18 year old stepsister masturbates her clitoris to feel tickles in her vagina and have a nice experience

My stepsister just turned 18 and wants to start trying out sex experiences with a dildo I gave her for her birthday. She starts putting the dildo on her clit and gets aroused quickly. She moans like a slut and then starts performing sex positions to better accommodate the feeling of having real sex. My stepsister is starting to gain experience in sex for the first time. She is turning into a slut.
