The cheapest 6 inch or larger subwoofer+amp you can buy

any pc/tablet with a headphone jack (pref. PC, because you can assign audio outputs with various apps)

Audacity

Generate tones in Audacity around 33 Hz (You can play around 0-60 Hz and eventually make 'songs' for your cock).

Run those into your sub/amp, place cock on subwoofer cone.

Profit!

X2 on the Electrolux vac. In terms of power tools I go through the phase from time to time, obviuosly pull the saw blades, and sand paper, first before you Mcgyver up something to make yourself shoot cum. If I was in such a mood again, I'd be looking at my palm sander, easy to control one handed, if you have one with variable speed two thumbs up. Pull the sand paper and replace it with some thicker furry fabric. Just a thought.

am going to get myself a massage gun , the orgasms look incredible .

Great advice.

Thanks for the advice

imagine 2 sanders, to squeeze and buzz

power tools, sanders...scary

I would recommend the back of an electric tooth brush held against the frenulum. Maybe not that strong vibrations, but very strong orgasms

Just get an Hitachi Magic Wand and you're all set. Gosh I've tried other 'things' over the eons and really nothing a wand. I bought one a yard sale. For something to use around the house, you might try removing the showerhead and getting off that way, using the firm, warm stream of water or a swimming pool/hot tub jet.

Gotta get me one of them

I guess that's not for me, just doesn't look strong enough now the vaccum does the trick every time.

does she know you're masturbating with it?
