Parcel Mistress delivers the wrong package

She had a job to do, a odd a bizarre one, but a job nonetheless. And if there was one thing the Parcel Mistress never failed, it was whatever task she had been assigned. No mission, no goal, no objective was too much for her! As the sacred creed she sworn to uphold said, "Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds." And as whatever god was her witness, she would ride this young human boy's dick raw.

And so the grey draped exile set off on her task. Utterly certain of her success. She trekked through mountains, passed through seas, and somehow even navigated through the very chaotic realm of the Horrorterros; the furthest ring.

Through her journey she had undergone many changes, both of mind and body. Chief of among them was the addition of her canine features, such as her rather massive dog dick and knot. Whenever aroused it would grow to utterly absurd proportions. The shaft as long as her arm and twice as thick, the knot bigger then her fist. She pitied the poor creature that would receive such a monster genitalia, yet no matter her feelings, she would accomplish her goal.

And so at long last the Peregrine Mendicant found her recipient at last. He was among a group of eight, dressed in various shades of red, and utterly ignorant of his soon to be delivered package. As she looked upon him, her gargantuan dog dick began to rise with arousal. And without warning she raced to him, spearing his fine ass cheeks and destroying his pants in the process.

She pinned him to the ground, keeping her one good arm against the back of his neck while slamming her massive member in and out. He grunted as she pounded him, his own cock stiffening as she slide against all the right places. Soon she then remembered her space powers and then proceeded to increase her own size until her entire girth was equal to her knot. She continued her one woman dog assault on Dave Strider's asshole, eventually causing his dick to erupt with a torrent of cum, coating the inside of his already tattered pants with his semen.

With her mission complete she slowly pulled herself free and after getting Dave to sign her papers, went off to parts unknown. Sadly it was then that Jade finally remembered that the Postage Mistress was actually meant to give her the package instead. And worst of all with the entire Prospitan mail service now totally destroyed, she'd never be able to get a refund.
