Got a little canine dildo with a knot on the base, nothing crazy like the bad dragons or anything... But I wasn't able to take the knot, I've very inexperienced with butt play... I hurt myself a little trying to ram it inside of me >.< But it made my lil useless dick nice and hard thinking of how it must feel for the children smaller than me who get ass fucked by giant pedo cocks, it must hurt so good.
