I was at my girlfriend Katie's house making out and about to fuck, when I noticed her pervy stepbro spying on us!! I could tell he had a huge boner, which was kind of hot... We made him get it out and jerk off to us whilst we fucked in front of him!! I loved licking his step-sister's pussy whilst he watched!! we took turns fucking each other until we knew he couldn't take it anymore, his balls were ready to explode!! We begged him to cover us in his cum, and he blew the biggest load all over our perfect bodies!!
