Get girth and length, then she can take as much as she’s comfortable with.. Vibrating is a lot more versatile than thrusting..
If you don’t mind forking out some serious money, consider an electro stimulation control box and toys that connect to it.. If you get a dual channel box you get run two toys at the same time.. Some toys, you can run two from a single channel box but only at a lower intensity.. An electro stim dildo in her cunt, and an electro stim anal wand in her ass is one of the few things, other than fisting that will have Lynn squirting..
