Telephone addiction

My stepsister was so keen on her phone that I decided to use her, I started caressing her pussy first through her pink leggings, when I realized that she wasn't reacting, I started taking off her clothes and inserting my fingers into her wet pussy, then I couldn't help myself and shoved my dick into her and accidentally finished inside her pussy, she just silently put on her clothes and got carried away with the phone, she didn't even yell at me
