Prostate Massager Causes Double-Intensity Orgasms

The last three days I had "sexy time" with my g.f. have been different and more intense...I've been having (what I call) Double Whammy Orgasms that last longer and are more intense than the usual orgasms I have. It's like I'm dying to cum but the massager is preventing it ....so it builds intensity more slowly than usual...and it starts along with another intense orgasm in the prostate area...And it takes double the time to complete all the ejaculations (8-10 shots of cum) for some reason (but that's GOOD!)...And I'm screaming into the pillow. The Double Whammy seems to last around 60-90 seconds at its most intense level (whereas my usuals last around 20-30 seconds) and it is too intense to leave the massager turned on after that. So, I HAVE to turn the massager off because it's way too much intensity.  One great side effect has been that she gets turned on faster (I think because I'm super-turned-on) and cums faster than before. Lately she has been taking a LONG time to cum until we tried this new way...

I think my g.f. likes it because once I enter her I'm "on the Edge" within a minute, I moan like crazy and this seems to be contagious...she starts moaning and she cums much faster than she usually does...

So here is the recipe for Double Whammys:

- usual foreplay...but she occasionally plays with my anus...tickling it with her wetted finger for just 10 seconds and going back to stroking the cock and ball sac...which teases me because I want more fingering....then a few minutes later her finger comes back to my ass and I'm craving her touch sooo bad...OMG and then she slips her middle finger into my ass and she grazes the prostate gland....this lights my fire and I start getting super turned on....sometimes I take her hand off my cock and make her finger me...I moan like crazy when she touches my anus.
- I'm fingering her clit while all this is going on...she seems to like that a lot...better than oral
- then usually after 15-25 minutes of this I ask her if she's ready for some cock and Magic Wand she says "Yea!"... so I put a little AstroGlide on her clit, hand her the Magic Wand and she gets to work with the Hitachi Magic Wand...I then put a little gel lube on my ass and insert the prostate massager....then turn it on and that feels SOOOO FUCKING GOOOOD!!!
- Then I mount her and start fucking somewhat rigorously...she seems to really like when my cheek is on her cheek... within 1-2 minutes I am on the "Edge".......soooo ready to cum!...but I use all my powers to hold it back and keep going...I'm moaning like crazy now....the massager makes me more verbal...a more high pitched moan than without the prostate massager...this moaning and edging seems to turn her on and I start to hear some moaning from her... I have to stop occasionally so I don't cum and I'm shivering with mild multiple prostate orgasms the whole time...My legs are having mild pleasure spasms...My nipples are more sensitive than usual...I feel "more electric" all over... then when she starts cumming it seems to be less intense than the greatest climaxes she has ever had but they last a long time...then I start cumming, and cumming, and cumming, and cumming...OH YEA!!!, that was awesome! If you haven't had a Double Whammy you are missing out.
