Hermione tries to convince her mother for the Threesome

Mrs Granger arrives back from holiday first, a bit annoyed at her husband.

"Hermione, love, I'm back"

Hermione bounds down the stairs and wraps her mother in big hug.

"Hi Mum!"
"Hello darling!", she said with a big smile. Seeing her daughter always brightened her mood.
"Where's Dad?"
"Fucking some slut perhaps! Did not pay any attention to me during our trip!"
"Oh Mum, that sounds awful but I think I have a way to fix that for you"
"Oh I'm all ears darling"
"Well Dad is cheating on you is he not, so why don't you get back at him"
"I'm tempted too sweetheart, but who with?"
"Well, Harry is here. You could with him"
"Hmmm that's does not sound like a bad idea. From the sound of it you know what I should expect already"
"Yes Mum, Harry and I have been sleeping together, but no worries we have been perfectly safe"
"Well alright I guess it wouldn't hurt, but there sounds like there's a catch"
"Well I did promise him a threesome with the both of us"
"Oh my, that would definitely get him going. Are you sure you want to do that Hermione? There is no going back from here and no one can find out"
"Yes Mum, I'm sure and don't worry I won't say anything and neither will Harry"
"Well alright then, I'm too worked up to even deny this opportunity"
