She just looked at me for a few minutes, a delighted smile on her pretty face, and then she reached for my t- shirt. She began yanking it up my body, ...o I sat up and let her pull it off me. She held it up by two fingers and, looking into my eyes, let it drop, almost ceremoniously, to the floor.I was naked, on my back on Alex's bed, and Erin was still fully clothed, settled back and sitting on my knees. I put my hands behind my head, in a posture much more nonchalant than I felt, and watched her. A moment later the teen was giggling nodding her head yes. Shelby looked at Derrick also nodding yes.Letting out a breath of air he'd been holding, Derrick noticed that the rest of the ships were there also. "Now 0808, do you have a name?"Nodding her head the teen female looked up, "Yes sire, I was called Radella for a very short time."Derrick smiled as he nodded. "The both of you will make fine additions to the growing fleet." They both bowed to Derrick again, then all the ships started. She said I'd have to jerk off because I wasn't going to get her pussy. As I began slowly stroking my rock hard penis I talked to her. I asked her to think up a way so I could watch her have sex . She said she would. The following Friday after work she showered and called me into our room. I found her butt naked and she had me undress and lay on the bed. My penis was already hard when I pulled down my underwear and she laughed at my lack of control. She sat beside me and took my penis in her. I spent the best part of the next 2 weeks in turmoil, I knew what we had done was wrong and had to be kept a secret but I was also a very horny 13 year old who wanted a repeat performance more than anything else. My masturbation habits went into overdrive as I would constantly relive all the events in my head, I would compliment Sharon at any opportunity, on her hair, clothes, make up, looks, wolf whistle her etc, hoping she would give in and relent to another session, but I always got the same.
