Danny misses the milkings, I bet. And when he's being fingered he squirms and begs for more, desperately wanting to be empty again, he feels so overful and clumsy when he's not been milked. And when he comes and there's not enough in it (from being recently fucked) he feels seriously upset and afraid.

Do they use a prostate wand or just their fingers? If it's a wand of some kind I bet Danny drools over them in sex toy stores or online, buys his partner/s several.
