I tried using the COLT Megatron Anal Vibrator with plenty of anal lube. Whether due to my major op or the fact I have a tight ass it only nestled in my ass. However, all was not lost as it has such powerful vibrations. My nipples were rock hard, as was my erection. With a bit more playing and a lot of lube I'm sure I'll enjoy the full benefits of this anal vibrator.
After a few minutes I started to pump slowly and could feel the latex bulb expanding. I kept going til it started to become uncomfortable and then let it rest. The pump has a press-button to deflate the bulb, this one was good enough not to allow the air to slowly leak out, causing premature deflation!
