You are the 100th person to be cursed by the Saeki house, Kayako gives you a choice
>She lets you go and you live free as long as you never return to the house.
Or
>She sucks your dick and gives you the best ghostly head imaginable, but there's a 50% chance at the end that she'll bite down as hard as she can when she does and if she does she kills you.

What's your choice? Think carefully....
