Practice off the rails

Making your way upstairs as you are passing the door to your mom's room it opens and Ellie pulls you in explaining that she is going to show you some stuff about eating pussy. "Your mom said she's going to sleep, that between your sister and then me today, she's exhausted. so she gave me permission to teach you today" she sits you down on the bed by your mom's feet as Ellie crawls on all fours up in between her legs.

Looking at her pussy you see it is full of cum, and leaking it lightly. she reaches out lifting up your mothers sack exposing your mothers pussy. Unlike your Girlfriends or your sisters it looks very mature. Must like your sisters the lips are naturally off to either side forming two bumps, unlike her though you see that instead of everything tight together as if trying to protect itself its very open, her clit is poking out the top, the pedals are opened wide, and her entrance is open, but the flesh inside is closed tight.

She explains the steps to you, where to start and how to respond to the actions and movements of the person. She says watch and then shoves her face into it. you know of the affect of her juices but she doesn't seem to mind and just goes at it. you can tell it is effecting her though as her own juices are starting to flow.

Your mom reacts a bit by having one hand squeeze her breasts and the other slide down and touch her cock. Ellie changes the pattern then, every time your mom reacts to it she switches to a different movement. eventually you say to yourself "I wonder what she would look like if we stuffed her pussy full of her cum for a change"

even though you spoke softly Ellie heard you and said "you know now I wonder about that too" she takes a moment to think "Go grab a bucket" guess the lesson was over, she was now kneeling over her cock while you left to get a bucket

You found one eventually and your Girlfriend waved you over "Hurry she's close" and placing the bucket next to your mom's waist Ellie angles the cock into the bucket. she lowers herself down and starts to work on the sack which quickly causes the cum to arrive in the bucket, she didn't stop though the cum over flowed the bucket, you realize your mom could probably continuously cum if she wanted to.

Ellie uses her mouth to get the cum into your mom's pussy using fingers to keep it open, you watch as this happens your Girlfriends face is now completely covered in cum as she is having to go lower and lower into the bucket

Quickly though there is room for no more so she picks up the bucket and pours some over the surface and rubs it in, with the little that is left she hesitates a bit deciding what to do with it. as an afterthought she just pours it over the cock and balls, making sure to rub it in.

Looking at you Ellie shoves you out of the room telling you to go to bed.

In your room looking through the hole you see your girlfriend milking the cock for cum and then using that rubs it all over your mom deciding to just sleep as you are very tired.
