I found a DVD hidden in the corner of her desk! When I looked secretly, I saw a video of her getting fucked by a bunch of guys! She was so turned on by the guys' fingering that she happily gave me a peace sign and greedily sucked the guys' dicks into her mouth, straddling them and shaking her hips! She even did creampie sex, something she would never do to me! My dick was trembling with anger...it was rock hard! We'd been dating for two and a half years...and I'd seen a side of her I'd never known!
