She almost lost her wallet but found crazy sex

Friendly speaking I've noticed her ass in the beginning. Her tiny butt in blue jeans made me crazy and my dick in my pants was agree with me. Later I've noticed that her wallet is falling out from her backpack. That was my chance to start conversation. She was so glad that even offer me some money and it was perfect time for response offer. Would you sleep with me for money, babe? I asked. She said 'No' and went away with her boyfriend, but I kept my camera on, coz I saw - they have doubts and maybe they will come back soon. Lucky me - they did! I invited them to my apartment and on our way there I was imagine how I will kiss and squeeze her wonderful ass...
