>imagine the smell: heavy, musky, earthy, with a hint of hay
>imagine fondling those heavy balls, feels like oranges in a pouch made of velvet
>imagine fighting his pucker for entry, before his hole yields and allows your lubed up hand and arm to enter his backside
>imagine groping his insides until you feel that lump of his prostate at the bottom of his colon
>imagine him shuddering and neighing when you massage it
>imagine his heavy nuts churning in your other hand, preparing to eject their load
>imagine his massive rump pressing back against you, forcing more of your forearm into it
>imagine patting his rump reassuringly, then gripping the sturdy base of his tail to keep him still
>imagine working his prostate with your whole strenght until he shudders heavily, clenching down on your arm and lifting up his balls, indicating his climax
>imagine hearing and smelling his massive load hitting the ground beneath him as he pumps out litres of cum
>imagine him slowly withdrawing until your hand pops free, then turning around and gently nudging you with his large head, thanking you for making him feel so good
>imagine selling his semen for a huge profit
