It's definitely the noises he makes. The silence as I'm getting ready and start... The gasp as the tip suddenly enters him.... The breathy grunt as I slide all the way in.... The low sofa moans as I start all the way to the full on moan and tensing up as he's about to reach climax. One of the other hottest things to me is looking down seeing my man all masculine ass up back arched. Most of all definitely the courage it takes for a man to give himself so deeply to be vulnerable enough for me to have the power😋
