I have to admit, my Step-dad is quite a sexy older man. Now that I am 18 and grown up with such a womanly body it is going to be hard not to look at him in the way a daughter shouldn't. Guys my age are so immature and seriously dumb. My step Dad is refined and knows just how to make a girl feel special. I wondered what he was going to give me for my birthday present. He usually gives me a separate gift from the one he and my Mom give. Last year he gave me a gift card for a full day shopping spree at my favorite clothing store. I was sure he would give me an even better present this year since I am now legally an adult. He had me close my eyes and led me into the master bedroom. I wasn't sure what I was looking at when I opened my eyes. He said it was a sex toy. I had not ever seen anything like this before! He said I climb on and straddle it like I would a bike. He said the knobs control what kind of ride I would have on the toy. I could hardly wait to try it! I lifted my little jean skirt and spread my legs to carefully lower myself down. I turned on the vibration knob and Oh my gosh…my little pussy instantly became swollen and wet. This toy was the most powerful vibration I have ever felt in between my legs. My mom bought me some dildos and little pocket rocket toys which she gave me this morning before she left for work but none of them even came close to what this feels like. My Dad is the best. He knows exactly how to take care of a young sexually budding girl like me. I should give him a thank you that is equally as great as my new toy. I know I can't fuck him but I am going to make his cock feel better than it has in years. I saw his bulge growing as he watched me pleasure myself on my new gift. I knew the way he watched his little girl on this big sex toy that he was enjoying himself in a way I never expected but always hoped for. I like that his dick grew at the site of my young body. I knew he and my mom have a crappy sex life. I hear her complaining about it to her girlfriends all the time. Now I know why, it's because my Dad really wants to fuck me, not her. Now is my chance to show my Daddy what a grown up girl I am by taking care of his big daddy cock in a way I'm sure my mom has forgotten about. I want to clear his head from all worries as I milk every last drop of cum from his big dick. I want to make him feel so special that he wont even want sex at all with my mom, he will only want it with me. Since he works from home and I only go to college part time I am sure that will leave us with plenty of time at home, alone. This is turning out to be the best birthday ever. I can tell he is in my total control just by looking at my tight young body. I ask him to grab ahold of his stiff cock and rub it for me. I can feel my tight hole becoming moist as I watch him stroke his shaft. I ask if he wants me to take over the stroking. His slightly dirty grin gave me my answer. I had him lie down so I could get a good grip on his daddy dick. I stroked him with great fervor. I loved the feel of his quivering body under mine. I loved the size of his big shaft in my little hand. I love I was giving my dad a hand job on the very bed he and my mom go to bed in. I wanted him to know what a dirty girl I will be for him any time he wants. I can hardly wait for the next time we are home alone together because I know he wants to fuck my tight little hole, and I am going to let him. He must have seen this in my eyes because he let out a huge gob of warm goo. It spewed out and glazed my hand. I thanked him again for my birthday present and said with a gleam in my eye that I hoped he knew how truly appreciative I am. Starring Brooklyn Chase
