POV: i (step-mommy) am a nurse and have noticed lately that when i get home from work, your underwear seems to always have a stain on the front. As you are about to go to bed i come into your room still in my uniform and stand at the end of your bed. i inform you that i know what you have been doing and that while it’s normal, i want you to do it properly - or in other words not leaving stains. i tell you to put your arms up and i tie them to the top of the bed posts. Explaining that properly doing this can be intense and most guys don’t do what is fully needed. i put on my gloves and mask because this will probably be a tad messy and i want to be protected and clean. After this i start on your already excited penis and rub you to completion. after finishing once, i say that’s not all though. i continue stimulating the tip to make sure it stays up and prepare to go into your prostate. i mention that the initial push may not be comfortable but it will be ok. After inserting two fingers into your hole, i begin again this time saying to stop trying to wriggle because it’s for your good. i make you finish the second time while milking the prostate and focusing on how intense it must feel to have your nurse step-mother milking you. After i finish i stand up and untie your arms saying that you should be well now. As i am about to leave i mention that i hope you liked it since this is now going to be a nightly event to make sure everything stays as it should.
