This is great I can’t wait to see how Pinkie handles Spike. He is likely VERY backed up. He could also end up getting some growth going as well from him feeling some want to keep having enjoyment like this. I wonder will Pinkie talk to the other girls about showing their thanks to Spike as well.
I won’t spoil it but Spike remains in this size for the remainder of the comic.
Pinkie intends on having Spike go bareback… if he accepts.
