I’m a big fan of the objectification this set-up creates. The heavy and full coverage dog suit is dehumanizing – and therefore hot – in its own right. The suspension bondage reduces agency still further. The motorized milking machine will drag a specific reaction from his body whether he likes it or not. The fact he can helplessly flail those stubby limbs around but change nothing makes for a lovely finishing touch.
The creator of this scene is Mistress Hinako and she posted this along with a short video to her Twitter feed. As she says there – ‘I wake up early every morning to milk my dog’.

If Mistress Hinako put a timer on the power socket, she could have a delicious lie-in, knowing that her dog’s milking needs were being looked after while she snoozed. But it’s not for me to give advice to a domme.

Maybe one of those crude socket timers designed for turning lights on and off when you’re away? Only gives you 30 minute increments, but that should be fine for our dangling dog!

The sight of it should help drive off any burglars too, I’d imagine.
