[Belly Button]

Simulating in public is something I highly doubt I'd ever have the courage to do - so well done to you there! You're certainly much braver than I am! 

To answer your questions: I'd happily have a woman play with my belly whether I was simulating pregnancy or not. As long as it was in private. I'd probably want to put that on my 'bucket list'. My only advice when it comes to making your belly look bigger (I personally prefer bare belly/natural inflation) would be the usual tips of eating a heavy meal and drinking lots of fluid. Allow it to settle for 20 minutes or so and then 'pushing it out' should give some good effects. On top of that, wearing tighter clothes always gives the impression of having a 'bigger' belly. I personally like wearing t-shirts which I can adjust accordingly to show varying degrees of bare belly. Similar in style to a crop-top. I've stuffed to simulate on multiple occasions in the past - but I have to stress that's not to the extent others go to and barring pictures I've shared with our community in the past, it's been in private. 

I hope that helps.

Please do keep us updated on any future excursions!
