Mooing when I peg him

My bound bent over chattel has no idea what i'm about to do with him. he can't see the beautiful leather outfit i'm wearing, or the big strap-on cock i'm stroking with my leather-gloved hand. no worries, he will feel it inside him pretty soon. but first i will hang some nipple clamps with little buckets to his sensitive nipples, that will rattle and pull his nipples with my every thrust. in this position, my chattel's man-pussy is at the perfect height for me to fuck as hard as i want; all he needs to do is moo for me, like a little cow.
