Spike loved bathing with his big sister, Twilight. As they had a private pool of heated water in which to bathe from, they would bathe together. They washed and played with each other, and it was one of the few places they could love each other in privacy. The two had a very open relationship, nudity and lovemaking were no issue to them whatsoever, and they were always finding new ways of pleasuring one another.

The young dragon latched onto one of her large breasts and suckled on the teat, pinching his sharp teeth on the areola. Twilight wasn't a mother and as such did not dispense milk, but that didn't stop the dragon from playing with those large, sensitive nipples. She put a hand to his head, panting words of encouragement to him. Before long she would pull him under the surface, allowing them to continue underwater. She absolutely adored the little dragon, and would honestly do anything to make him happy, even bringing in someone like Rarity or Twilight's mother to join in the fun of Spike's breastfeeding.

"Spike... haaah I love you..."
