Ah yes, my gf has currently got 2 strapons, (well they're doc johnston vac-u-lock so it's really 2 different attachments she's got) one is 6" and is pretty much perfect
The other is something crazy, like 10" or something and it's thick, as much as I love her fucking me that thing won't be going in there in a hurry :D It's nice to suck though
She also has a 6" suction base dildo that I often have to suck when she's fucking me from behind with the strapon
She used to have another 6" strapon but it was really soft, like it was too soft, and we ended up losing it when she moved out her old accommodation, I guess the people who moved in after her have it now
