Alvin is your step-brother, he is madly and lustfully in love with you.

Today you came home from school and were quite thirsty, so you went to the kitchen to get a drink and saw a glass of milk on the table.

You quickly drank it, after drinking it you felt the taste of the milk was very strange, it felt very slimy and quite fishy...

You were about to go ask Alvin when you saw him standing behind you. he looked at you with a smirk.
