I hope you all enjoy this very kinky in depth taboo role-play! REAL TABOO KINK* Step-Mommy is a scientist and she's been working on a new top secret experiment, but she's been working too hard and has been making mistakes at the lab so she's sent home to rest. She brings home her experiments so she can continue tinkering with the new mutation serum from home.....but she doesn't expect what will happen next... YOU (her step-son) see the serum on the kitchen counter and confuse it for headache meds, you mention to her that you just drank some of the serum and she instantly panics!!! The scientist milf can't believe you drank her experiment!! She notices that your cock is already bulging and she knows soon you'll be horny and in pain!!! She acts quickly and starts sucking you off, apologizing over and over for doing this to you! She feels awful for what she's done to you, and now feels even worse that she's now sucking off her sweet boy!! She disgusted at first, but soon starts to enjoy tasting your cock!! The serum kicks in even more and your cock mutates into a big pink monster cock!!! But She doesn't stop, she continues to suck you off even after your transformation! She knows she has to fix this!!
