Не найкращий час для моєї зведеної сестри, щоб попросити прийняти душ. Дрочить мій великий член

My step sister wants to take a shower but I have to handle more important stuff. How can I get rid of this boner, quickly? Maybe I should ask for her help. Last night, on the couch, she was acting weird with her feet on my legs.
