My older Step-Sister wanted me to go shopping with her to help her out at buying some sexy underwear, she thought that my manly opinion would be perfect to get the right pair. Little did she know that I have always had a fixation for her ever since I could jerk off I thought about her and used her panties to cum on. So we got back home and went upstairs to her bedroom to get a better look a what she bought with me."you know what would be great? If you could stay and tell me what you think If I tried them on and show you exactly what they look like when worn, you can maybe give me a better opinion... what do you say? yeah sure why not...So she proceeds to take off her tight jeans and high heels and then her underwear leaving all to be seen, " you've seen me naked a million times before step-brother don't be stupid"...So one by one she put on all of her silky sexy panties for show, while I was finding it harder and harder to stay focused on what I should be saying and not the terrible urge I was feeling for wanting to ram My hard cock in between my sexy sisters legs.A sudden urge rushed through my body and I found myself becoming more and more sexually aroused seeing her pose around in her silky underwear like that. Her eyes rolled down and she stared down at my crotch for a moment and said. "Is that...Is that what I think it is?""It's nothing," I quickly replied, pulling my Tshirt down over my tent."Did I just give my little step-brother an erection?" she asked with a grin."Oh god this is humiliating. What did you expect? you trying on all these sexy satin panties on and me being a that sometimes cant really help it when my dick goes haywire... you're really hot you know.."So you think I'm hot and now I gave you a hard on? Well I'm glad to know that family boundaries don't mean anything to you step-brother,"."Hey, I'm just being honest here. You're the one who wanted me to stay around well you whore all this sexy lingerie in front of me."And it worked didn't it?""Apparently so," I replied. "And I'm sure they would be of great use for you...? "There was a sudden awkward pause in the room as we both realized what she had just let slip. I was speechless and she looked like she was holding back her laughter."So...my little step-brother wants a blowjob from me huh? Or did you want to eat my pussy?" or would you like to cum on my panties? she asked with a smile.I tried my best to control myself. "My gosh, there's no way I can resist not touching this. Step-Brother or not, you've got an irresistible erection just pointing at me"-Her hand groped my cock and began to stroke me up and down. As expected, it felt amazing. The fact that I was getting a handjob from my own step-sister was an extra bonus since it was so not right."Holy hat feels fantastic," I sighed. "it's been a while since I've felt a nice cock like this in my hands. -Her eyes were glued to my manhood as she continued her handjob. Never in my life would I have ever imagined that I would be doing this with my step-sister of all people. The more she stroked, the harder I seemed to become and the more I wanted to fuck her. Suddenly, she got down on her knees."Can I suck it?" she asked innocently like it was no big deal.I nervously replied, "Um...yeah. Sure, if you want too."She continued stroking me while on her knees, and she gave the head of my cock a little kiss. (Spanish dialogue with English SUB)
