When a young male finishes in his hand and uses his splooge to fill all the wrinkles on a GILF's face.
Bjorn was adventurous in the tile industry and became bored one day during his lunch break. He went to his friend Nemo's house where his grandmother was sleeping and decided to play with himself. Bjorn finished in his hand and found himself (grouting) Nemo's GILF of a grandmother while she was sleeping.
