We have experienced this over time now and now more and more frequently. It started with her killing her orgasms with womanizer toys and didnt dare to let her self lose, because she felt she had to pie, even she just did before we started. After a few times I asked her to let go when she experienced she had to pie. And one day she squirted, and then a few months later and now once or twice a week.
It takes a good build up, fantasy, no big cock, just let her go with the feeling, but yesterday we managed the ultimate orgasm for her. We had a long play with a stranger in a dark room while me the husband was not there, and in the middle of the act, I came back. He was pounding her good, came and then let me take over, while he sit next to her and she holding his cock, she pushed me down on her when she was about to come and hold my head tight while I was licking her, an she exploded, filled my mouth 3 times and just wet the protection beed sheet completely. She was shivering and laughing out loud and pulled me up on her kissing me so patiently and willingly, before she took my cock in her hand and let me in
Today, she is just a big smile all morning and did let me know what I can expect tonight.
Seems she need to load up for the next, and she very rarely manage two days in a row after a big shoot as she calls it.
