Brother saves Sister's life

[HeyAll]

The sister can be older or younger than the brother.

She needs a new (insert whatever) but her blood type is rare and donations are hard to come by. Naturally, the brother is a perfect match. Maybe they could be twins. He agrees, they both have surgery, and all is well.

Fast forward six months later.

The sister is the healthiest she's ever been. She's never been happier. She sees her brother in a new way, and appreciates the sacrifice he's made for her.

She does little things to show her appreciate, like making him baked treats, helping with his chores, ect...

The brother is suspicious and she admits it was because of the surgery. He says don't worry about it, that's what siblings are for.

The brother has a tough break-up with his girlfriend and the sister offers to fill the void in his life. She offers her body, and the brother feels awkward about it, but the sister feels obligated. Nothing smutty. More on the romantic side.

Thoughts? Ideas? Takers?

I like it. But I'd make it smutty. Yes, definitely smutty.

Bonus points if you could work the transplantation into the sex somehow. Like if he had donated a section of his colon to replace cancerous tissue in her vagina. Then when he fucks her, he'd actually be butt-fucking himself!

That doesn't seem particularly erotic but is kind of funny.

many stories here already of sisters thanking brothers erotically for much lesser things....does it need to be something medical to work for you??
