Your lab colleague comes over most days of the week to go over results from the most recent trials. You work in a highly competitive field, and your lab is known for pushing the limits of acceptable pharmaceuticals. Do you maybe try out your own blends, every so often? Sure, but who wouldn't, with access to a lab like that? Of course, you normally keep these experiments under lock and key. But you left a glass out. Stupid. Stupid stupid. And she drank it. ALL of it. You're curious, yes, to see the reaction, but...god, it's too strong. She's a woman possessed! She has to have you, any way she can. She'll have you forever, tied and strapped and hard and fucked and made to cum, over and over. You should have been more careful...
