Pacifica was cocky at golf, and when she played with Dipper she liked to challenge him since he never impressed her. It was during their breaks that the boy would impress her, fucking her pussy until he filled her with his thick semen. Hole in one.
On other occasions, Pacifica invited Dipper to her house, and while everyone talked in the dining room, Dipper fucked his lover in the dark hallways of the Northwest mansion. No one knew their dirty secret, but the stains of Dipper’s semen on the carpet, and his smell on Pacifica’s body were good indicators of the truth.
