It has been more than 20 years since the quiet ending of the Final War, and the beginning of the New Peace. Humanity is slowly restoring the battered Earth back to normal, and the war machines that were once used to destroy each other in a mad arms race are now being put to more sensible use...
A few days ago, you had won a raffle contest, earning the prize of having two Final War-era machines delivered to your home to act as security. As you sit on the porch of your house this morning, the transport truck finally arrives and stops right in front of you, allowing the two machines to step off, before it drives away.
First is a Guttergirl, known as perhaps the first type of war machine designed during the Final War. Its rusty-brown armor, large minigun arm, and giant riot shield would have made it seem imposing... if not for its feminine torso, which was built to have huge breasts with pierced nipples, and a rather chubby belly, all just fully exposed.
It is followed by a Guttertank, which historically was designed by the Germans to counter the Russians' Guttergirls. This tall machine may have angular red armor which makes it look like a walking tank, and a rocket launcher for an arm, but its fully exposed lower body has some very plump thighs and an almost comedically oversized and rear end, which serves to make it look no less bizarre than the Guttergirl.
But, as you watch in confusion, the two machines decide to have a little spat. The Guttergirl makes a low, vaguely groan-like noise, and rears its large shield back, before slamming it against the Guttertank's rear, making it clap and jiggle from the impact. The Guttertank emits some garbled radio noises at the hit, and retaliates by using its left arm to fiercely slap the Guttergirl's breasts, making them bounce all over the place as the square metal nipple piercings jingle like chains.
