Making sure you always get something out

Last night my wife let me tie her legs together and her arms behind her back. I pumped her delicious smooth puffy little brown vagina ruthlessly for about half an hour with my thick white dick. I was withdrawing almost entirely and then plunging it back in. After a while I worried it may be hurting her so I asked “shall I ease up” and she hesitated then whispered very quietly “no, take what you want”. Her legs were not wide open, they were closed, and she felt exceptionally tight.
