The Sire Program

She wants a baby, not a husband, so she signs up for a private program that matches her with an anonymous donor. They meet masked, and it’s supposed to stay that way. The Sire Program is a series of standalone masked breeding romances where the man behind the mask falls first and the ending is always happy. All Piper Kane books are free in Kindle Unlimited.

Pick Me

She chose him off a page. She chose him again in the dark. She had no idea they were the same man.

Bree Kim is thirty-six, successful, and done waiting for the right man to show up with a ring and a timeline. The Sire Program offers something better: vetted donors, anonymous encounters, and a baby with a father who actually wants to be one. She selects Donor 09 for his genetics — height, health, athletic build — and a psych assessment that says “protective without possessiveness.”

She has no idea what that looks like at six-four and two-forty.

Gage Moran is a retired MMA champion with scarred hands and a voice that makes her grip the sheets through her mask. Three visits. Three ovulation cycles. He adjusts everything to her scale the first time. He stops adjusting the second. By the third, he’s whispering things through the mask that have nothing to do with conception and everything to do with keeping her.

The masks come off. She sees his face for the first time in a coffee shop. She recognizes his hands first.

He recognized her the moment she laughed.

Choose Me

I wanted a baby. I did not want a husband, a setup, or a year of dating to get one. So I found the program that lets you skip all of it — and the last question on the form asked what I actually wanted, in my own words, no one watching.

I sat with that blank field for an hour. Then I wrote two true sentences and hit submit before I could lose my nerve.

They sent me two profiles. I opened the second and saw one word — widower — and said yes.

He comes to me masked. I never see his face. The first time, he went down on me slow, took his time, and when he finally pushed inside he said feel how full you are like he was telling me something true. When he came he spread both hands flat on my stomach. Keep it. All of it. I put my hand on the back of his neck without deciding to. He went completely still.

Neither of us moved for a long time after that. I’m not supposed to want to know who he is. I want to know everything.

Choose Me is a contemporary instalove romance — an anonymous program, a masked widower, and two strangers who chose each other before they ever saw a face. Standalone with full HEA and pregnancy epilogue.

Kinks and tropes: Anonymous masked encounters • Donor program • Widower hero • He fell first • Breeding kink • Clinical setup, devastating delivery • Instalove • Pregnancy HEA

Don’t Find Me

The whole point of the program was that no one would ever look at me too closely. That was the part I needed most.

I’m an attorney. I spend my days being measured, graded, watched to see if I get it right. So when the form asked what I wanted, I wrote three lines I’d never have said out loud: From behind. No eye contact. No praise. One hour that wasn’t a performance. One hour nobody was scoring.

They matched me with Cole.

He arrives masked. He honors my card to the letter — every line, exactly. He gives me praise once a visit and not a word more, low and deliberate, like he means it instead of forgetting to stop, and my whole body goes quiet every time. I came in for a clean transaction with a stranger I’d never have to see again.

I’ve started staying later than the visit requires. He’s never once asked me to leave. And the program promised us anonymity — right up until I find out exactly who’s been on the other side of that mask.

Don’t Find Me is a contemporary instalove romance — an attorney who asked to be left unseen, and the masked match who paid closer attention than anyone ever has. Standalone with full HEA and pregnancy epilogue.

Kinks and tropes: Anonymous masked encounters • Donor program • Praise as the kink • Attorney heroine • He fell first • Breeding kink • Same-world reveal • Instalove • Pregnancy HEA

Book cover for Come Back to Me by Piper Kane (The Sire Program series)

Come Back to Me

I wrote three words on the form the program calls optional: Open to direction. Everything else I actually wanted, I couldn’t get to fit on the page.

I’m thirty-seven, and I know exactly what I want — a baby I choose, not one I arrive at by accident. What I didn’t want was small talk, dating apps, or one more disappointment. So I answered the questions honestly, agreed to a program where the sire and I would never see each other’s whole faces, and sat in a warm suite in a leather mask on a Friday night, waiting for a stranger.

Then Roman called. My match had withdrawn before he ever walked through the door.

A week later, Roman called again. The same man was asking to come back — and when the door finally opened, I understood exactly why he’d almost run. His hands on mine. His voice. Everything about him said yes before either of us said a word.

What he never told me — not that night, not across three masked visits and a promise I could still feel for days after — is that he already knew who I was. My name. My restaurant. The dining room he was undoing me in, he’d built for me three years before we ever met behind a mask.

He let me fall for a stranger who was never really one.

Come Back to Me is a contemporary breeding romance — the masked sire who recognized her the moment she said one true sentence, and kept coming back anyway. Standalone with full HEA and pregnancy epilogue.

Kinks and tropes: Anonymous masked encounters • Donor program • He knew her first • Breeding kink • Contractor hero • Same-world reveal • Instalove • Pregnancy HEA

Book cover for You Already Know Me by Piper Kane (The Sire Program series)

You Already Know Me

I picked a masked stranger to give me a baby. He already knew my name, my voice, my whole life.

The Program is simple.

You want a baby, not a relationship. You pick a donor from a profile. You never see his face. Three visits, and you walk away with the only thing you came for: a pregnancy.

I’m a documentary filmmaker. I spend my life safe behind a camera. Choosing the Program was the first honestly selfish thing I’ve ever done—a way to have what I want without handing anyone the power to leave.

His mask stays on.

But from the first visit, he’s uncanny. The way he already seems to know how I like to be touched. The way he lets me set the pace, like he’s done this exact dance with me a hundred times.

Because he has.

Finn has lived in my building for a year and a half. Shared my elevator. Fixed my Wi-Fi at a party I don’t even remember.

He recognized me the second I walked in. And he said nothing—because he’d rather have me like this than not at all.

I don’t figure it out until the mask slips and I see the scar I’ve passed in the hallway a dozen times.

The stranger I picked to be nobody already knows everything.

A steamy, tender romance with a masked-donor premise, a quiet hero who fell first and kept the secret, and a slow reveal that changes everything. He’s been hers the whole time.

Hate That It’s You

I’ve hated Jake Mercer for two years, and I’ve never seen his face.

He runs our New York office. I run Chicago. Every week he sends me a perfectly polite email that guts me, every week I write back something meaner and funnier, and half the company reads our threads for fun. Now the family is deciding which office survives, and he’s the man standing between my team and a stack of severance letters.

What I actually want is a baby, and I’ve stopped waiting for a man to come with one.

The Sire Program matches me with a stranger. We meet in a suite in a brownstone, both of us masked, no names, nothing between us, until it takes.

I wrote down exactly what I wanted on the form. I never expected anybody to give it to me.

He does. He pins my wrists in one big hand and barely says a word, and for the first time in my life my head goes quiet during sex. Afterward he keeps a hand low on my stomach like he’s already guarding something. When I make a dry joke in the dark, he laughs, and I feel it all the way through me.

I’m falling for a man whose name I’m never supposed to know.

Then the company puts everyone in one room for the first time, and I look across the table at Jake Mercer.

I know that mouth.

And from the way he goes still, he knows exactly who I am.

An enemies-to-lovers masked breeding romance with a two-year email war, a rival who is nothing like his emails, and a pregnancy HEA. Standalone.

Book cover for Doctor’s Orders by Piper Kane (The Sire Program series)

Doctor’s Orders

Dr. Roman Hale co-founded The Sire Program. He’s approved hundreds of matches and never entered it himself, until his partner calls him on it and picks a match for him.

Margot Deveau is thirty-seven, divorced, and wants a baby with no husband attached. She chose the program because nobody has to know her name.

They meet twice, both of them masked. Roman has kept control of everything for fifteen years, and with her he can’t hold on to any of it.

Then he takes off his mask on purpose, because he can’t stand her not knowing it’s him.

He just broke the one rule she signed up for: nobody learns anybody’s name.

A masked breeding romance with a controlled doctor who comes apart, a heroine who wanted a baby and nothing else, and a pregnancy HEA. He falls first. Standalone.
