Control

You came into the house through the garage, saw your wife standing in the kitchen with a look of panic on her face. "What's the matter," you asked, worried.

She swallowed. "She...I...she's here."

"She? Who's here?"

Your wife looked down. "M...Mark's mother."

"What?" you asked. "Mark's mother...Mark...Mark...like...like your Mark?"

She nodded. "She...she's in the living room."

"Why?"

"I...I have no idea," your wife said, "she just...she rang the doorbell and said she wanted to talk to you."

"To talk to me?"

"Yea," your wife shrugged. "I told her you weren't home but she said she'd wait."

"What's she want to talk to me about?" you asked.

"No idea," your wife said.

"What am I supposed to do?"

"Go talk to her," she said with a shrug. "I...I don't know."

You walked nervously to the living room, saw an older but very attractive woman sitting on the couch. She wore a white skirt and jacket with a sheer blouse, nude hose, heels. 

"Angela's husband, I presume."

"Y...yes," you said nervously. "And you are..."

"Your wife told you who I was," she said, looking you up and down. "Well this explains so much."

"About...about what?"

"Why your wife and my son are lovers," she said. "I assumed she traded up in the masculinity department, I suppose I didn't realize it was this much."

"What's that mean?" you demanded, uncomfortable with her confidence. 

"Did she catch you in panties before of after she met him?"

"I don't have to listen to this," you said.

She narrowed her eyes. "When I ask a sissy a question, I expect an answer," she said, an obvious challenge. "Panties before or after?"

"B...before," you whispered, still shocked your wife's lover's mother was sitting in your living room.

"That makes sense," she said, "most women end up desiring a masculine lover when they learn they're married to a sissy."

"I...I never..."

She held up her hand, silenced you. "I'm not here to discuss your lingerie, not today anyway, I'm here to discuss more important things."

"What...what more important things?"

"I admit taking certain liberties, as a mother, favoring my son, of course, so we can start with that."

"Start with what?" you asked, confused.

"Monogamy," she said.

You looked down, face red. "We...we have an open...an open relationship," you said.

"Not your monogamy, my son's."

"I...I don't understand, he...he knows my wife is..."

"Married, yes, yes. Don't be dense. My son is involved with your wife; I expect monogamy."

You looked at her strangely. "But she's married."

"Yes, of course. Let me put this plainly. My son fancies your wife, obviously, my interest, as a mother, is making sure the woman in his life is faithful to him."

"You...think she'll divorce me?"

"Of course not," she said, "nor would I suggest it, encourage it, or endorse it. But what she will do, what I'll make sure of, is that she has sex only with him. Monogamy."

"She dates him, no one else," you said.

"Sissy, I'm talking about you."

"Me?"

"My son tells me you still pester her for sex. Understandable, of course, but entirely preventable as well."

"Preventable?"

"We'll have you fitted for a device...a chastity device...I'll control access, of course. Wives sometimes feel an emotional pull and will give in and unlock their husband. As I said, we'll have none of that; so long as they're together, you'll be caged."

"You're serious?" you gasped.

"Completely. Don't worry, you'll come to appreciate it; the loss of orgasms usually makes a cuckold feel more emotionally close to his wife, trading physical for emotional. Trust me, it's for the best."
