Doing sex ed homework with a cock in Emma Hix's mouth

Day one - she's masturbating before fixing her nail polish. She is quite loud when she's massaging her clit and I could hear her from downstairs. Day two - She saw I am spying on her and told me to fuck off. Day three - she's finally sucking my dick! I knew my step sis is the real pervert but will she give me to nail her pussy?
