Another set of arms

Again, you rise up a feet into the air, and a blinding pulse of light envelopes you. For a second you feel discombobulated, but before your orgasmic wish-granting power has gently lowered back to the floor, it's clear that your wish has been granted. You have four arms. You inspect them, breathy and in disbelief that this is working.

Sophie:"O-... Okay!"

You stare open-mouthed while tossing and tumbling your arms around independently and with precision, as if it was the most natural thing in the world. Now you can wank off at all fronts simultaneously, and even spare an extra hand!

With wild abandon, you get right back to jilling off. These extraneous limbs as strong, deft and limber as your original arms, this feels like being the center of attention at a threesome. All in all, your new body is a powerhouse of pleasure, tweaked to the very edges of perversive performance in every measure. Both of your nipples and your clit get all the attention they deserve.

But then comes the question of what do you with your fourth arm. You could have it exciting your lips, your prostate, or even just have it play snake on your phone. But if you've got magic on your side, why settle for such mundane solutions? Instead, you'll just wish for a new erogenous zone to use it on.
