But we do not try double penetration right away. There must be some foreplay. So, this blonde babe first of all does some blowjob. This is good in order to make him rock hard. What is the next step? It is to start doing double penetration. He puts the dildo on his own dick. And this can be used to fuck her ass. With the cock, both holes will be filled. This is a good double penetration.
