1st and above all usually I try not to compare person to person (I will try to express my self with my poor English)
It no doubt tat is not a big fucker (looks like both are novice) like some other RLC guys or he have a problem and she try to help him with no pressure remember that before the banging (as you used) she gave him BJ
About the peeps, I heard her few and silent not like Lena Nelly or others just take in account there is people around not once at N&B apartment Efim covered Anabel mouse with his hand or she took a pillow you don't heard much form most of M&S guests and even M-XL controlled her self when people around and generally any one react different the same I can say about the enjoy topic
I had a GF that never gave a peeps I thought that she don't like or enjoy sx but I knew that after good sex she expressed her enjoyment with a kiss and mostly it was a big and long one
