fucking my unlubed hole hard with bigger and bigger dildos and bottle

Warming up my hole by fucking it hard with toys completely dry with no lube to stretch my anus and make it gape. Then increasing the size of the dildos and fucking my hole harder and harder until eventually it starts to self lube and finally I can push a wine bottle up inside me.... whole session done with no lube just my own ass juices and it gets reaaallly sloppy
