Did You Shrink?

You wake on Day 3 with a strange mix of horniness and unease. The serum has you feeling constantly aroused but something feels off down below. Your wife reaches for you first her hand wrapping around your cock. It feels smaller in her grip. Softer and shorter even as it hardens. She strokes you slowly and you watch her eyes widen slightly.

"Baby it looks smaller," she says her voice husky with excitement rather than concern. "But I feel incredible. My body is on fire."

Her words send a confusing thrill through you. She leans down and takes you into her mouth easily swallowing your entire length without effort. The sensation is intense yet humiliating. She sucks eagerly bobbing her head and swirling her tongue around your diminished shaft. You groan and buck but you already feel close to the edge. She pops off with a wet sound and straddles you guiding your smaller cock into her soaked pussy.

She sinks down fully with almost no resistance. Her walls feel hot and silky but the fit is looser than before. She rides you with long rolling motions grinding her clit against your pubic bone. Her fuller breasts bounce heavily above you. You reach up and squeeze them feeling how much plumper they have become. She moans loudly and rides faster clearly enjoying herself far more than usual. Her pussy clenches around your reduced size and she cums hard shaking and soaking your groin. The sensation pushes you over. You spurt weakly inside her with far less volume than normal.

Afterward you both look down at your shrunken penis. It looks pathetic now barely four inches hard and much thinner. Your balls have pulled up tight and smaller. Shame burns in your cheeks but your cock twitches again at the sight of your beautiful wife looking so radiant and horny.

At the clinic the measurements confirm it. Mahli measures your erect length at just under four inches. Your girth has thinned noticeably. Your balls have shrunk to less than half size. Meanwhile they praise your wife. Her breasts have grown to full D cups. Her ass is rounder and firmer. Her pussy shows increased sensitivity and natural lubrication. She glows with health and sexual energy.

Dr. Marcus explains the uneven effects. "The serum often enhances the female partner dramatically while reducing male genital size and output. Many couples find the contrast highly erotic. We recommend continuing unless you wish to stop."

Your wife speaks immediately. "We are continuing. I feel sexier than ever and I want to explore this."

The session turns intensely humiliating and arousing. They have your wife ride your tiny cock first for observation. She moans but you can tell it is not filling her the way it used to. Then Dr. Marcus steps forward. His massive thick cock looks enormous next to yours. He bends your wife over the table right beside you and pushes into her with one smooth thrust. She cries out in pure pleasure as he stretches her wide.

You watch every inch disappear into her pussy. The wet slapping sounds and her loud moans fill the room. Marcus fucks her hard and deep hitting spots you never could. Your wife looks over at you stroking your pathetic little dick.

"Stroke your tiny penis for me baby. Watch a real man fuck your wife."

The words destroy you but your shrunken cock throbs harder. You cum quickly spurting a small weak load onto your stomach. Your wife screams and cums hard around Marcus clenching visibly. When he finally floods her with a huge creampie she pulls off and sits on your face immediately.

"Clean me baby. Eat a real man's cum out of me."

You lick desperately tasting the thick salty load mixed with her sweetness. She grinds on your face and strokes your tiny spent cock until you twitch again.

Over the next several days at home the shrinking accelerates. By Day 7 your erect cock measures barely three inches and much thinner. Your balls are tiny and produce almost nothing. Meanwhile your wife blooms. Her breasts are now large sensitive DDs that bounce beautifully when she moves. Her pussy stays dripping wet and she cums easier than ever.

She becomes more dominant. She makes you watch her fuck herself with a thick dildo twice your current size moaning about how much better it feels. She sits on your face for long sessions grinding her superior pussy on your tongue while describing how real cocks stretch and satisfy her. She edges your pathetic little penis for ages teasing you mercilessly before allowing you a weak orgasm.

The next clinic visit introduces full cuckolding. A well hung volunteer with an eight inch thick cock joins. Your wife sucks him eagerly right in front of you taking him deep into her throat. Then she rides him reverse cowgirl so you have the perfect view of her stretched pussy lips gripping his shaft. She moans loudly the entire time.

"Look how much bigger he is. Your little dick could never reach this deep. This is what a real man feels like."

You stroke your tiny penis frantically as she cums repeatedly on the bigger cock. When the bull fills her with a massive creampie she sits on your face again making you clean every drop while she strokes your shrunken dick. You cum instantly from the overwhelming humiliation.

Your wife becomes more confident and sexually powerful while your manhood continues shrinking. The shame burns hot but so does the arousal. The therapy is reshaping your marriage in a way you never expected and part of you cannot wait to see how much smaller you will become and how many superior men your wife will take while you watch and serve.
