Thank you for such a great product! The Blue Balls has really spice up my 20 year marriage and we are enjoying it more and more with every use.

I am really not the type of person that will sit down and write a testimonial or give any kind of feedback on a purchase. After last weekend I could not help myself! I received the Blue Balls for Christmas from my husband of 4 years. To be honest I originally thought this was the lamest gift I ever received but then it happened. Last weekend we used the machine for the second time. I was doggie style sucking my husbands cock and the Blue Balls was pounding away with my favorite 8” UR3 dildo. I was really getting wet and really giving him a great blow job when he kind of raised my head to stop. He walked around and caressed my back while the Blue Balls was giving me the fucking of my life. I felt a little tickle on my ass hole…….. I was thinking to myself “please fuck me in my ass” but was afraid to ask. After a bit of caressing I felt a finger sliding into my ass and began to get so excited and wet. I am generally very timid in bed and not very vocal but I could not control myself and yelled out “fuck me in my ass”. It only took a half a second and I felt his throbbing cock entering me. I now had the Blue Balls pounding away at my pussy and his throbbing cock in my ass. He began to move at the same rhythm as the machine. The feeling was like nothing I felt before! Shortly after I could feel him begin to pump his warm load into my ass and I began to have the most powerful orgasm I ever had. I really just wanted to thank you for the Best Christmas present ever! I can't wait for my next double penetration experience with the Blue Balls!
