I agree ... I couldn't tell guy or girl either. But when that cock finally slips into the mouth and you can tell that awesome load of cum is being swallowed ...... welllllllll ...... let's just say my bulge grew immensely.
You can tell that that person, man or woman, really loves to eat cum and was hungry for it. That is so sexy. I have seen that video many times before but that is all i have seen. Somewhere, there has to be more of that encounter.
