I like hearing them say how good it feels and how well I can work it. Knowing that I am pleasing my significant other the way she likes it is a plus for me, so its like I wanna hear feedback. Also, If they know how to speak another language, even better. Just something about hearing another language just spices it up. Yeah you hear the typical "fuck me baby.. harder" and all that, but when I hear it in a different language.. its makes my heart race. One of my ex's once said: "your dick feels so good hitting my walls.. fuck your hitting the back of my pussy" and "I'm fucking sweating baby.. make me sweat.. fuck make me sweat.." and "fill me up daddy.. do you want me to swallow you?" All in her language. That drove me crazy...
