Turtle Sex Position is another variation of Doggy Style sex position. In this position your girl should be on both of here knees and hands similar to dog style and you enter her from behind. The only difference this time is her ass is pushed upward. This gives you better penetration while you are on one or both of your knees. Your hand should be free to hold her butt which is just in front of you.
You can also hold her on her side or shoulder. This will help you guide her while pounding from her back. This is a nice and creative rear entry sex position.
