Nothing crazy, just Becky.

"W-well," you stammer out "I want you to keep this a secr... a surprise." you correct yourself. "So, don't tell the rest of the family, alright?" you state.

"Really?" Elias says, clearly surprised by your want for secrecy. "If you want, I could tell all the girls downstairs to come up. you could impregnate all of them!" he continues, "Although, I'm not sure if Mom-"

"Sorry, Elias," you sharply interrupt, "I'll... get to them in my own time, alright?" you snap at your brother.

Your mind, now getting used to, or rather, drunk, on your new-found power, you look over to your sister-in-law-to-be, who was now looking at Elias with a little pity at your harsh treatment, but there is something very important that he interrupted.

Something you plan on continuing.

As Elias sighed and started to stand and turn to leave, you catch his attention.

"There is 'one' more thing I would like, as amends." you maliciously say as your hands start to wander up your engaged partner's body, ending with your hands kneading both her breasts, as you stare into her eyes, and started to grind your quickly rehardening member onto the hand that she had left on your thigh. She then turned to you with a surprised look in her eyes and mouthed, "You're back up?"

"Yeah, bro?" your brother spun around with a sparkle in his eye, probably hoping to make up for some of his perceived embarrassment both from his suggestion and his interruption.

Rebecca now changed her expression from that of surprise to confusion, probably wondering what else you want.

"To properly, and consistently, impregnate someone," you turn your head to him, "you need to... get to know them better." you say as your lips curls into a devilish smile.

He shifts from one leg to another, "What do you mean?" he says, as he tilts his head in a confused manner.

"I probably impregnated Becky when I creampied her," you smile, "But, to make sure, you can't fuck her, not until we're sure," you say, matter-of-factly.

You again turn your head to look at your naked partner and continue, "I'll be the only one to fuck her, for a while."

"That it?" he says, "Easy enough, we were planning to not have sex until marriage anyway, but..." he sighs in embarrassment, probably remembering when they first had sex.

"Also," you say as you lustfully look at your engaged prey, you lick your lips and say, "To ensure her pregnancy, I'll need to... watch over her, so to say; so she'll be sleeping with me for the whole stay here and when we go back home, too." You finish talking as you kiss your lover's flushed shoulder as you move your right hand from her breast to her pussy to start getting her ready for another penetration. Rebecca moans from your menstruations and moves her hand from your thigh to your now raging prick as her hand moves up and down on your dick.

"We- ahh! Well, I, for one, oh, think that's, fair!" Rebecca moans out as you continue to finger her.

You hear Elias sigh, seemingly out of the inconvenience of not having Rebecca to keep maintenance on their apartment, or make food; no, she'll be doing that for you, and more.

You pick up on your brother walking out the door of the spare room and close the door, and hear him walking down the stairs to meet your family.

Great, now you can finally get back to work.

You turn Rebecca's body so it's facing you and you start to kiss up her naked flustered body starting from her collarbone and ending at her lips with a passionate kiss.

You break the kiss and whisper into her hear, "You ready to get fucked, bitch?"
