Your cock was beyond hard at this point. Even your patience had limits.

"Alba," You growled. "Use your powers on me. Now."

The beautiful young woman paused in mid-lick and looked up at the woman she was pleasuring for a moment. Her expression of urgency made her turn around on the spot.

"As you wish, but you might as well get comfortable," She recommended as she pointed to the white bed on the side. "This will take a while."

You took her advice and laid down. Then she placed her hand on your balls and closed her eyes. Immediately, you felt an unfamiliar jolting sensation on your sack. Then, her eyes opened and stared at you, clearly thirsty.

"I am making the brief but necessary alterations to make sure your sperm cells only produce female progeny for the next week or so," The horny psychic explained. "Now, I just need to keep it up until you finish filling up the tank and cum once. So...in the interest of speeding things up..." She trailed off, as you felt her heated breaths on your crotch, "I recommend you let us get you off."

You smirked, then turned to look at Kate, who was furiously frigging herself with a toy she must have borrowed from Laura.

Figuring she has been a good and patient girl, you motioned for her to get closer.

"You heard her," You stated. "Come and help her."

She didn't need to be told twice as she rushed to the bed while Alba couldn't stop herself from sucking your cock...and the pleasure convinced you it would be the first of many times to come.

You gasped at the feelings and then Kate got closer to the newly transformed bisexual and kissed her, tasting pussy and cock on her lips. Alba was a bit surprised at the unexpected liplock but it didn't take long for her to get into it and explore the redhead's mouth. All the while, you panted as you stared at their sapphic display of passion; Alba's hand never leaving your balls.

Eventually, they broke away and Alba sighed. "Your lips are so soft...and delicious."

Kate brightened and played with the newcomer's hair. "Thanks. I will be more than happy to help guide you through your new and improved sex life. But for now, I think we have to make our lover cum."

"Indeed," She said, her eyes sparkling. "Wanna team up?"

The insatiable woman chuckled. "Like you even have to ask."

And with that, the two of them started licking your cock with a vengeance,

You groaned loudly at their eagerness, gripping the sheets hard. In no time, you knew you were about to climax. So, you stood up in a flash and blew your load on their grinning faces.

They inhaled sharply, their faces wide with pleasure when your orgasm hit them, and once I was done, Alba finally stopped touching my balls.

"It's done," She said, sighing in contentment. "Based on multiple precedents, your sperm cells will be unable to impregnate women with your sons for at least a week as your baby batter will only make daughters. But, if you are serious about only having female children to more easily spread the psychic genes, I can recharge the process in 5 days just in case you want to be extra sure. "

You smiled at her warmly, lifting her chin softly.

"Thank you," You said, sincerely grateful. "Your ability to do this could actually play a vital role in saving humanity. And with that, let me tell you that you have more than earned your place in my harem. Will you marry me and share the rest of your life with me and the other members of my harem?"

Alba shivered at the idea and her eyes watered a bit. "As long as I can keep having sex with my fellow sister-wives and keep helping you impregnate them, then...yes. A million times yes!"

Your smile widened and you made out with your new bride intensely, feeling her heart quicken in the process. Eventually, you broke away and kissed her forehead.

"I promise we will consummate our marriage soon enough," You assured her. "But for now, I have an oath to keep."

And with that, you turned around to look at Emma, the teleporting psychic still enjoying the spectacle from the leather couch.
