Oh and you should, trust me its awesome. I bet your master makes you feel so hot about doing it that your gonna get even more turned on. The first time i was able to see myself squirt and hit my partner in the chest was ....wow...hot.
The right person can keep you gushing and squirting for a shocking amount of time. Tip; drink a lot of water the day of and before. After all the ejuaculate is made mostly of water and if you are dehydrated you're not goona do it.
