best toy I ever bought when I stuck the 8"er up my boys ass he was screaming and cumming almost imediately I found it to work quite well with the Ryobi 18 v. recrip saw really helps that theres no extension cord to deal with even with the "quick lock" system on the ryobi all holds fine even in the tightest hole havent let him use it on me yet but I'm sure I'll get woke up one night with it plowing me as well6 hard cocks up not enough try 10 hard cocks up the boy is in heaven when I use it on him
