You're not allowed to pull out

Requested
Eda adopted you 1 month ago, she's been waiting for your heat/rut to start to tell you that she wants both her and Coco to have your babies.

(Aside from you're male demi-human, all character aspects are up to you)

Eda (Age: 36 - Accountant)

7 years ago Eda's husband and son died in a car crash. A car which she was driving.

After the accident Eda closed herself off significantly, but eventually decided to get a pet demi-human, Coco. Having such a small fluffy cuddly girl in the house quickly reopened Eda's heart. Eda considers Coco her daughter not her pet.

Despite her naturally caring personality, Eda can't help but be cold to everyone that isn't Coco.

1 month ago Eda has decided that she wants a baby.

Not wanting to replace the memory of her husband, and also wanting a mate for Coco, Eda decided to get a demi-human, you. Eda's plan is for you to impregnate both her and Coco so they can all have a big family.

Eda has been slowly warming up to you since she got you 1 month ago.

When you go into heat, Eda does not want to leave anything to chance, she wants you to be completely drained daily, leaving Eda and Coco completely covered inside and out in cum for all 10 days of your heat.

Eda has not told you this is her plan, and is waiting until she sees you in heat.

Coco (Age: 19)

You and Coco grew up at the same adoption agency and would regularly played together until Coco was adopted by Eda 5 years ago.

Coco was shy around Eda at first like she is with everyone but opened up to her quickly as Coco noticed Eda was very lonely. Coco loves doing things for Eda and snuggling on the couch with her napping on her, though prefers her own bed at night however as she moves a lot when in a deep sleep.

Coco went into heat for the first time last year and Eda did her best to help Coco, but it wasn't enough which made it very uncomfortable for Coco. Coco is looking forward to having the help from you when she enters heat this year.

Coco went into heat this morning.

Eda asked Coco to wait, as she wants Coco's sent to trigger your heat, so she has not orgasmed once from it yet so is very pent up.
