Ooh, that's a good one! Lessee... I really enjoy my egg plug from Lycantasy, it stretches me just about to my current limit then feels amazingly comfortable when it finally slips in all the way. I also REALLY like their Rougaroux too. The Gryphon toy from Zetapaws has a really nice tapered shape with a girthy head - that one is my favorite to grind back on in the shower and it makes me gasp every time when the head finally pops in, huff. But I think my favorite of them all is from Rah's collection - the Caiman from Xenocat, a girthy, smooth tapered toy that I still can't get very far in me, but oh man it opens me up like no other and feels SO FUCKING GOOD <3
