Hell No!

A ding was heard on my phone once more, the afterglow so beautiful I could only move my arms to pick it up after a good 30 seconds.

+80points for sexual act!

Looking over the phone, I realized this app was insanely valuable. But I knew next to nothing about it. I decided to change that. Reading all the rules, I could only blink my eyes in disbelief. If it weren't for the fact that I knew it all to be true, I would think this app was a scam. But since I knew it was real, only incredibly hot things filled my mind. To the point that my cock, even though it had cum twice only a while ago, smacked the bottom of the table.

Swallowing hard, so many fantasies filled my mind, fantasies that I knew my step mother would now demand to know so that she could make me cum. However, it wasn't the morality that caused me to pause, but the fact that I couldn't stop thinking about one fantasy in particular. But if I go through with it, I didn't know if I would survive.

"What's the worst that could happen?"

Despite the risks, my cock was throbbing desperately for more. Fuck work, if this effect only lasted today, then I wanted to make the most out of it. Standing up, I quickly ran upstairs to my room, pulling out my box of toys from my closet. If this was going to work, I would probably need to go to the sex store and buy more things.

Tossing that thought aside, I moved to my step mother's room. Her large four post bed was perfect for what I had in mind. Placing the box of toys on the bed, I then went to the restroom to empty my bladder, drank a bit of water from the fridge, and then returned to my step mother's room, right as she left the shower for a second time.

Seeing me, Julia raised an eyebrow, but before she said anything, I pulled down my pants, my erection throbbing in the open air. Seeing my cock again, Julia only chuckled.

"Young men really are insatiable. But I knew what I was getting into when I chose to take care of your erections."

Before she could come over and grab my cock though, I raised a hand.

"I will only be satisfied today if you help me play out a fantasy. Are you willing to help?"

Julia raised an eyebrow.

"Of course! Your erection is my responsibility after all. What kind of fantasy?"

With a hard swallow, I opened up the toy box which made Julia blush a bit as she spoke up.

"Let me guess, you want to tie me up? Just so you know, we aren't having sex, but if you want to use my tits, mouth, hands, feet, whatever, we can do that."

I shook my head, which caused Julia to scrunch her eyebrows as her massive chest bounced a bit in confusion.

"I want you to tie me up, pleasure my cock to orgasm after orgasm and not stop no matter how much I beg, scream, etc, although you should gag me, until a certain time."

This made Julia swallow hard and slowly drop the towel. Her bare breasts shooting up as her nipples hardened. I could even see Julia lick her lips as she stared at me hungrily. My cock throbbing at her sight.

"Anything else?"

I nodded. This was the moment of truth

"You secretly have wanted to do this to me ever since you saw me jerk it. You know it's your duty to take care of my erections, but ever since you saw me jerk it, you have wanted to punish my naughty dick by making it cum as much as possible. My cock cumming itself silly is all you have been able to think about, and that thought it turns you on so much. Now that you get the chance, you are going to show my poor sensitive cock no mercy."

A ding was heard from my phone, letting me know my BS worked. But I didn't need to hear the ding to know that it worked. Julia's eyes had quickly turned predator and my cock couldn't get harder. I swallowed hard, as she leaned down, grabbed my hard cock with her hand, and whispered in my ear.

"Get on the bed my naughty ****."

It only took a few minutes to tie me to the bed in an X. The bed posts doing well to keep my body taunt. When she gaged me with the gag, I could only shiver and throb in excitement. However, what happened next went a bit out of my expectations. Julia quickly walked over to her closet, pulled out a large box of her own, and began to take out straps. My eyes widened as not only were my arms and legs tied to the bedposts, but my thighs and chest was tied to the bed, connecting to something under the bedframe itself. Now I couldn't even buck my body!

She knew what was going through my mind as she ran her nails up and down my throbbing member, over and over again. The subtle pressure on my cock by her nails not enough, but just enough to make me want to buck into her hands. She winked down at me as her nails continued to teased me. The look she gave was one of a predator studying their prey, looking for all the weaknesses. She soon found one, the sensitive spot right under my head. Like an angle of pleasure she grinned wickedly, spending a good 10 minutes or so, just using her nails to torment that poor sensitive spot specifically. I couldn't take it, but I was **** to. It was heaven and hell at the same time!

"Oh? Does this spot need some special attention? Is it not enough to push you over? I bet I could make you cum from this though. Over and over and OVER again. My poor naughty cock. I am going to fulfill your fantasy, but you might not like how long I pleasure this poor sensitive cock of yours. So naughty. But you will have to take it."

With a dark chuckle, Julia climbed on top of me, her eyes meeting mine as her thighs trapped my cock between them. I could feel her wetness as she slid my throbbing cock up and down. I nearly blew my load right then and there! But she wasn't done with me. Not even for a second, and I loved it!
