After Hermione sees the man she loves (Ron) having intercourse with her Sexy Milf Mrs.Granger, Hermione races off vowing to give Ron "A Milf!".
Mrs.Granger says she will go check on her, and throws on a sexy robe.
Hermione heads upstairs to the attic.
In the furthest back part under some boxes and junk she finds a trunk she's visited before.
She opens the chest and pulls out many strange things until finally she says "Here it is!".
Hermione pulls out an old book (the Magic Book from Seregas other games), Hermione turns the pages until she says "This is the spell!".
Hermione stands and says the words "Incantus Milfus-Maximus!",
And in a poof of gold smoke we see her body start to grow, tits and ass become huge, she grows taller, basically as Milfy as her mom, as her clothes stretch to the max, until they're barely covering her.
(Replay option please.)
Mrs.Granger comes in after the change and finds her sexy daughters new body extremely attractive.
She goes over to her until they're standing tits to tits, and tries to apologize, saying "I don't know what came over me, I needed some dick and the boys only wanted to help, its not their faults.".
Hermiones trying to think but shes so horny from the transformation she just begs her mom saying "Please touch and squeeze my new body! Its so tingly!"
[Sex Scene 1]
Mrs.Granger squeezes her daughters Big tits (in shirt) while she kisses her neck, bar builds.
Mrs.Granger rips Hermiones shirt open so breasts pop out, Mrs.Granger kisses them, bar fills.
Mrs.Granger gets on her knees and kisses Hermione around her navel or clit, as she squeezes Hermiones huge tits or ass.
[Sex Scene 2]
Hermione gets down on all fours and we see her from behind as her Milf has Hermiones panties pulled aside and is licking her pussy/ass, then fingers pussy, then fingers pussy and ass at the same time, until Hermione cums all over her moms hand.
(Maybe an option to have Mrs.Granger spank Hermiones big ass.)
Suddenly we hear a cracking sound, the ladies then look down as the floor breaks and they fall through to the room below, where The Twins are Jerking off to MnF games.
The ladies have passed out from the fall.
We then see a scene of Ginny Weasley in her room studying until she hears the crash above her room, we see her thought bubbles "What was that?!".
It then goes back to the room where the drooling twins are standing over the passed out Milfy Granger women.
[Mini-game/Sex Scene 3]
The twins can't help but go over and fuck the Grangers exposed breasts.
They must fuck the ladies tits without waking them up, until they cum huge loads.
[Mini-Game/Sex Scene 4]
The boys decide the tits are good but now they wanna try the mouths, they shove their dicks in the ladies mouths.
The ladies wake up, big eyed, with dicks in their mouths, they don't mind
Ginny shows up unbeknownst to her brothers and starts watching from the door, peeking game like Hermiones Milf 1.
The Granger Gals now suck the boys dicks with different speeds Slow/Normal/Cock Crazy.
Ginny must watch without her brothers catching her.
After the boys cum, Ginny looks down and finds the Magic Book on the ground, still turned to the Milfus-Maximus spell, she picks it up and runs off.
