Looking for videos where there is a pause before the guy cums. For instance the girl stops blowing him to look up and talk or something and a few seconds after the stimulation ends he starts cumming. This could also apply to cumshots during sex where the guy pulls out and then several seconds pass (with no manual stimulation) before the cumshot happens.
A variation would be the girl simply being surprised by the cumshot, as in she wasn't expecting him to cum anytime soon.
