Oh I'm glad you agreed to come to my lab to help me out... as I really need you to assist me. I need to check my sperm under the microscope and I was hoping you'd suck my cock to get me hard so I can cum on the slide. I'll tease you with the bulge in my panties and have you lick my round transsexual ass to help get me excited. Then I'll encourage you to get on your knees in front of my thick hard cock. Looking up at my big cock, I'll have you work your lips up and down the precum covered shaft just like my fingers until I finally cum all over the slide. We're doing it all for science baby! ...
