I have a huge project due tomorrow for school. I was done setting everything up, but now I just need my partner to arrive so we can test the chemical. I have come up with a chemical that is supposed to make you relax, but I must need to make sure it works. Finally, my partner calls. Are you on your way? What, you can’t make it? This project is 50% of our grade! Great, now what am I going to do. I need a test subject. Is that you step-mom? I’m glad your home, I need a test subject for my science experiment. Will you help me? It won’t take long. Here, just take a sip of this potion and I am ...

I have a huge project due tomorrow for school. I was done setting everything up, but now I just need my partner to arrive so we can test the chemical. I have come up with a chemical that is supposed to make you relax, but I must need to make sure it works. Finally, my partner calls. Are you on your way? What, you can’t make it? This project is 50% of our grade! Great, now what am I going to do. I need a test subject. Is that you step-mom? I’m glad your home, I need a test subject for my science experiment. Will you help me? It won’t take long. Here, just take a sip of this potion and I am just going to time you and see how you feel. Don’t worry step-mom, it’s safe to drink. She took a sip and immediately it started working. She said she felt hot, but then she started acting strange. She began touching herself and touching me. I stood up to check on her because I was starting to get worried, but as soon as I came close to her. She was trying to unbutton my pants. What are you doing? Stop! You have a deep yearning and craving. She grabbed my hand and put it between her legs. Your vagina is very wet and hot step-mom. She unbuttoned my pants and starting sucking my cock. She was so horny and going crazy for cock. She pushed my down on the chair and fucked me hard. Wow, this potion is awesome! It turned her into a cum slut! I can’t believe I just fucked my step-mom and I busted a load all over her face and tits. The only thing, she did not remember once the potion wore off. I am definitely going to have to perfect this serum.
