First to wake

When you wake up the first thing you note is that the effects of Amanda's cum seems to have lessened greatly. You don't feel the urge to suck on the cock for hours on end but you do feel that if she asked or even suggested it you would already be on your knees. The next thing you note is that Amanda is still asleep her hips thrusting in her sleep using your thighs as stimulation. The final thing you notice is that your nuts hurt from being poked all night long.

You get up easily but when see her trying to thrust the air but then stop you can't help but think 'Why not just a bit' then you shake your head to stop your mind from wandering. If you sucked on it 'just a bit' you would be stuck in bed all day. You shake your head again as you notice your mind started to think about what would happen. You stop looking at the source of this problem and towards your drawers which have been completely cleaned of cum.

You pick out a simple t-shirt and baggy shorts. You try to quietly leave the room but when you move to the door you are startled by Ellie who opened it just before you and giving you a quick kiss walks to Amanda and starts to suck her off, you can't help but think that this is your fault when in her sleep Amanda reaches up and rests her hands on Ellie's head.

You leave them to it because you don't want to be caught up in that. You check your phone and see a message from Katie 'Saw you were asleep in a tub of cum when I left so I left without goodbyes, sorry. Your sister was lots of fun but wow her spunk is potent. I had to go to the lab to get something for it luckily it worked out just fine' Well at least she escaped, more importantly they had something to counter it? You send her a quick text asking her if she could get you one as well. But your hopes are dashed when an immediate reply is sent 'Sorry doesn't work on guys, or girls for that matter'

It took you this long but you realize that no one in the lab is actually trying to find a cure for the condition. One part of it to increase the population of their fuck pets, you don't recall there ever being any males born. Another part to study the effects of the cum so they can get benefits from it, then refining them into more potent versions. Then the last part the management part that just made sure everyone with the condition was satisfied, usually by giving them a girl if they wanted one. All the while they manage to get funding from the government for research into a 'Cure', you've no doubt once the government decided that it was too much of a waste and cut funding they'd just start to sell some of the bottles of various sexual enhancements.

You sit down on the couch at that revelation. They could make a counter for the effects of the cum for you but because it was a futa who did that to you they wouldn't because it didn't benefit 'One of them'. You remember that everyone in the lab is a futa or a fuck pet of one. Speaking of fuck pets Stacy walks into the room and sits next to you giving you a happy hug. She is a bit confused at your attitude "You alright? You are being weird today and I haven't even known you that long"

You are too fed up with everything to say anything complicated so you just tell her the truth "It's my sister" You pause and specify "Not you the other one, or more specifically her cum, I am under the effects but there isn't a way for me to get my hands on something to cure the effects" you let out a deep sigh as you lean back into the couch and stare at the ceiling where if you focus you can make out the quiet noise of Ellie moaning as Amanda fucks her good.

Stacy gives you another hug this time a comforting one "Oh don't worry I got plenty of my sisters in the lab still, I'll see if I can't get them to source something for you" that might work they'd much more easily listen to their fuck pets. That's when you remember your first interactions with Jen she didn't know your Girlfriend was sleeping with your mom she was probably trying to get at her until she found out she was taken. Stacy shakes you a bit "You sure you're going to be fine? You kind of spaced out there..."

"I'll be fine" You say but you don't move and just continue to stare at the ceiling.

Stacy leaves with a worried look on her face with glances at you a few times before she leaves upstairs again.

The only one who was not just hoping to gain something for themselves was Katie but in the end you ended up giving the closest thing you had to a daughter to her as a fuck pet. Ellie seems to have forgiven you for that rather quickly which you are glad for.

Your mom comes downstairs and heads into the kitchen she ignores you, the thought of where Stacy is crosses your mind but your thoughts are swept away again as you continue to think about how different life would have been if you didn't give her to Katie your mom would eventually find a way to fuck her, she'd probably do it secretly at first but then she'd be doing her in the living room while you watched.

Then Amanda heads into the bathroom to shower and you wonder where Ellie is. That is answered when both Ellie and Stacy walk down the stairs together. Stacy has a frustrated look on her face when Ellie turns into the bathroom to join Amanda. Stacy sits back down on the couch

She says to you while she leans her head next to yours on the back of the couch "Well I tried to get mom to come cheer you up but she isn't really in a condition to help right now. Good news though number five has been working as an assistant in the lab so she looked it up and found the recipe to get rid of the effects of Amanda's cum that will work on you" she smiles at you when you look at her with that news "They are planning this whole heist deal where they distract the workers and quickly whip up a batch for you" You know that all these recipes require the cum of the right person to work so the distracting probably plays two roles here.

But still you can only think of one thing "You call each other by your numbers?" she did just casually call her sister number five.

She gets a bit embarrassed and says "Not all of us mainly just the larger numbers. Like none of them call me Number Two because it sounds like I am an evil henchmen or side kick. Same with number one, and number three, number four just sounds weird though so it really starts at 5 and goes up." She laughs at that and it does cheer you up quite a bit you let out a few chuckles yourself.

You almost asked her why she didn't ask your mom for help but realized the way she cheers people up is by dicking them down but you tear your mind away from continuing those thoughts.

Seeing that you are cheered up for the time being she turns on the TV and you join the watching. at least your sisters are looking out for you despite not actually knowing you directly.

(A/N: Ending this branch here I feel this is a decent conclusion without doing a time skip. Also this has moved beyond the scope of this story of your mom and your Girlfriend. I am interested in doing another story with either the MC or someone close to the MC that has the addictive cum trait.)
