Nowadays, with the constant use of cell phones, anyone can make a very embarrassing mistake. My stepsister-in-law mistankenly sends me sensual photos that were intended for my stepbrother. At first I didn't pay much attention to it, because I never saw my stepsister-in-law in a sexual way, but when she continued to send me picture showing me the nice boobs she has... I couldn't help myself. Yes, I sent her pictures of my dick. She saw it and at first didn't believe it was real, so I went up to her bedroom to put my dick in front of her face. She confirms that I have a bigger dick than my stepbrother and since I am a very generous person, I gave it to her for her to play with. I must admit that I didn't expect my stepsister-in-law to enjoy cock so much!
