The girl I am seeing wanted to use a double-ended dildo on both of us. She fucked me for a bit and then left about half inside me, then we both got doggy on the bed, ass to ass. It took a little doing, but once she got the other half in her ass, we pushed together till our asses touched. I swear it felt like I had most of it in me, but from what I could see in the mirror (she has mirrored closet doors) that it was equal between us once we finished and pulled it out. I even tried to push my cock between my legs and into her pussy, but our butts were at different heights and I couldn't get in all of the way so we could actually fuck. Felt great! I am going to see if she will let me video it...
