Fighting for position on the starting lineup

I've got to hand it to my MGX classic, it put on one hell of a show the other night. I've had it for a number of years, but due to work and family constraints, I usually only get in a few sessions a year when I have the house to myself and can really let myself go. Over the past few months, I've been trying to make a more concerted effort to get in some prostate/anal play when I can, whether during sex with my wife or just while in the shower. The other night, I took a bath after the kids were asleep and my wife was busy on a project of her own, and brought my MGX with me. It was great relaxing in the tub and just letting things happen of their own accord, but there were no earth shattering sensations. After getting out and drying off, I left the MGX in and went over to the bed. I've been considering, and frequently fantasizing about, purchasing a Progasm in the near future. I find that I rather enjoy the feeling of fullness that larger objects provide. I bent over the edge of the bed, keeping my feet on the floor and my ass in the air (a position I've never tried with my Aneros before), and started imagining a Progasm filling me up. Almost immediately, my little MGX jumped into action. I started having involuntary contractions like never before as it literally started to assertively fuck my ass with a mind of its own. It felt like it was dancing inside of me all of its own volition and all I could do was surrender. I buried my face in the mattress and started moaning like crazy. I couldn't tell how long this went on, but it was absolutely delicious, wanton pleasure. On the one hand it had me begging for mercy, but at the same time pleading that it not stop. Towards the end, it actually drove me to my knees without my conscious knowledge. It was hands down one of my best sessions ever, and now I get hard just thinking about having a Progasm take control of me like that. I still have to hand it to my MGX though, that little guy did one hell of a number on me!
