Kissing with sister is allowed in Islam?

No, don't even suggest it!

It is not allowed to have a lip kissing between two sisters or two brothers or a sister and brother or a father and his daughter or a mother and her son. This prohibition is per cultures and all traditions as it is against natural senses and feelings.

Per Islam religion, all kind of sex (including kissing on lips) are not allowed between two sisters, two brothers, brother and sister, father and daughter, mother and son, or any close relatives.
