Is it normal for your cousin to rub and take naps on you

my dad and uncle are really close . so me and my cousin hangout a lot.but some times i find her on my bed. when we watch movies she falls asleep on my shoulder or no my lap she's always making me
(accidentally) making me touch her boobs and every time she hugs me
she rubs her boobs on me.this one time she put her head on my lap when i had a boner and said she loves me
