I've only jerked off in front of women while getting prepped for sex.
My girlfriend enjoys it. Ill do it while she goes to town on herself with her dildo, or similar to Noel. Ill eat her pussy & butthole out whie she's bent over & jack off or while she sits on my face.
She told me to jerk in front of her so that she can learn to give me good handjobs!
Of course thats always the mission! but yes I have, Ive had a few gf's ask me to do it while watching them with their toys which is awesome ! But gets hard to resist (pun intended) jumping on them. Id much rather have sex, but its a good starter or finisher depending on circumstances. Even fun during! but I also have woke up in the middle of night when GF was tired and I was rock hard, she felt it and said to just stand over here and do it.. lolRather than jerk off, I'd rather just have sex!
