I really, really wanted to fuck Theresa, but we were having trouble working out the logistics. In fact, we were having trouble just getting a chance to see each other. She realized that one of the drawbacks of still living at home with her parents was having to abide by their rules. And I guess when your parents are Costa Rican immigrants who are very protective of their exotic daughters, it is even worse. We talked on the phone when we could and I continually tried to figure something out, but it wasn't happening as quickly as we both wanted it to. When Theresa and I finally figured out a way to get together and indulge our mutual passion for each other, it came as more of a sudden revelation than as the fruit of our constant brainstorming. We were seeing each other occasionally, sometimes only briefly and rarely alone.
One night when she had to head home, I jumped at the chance to walk her. We approached Theresa's house from the alley that ran behind it, stopping near her parents' cars. In the shadows there, we started making out, my hands running over her ass and tits. She moaned that she wanted to fuck me so bad and apologized for not being able to work it out. I told her not to worry, that it would all work out but she was worried that I'd get tired of waiting for her. She said she had something for me, sort of a combined reward and plea to for my patience. With that, she dropped to her knees.
My cock was already hard from making out, so it popped out as she dropped my shorts. She gripped the base and immediately sunk her mouth down on it. She bobbed her head up and down, her lips sliding up and down my shaft, and gently fondled my balls. I was softly moaning encouragement to her, telling her completely honestly how great her mouth felt. As I was pushing my hips toward her face, enjoying the hot, wet confines of her mouth, I suddenly noticed there was tree in her backyard that would allow pretty easy access to the back porch roof. It gave me an idea, but I kept it to myself and let my focus go back to the lips wrapped around my tool. I grabbed the back of Theresa's head and held it while fucking her face, feeling that familiar sensation in my groin. Her hands were on my ass while her mouth maintained its grip and her tongue pushed against the underside of my cock. I closed my eyes as my orgasm came upon me, my hips stopping but Theresa going back to bobbing up and down, milking out all of my cum. Once she'd sucked me dry, she stood and popped a stick of gum in her mouth.
I asked her where her bedroom window was, thinking I remembered it to be overlooking the back porch roof. She confirmed that it was and I asked her if she thought it possible for me to sneak in if I climbed up the tree. She reminded me that she shared a room with her older sister, Elizabeth, so I asked if there wasn't a time when Elizabeth wasn't around and was there any kind of lock on the door. She said there was a lock and it occurred to her that there were a couple of TV programs that Elizabeth absolutely would not miss, so if I could come during that time it might just work out. The next night at 10pm was one of the times Elizabeth would be glued to the TV, so I assured Theresa that I would be on the roof by then.
It was actually very easy to get up the tree and onto the roof without being seen. I looked in the window and waited. The light was on, showing two twin beds, one near the window and the other across from it, among other furniture. When Theresa came in, she closed and bolted the door then came to the window and opened the screen. I crawled in onto the bed and she was immediately undressing me, telling me how horny she was. She had my shorts and underwear off and was fisting my cock as I kicked off my shoes and pulled my shirt over my head. I asked her if she was going to get undressed or was she going to finish me off with her hand. That broke her trance and she pulled her own shirt off, exposing her big, beautiful breasts and hard, dark nipples. She unbuttoned her jean shorts and, hooking her thumbs in the waistbands of the shorts and her panties, pushed them both down.
She looked so hot standing there naked, my cock twitched involuntarily. I had her climb onto the bed and straddle me, guiding my cock to her opening and pushing just the head inside. She took over and eased herself down slowly until I was completely inside her. She smiled at me and I asked her how it felt. She said it was even better than she'd expected. I reminded her that we had barely begun and had her start sliding herself up and down, trying different movements until she found what felt best. She ended up leaning forward on her hands, which I liked, too, because it allowed her full melons to hang right in my face. I licked and sucked her hard nipples while she rode up and down my shaft. She was breathing shallowly and moaning very softly, riding up and down faster and faster. I knew we didn't have a lot of time but I also didn't want to rush this too much.
