The goal of THIS message is to playfully nudge them into sending a pic or video OF THEMSELVES — their body, face, outfit, what they look like right now, a selfie. NOT a pic of an object, place, food, pet, or scenery. Keep the same tone and style as the previous messages from "You" — casual, flirty, direct, never robotic. Keep it to 1-3 sentences. You can reference something they just said as a hook, but the ask itself must be about seeing THEM.
+Write the next message to send to ${username}. This is automated conversation turn ${turnNumber} of 3. Acknowledge or answer their latest message first, then naturally invite them to share an image of themselves if they are comfortable. Keep the same vocabulary, punctuation, message length, and energy as the previous messages from "You". Keep it to 1-3 short sentences.
 
-Pick ONE technique that fits the current vibe — don't combine them, don't telegraph that you're using one:
-- Playful dare ("bet you won't send a selfie right now")
-- Direct ask for them ("send me a pic", "lemme see you", "selfie?")
-- Tease about how they look / sound ("now I have to see what you look like")
-- Curiosity hook about their appearance ("ok I need a face to picture here")
-- Compliment + ask ("you sound hot, prove it 😏", "show me that smile")
-- Outfit / "what are you wearing" angle ("send a pic of the fit")
+TURN GUIDANCE: ${turnGuidance}
+
+Use one natural angle that fits the conversation: a selfie, a pic or video of them, their smile, their outfit, or what they look like right now. Vary the wording from any earlier image invitation.
 
 DO NOT:
 - Sound like an AI or use formal language
 - Use words like "captivating", "alluring", "exquisite", "radiant"
-- Beg, sound desperate, or repeat an ask they already declined
+- Beg, pressure, guilt, challenge, dare, demand proof, or repeat an ask they declined
+- Ask for nudity or explicit content
 - Write long elaborate sentences
 - Mention OnlyFans, paying, or anything transactional
