I just had sex with my step sister?

so a few months ago my dad remarried with this lady who has a daughter thats my age, 18. my dad and his new wife have been living together for almost about year and since they got married I've been spending more time with my dad. since I've been living with my dad for a few months now i really got to know my step sister. she's always been really flirty with me since we met. so anyways a few days ago my dads cousins came to visit him and they were going to stay at his place for about a week, they needed a room to stay in so my step sister offered them her room and my dad decided she could stay in my room with me. before we went to sleep we had a pretty long conversation, we ended talking about sex. i told her I've only had sex once and she told me the same. she kept telling me how she wanted a fuck buddy. in the morning i woke up to her touching my morning wood saying "having a nice dream" then waking out the room. later that night i was in my room watching a movie and she had just gotten out the shower. my dad and step mom were downstairs with my cousins having a good time, playing board games and drinking. my step sister sat down next to me and told me she was sorry she touched my boner, she told me the reason she did it was because she hasn't had sex in a while and its driving her crazy. she put her had on my lap and said "i just need someone i can have sex with". i was surprised but before i could say anything she leaned in and started kissing me. we both started to touch and grap eachother. taking off clothes. and before i knew it i was having sex with my step sister, it all happend so fast i couldnt think straight. she started moaning but because of the little party going on downstairs they didn't hear her. i ended up cumming inside her, i freaked out but she told me she was on the pill. after that we talked and she told me she wanted to keep this sex thing going. i dont know how i feel about this. i feel that its bad but also want to have sex with her. is this bad?
