A very normal day

The next morning you wake up nothing had changed there was even the ever present rhythm of your mom's bed banging against the wall. You pick up your device and you see that yes your mom is still going at it, but more importantly there is a message from Jen 'I left you a little something in your pants should be a better fit for your situation than my previous gift, your mom thought it was a great idea'

You search your pockets but you can't find anything one of the twins must have taken it not knowing what it is. The banging against the wall has stopped. Looking back at the video you note that one doesn't have any cum in them at all and the other is full of it. You hear your mom then leave her room and you realize that it is time for breakfast. So you quickly put the device in your pocket and head downstairs for breakfast. When you enter the kitchen everyone is clothed for once, although that didn't mean they were decent your mom was wearing a short skirt that her soft cock was hanging below not even trying to hide how it was wet and covered in cum. The twins were wearing the skirts that didn't cover anything letting you see that one had cum leaking from their pussy and down their leg. Breakfast was served quickly and eaten just as fast Ellie gave you a hug and whispered in your ear once everyone was finished "Lets get started I'll be upstairs waiting" and she leaves before you.

Your mom just smiled at you and waved you away with a strange look in her eyes you don't understand. when you leave Carol follows you, when you try to question her when she also tries to follow you upstairs she just says "I'm going to help of course" as if that explains everything.

When you walk into the room Ellie is naked laying on her back on your bed, when she sees you she lifts her legs up and spreads them wide. Then Carol walks past you shedding her clothes very quickly as she sits on her face while Ellie happily licks up the cum from there

You feel incredibly hard at the situation and you shed your clothes quickly turning around to place them in the closet and realize that you have a black ring around your hard penis. This must be the gift Jen was talking about, you've no idea what it does. You must have taken a while because Carol speaks up "What's taking you so long get over here already she's ready" and when she sees the ring you have her expression changes "Don't forget to do that special thing with your device" she says.

Realizing that you haven't activated it you pick up the device, selecting the one without cum in them, click the button once it changes from 'ACTIVE' to 'INACTIVE' you remember what Jen said yesterday about double tapping the button to increase chances so you do just that and it changes to 'HEAT' in bright red letters and a countdown with the number 3 in it.

The effect on Ellie was phenomenal as her pussy is now leaking her own juices and is opening and closing as if asking for you. She starts moaning in need and asking for it "Please~ Put it in~ Mhnn~" she lifts her hips up as you approach allowing you to easily enter her and she is incredibly warm almost hot to your dick. Strangely the ring doesn't seem to affect what you feel as you can't tell it's there at all.

Ellie stops moaning once you enter her and just moves to eating the cum out of her sister again. A few minutes later Carol gets off her and says "See ya later! I'll go take care of your mom" Once she is gone Ellie grabs one of your arms and pulls you down kissing you letting you taste what she has been eating the entire time as her tongue explores your mouth while you respond to it.

Her legs are wrapped around you they are pulling you in with each thrust into her. Must be the effect of yesterday because you last much longer than ever before. When you feel the first tingles indicating you are about to cum you push in as deep as you can, but when you do cum it feels like someone squeezes your dick and you feel the burning pressure build.

You try to pull out of her to get a look at what is going on but Ellie is humming lightly at each twitch of your dick that isn't letting out any cum. When your dick finished trying to spurt out cum Ellie lets you go and you slide out of her with your dick trying once again a few more times to get cum out. You look at your incredibly sensitive dick and see the ring is lit up now with '20%' on the top

Ellie looks at it and tells you "Oh that is a cock ring that prevents cum from leaving until there is enough cum to shoot out" when you ask how much is enough she just says "Well five times more than what you just tried to put out" she winks at you and continues "You must really want to impregnate me, making sure to deposite all that cum at once instead of in little bits during the day"

She looks at the time and says "Lets go get something to eat it's lunchtime already"
