My stepson and I used to be so close. We used to do everything together, but now that he has a girlfriend, she's always around and he has forgotten about me! I couldn't let that happen. I needed him. One day, I heard them having sex, and I got so jealous that I came up with the perfect plan. I started dressing exactly like his girlfriend without him noticing. Sure, she thought I was obsessed with her, but everything worked out exactly as I expected. All I had to do was bend over in the bathtub so he could see my perky ass wearing the same leggings as his girlfriend, but not my face. Just as I thought, he couldn't resist fucking me right there. His cock felt so good inside of me. I could have let him pound me all day, but his girlfriend caught us. I'm not her biggest fan, but even I have to admit that she's extremely hot, and I've been wanting to lick her tits since I met her, so I suggested something where we could all win: a threesome. Fucking my stepson with his girlfriend is way better than not fucking him at all.
