Rarity has established a friendly relationship with the local Diamond Dogs, both for the purposes of trade and for more personal reasons. On her latest trading trip, she gets to meet a big, friendly Diamond Dog. How big? Very. How friendly? Extremely.

Contains: interspecies sex, bossy Rarity, slobbery tongue action, big canine cock, naughty uses of magic, knotting, cervical penetration, mild cumflation, and a very satisfied, overfucked unicorn.
