i have had many toys in the toy box and this is the best extension i have had.. it has a real feel and look , however this is about the the biggest i have seen , it is soft like a real but firm enough to be effective , it makes you over 3" longer and is very thick , it is for size queens not the gf who is ready for 1 more inch , so if your working with a baby mamma this is great , i did not need to cut it , allows a 6-7 " ***** to fit inside and go in dry to get the rigid **** feel . guys under 6-7 " will need to cut length of sleeve but dont worry if ur 4" you will be almost eight and the thickness will max her out , best extension i have tried . unless her ***. is stretched out / ruined this toy should be used after you **** her with your own **** a bit to open her up , may wanna get some lube too , again very thick . tip warm it in warm water first so it feels real , blindfold her and surprise her !
