I really love to feel the stretch when I am using a toy but I also love the deep feeling but I can't seem to go as deep as I want that's why I want someone to help train me to take things deeper. So I usually just stick to thicker toys or my inflatable plugs I don't like when I am dirty inside when I play so I usually only put toys in my butt when i am super clean after an enema and shower or during.
HKJ is not alone in her ability to penetrate deep, I advise you to watch the video from NikkiHotX, she inserts her hand up to her elbow and at the same time there is a video of her own fist walking inside her stomach, and she also inserts deep toys into herselfhttps://ru.xhamster.com/videos/extreme-anal-fuck-xh5Ov5e
I would say both long and thick my fav is the long ones with a thick knot are thick ribs on them love the feel of those ribs and knots when they pop in for a good full feeling so far my limit is around 4 to 4.5 inches thick and about 13 to 14 inches long
I must say both Laura and I prefer long. Neither of us is into stretching either our vag or our rectum But we enjoy reaching deep into both places.
