My girlfriend was playing with my balls and she was amazed that they weren't perfect spheres but more like eggs. Then she tried to switch em around (left to right witch kinda scared me) and lost her shit. I took the opportunity to show her all the amazing penis and ball maneuvers I could think of like stretching ball skin apart to make it flat. She was in awe of how much fun it seemed and said she was jealous. I'm guessing this is just something new to them? She showed me the fabled labia clap but that was all she really had
