Im a 27 yo Guy and i have this really cute niece(17 yo). She has never shown any sexual attraction to me, but i have always seen her in a sexual way. When my Brother asked me to look after her one weeked becasue he and his wife wanted to get away for a little while I saw this as a PERFECT opertunity to try and get her to like me. So they day came where my Brother dropped my niece off at my place i sayed good bye to him and they wnet off to there holiday thing. My niece loved hanging out with me and stuff i took her shopping and bought her some really hot shorts that defined her pussy lips to perfection. On Saturday night I was like to her, "have you ever had sex before" she took this as a violvation of privacy and then i sayed "dont worry you can trust me" she then told me that she has had sex and not to tell her parents. I told that i wouldnt and then i asked if i could have sex with her, she was like "What the fuck no" i was dissapointed. But after around a hour of her thinking about it she came and told me that she would acctualy love to. I was soo excited I asked her quickly if i could use submissive items and other Bondage items. she was like ok but nothing to painfull. I quickly ran to my room, grabbed some Rope and Hand-cuffs. I walked back down to her and then when i walked into the room she was naked, i quickly got a hard on for seeing my niece naked in my house. "you are so beautiful" I told her, she just blushed I walked up to her and grabbed her tits. They werent to big or to small just the right size for my hands, she then moeved her hand down to my ever growing slug. She undid my Jeans and then pulled out my log and then started to suck me off, I was soo surprised to see her getting straight into this. I then started to rub her pussy, it was soo wet, i put 2 fingers in her and she started to moan. She then told me to use the rope, I was excited I quickly tied her ands behind her back and her legs together and then tied them both behind her back. I then started to slowly fuck her in the pussy she was excited to try something new and she said she was enjoying it. The feeling was amazing I couldnt beleive it. My niece then asked me to fuck her in the ass, I was always against anal but her ass was amazing so i was like What the Hell. Her tight ass was amazing it felt soo good she was moaning so loud it was amazing. I told her i was about to cum so she was like let my ass take it so i did i came in her it was amazing, at the same time she came, after that we just layed there and made out I fingered her and she gave me a handjob every now and then. Up to this day we have been having sex when ever we can.
