The usual sounding routine

This is a normal urethral training with an unexpected orgasm. Starting with number 12. We continue with 13, 14 and 14.5. The peak is 15mm, which really can't be inserted. But when she's really into it, she just tucks it in. I don't need to tell you how much pain that causes. Eventually, she's trying to see what progress this stretching has made. After the index finger, she tries the ring finger. Before she can get to anything, there's an unexpected spurt.
