ROYD-324 - My friend's sister hates nerds but is obsessed with my d*ck

I went to my friend's room and ended up stuck with his sister, a gal who absolutely hates nerds. She immediately told me off, but when my friend stepped out, she made a deal: money for a handjob. I got played, but soon realized she was actually addicted to my d*ck. Now, she acts cold in front of my friend, but behind closed doors, she's begging for it non-stop.
