[Please note: We can only make this toy with marbled colours, or all in one colour. Thank you.] Introducing Tsuki! As an unlikely hybrid between two species that usually don’t play well together, this toy presents not only a series of pronounced barbs but also a rather sizable knot which makes his partners squeal with delight. As a total premiere for Akifu Toys, we're proud to announce that we are able to deliver this toy to you with an inflatable knot, making sure that once it's in, it won't come out until you're ready. This candid shot (which found its way to us from a source which would prefer to remain anonymous) is a perfect example of what is commonly known as Big Dick Problems. Caught unaware by his own excitement, this normally shy and timid Hybrid is confronted with a sudden flush of arousal while experimenting with new outfits. Just as the toy it inspired, his knot isn't going to go down by itself! Measurements: Total length: 26.6cm Total usable length: 24cm Diameter of tip: 3.8cm Diameter of shaft (smallest): 4.2cm Diameter of shaft (largest): 7.7cm / 9.5cm (When Inflated)
