A few years ago I was having a RnT session with an ML. She was laying beside me giving me the HJ. I was licking her nipples, biting her neck and fingering her; she was getting really aroused. Suddenly she just rolled over and jumped BB onto my dick, just as I was about to cum. I got her off quick smart, but probably let one squirt out.
Scared the shit out of me, but it didn't seem to faze her.
Took condoms the next time, but she had left the shop.
