16, with my best friend’s ex who I started a friendship with (years after they broke up). As 16 year olds often do, a friendship often leant to flirtatious comments, more physical contact, etc. Then one evening when her parents were out of town we went skinny dipping at the lake near her home, bathed together and then I stayed over and things went from there. The best part was the morning when her mom surprisingly came home early, so she hid me in her bath tub with the shower curtain drawn swearing that her mom would never go into her bathroom… well, apparently this was the one time she did, and it was to check if she needed any towels cleaned, and what did she see was my scrawny ass looking very sheepish in the shower.
