and the
last time I told her I'd get fucked for her--if she wanted.  Cruelly,
she then denied my orgasm until I told her I was desperate for a real
man in my ass.  At the time I was sure I had lied in order to find
release.  Now... I wasn't so sure.

I felt a cold jolt of lube on my browneye a split second before I
heard the spurt.  Then her female finger eased into my opening. 
According to our custom, she spent several minutes finger fucking me
with a single finger while working plenty of lube into me.  "Ready for
another?" she asked.

"Yes Ma'am," I said.  She slid another manicured finger into my butt,
pumping and twisting to loosen me up.  When I had been torn she had
reduced the time she'd spent preparing me, so this time she spent even
more time until I literally was whimpering.

"I'm going to fuck you now," she announced.  Then, solicitously, "OK?"

"Yes Ma'am," I moaned.  I was ready for the pleasure of the strap-on. 
There is nothing quite like getting sodomized, and I had missed the
sensation.

When she slid her prong into me, I barely noticed.  It was just a
little bigger than the fingers that had corkscrewed into me.  The main
difference is that it was much longer, and now opened my depths.  It
was hard--impossible!--to suppress a guttural moan Berta as filled me
again after such a long hiatus.

One thing I like about how Berta humps me is that she puts her weight
on me.  I have this feeling like she is giving me every bit of the
dildo, because her hips are mashing into mine.  When she uses a bullet
vibe on me, I couldn't tell as well since all there was as a signal
was her fingers.  But when her hips are fully on my rump, her pubes
circling to grind it into me (and also to grind the harness against
her pussy, which gives her pleasure) I know I am taking all her cock.

At one point, she held a one way conversation with my future male
lover, calling his attention to how much I loved it.  As evidence, she
kept asking me if I wanted it harder, to which I dutifully grunted,
"Yes, Ma'am!".  Eventually, she grabbed my hair and pulled me into her
thrusts until she was tired.

I thought she was done, and got all tingly thinking of this stranger
giving me my first live dick.  But she wasn't.  She reached down and
gripped my balls, squeezing them significantly.  Then, she reached
down and squeezed her own balls, thereby inflating the dildo some. 
Suddenly, my sphincter was stretched open.  "Do you like it?" I heard
her ask hoarsely.

"Yes, Ma'am," I said although I was not sure I did.  When she pulled
out to add lube, I could feel my butthole collapse.  Moments later she
re-entered me, stretching me again.  Oh Lord, it felt so good!  I had
missed it so much.

I put my head down and just felt her fucking me.  What a gift she was
giving, expending her energy for my pleasure.  Over and over and over
she thrusted, filling me and rubbing my insides, bumping my prostate. 
She said she loved me, and in the back of my mind I knew it in the
fucking I got.

Finally, she was tired and wanted to give my ass to this man before I
got too sore.  "You ready to fuck him?" she asked, ignoring whether I
wanted it or not.  "Look at his asshole... so red and gaping."  I
could only imagine what I looked like, my mental image formed by porn
movies of starlets enduring extended ass reaming.  My loosened opening
would gape, a red rim around a ready dark cave.  He could stick his
finger in me and not even feel my opening.  That's the image I had in
mind, and when I heard Berta's camera turn on and the zoom extend, I
knew I would see my status afterward.

"Now, stick your cock deep into his bowels," she told this man, being
intentionally nasty.  "Fuck him hard enough so that your balls slap
his!"

I steeled my nerves, knowing that I would soon have a warm, live,
pulsing cock buried in me.  I would soon lose my hetero-virginity,
officially having my first man even though I was unable to stop it. 
This man would take something I had been too scared to give freely for
two decades.

I felt his hands on my rump, his fingers strong and rough.  I moaned
loudly, my ass clenching as I readied myself for him.  His thumbs slid
into my butt crack, prying me open.  I could sense his position shift,
and knew he was about to plunge into me.

"Yes!" Berta hissed, "shove it into him."

But then something happened.  I heard a groan and his voice clearly
said, "Oh No!"

I felt red-hot splashes on my butt and a flood of liquid pouring into
my gaping asshole.  Berta cried out, "No! No! No!" and then a
resigned, "Oh FUCK!"  I knew in a flash what was happening.  The
stranger had cum prematurely, soaking my ass with cum instead of
fucking me.  Judging by how sloppy I felt, he had cum a bucket.

After that, I had the feeling Berta was hurrying him out of the door. 
She kept reassuring him that it was OK, she understood, perhaps
another time, etc.  But when the door was closed and locked, she
groaned and said, "Fucking Loser."

As she untied me, she apologized.  "I'm sorry baby," she said, "I
wanted to give this to you as a special surprise."

"It's OK," I laughed, feeling sloppy and abused in my ass.  "I love
you for the gift you intended."

"I just knew you wanted it," she said, finally freeing me completely. 
I held her, telling her that it was the thought that counts.  "How
about I make it up to you?"

"How?" I asked.

"Since he didn't cum in you, how about you cum in me?" she suggested. 
It was a lewd suggestion, because I knew the rules to this activity
too.  She would have to go back to the office, so I would have to suck
my cum from her after I filled her up so that she didn't leak all over
her seat.

I rolled onto my back, showing her my erection.  "I'd like nothing
better!" I agreed.  Five minutes later, her sloppy pussy was settling
on my mouth and I proved that statement true.
