Fuck! Reminds me of one session with my wife when I power thrusted from under (usually I make her to set the rhythm when she is on top). That day, something came over me (I was really horny) and I started power thrusting from under after she was grinding for some time. I continued almost in the same manner shown in this video until she collapsed on top of me breathing heavily and she told in my ears “Wow, that was… amazing”.
My cock is smaller though
