"Watermelon Fucker"
Close your eyes and just listen to the audio. Sounds like a 400 pound woman's gaping vadge being pummeled by cock right? I suppose 1st hand experience is required to really know the sound but the point is - watermelon's are capable of providing multisensory satisfaction, whereas most conventional sex aids lack the sound effect component. So next time you're feeling desperate, skip the adult store and head to the market - produce aisle. I recommend seedless.
