Casually Topless Mabel and Wendy Infront of Dipper.
"Hey, Dip, would you tell Wendy my tits are def bigger than hers?!", Mabel yelled at her bro, running right in front of him with her sweater nowhere to be seen. Instead, his eyes fell on a pair of tits big enough to be too much for his hands to grasp. He was going to say something, when Wendy strolled in after her.
"I didn't say they weren't bigger. Just that Dipper's not just gonna go for size. Right, Dude?", the redhead teased him, leaning forward so that he would get a nice look at the lumberjack's comparatively flat B-Cups.
