MFTH-006 Temptation type! Men are played with like toys! Little devil girl rolls the dick in her palm! Sticks out big ass, plays with clit, sucks on the dick! Insults to extract semen for research material sperm! 【The insatiable curiosity of the Biology R

I heard that the biology research department was recruiting sperm for an experiment, so I went to check it out and got hired on the spot. Then, a cute female science student milked me dry!
"Can't you shoot a little more?" For the sake of research, I was made to go until I couldn't produce any more sperm!
Temptation series! A little devil of a science girl who plays men like puppets
Sticks out her big ass, fiddles with her clit, and sucks on my dick!
For the sake of research material, I was shouted at until I ejaculated!
Hey, why am I not getting hard today? What's going on? You're not excited by me?
What do you want? Imagine being touched? If you don't cum soon, I won't be able to collect it...
Pathetic. You like this kind of thing, right? You get excited, don't you?
Don't you feel ashamed? If it were me, I couldn't bear it. To think I'd be sticking out this ugly dick and jerking off
Wasteful~ It's better to shoot out lots of dirty sperm! I'll do plenty for you too. Remember, I like rubbing my clit
How is it? Can you feel the erect clit? This is my favorite spot
To think you'd show me masturbation but not cum. Let me help you climax more
I'll personally take care of you. You shot out so much thick stuff
Can you still cum? Make me feel good too
Special reward! Slowly... Hey! Don't rush it!
Yeah, start slow
Feel it more! With my pussy! Right there in the back! Ahh... I'm going! I'm cumming!
