Man to Herm, feminine centaur

[Ordos]

Pardon if this is not the proper procedure for a request on this forum.

I'm looking for a transformation sequence I saw way, way back, before I was in the habit of saving my favorites.

I don't know where I first saw it, but it was likely one of the chans.

It starts with a cat woman and a normal, average man together in a bedroom. I don't remember text, but there might have been some in Japanese. It seems like the two are in a relationship, and the cat woman brought him a gift. I don't remember what it was, but the gift turns the man into anthropomorphic mare.

She seems shocked and stunned, but the cat girl goes to the door, and opens it to reveal an anthropomorphic stallion. The stallion approaches the new mare, who seems very shy and torn about her attraction to him. He moves around her and brings his head toward her rear, near her tail, and then proceeds to be partially absorbed by her. When its over, she's a centaur with completely feminine humanoid portions, presumably a feminine sex up front, and the stallion's very visible penis in the rear.

I saw this once a while ago, and I don't have the slightest clue where to look. If any of you happen to have saved it once, or can direct me to where I may find it or something similar, I'd be very appreciative.
