Tease him, text him that your sending a nude and send something else lol
something fun you are doing/ an interesting place you are at.
Swimsuit pics are always cute, you being doll'd up in a cute outfit...those never fail for me!
anything almost nude is good to send
Barefoot in a sundress holding a flower in a field if you can manage.
if you have a brother or sister, get them to take a selfie of themselves, then send it.
Guys always appreciate pictures that shows the body, or the perfectness of your figure.
Wear something that shows a little cleavage, maybe with you biting your lip and looking innocent. Or have a bra strap hanging off your shoulder while biting the tip of your index finger.
Old cartoon panels with romantic or funny scenes..! Maybe Betty Boop, Krazy Kat..
