Shrinkage cream

The day started strange I had big rash on my dick it was sore and itchy. I went for cold shower which helped a small bit, I went  back to my room in just my towel my phone peep it was snap off a Grace a girl I was trying to fuck. I wipped off my towel and sent back a pic, she was in aw of my big cock I was around 7 inches limp and grew to just under 9 hard I got some nudes off her got hard and sent back but my rash was coming back. I went to the bathroom again on the sink was a cream with a load of hippy logos probably my step sister's she is in to that save the world crap. I put on the cram it felt so good it cooled me down and hep me forget about the pain. As I left I  bumped into my step sister who gave me an evil looking smile and spoke "enjoy my muscle cream big bro". I gave strange look and continued to my bedroom. The next few days went the same way I woke up with rash and put on the cream and it help but I was in trouble it was running out, but I was about to be in bigger trouble after about a week I got the shower and thought my dick looked way smaller I went to my bedroom and measured I had gone down to 3.5 inches and the cream was now completely gone I knew I was in trouble, just then I noticed my step sister at the door laughing. Looks like my shrinkage cream is working I heard you were big bro but now you are like a little kid. I was in shock but didn't know what to do I still had my rash coming and the pain was unbarable I went to my step sister to ask for more cream but she was with her friend Amber who I fucked a while back and ghosted, as I entered her room "oh heres my big bro now Amber" she said. I looked down and asked if I could have more cream they both laughed and she said sure just so Amber your cock, I was always so confident showing off due to my size but now I was kinda nervous so I pulled out my cock Amber fell off the bed laughing "oh my god it's shrunk so much" Amber said through the laughter. My step sister passed me the cream and I left even more embarrassed. I used it for few more days and my dick shrunk further now I was maybe 1.5 inch soft and grew to just under 3 worse of all I had a date with Grace coming up I had wanted to fuck her in my car and said I show everyone her nudes if she didn't go along. I was thinking about pulling out when my step sister called me into her room she was having a sleep over with a few friends including Amber and 3 other friends. "Hi Big bro we want to check your progress drop your pants" I was too scared to fight back I dropped my pants there was more a stunned silence for the first few seconds and then a heard of laughter from the girls. "Lets measure him, Amber why don't you do the honors" my step sister said handing her a ruler. Amber stepped forward "its hard to find " said Amber laughing " 1 inch soft, I'll try get him hard last time I was working with something much bigger" Amber said as all the other girls laughed "wow a whole 2 inches". I was so humiliated infront of all the girls I just stood with my tiny hard dick out with everyone still looking, my step sister finally spoke " ok bro I think to really learn your lesson you should go on your date with Chloe she's a real size queen she will destroy what little manhood you have left." I left the room got dressed in my room went and collected Chloe we drove just outside of town somewhere quite things stated getting heavy whe was begging for my big dick she was expecting what she had seen in old pics. Before I could plan a way out Chloe reached out for my dick everything stopped Chloe burst out laughing " oh my god did you use photo shop or what you have the worlds smallest dick I want you to get fully naked and give me your phone". I started getting undressed as I could see Chloe deleting all the nudes off my phone  she then took a pic of me naked and set it as my profile picture " now get out and never go near another girl with that tiny dick you loser". I slowly got out as Chloe drove off in my car I started to walk home through a busy town fully naked there was no point covering up now everyone would soon know I had the worlds smallest dick. So I walked through my town completely naked passing huge groups and couples getting looks of shock soon followed by laughter as well as mean comments. I finally got home but the door was locked I knocked and my step mom answered with my step sister in the background, she looked down and laughed “oh honey it most be so cold out look how much you shrunk” my step sister was laughing in the background and filming on her phone. My step mom continued I guess you worked out now we were unhappy with how you were treating girls so we thought you a little lesson with some shrinking cream. Both women laughed as I just stood naked totally humiliated finally my step mom pulled forth a clothes bag and said I still think you need to learn how hard women have and since you no longer have a penis you will have to be a girl goring forward as she handed me the bag full of thongs and other panties with some dresses and skirts I placed the bag and slowly got dressed in flowery knickers with a summer dress to match not sure what to was to come next.
