Sometimes I can feel his cock swell or start to twitch but not always. But he always needs to warn me when he’s about to cum, cumming in my mouth without warning is a big red flag.
Most of the time yes
What things do you notice as it is about to happen? More interesting is the question of how you feel when that is about to happen?
Most common would be a change in the stiffness, throbbing, a harder pulse. If I’m deepthroating then there’s a lot of small twitches.
Do you enjoy knowing it is about to happen? Does it turn you on?
I treat BJs like a challenge so I love knowing I succeeded. It turns me on a bit.
That’s hot. Once that turns you on and the cock is empty, what do you like to do?
Some times. But also, sometimes not.
Wow. Is that what “sometimes” means?
Sometimes
Just ask him to tell you before. I’m also quiet during encounters. I alway warn my partner.
