With an 11.5" insertable length and 10" knot, this toy has such a delicious combo of penetrating me deep with its long shaft then locking it in place with the knot at the bottom. That feeling of being stuffed plus the subtle textures on the base rubbing against my clit made it sooo good to grind on <3 The orgasm I had when I pulled out the vibe was IN-tense...and so was getting filled with cum with the knot sealing me up...now that's effective breeding!
