It's not quite an either/or thing for me..
A good punt can be had with mediocre kissing but enthusiastic sex and OWO with a hot girl, and a bad punt can be had with enthusiastic sensual kissing but disappointing unenthusiastic sex. But a good punt can also be had with with covered oral but good quality DFK and enthusiastic sex.
So, I guess really, the more significant factor to me is that the sex is enthusiastic. That's what I'm there for at the end of the day; a good fuck.
All that being said though, for me, the best fucks, the exceptional experiences, are ones that have good enthusiastic sensual DFK, OWO and sex.
