She'll find out eventually anyway

You decide it's best not to delay what is likely inevitable. Maybe, once she calmed down, she'd be able to think of something you hadn't. If nothing else, your ankle really needed to be looked at. With your belly in the way, it was impossible on your own right now.

Deciding it wasn't even worth the incredible effort and gymnastic feats it would take to make yourself decent in this situation, you limped off towards the stairs. Between your ankle and the huge shift in your center of gravity the endeavor took quite a while. By the time you'd finally reached the bottom steps, your mother was finishing up with lunch preparations in the nearby kitchen and mumbled something to herself you couldn't quite hear.

She was a small woman, a few inches shorter than you, but otherwise you were almost a carbon copy. Her apron obscured her DD-cup breasts and the wide hips, but you knew it well enough. She'd lost some of the tone and perkiness of youth, but had replaced it with grace and the sultry allure of a more mature woman. You briefly wondered why all this passed through your mind now of all times, but

She walked out towards the stairwell, calling out to you as she set the last few things down. "Naomi! Are you planning to just sleep the day awa-oh my GOD!" She dropped the serving spoon, it clattering to the ground in the sudden silence. She stared at you, agape, her eyes slowly fixating on your pregnant belly. The extra weight and the pain had really tired you out up to that point, but you seemed to perk up slowly as she stood there.

"Mom...I... This is probably exactly what it looks like. I don't know how it happened so fast either." Her eyes are wide as you guessed her brain was trying to match what she'd seen of you yesterday and how you looked now, her mouth moving open and closed as only incoherent sounds seemed to come out. Unable to think of any way to soften the blow or make the whole things sound less crazy than it was, you just started blurting out the whole thing.

By the look on her face, you weren't sure how much of the story she actually heard, but you were sure of one thing. Your cunny was leaking juice down your legs at an alarming rate as you relived the events. To your own surprise, the story turned from one of violation to an almost glowing account, and then to a play by play of how hard that thing had made you cum.

Even as the horror was still with you, some part of your brain seemed to have loved the experience. It loved the thing that was growing inside you. It also seemed to enjoy a sudden unexpected rush inside you. Something was changing in your body.
