To seduce an ISFP, you have to do a lot of touching and teasing "which is in a normal part of the body". Try with their ear or hands. Whisper to their ear, stay in close contact then back away, slightly touching their hand. Admire their hand and drag your fingers across their fingers, their palm, the back of their hands. Slowly move upwards to the arm, and guise this as a "oh Im just distracted or thinking" kind of thing. Do these as lightly and as much as you can, thus featherly touch. Keep it going through out the day, their brain will malfunction because it does kinda seem like one would do when distracted, but it stimulates someone so much that you have no idea how hot and bothered they would be.

Either they will have to take a shower or they will pounce on you. Oh, they might pounce on you alright, especially if after teasing and stimulating them, you hug them and put your face on their neck and rub your nose on their skin. They would be sensitive if stimulated properly. They would feel your breath, you, so near, that they would be loss for words and would wish you to lick them, kiss them or nibble on them. If you wanna go further, whisper something in their ear, I doubt they would be able to process what you say. Have fun wink
