Vega is a beast of a cock.He's got a fat swollen head and a thick veiny shaft for you to master sliding up and down on.We made Vega so he wouldn't have a sharp ridge or bump when you finally get his head in but what you will get is a very brief feeling of respite.You've got his head in your hole is full his thick shaft is still stretching you out but now it's time to try sliding up over that head again until you're bouncing on him with no resistance.SizeSmallMediumLargeXLTotal Length CM19253037Total Length IN7.489.8411.8114.57Insertable Length CM16222731Insertable Length IN6.308.6610.6312.20Circumference of Head CM13182125Circumference of Head IN5.127.098.279.84Diameter of Head CM4.145.736.687.96Diameter of Head IN1.632.262.633.13Circumference of Ridge CM16.0021.0027.0030.00Circumference of Ridge IN6.308.2710.6311.81Diameter of Ridge CM5.096.688.599.55Diameter of Ridge IN2.012.633.383.76Circumference of Middle CM15202529Circumference of Middle IN5.917.879.8411.42Diamter of Middle CM4.776.377.969.23Diameter of Middle IN1.882.513.133.63Circumference of Bottom CM15202529Circumference of Bottom IN5.917.879.8411.42Diameter of Bottom CM4.776.377.969.23Diameter of Bottom IN1.882.513.133.63Suction Cup CompatibleNoYesYesYesSuction Cup SizeN/ASmallSmallLarge
