Why don't you just use little language in a seductive way?
"Daddy, my special girl place wants to play too!"
"Daddy, can I suck on your lolli, pretty please?"
"Daddy, my nipples need kisses."
Other than that, you could do pretty much usual seductive things like rub against yourself in front of him or "accidentally" rub on his lollipop, acting very curious when it begins to react to the friction.
You could also play dress up for your Daddy...that's kind of popular and can be fun.
