My boyfriend and I said “s” in the bathtub

(1)In the past, I played “S-S” in the bathtub
(2)We were taking a bath and got the feeling(Laughing)While my boyfriend was doing it, he poured water on my back in case I was cold(Laughing)While doing it, he poured warm water on his back several times and it was so funny. Does that really come to mind in the meantime?
