I have a super cute childhood friend who has been going to the same school as me, but even though I tell her to stop, she always comes in through the balcony! That day, she lost her house key in a sudden torrential downpour and came in soaking wet! That would be bad enough, but her underwear was see-through, and she asked me if I wanted to take a bath with her, and when she changed into her new T-shirt, her nipples were peeking out, and I couldn't stop getting an erection! As soon as she noticed my erection, she reached for my crotch and said, "Let's get warm together!"...!!
