HUNTC-253 "I didn't want to see my brother like that! If you had asked me, I would have let you do it..." My serious step sister and my slutty play...

It's been a year since I started living with my new step-sister. To be honest, she's super cute and I really want to have sex with her! But even though we're not related by blood, she's still my sister... What can I do with this undirected sexual desire... there's no way there's a girl who can suck it all up so conveniently... but there is! There is! My childhood friend is a slut! If I get aroused by my step-sister, I feel so refreshed by my childhood friend! While I was holding back from having sex with my sister like that, what a surprise! It seems she likes me too, and doesn't like the fact that my childhood friend is always so familiar with me, so she's started to feel quite competitive...
