vibrator while using the helix

INSANE…i have only used this toy while jerkin off and the first was kinda weird the second i shot alot with it in and the third i used a massger and put it right behind the handle while layin on my back this intensified the stimulation ten fold and my leg started to get the "shakes" a little and i had some involuntary contractions…it felt so good i couldnt hold back i had to nut and i streamed all over shooting above my head and onto the head board…i tend to just dribble cum out when i nut but this was insae and i shot baout 8 times to
gunna see how far i can go with it wish me luck
