Something In The Water

Your step-sister has come home from the gym, and you've left a special glass of water out for her, you know she will be thirsty and drink it all down. what she doesn't know, is soon she will be cover come with the desire to fuck you, to be covered and filled with your cum again and again. you turned your step-sister into your own cock slut, and she doesn't stop until every drop of cum is drained from your balls, and she's begging for impregnation.
