Застосовуючи секс-іграшку з моєю зведеною сестрою Сереною

my stepsister is alone in her room and our stepparents are watching movies in their room, so I go to say hello to my stepsister who tells me that she wants to use a new toy with me to make no noise when she fucks so I put it in her mouth to fuck behind our stepparents' backs.
