It is easy for me to tell when my girl is about to cum! Her pussy tightens up so much it almost pushes me out and by the erotic expression she gets on her face. She is a squiter to so it is really easy to tell when she is done.
My girl is pretty subtle, but even I can't mis-read HOLY SHIT FUCK THAT FUCKIN PUSSY OH FUUUUUUCCCKKKKK!!! I usually get the idea.
Breathing gets heavier, and she holds her breath. I love when she holds her breath. There have been times where she's held it so long it's worried me, though. I've had to say, "Breathe, dear!" to start her up. There are few times during sex where she's not climaxing though, so really I only notice "signals" of almost cumming right when I start or if I decide to stop and then start again.
My partner pushes her head back, lifts her mound up to my face, pants, curls her toes, and rubs little circles on my arm with the pads of her fingers :love:
