Sit her down and talk

"My god Michelle, that was amazing."

Michelle seemed to have her composure back now. She stood up and kissed your cheek.

"Yeah, I don't know what came over me. I just knew I wanted to do that for you all day long at work. I don't know why. You seemed to enjoy it." She turned and walked down the hall toward the kitchen. She had a slender arching back and a soft round butt complete with dramatic dimples. Her hair was tousled from your manhandling, and as she sashayed away from you she had the look of a foxy bad girl. You paused to admire it before stuffing your tender cock away and following her.

She sat down at the counter in the kitchen where she had a bottle of red wine and two glasses waiting. She poured them and handed one to you. Hanging out around the house naked was pretty typical, even if throat-fucking ambushes were not. Michelle was comfortable naked and the two of you lived here alone in any case.

You took the wine and downed it almost in one. It was cabernet sauvignon, should have let it breathe a little, but you dreaded the talk you were about to have.

"John, is something wrong?"

You filled your glass yourself and swirled it in your hands nervously. You pretended to scan the bottle's label.

"You know how you said you didn't know what came over you?"

Michelle looked concerned.

"Well, I know. You've contracted the addiction."

She suddenly turned grave. "Oh my god... that's why... oh no,"

You took her hand and looked into her eyes. "We got the results back today. Michelle, I'm so sorry."

She took a drink from her wine and squeezed your hand tightly.

"I guess that's why I've been so horny all the time," she said.

"What do you mean?"

"I just get hotter and hotter, it's all I can think about. At a certain point it's like I can't even think anymore. Until, well, we..."

"That's dangerous, Michelle. It means you're nearing shock. You could slip into a coma."

"Oh John, what can I do?"

You finished your glass. "You have to drink semen. By the look of the results, it's probably a lot. Maybe even up to a cup a day, just to be safe."

"But John, I have to go to work, and so do you. Besides, you don't have a cup a day in there, right?"

I frowned. This is what I was dreading most. "Well no, no one man does."

"Can we freeze it? Are there like, donors or something? Or a synthetic substitute?"

I clasped both my hands on hers. "Not right now. It has to be fresh. we're working as hard as we can but right now there is no good solution. I will ejaculate for as many times as I can, but..."

"...but I'm going to have to drink some stranger's cum, is that it? John, I am not doing what I just did for you for a stranger."

"Michelle, you don't have to. You don't have to... touch them. All you need is to swallow their semen. Down at the center we have trained EMTs that respond quickly. These guys are professionals, alright? You just... just sit down and let them..." You couldn't say it. You couldn't imagine anyone, even one of our emergency staff, jerking off into your wife's open mouth.

"It's alright honey. I know. I just open my mouth and let them, release in there, then swallow it, right?"

You knew it. You knew somehow it would be the compassionate and level-headed Michelle reassuring you instead of the other way around.
