That couple agreed to participate in this experiment after the scientist in charge convinced them based on the premise of seeing themselves naked on the internet with many perverts’ comments. It seems that one of them likes to exhibit themselves and enjoys being the center of attention when it comes to sex. The couple positions themselves on the white furniture, and the scientist records them, detailing every movement of the female on her man. As they become more aroused and undressed naturally, a choreography begins at the start of their sexual encounter. Once they are both fully naked and very aroused, they exchange passionate mutual kisses and the action begins. With the bitch on all fours, we can hear how her ass slaps non-stop while the man continues to deeply penetrate her. The bitch can only stop to swallow his dick completely, and this is when we understand that they are not a normal couple.
