You couldn't get over how fast the sheriff was going, as she continued to suck your penis, and didn't even pay attention to the centaur who was walking over to the both of you. Just as you were getting comfortable, you see the shadow of something feral loom over you, while the stallion penis gets shoved up the sheriff's butthole.
The sheriff moaned in pain, & pleasure as if she never had anything so long shoved up her own butt, while at the same time sucking something that lost to the length competition, because horse penis was longer than human penis. As the sheriff was being penetrated both orally, and anally, you were too distracted by how much she's sucking, and didn't even see that her pussy was changing, or that teats were sprouting below it, after it shifted to a more comfortable area.
