REALLY LONG, just plain uncomfortable silences after the finisher/cumshot. I saw this one with the always lovely Rebecca Lord last year online, in her DP scene with legendary goof balls Randy Spears & Toni Tedeschi, and damn was it SO ever uncomfortable and oddly weird for me (and we the viewer are just at home, watching after all) to see her nervously giving the thumbs up after both dolts are physically drained.
Also, the scene was also sadly even more MORE un-erotic, as there scene is loaded with very bad angles (it shows a ton of man ass; urgh) and with unflattering shots.
I love Rebecca's stuff, but admitedly, all of her scene finishers are usually pretty weak. I've only seen her take facials and swallow a bit of cum (and just a wee, tiny bit) very early on in her adult career, and she always did WAY too much damn jacking the man onto her skin after that. Plus for health reasons, which I have to respect, she always insists upon condoms in her scenes, and so that's always an immdiate turn off.
