My girlfriends virgin sister stole my cum.  |  (Random)

I have a great girlfriend. We've been dating for about 6 months and things just couldn't be going any better. She comes from a really nice family that really treats me like I'm always welcome in their home. Her parents are super cool, and I think her little step-sister even has a crush on me. It's cute.

We were supposed to be going to go see a movie, so I arrived at her place a little early, hoping for a little alone time in her room before the show started. I let myself into her house using the key under the mat and wanted to surprise her. I looked around, but couldn't find her anywhere, so I popped into her step-sister's room to find out where my girlfriend was. Her step-sister is only 18 years old, and has always been a little shy and awkward around me. My girlfriend loves to tease that her lil step-sis has the hots for her boyfriend, but I just think she has an innocent crush.

When I walked into her room, her little step-sister greeted me with a big smile and told me that my girlfriend wasn't home and wouldn't be so for at least an hour. I was feeling a little frustrated because I really wanted my girlfriend to give me a blowjob before the movie. I was bummed, but her step-sister told me that I could just hang out with her. Why not, I thought. She's cute and I sort of like the attention she gives me. She must have been feeling a little bolder than usual, because she confessed to me that she did like me, and even more unbelievable – she was a virgin!

She had a look in her eyes that I have never seen with her before. I felt like she was going to devour me if given the chance. She reached across the bed and started feeling my crotch, telling me that she was very curious about guys and wanted me to be her first! I was nervous. I have never been with a virgin before. The thought was really a turn-on, and my cock began to respond to her touch. When she asked me to lay down on her bed so that she could jerk me off, I happily obliged this not-so-innocent virgin.

She took my rod out of my pants and began to slide her hand up and down the shaft. My dick was screaming for a little slippery wetness, when the next thing I knew she plunged her mouth around my man-flesh and pushed the entire thing down her throat. Her mouth was gushing spit and she used her throat-juice to lubricate my pulsing penis. Her step-sister's skills couldn't compare to this 18 year old cock-gobbler. She quickly popped her puffy titties out of her dress and got back to milking my dick. She alternated between her soft, tiny hand and her cupid-lipped suck hole. Looking into that innocent face, and hearing her tell me about how much she wanted to swallow my jizz drove me crazy. Soon, I didn't care if her step-sister got home early or not. All I wanted to do was to feed her cute little virgin step-sister. I blew a load all over her hands and she licked it up like a happy little kitten with a warm bowl of milk. After she slurped up every drop of my goo, she asked me to call her when my date with her step-sister was over. As long as she can keep our dirty little secret, I think I'm going to love teaching this little nymphet a thing or two.
