It's the Fourth of July and time for a bang.

I awoke with a satisfied groan as I could feel my morning wood harden inside my niece. We had fallen asleep so fast after last night's fucking that I hadn't even managed to pull out. Not that it mattered now. I rolled us from our position on our sides to her laying face down and me pushed up behind her. She made a cute little noise at the movement but seemed to still be asleep. That was fine, she'd wake up sooner or later. I worked a slow easy pace in and out of her as I warmed myself up.

Suddenly a loud bang caused me to jerk suddenly, waking Sara with a yelp. I looked around the room as another bang went off. I realized they were from outside. Then it hit me. It was The Fourth of July, and obviously, some kids were getting an early start. Deciding to ignore them I resumed my leisurely fuck, my teen niece beneath me groaning as she rubbed her face into her pillow. I relaxed my weight a bit on top of her seeing as she was awake and I didn't need to worry about keeping her asleep. This drew another whine of protest that I ignored. You'd think after a month she would have gotten used to her pussy getting fucked by her futa aunt's hard cock near ceaselessly but Sara seemed pretty stubborn about not enjoying herself too much.

God had it been a month already? Time really flies when you're fucking like a horny teenager every single day. I wrapped my arms around my niece's head in something of a headlock as I began to really pound into her. My nuts were getting tight and I wanted to blow my wad quickly. A few hard thrusts into that teenaged cunt and I exploded hard. After giving myself a moment to enjoy the afterglow I rolled off the girl and laid back to catch my breath.

One look in the room would tell you that it's been a busy month. The smell of sex alone hung in the air so thick you could nearly cut it with a knife. On top of that, there were several telling stains on the carpet and even one or two on the wall when I took her pressed up against it. Still, one full month of hard fucking one girl (with only the occasional breaks to fuck her best friend or one notable weekend, my sister) was starting to get me feeling restless. Luckily there was a chance to break up the monotony.

Sara's little cheer team was having a farewell BBQ and sleepover for the holiday. Since this was the biggest house and had the least amount of supervision they were holding it here. It was seniors and thanks to a well-timed call to their parents I ensured it was just the girls coming. A few school friends might stop by, but absolutely no boys. Nothing but a sea of barely legal teens for an entire day and night. My cock was already stiffening at the thought. With that in mind, I rolled sweet Sara over and lifted her legs by her ears, matting press style.

"Excited about today?" I asked as I slid back inside.

"~Ohhhnn~ I guess," she mumbled, still half asleep. "Be nice to see everyone, though us all getting fucked by you might be ~guhh~ embarrassing."

"You...t-think? What's so embarrassing about taking my cock?"

"I dunno. I know it's n-n-normal but ~hsss~ being all naked in front of the team is weird."

"Just pretend it's a locker room," I suggested before kissing her on the lips and groaning into her mouth. After a minute of making out I pulled back and smiled. "Can you believe a month has gone by?"

"It's only been a month?" She asked before she whined from a sharp thrust by me. I wasn't a fan of the back talk.

"Speaking of did you ~fucking hell~ get a testing kit?"

"Not yet, I ~ughhh~ sort of don't want to know."

"It's going to be positive sooner or later," I told her before putting her right nipple in my mouth and sucking on it. She just gasped before groaning in despair at that thought. Sara was still not thrilled about carrying my bastard child inside her womb or having to care for it with no support from me for the next 18 years. It might be normal for women to have to bare my children unwillingly, but that doesn't mean they can't feel at least a little upset about it. After all, it's normal to rain on a picnic but that doesn't mean you ignore or enjoy it when it happens. Not that I cared, futanari have a strong instinct to breed and most of us have some sort of breeding kink. I know I did when I was young and it only got stronger after I got my powers and I got a front-row seat to watching a bunch of the girls at school, a few teachers, a lot of the MILFs in town, and my own loving mother swell with my babies.

Thinking about my sweet young niece going from fit teen cheerleader to single mother was enough to drive me to thrust deep once more and fire off a second round. I caught my breath and pulled out of her now sloppy pussy before sitting on the bed and stretching. After a moment I gave her tit a light slap, drawing a sharp yelp from her.

"Come on," I told her before standing and pulling her to her feet. "We gotta shower before the guests show up. Plus I sort of have to pee."

Sara just shot me a look of resignation before I pulled her out of the bedroom and into the hall.
