Again, I am unworthy! ;) This is absolutely delicious. I love Wendy's firm ones and that sweet bottom, both delightfully squishy against the floor and Mabel's attentive hand. Mabel is downright fantastic as she lets out a hot breath (I can almost hear…), looks with those half-lidded eyes, and shares a strand of drool. Dipper at his limit, eyes all scrunched up, is awesome. Better keep them closed though because seeing how fine his sister's butt is would make him shoot off too soon. :)
