Pinecest oh yah. The best trash ship. You guys know me by now. Cowritten or roleplayed.. *grins* by my wonderful Dipper, Smilefundip on tumblr. I enjoyed it I hope you guys do too! Nsfw and all that fun stuff. Written from Dip's POV mostly.

During the hottest days of the summer, everyone in Gravity Falls is trying to keep cool. Dipper and Mabel decide shedding most of their clothes and sitting in front of an electric fan in their room is the most convenient (and lazy) way to stay cool today. However, Dipper's budding pubescence becomes a bit of a problem for the twins. Rated M: for Mabel. Pinecest, Oneshot.
