I have slept with this girl a couple times now. The other night at her apartment I had gone into her nightstand and saw a few Mangum XLs in there. It appears she is okay with my cock, although when fucking missionary she puts her hands on my ass and pulls me towards her, as trying to get me in deeper. Her ex obviously filled up a Magnum XL (whom she broke up with like a week ago - im a rebound which is okay - she is hot). How big do you need to be to fill one up? And how does that compare to by size of 5.5 x 5.5 (see profile pics)?? This is a serious inquiry.
