End the study

You wake up on the final morning of your month at the resort exactly as you have every day for the past two weeks—face buried between your wife’s powerful thighs, sucking her giant shecock.

At 4’9” tall with hair cascading down to your plump ass and massive, heavy breasts that dominate your tiny frame, you feel like a living sex doll built purely for her pleasure. Your wife has grown into an absolute goddess at 6’ tall, with enormous H-cup breasts, wide hips, a thick ass, and a thick 9-inch shecock that hangs heavy over her perpetually dripping, horny pussy.

You start by licking long, slow strokes along her slick pussy lips, tasting her sweet morning nectar, before moving up to her morning wood. Your small hands can barely wrap around the thick base as you take the fat head into your mouth, sucking eagerly. She stirs with a deep moan, her strong hand resting on the back of your head as she gently fucks your throat.

“Good girl,” she purrs sleepily. “Suck your wife’s big shecock like the pretty little sissy you are.”

You moan around her shaft, bobbing your head as best you can, drooling and slurping noisily. Your own hidden penis—completely retracted inside its foreskin for the past two weeks—leaks constantly. Your balls are permanently retracted, each now the size of a small unshelled peanut according to the medical team. The constant leaking provides perfect lube for when she fucks your ass every night… and often during the day too.

She eventually grabs your long hair and thrusts deeper, flooding your throat with thick ropes of her morning load. You swallow every drop like the devoted sissy you’ve become, then bury your face back in her pussy until she cums again, grinding on your tongue and soaking your face.

Only then does she pull you up for a deep, loving kiss, her huge H-cup breasts smothering your own massive tits.

“Last full day, baby,” she whispers, fondling your heavy breasts and pinching your sensitive nipples. “Let’s make it filthy.”

The morning starts with a long, sensual shower together. You’re so short now that she has to lift you easily to wash you. She soaps up your massive tits, playing with them until you’re whimpering, then fingers your tight, greedy ass while you leak from your hidden little penis. You use your own precum as lube to stroke her massive 9-inch shecock until she bends you over and fucks you right there in the shower—deep, powerful strokes that make your huge breasts bounce and slap against the glass while you squirt helplessly from your prostate.

By the time you both dry off, you’re already glowing with that constant, humiliated arousal that never leaves you anymore.

Breakfast is served in the resort’s private couples’ dining room. You sit on her lap because the chairs are too tall for your 4’9” frame. She feeds you bites while her hard shecock presses between your ass cheeks under the table. Other transformed couples glance over with knowing, lustful smiles. Everyone here has been changed by the clinic, but your wife’s size and your extreme feminization draw the most attention.

After eating, you head to the final medical check-up. The doctors marvel at how complete your transformation has become. They confirm again that your balls will stay permanently retracted and peanut-sized, and your penis will likely remain an internal, hypersensitive nub for the rest of your life. Your wife beams with pride as she strokes her 9-inch shecock openly in front of the staff while they measure your massive breasts and tiny waist.

You leave the appointment leaking down your thighs. Your wife pulls you into a secluded garden path, hikes up your short sundress (the only clothes that fit your new body anymore), and fucks you against a tree. Her huge tits press against your back as she rails your ass, one hand reaching around to play with your sensitive nipple while you leak and squirt onto the grass.

“Such a perfect little fucktoy,” she groans, filling your ass with her cum before making you drop to your knees and clean her shecock with your mouth.

The afternoon is dedicated to the resort’s final “Intimate Sharing” event by the pool. You wear nothing but a tiny pink bikini top that barely contains your massive breasts and a thong that disappears between your plump ass cheeks. Your long hair flows down your back as your wife—towering and stunning in a barely-there bikini—leads you by the hand.

Everyone stares. Your wife proudly shows you off, making you sit on her lap again while her thick shecock rests against your leaking thong. During the open sharing portion, she tells the group how much she loves her tiny, big-titted sissy husband. She makes you stand up and show everyone how your penis has completely disappeared inside its foreskin, then bends you over a lounge chair and fucks your ass right there in front of the other couples.

You moan like a whore as her 9-inch shecock stretches you open, your massive tits swinging heavily while you squirt helplessly onto the chair. The audience watches with lustful fascination as she fills you again, then has you lick her clean while cum leaks down your thighs.

Afterward, she takes you to one of the private cabanas. For over an hour she uses you thoroughly—fucking your mouth, your tits, and your greedy ass in every position. You lose count of how many times she cums inside you or on you. Your own constant leaking and prostate orgasms leave you in a blissful, hazy state of pure submission.

As evening approaches, you share a romantic (and extremely filthy) dinner on your private balcony. She sits back while you ride her massive shecock reverse cowgirl, your huge breasts bouncing wildly as you fuck yourself on her. She reaches around to play with your hidden little nub through the foreskin, teasing the hypersensitive head until you squirt again and again.

After dinner you take one final walk along the beach at sunset. She carries you part of the way because your short legs tire easily. On a secluded stretch of sand she lays you down and makes love to you slowly—kissing your massive tits, sucking your nipples, then sliding her thick shecock back into your well-used ass while the waves crash nearby.

“I love you so much like this,” she whispers, thrusting deep and grinding against your prostate. “My perfect little 4’9” big-titted sissy wife. I’m never letting you go back.”

You cum hands-free again, leaking everywhere as she fills you one more time.

The final night is a marathon. Back in your suite she fucks you for hours—doggy style, missionary (with your massive tits bouncing in your face), standing while she holds you up effortlessly, and finally in a mating press that folds your tiny body in half. She cums inside you over and over until your belly feels slightly swollen and cum is pouring out of you with every thrust.

You suck her clean between rounds, licking her pussy and shecock until she’s hard again. She plays with your massive breasts constantly, slapping them, sucking them, fucking them. Your long hair is wrapped around her fist more than once as she face-fucks you.

By the time the sun rises on your departure day, you’re a cum-drenched, blissed-out mess curled up against her powerful body. Your massive tits press against her even bigger ones, her softening shecock nestled between your thighs, still leaking the last of her final load.

The month has permanently changed you both. You are now her devoted, always-horny, big-titted, tiny-dick sissy. And you have never been happier.

As you drift off one last time in her arms, she kisses your forehead and whispers, “Ready to go home and start our new life, my pretty little wife?”

You nod sleepily, already leaking again at the thought.
