Judy’s Jewels – Part 1
by Ian Clifford

One summer, while a young man of eighteen, peter visited relatives who
owned a small ranch in the Texas hill country. The attraction of the
place was not the pleasant green hills and sparkling natural springs,
but rather his distant cousin, Judy, a buxom country lass about his own
age. At a brief meeting several months earlier, the sexually precocious
Girl had given the inexperienced youth his first lessons in making out,
in the back seat of a Chevrolet at a drive-in movie. Obsessed by the
memory of his adolescent seed spilling into her hands as Her fingers
slowly teased his virgin genitals, peter eagerly anticipated the visit.
The day after his arrival, Judy offered to show him around the ranch,
which was devoted to the breeding of cattle. After pointing out the
stock pens and some of the prize breeding bulls, She led him to a small,
clean building filled with equipment unfamiliar to the city reared lad.

“ This here’s our breedin’ barn. This is where we inseminate one of the
new cows to get them with calves. Also, with a sly smile, where we milk
the bulls.“

This last comment confused peter,

“ Milk the bulls — I don’t understand. “

“ I don’t mean the drinking kind. Where do you think we get all the
sperm for the cows? “ She giggled, “ Remember what I did to you at the
drive-in? “ Peter blushed in understanding “ Oh. “

Judy walked over to a stall beside which a large stainless steel machine
stood. “ This here’s the extractor. We lead the bull into this stall and
strap him down good so he can’t kick up a fuss. Then we stick this hose
on his pizzle and let it suck away on him till he creams. “ She held up
a clear plastic tube attached to the machine.

peter stared in fascination.

“ You mean it makes him ejaculate…just like… “

“ Yep, it milks away at their pricks until the shoot a load, just like
jacking off. I get a kick out of watching them. They don’t know what’s
happening but they sure know it feels good! “

“ Gee, do you do that to all the bulls ? “

“ Well, all the breedin” bulls. ‘Course the ones we don’t breed get
castrated. We do that in this stall too. Sometimes, Paw lets me work the
castrator myself, and he says I’m real good at it. “

peter shuddered at the callous cruelty in Her voice.

But his eyes remained fixed on the extractor. Judy played with the tube
in Her fingers, watching him out of the corner of Her eye.

“ The extractor don’t work just for bulls, you know. “

“ What…what do you mean? “

“ I came out here with one of Ma’s cocker spaniels once and caught the
hired man with his pants off and his prick in the extractor tube. He
liked it too, ‘cause he was gruntin’ just like a bull. I went and told
Ma what he was doin’ and She came out and ran him off with the cattle
prod, didn’t even let him pull his pants back on. “ peter’s lips were
dry as he tried to imagine the scene. She paused for a moment and then
asked,

“ What do you think it would feel like, peter, getting milked like that? “

“ I….I have no idea. “

She gave him a devilish grin.

“ Want to try it? “

He gaped open-mouthed at Her suggestion.

“ You mean….me….in the ….? “

“ Sure. I’ll work the extractor on you and you can see how it feels. I
know you like getting jerked off. “

“ Well….yes but. “

“ Then what’s the difference? C’mon pull your pants off and let me give
you a milkin’. “

If he were alone, peter would have relished the chance to try the novel
stimulation. But he was reluctant to perform such a humiliating and
bizarre sexual act in front of his adored cousin.

“ Judy, I couldn’t. Not with you….. “

“ Oh, don’t be such a chicken! Will you do it if I take off something
first? “ With that, She quickly unbuttoned Her work shirt and spread it
open. Peter gasped as Her enormous bosom was bared before him. Rather
than removing the shirt, She tied the loose ends beneath Her breasts,
lifting and framing them for his view.

“ There, I showed you my tits, so you pull down your pants. Go on now,
do it. “

At the sight of Her abundant Womanhood, peter felt all resistance ebb
from him. Almost in a dream he obeyed, fearing the loss of the heavenly
vision if he refused. Judy made him step out of his trousers and his
underwear until he stood before her naked from the waist down. Aroused
by the experience, his penis jutted stiffly in front of him.

She pointed at his manifestation and giggled,

“ See, you really want it don’t you? Come on now, get down on all fours
in the stall, like a bull. “

peter did as She asked, even allowing Her to fasten the restraints used
for the animals. As he knelt on hands and knees, She took two wide
leather belts which hung by rope from the ceiling and cinched them
tightly around his chest and stomach, forming a sling which supported
his weight. She then attached wrist and leg bindings which secured his
limbs to the four corners of the stall. He waited nervously, helplessly
immobilized, conscious of his naked organs dangling between his naked
thighs, completely at Judy’s mercy.

She gave his penis a flick with one finger and said sadistically,

“ You don’t exactly have the equipment of a bull, do you, little cousin?
This here tube might be a bit large for you. But that’s OK, ‘cause I’ve
got a small-size one we use for the cocker spaniels that Ma breeds. It
ought to be small enough even for your little pizzle. “

She chuckled, obviously amused by the humiliating comparison.

She attached one end of the smaller tube to the extractor and then
prepared to slip the other end over peter’s penis. But first she paused,
thoughtfully studying his organs.

“ You ever see an ol’ heifer about to be milked, cousin? That’s what you
look like right now. She’s got a big ol’ floppy udder full of milk.”

— She hefted his male sacks in Her palm —

“ and a long ol’ teat hanging down between Her legs, “

— she ran a finger lightly down the sensitive underside of his shaft.

“ You ought to hear Her moo, when Her sacks are real full and She’s just
begging somebody to squeeze it. “ She tickled the little tuck of skin
just below the head of his member, driving peter nearly mad with excitement.

“ You want me to show you how a country girl milks a cow, peter, how we
squeeze those tits in our hands? “

He cried in agonized frustration,

“ Please, Judy! Squeeze me. “

“ Well, I don’t know, little cousin, how bad do you need milkin’? I
don’t hear you mooing. Tell me how much you need it. “

peter bit his lip, trying to resist Her humiliating game. But the
teasing finger continued to torment his frenum, and finally he
surrendered all dignity, willing to do anything for the promised caress.

“…,…moo…oh Judy, milk me! Moo, MOO, MOOOO! “

Laughing, She grasped his penis in Her hand and began squeezing it with
a practised motion. peter moaned with pleasure and continued to imitate
the sounds of a cow for Her amusement.

After a few moments, She tired of this game and returned to the main
objective. She slipped his penis into the extractor tube and circled an
elastic band around the neck of his scrotum fastening the tube securely
in place. Then without any announcement, she switched on the machine.
Peter felt an indescribable sensation. It seemed as if the tube became a
living thing, a pulsating insatiable mouth, a creature thirsty for his
very essence, sucking hungrily at his organ even as a calf might nurse
at his mother’s teat.

Judy left the machine to work on his genitals and, going around to the
other end of the stall, sat down cross-legged in front of him. Her large
bare bosom was almost level with his eyes. He longed for his hands to be
free to feel it’s soft massiveness.

“ Feels good, doesn’t it, peter? “, She grinned.

“ Mmm…yes, it does… “

She leaned forward, bringing Her breast within inches of his face.

“ I bet getting sucked like that makes you want to suck on something
too, doesn’t it, little cousin. “

Her breast was only an inch from peter’s mouth, and the prominently
erect nipple jutted mote than half the space to his lips.

“ Please, Judy, may I? “, he begged.

In answer She only giggled and leaned forward. He drew the rosy bud into
his mouth as eagerly as a famished infant and began sucking. Judy smiled
to observe that his nursing lips matched perfectly the rhythm of the
extractor on his organ. How long he could have remained thus before
nature ended his rapture in an ecstatic release, none can say. For peter
was suddenly, without warning, doubly deprived as Judy quickly pulled
Her breast from his mouth and shut off the extractor. He groaned in
disappointment.

“ Hold your horses, peter, we aren’t through yet. I got something else
to show You. “

She walked over to a wall rack and took down an unfamiliar implement.

“ Know what this is? “

She held up an iron tool about two feet in length, looking like a cross
between a pair of fireplace tongs and a bolt cutter. She parted the
handles and pliers-like clamps opened at the end. peter shifted
uncomfortably.
