Sex-ed with stepdad

Description: I've never had a boyfriend and haven't even tried masturbating. all of my friends keep saying it feels amazing to have an orgasm, so i bought a vibrator and am about to try it for the first time. i'm nervous but excited to see how this feels. i'm immediately impressed at how good and intense the feeling is, and catch myself being a little too loud. soon, my stepdad enters my room and catches me masturbating. i'm embarrassed and afraid he'll get mad at me. however, he's very understanding and reassures me telling me it's totally normal. he's not mad at all and actually wants to help me. i figure he's definitely more experienced than i am and let him guide me... he wants me to cum for him, but how will i know if/when i'm cumming? he tells me i'll just know... surely, as my wand vibrates on my clit, i can tell i'm getting close and finally explode in an orgasm. my pussy is so wet ; i ask my stepdad if it's normal. he says it absolutely is and that's is ready now. step-daddy isn't done helping me yet. he asks if i've ever had sex and i shyly admit i'm a virgin.... he wants to teach me how to get cock... i guess that will help me be more prepared when i have a boyfriend, so i accept. as he's fucking me, he has me use my vibrator on my clit and i come again, twice. then, he tells me to ride his cock. i'm afraid i won't be good at it, but step-daddy will teach me how to. so i hop on his cock and fuck him until he nuts.thanks, step-daddy, i love you so much!
