cheat and shrink my stepbrother for fuck him

Description: I came home because i had bought something, but my stepbrother didn't know what it was for, so i told him if he could try it on him, it was to make him stronger... he said yes. so i hit him with lightning, and he started to shrink, he didn't know what was happening, so when he got to the floor because of how tiny he was, i told him to trick him, that it was something i bought on the black pages of the internet... i just wanted to fuck him because he had a lot of dislike for her, i threatened him not to tell our fathers because he would stay like that forever... i started to undress, and do many more things
