Is it normal that i hooked up with my stepsister?
So kinda long story, we were on vacation staying at this resort house my dad and his wife were on the first floor, and me my sister and my step sister (only through marriage) were down stairs. I'm 21 my step sister is 16, we were drinking beer watching movies. My step goes and changes into her bikini and hangs out in the Jacuzzi tub. She got a little drunk, it was her first time drinking, and gets out of the tub being loud and kinda obnoxious, but after a while she goes into my room goes into my bed. I tell her go to bed, she replied I am. I said no your bed, she said we can share. After a while I caved and went into bed after her. She still being in a bikini was really turning me on, she turned kissed me and we went from there. Next day we pretended nothing happened but I keep catching her smiling at me.
