I sit on the couch, watching a pointless Cinemax skin flick, it has something to do with cloning young coeds. My penis is beginning to stiffen, but my thoughts are not with the movie. In the bathroom my roommate, my couch surfing best friend more exactly, is taking an evening shower. As I wait for her to finish I begin to drift into the movie. I cover myself with a blanket and begin to casually stroke myself. Once I've begun to focus on the move my best friend emerges from the bathroom, she's wearing a oversized t shirt and some loose fitting boxer shorts. She sits down cross-legged on the couch and eagerly asks me what I'm watching, I bring my arms out from under the blanket, lest I give myself away and tell her that it's a terrible skinemax sci-fi flick. "Really?," she asks excitedly "how terrible is it?". It's awful I assure her, as bad as any of the movies we watched in our b-movie phase when we were growing up. She starts watching the movie and soon pulls the blanket to cover herself. My penis is still outside of my pants, though at first she doesn't notice. She lays back on the couch and settles in to watch the movie. During a mindless sex scene she repositions herself, pulling the blanket up to her chest. After she pulls the blanket up her arm stretches out and her forearm grazes my erect penis. She pauses, surprised. She doesn't know quite how to react at first, she decides to make a joke of it. "Ah ha, so that's why you're watching this!, tee hee silly boy". I blush, both embarrassed and turned on. "well, a boy's got to do..." she chuckles and returns her attention to the movie. After a moment I get my nerve and put my left arm under the blanket. After a few seconds of just resting my arm under the blanket I begin to stroke myself. "I'm sorry, I shouldn't be doing that" I say stopping, pulling my arm out from the blanket again. "Oh don't be silly" she says "we're best friends, we've watched porn together before. It's okay" I think about protesting, but quickly realize that I may convince her that it's not okay so I shut my mouth. For the next 20 minutes I occasionally touch myself, but not too much. I don't want to come yet. In the middle of a particularly erotic lesbian scene I see her focus intently on the action. "You know," I say "you can masturbate too". I can tell her first reaction is to say that she doesn't need to, but she pauses. "You're right!" she says throwing caution to the wind. At first I can't tell if she's doing anything or not, but soon a small sigh escapes her lips. She notices me watching her and she smiles. I blush. "How are you doing?" she asks "Perfect" I tell her honestly. "Just perfect". "Yeah?" she says, reaching over. She touches the head of my penis with her fingers, sliding them around the pre-cum which has enveloped my penis. "Yup, I think you're doing okay". She keeps her hand on my penis, I sit back and sigh. She looks into my eyes and smiles, her hand beginning to move up and down the length of my penis. My breathing gets shallow and quick, she doesn't take her eyes from mine. A small moan escape my lips "Oh, I'm going to..." She tightens her grip and works her hand over the top of my penis. She smiles as she feels the stream of cum burst up and out of my penis. I reflexively move my hips up and down. I have the best orgasm of my life, I cover the blanket and her hand with cum. She looks into my eyes and smiles. She stands up, kisses me on the forehead and goes to the bathroom to wash her hand off.
