I came here today not for work, but to have sex. A black belt in sex! A woman with an insatiable sexual appetite! A group of sex professionals gather around Riria Sakaki and make her cum over and over again! Direct hits to the G-spot! Multiple orgasms! An explosion of erotic squirting juices! Riria's onslaught of hardcore pistons that never ends, even after she cums or squirts, seems like she'll be defeated quickly, but she begs for more and more pistons! Even the professional actors are so weak that they give up! How much do you like sex? ...Hmm... about the size of the universe...
