Both (cumswap)

Your sister realised first what was about to happen and you both watched enough cheezy films and shows for her to try and push you out of the way... which all it did was guarantee both of you hit. As you feel your mind go to mush with this super warm feeling, you feel a thud as you land on the ground but you don't care you don't even feel pain, you just feel good.... super good.

Your mouth feeling someone grab you, and push some gooey liquid into you. It can only be one person, your sister. Not like you care, why should you... the cum feels so good and she must feel good too... shes just sharing like a good sibling why shouldnt you do the same.

You take her gift and meet her tongue, running it around her's to taste the cum more but also passing the cum for her to taste. Out of the corner of your eye you see the women has still remained, already jerking it again and walking over. "Names alexa, what's yours?" You can barely speak its too good but you can't stop your sister from pulling out. "Im jenn, this is my bro.... fuck he looks more like me than a bro.... this is my sis jack..." she says your not sure what shes on about but you dont mind and neither does she as you give a peace sign to the futanari.

"Well how about you gals keep the makeout going..." she says clearly using it as material and she seemed close already, a quick shot with how you could see her open coat was drenched in stains... your analyse couldnt last long as your sister seemed content with the plan. Adding even more enthusiasm and groping to the taste share, not minding a show.

Your mind still lagged behind as you followed her actions, though with less enthusiasm... though she didn't mind understanding your still on your cum high. Alexa definitely didnt mind, infact loving it as you see your vision in your right eye go white and you can only assume she got a double kill again as both of you moaned at the hit.

"God you two are cute.... how about you girls stick with me for a while, have a little fun as well?" She said thrusting her dick as your sister and you gave a smirk and silent approval to that plan.

You can hear down the dark main street some walking and whispering... you giggling to your creampied sister and mistress as you know for a fact that they wouldn't be trying to hide their prescene if they were seen the love as you had. As you surpress your giggle and begin your act to draw them to your fellow degenerates. Your sister prepares grabbing a bottle of your cum and her juices mixed to throw as Alexa grabs her trusty tool to make the shot.

"Gals, where are you...? This isn't funny!" You say with your sisters cheerleader outfit a perfect fit on you... especially with all the cum stains from the sex waiting around, transforming it to fit but even with its clear sluttification you know itd take a while to figure out your infection.

"Miss, are you alr-" You hear a male in his 40s say "No im not! My friends ditched me in an apocalypse! A fucking apocalypse where everything is sprouting dicks, like its cool to be what you want to but i dont want them...!" God its so hard to act mad especially with the juicy stuff stuck in your ass and stomach being so nice and good "I understand, i understand but screaming is going to their attention, so quiet down as we come over..." your mind realising who had that voice your own mother has made her way over.

Shes so caring coming to find you guys all this way and she could have easily got distracted finding you three. You can't let her get this far without a reward. "Oh your on the cheer squad, you must know my jennifer!"

"Jenn? Shes one of the people who left me at the party hmph... but yeah we were meeting up this way..." as you come up to your own mom, a little saddened that she didnt recognise you but still a little glad it just shows how much of a sexy bitch you are now.

She seems to follow you back up as the guy seems wary and realises the fishiness of the situation. The fact you were walking the opposite way originally, the weird uniform you had, the outline in your pants despite opposing dicks apparently, the brustling around like someones watching and white stuff dripping down your neck and thighs . He seems to realise as you smile and open your mouth, ready for the cum shots out the dark and bringing the family back together and a cute guy!
