After a long season Dipper and Mable return to summer camp, eager to experience a variety of adventures.
Mable hopes that one of them will be to save the world again, while Dipper just wants to live new and strange situations.
After arriving at The Mistery Shack, Dipper and Mable find Soos outside, which tells them that the others will arrive a day later.
However, all this was a lie, since, when they entered, both were surprised with a welcome party, in which, among all the guests, the girls made the biggest impression on them, because they had a different appearance from the last time they had seen them.
This generates suspicion in the boys, mainly in Wendy, who feels that something strange is happening.
Being alone, Wendy mentions to Dipper that they must join their efforts to get to the bottom of this new mystery, but Dipper only has in his mind the sensual image of girls.
Wendy returns to the party leaving Dipper alone in the room, when at that moment the door opens, showing the figure of one of the girls, Pacific Northwest, who enters the room, while everyone is downstairs.
Surprised and nervous, Dipper remains motionless in bed, while Pacifica apologizes for having treated him badly the last time they met.
Dipper accepts the apology, but Pacifica takes her intentions further by undressing and being completely naked in front of him and then bending over to reveal the hidden erection behind her shorts.
In doing so, Dipper’s penis was lubricated and ready to be savored by Pacifica’s lips.
This makes Dipper’s initial resistance to Pacífica’s flirtation give way to an experience charged with penetration, orgasm and uncontrolled pleasure as a preamble to the strange events that lie ahead.
