Too far

It’s then that her eyes widened, as her grandfather moves his hands to her butt, and dug his large fingernails into her cheeks.

Julia: Nohohoho wahahait!!!

Grandfather: aren’t you a ticklish little girl~ yes you are~

His fingers dig into her butt crack, and drills into her butthole, causing Julie to yelp.

Grandfather: that must be extra sensitive then!

They stay there for a moment, letting Julie soak in her sensitive she was back there. But then, he pulls away and quickly start scribbling his nails across her small breasts.

Juliana: nahahat thehehehere!!!

Grandfather: these are so fun to tickle. How about…

He starts ticking her nipples.

Juliana: Nahahahahaha!!!!!

Grandfather: they are!

Her nipples keep getting tickled.
