I wore crotchless panties on a date and when he found out mid-foreplay his face did this thing I'm going to think about until I die I bought them specifically for this date. He didn't know. We went to dinner and I sat across from him the whole time knowing what I was wearing under my skirt and that secret energy made me bold and funny and flirty. I kept crossing and uncrossing my legs. Back at his place we were making out on his couch and his hand went up my skirt and his fingers found the opening in the lace and he FROZE. I watched his face process what he was touching and then his eyes went wide and then dark and his jaw clenched and he looked at me with this expression that was part shock and part hunger and part "are you kidding me."
