I just had to tell somebody so here i am. I am happily married man with a daughter and son. I have 17 year old daughter and 23 year old son who moved out already. Anyways, this happened last halloween. I let my daughter go to this party that was supposed to be for her friends only but i was called to pick her up at around 1 am due to police showing up. I went to pick her up and i could obviously smell the booze and weed. She was still in hee costume, a bumble bee. But she was carrying her friend, Julia to the car. I know julia, she went ove rto our house multiple times. Anyways she wa sout cold and i had to brig her home. I was clearly mad and dropped my daughter off first m since it was closer. But as i neared Julia's house i just stopped and pulled over into a empty park. I just couldnt help it. Over the many times she came over, i had been taking her panties to sniff and i ogled at her amazing body. I was having a decent amount of sex back home but it was gettig boring. but here i am, alone with a 17 year old completely unreponsive, dressed up as a slutty cat. I got out and went to the back. I pulled her rightto the edge and undressed myself. Taking my time i fondled all her fine assets. Finally i couldnt take it anymore, she was wearing cat ears, whiskers, a fishnet top with a lacy black bra for all to see. Then she wore a sexy leggings and a cat tail. I undressed her to find myself staring at the perfect c cup tits, and a completely naked pink pussy. I fingered her to find out that she wasnt a virgin. I entered my cock into the tightest pussy ever. I loved the look of the lips hugging my shaft. While pumping i sucked on the perky tits. I shot a huge load deep into her pussy, letting my dick stay in, i loaded about 3-4 good shots if cum. I pulled and cleaned off my dick with her mouth. I left the cum inside and redressed her. That is what i did. I am scared if she gets pregnate. I feel really bad but also i really felt young when i did it.
