isn't taboo.

Josh really couldn't resist the temptation. He got his phone out, launched the app and found the rules about family relationships. He had a few changes to make.

**** between blood related adults isn't taboo or illegal. Consanguinity causes no troubles or defects in children born through it. Love between parents or siblings of the opposite sex is the same as with a lover.

As soon as he wrote that his sister got up and came to kiss him on the lips.

"It's been a while since you came around bro. Do you have any time to take care of your little sister? " she said grabbing his crotch through his pants. Well his sister always loved him a lot already before.

"Sure, always time for my favorite girl. Give me a minute and I'm all yours." he replied. He forgot to pee before leaving his apartment and really had to go.

He went to the bathroom to relieve his bladder and didn't notice he left his phone on the coffee table with the app open nor he fact that his sister picked it up when he had his back turned.
