I feel so guilty
This has been stuck in my head for a while now, and it gets more tempting every day.
I'm a woman and... I've been fantasizing a lot about fucking my little brother. He's 22, I'm 29. It all started one night when he asked if he could crash at my place (he has a copy of the key), I was out and he was going to this party far away from his place, so I said it was okay. I returned the next morning expecting to find him having breakfast or whatever, and I'm greeted by her girlfriend moaning so hard the whole block could hear. So I open the door thinking I'll confront them on being so disrespectful to me and my place, but I freeze. It just kinda hit me that this kid I even held in my arms is now a grown up man pleasuring a woman... and I become curious. So insted I open the door to take a peek.
And I saw him, completely naked, so manly. I knew he was athletic and popular with girls, but seeing his muscles moving that way... and the bitch having the fuck of his life (I could understand why she was moaning that way, his moves were so hot). So I took a walk, went for coffee, walked in much later and he was gone... and everything had changed for me.
I've been thinking of him for weeks now. I masturbate and I picture him fucking me and I have this extremely intense orgasms. The idea of my brother fucking me gets me so hot and I'm very hooked on the feeling now, I masturbate more often and I only think of him now, it's just so hot, and I saw him on new year's eve and it was so awkward, it makes me feel so guilty to think of him that way. Has anyone ever experienced something like this for a family member before? Does this go away, ever?
