The odd-numbered parts have the sex. The even-numbered parts have the love story.

Francie likes what she's seeing -- her feminized husband.
All slutted-up in strappy heels and frilly socks, a cute cornflower blue skirt and white cotton blouse, kneeling in front of the living room couch, sucking off one of Francie's boyfriends.
Francie (wearing nothing but her glasses, pajama bottoms and a dirty smile) watches the little butt wiggle, the girly head bob, the tied-back ponytail swish. She parks her own little butt on the edge of the couch, swishes her own ponytail, closes her eyes and listens to the gurgling and slurping.
Francie pinches a nipple and slides the other hand down her pants. She's been wet since those two started playing with each other.
She pushes her glasses back up her nose and leans in, to see if the slut's getting that cock all the way down. Francie herself can barely do it...
And the horny thing's swallowed it almost all the way to the root! Francie doesn't know whether to cheer or be jealous. But as the last inch is about to disappear, the slut gags and gets wide-eyed; she backs off, leaving a shiny coat of drool behind. Francie watches a string of the stuff stretch out between her boyfriend's cockhead and her husband's pretty lipsticked mouth.
There's a tiny *koff!* and a *sniff* and a deep breath. Tears well up in the gurl's eyes from choking, but she runs her tongue over her lips, opens that pouty mouth wide and slides back down.
Francie rubs herself a little more, then rolls off the couch onto all fours and scampers behind her husband. She pats him on his pretty ass.

After a few years together, Francie and Graeme were getting stale. They agreed that they needed a change, and they agreed on his suggestion of what to do.
But couples play didn't work out for them.
They loved the adventure and the variety, the extra attention, and -- oh the sex! -- Francie *loved* getting a proper fucking, and Graeme *loved* seeing his wife getting a proper fucking.
...which is where the trouble lay. This excited Graeme very much. Just the thought of Francie getting humped by another guy -- and he could hardly think of anything else -- drove him happily lust-crazy. And actually watching it... Well, that was *too* arousing, *too* distracting. Graeme couldn't pay any attention to his partner.
And if that wasn't enough of a turnoff for a woman, then Graeme's premature ejaculation certainly was.

Francie peeks under her husband's skirt and rubs a hand over the pretty lace-trim panties. The smooth bottom rolls this way and that, the sissy's body moves with each hand-stroke and head-bob on the thick cock. Francie hooks her fingers in the tart's waistband and pulls the panties halfway down.
And she sees a wet spot in the gusset! Oh, she knows it's just precum, but it sure looks a lot like a _real_ girl's wet panties!
Francie checks herself for a wet spot. She takes off her fogged-up specs and wipes them against her PJ bottoms. It's really steamy in here! She puts her glasses back on and reaches inside her pants. She covers a finger with her juice.
She touches her husband's hairless sack, tracing a line of girl-wet along that cute ridge on the underside. She pokes the taut skin gently, working a finger between the balls, tickling and teasing. The cocksucker starts making making 'mm-hmm' noises and wiggling her ass around, trying to get Francie's finger on the hole.
She teases him, she won't give that satisfaction. Francie has an even better tease ready: She squirts a little fruit-scented lube in her palm, waits for it to warm to body temp, then spreads her husband's asscheeks and dabs it on his anus.
Francie's mouth is watering, but it's not from the sweet smell of that slippery goo. It's because she's about to watch her husband's ass-cherry get popped.

The couples play and the swing clubs weren't a total failure for Francie and Graeme. Look at it the right way, and it was a tremendous success. What could be more exciting, what's more positive for a relationship, what's more fascinating than discovering something new, something unexpected, something very sexy about your 'other half'?
What Francie discovered is Graeme's cuckold fetish. What Graeme learned is that little Francie has a touch of domme inside her!
And now it was Francie's turn to make a suggestion. She proposed an "adjustment" to Graeme's marital privileges: they'd no longer be having sex with each other. Of course Graeme would watch her with other men and he would be... assisting.
As Francie expected, just talking about this new arrangement got Graeme excited ("visibly so", Francie pointed out -- while literally pointing at the cute little bulge in his pants). And she knew she'd have to do something to keep Graeme from being a such a naughty boy.
Francie bought Graeme a special present to makr this new stage in life, an adorable little chastity cage with a little bow and a heart-shaped lock. Francie promised strictly supervised masturbation on special occasions.
