I'm not really into the big gaping 'slide my **** bottle in without touching sides' kind of open but when I'm pounding a puss from behind and I look down at the balloon knot and it's slightly open I go totally crazy....like from not even close to cumming to right their about to cum kind of crazy. I think it turns me on even more when I haven't even messed with her butthole and it opens.
Something like this is AWESOME!
