Your writing is good, the excitement came from the Dom letting the sub top for a little bit. It's good when a Dom has enough confidence in a relationship to let his/her sub play a little, variety is nice as long as each remembers his/her true place.
Although, the way the story was told was confusing as to who was the Dom and who was the sub. It's difficult to figure our characters when written as "I" and "you". Perhaps using names would be easier on the reader.
