A hand held portal made by DaVinci-chan? I'll take 20.

Base +6, tronix11 +6

Now you're thinking with portals. I wish more futanari manga had this portal selfcest thing going on

Base +6, tronix11 +6

greeeeeeeet!

Base +5

I didn't know whether to laugh or get aroused seeing the cover.
Da Vinci really did a wonderful thing making this!
I couldn't fap to this in the end based on my laughing.
Much as I still got horny.
Maybe in the future I won't laugh as much.
Either way, this is a gem.
Thanks a BUNCH!
