The thought of smothering my body in them was repulsive. Besides, she'd asked for it, hadn't she? I opened my door and stepped out into the hall, feeling every stray current of air that brushed my bare skin. I looked toward her room, thinking maybe Sis was already in there, doing her homework, but her door was wide open, which meant she was probably still down stairs. Taking a deep breath, tingling all over, I started down, my hardon swaying heavily with every step. "Oh!" Sis appeared at the bottom of the stairs from the direction of the kitchen, and froze like a statue. Her eyebrows went up and her jaw dropped. "I - uh - forgot my books," I stammered. Her eyes darted this way and that, flicking back to me, then scampering aside. I stood on the stairs, about six steps up, one foot on the next step down from the other, hand on the railing. I was that aware of how I was standing! "It's okay to look. I've been stared at by at least half the school at this point," I reminded her. She was blushing. "Oh, okay - uh - sorry. Your staff - uh, stuff - is in the kitchen." Ignoring her Freudian slip, I advanced down the stairs. "Thanks." Then I had to stop, because she was still blocking the bottom of the stairs. "Sorry," she apologized again, getting out of the way. "It's okay, squirt," I assured her, turning toward the kitchen. She was still at the bottom of the stairs when I came back with my books and trombone. "If you've got any questions, I'll be in my room." A few minutes later there was a timid tap on my door. I blanked my computer screen - a chick in a bathing suit danced on the monitor. Thinking maybe I should get rid of that screen saver, I swiveled around, my cock standing up from my lap. "Come in." "Uh - hi," she greeted me timidly, advancing warily. "Uh - you said if I had any questions." I stretched, folding my hands behind my head, leaning back in my chair, crossing my ankles, my hardon flopped up on my belly. "Ask away." "I didn't realize it was so big!" she observed, staring unabashedly now. I shrugged. "Some are bigger, some are smaller." I'd been doing some research on the Internet. "I guess I'm about average, from what I've found out." "What does it feel like?" "You can touch it, if you want," I offered. "NO! I mean, what does it feel like to - have that thing hanging down there?" I looked down. "It's not exactly hanging, right now," I pointed out. "Uh - no, but I mean, when you're standing up." I pondered this. "I don't know. It's just sort of there. How aware of you of, say, your nose? Anyway, it's not usually hard, you know." "You're excited," she pointed out. "By me." "Don't flatter yourself, squirt," I said teasingly. "At my age, I can get a hardon for no reason at all. It can be really embarrassing when it happens in class. Or, at least it used to be embarrassing," I corrected. "Now I just ask for relief." "Relief?" So I explained how having a hardon for a long time can start to hurt. "So I can masturbate during the first five minutes of class if I want to, which I do, if I've been hard for long." "In front of the class?" I nodded. "You've heard?" She nodded, still staring at my dick. "But I didn't believe it." "Believe it." "You said I can touch it?" I nodded. "If you want." She started to reach for me, and then hesitated. "Maybe later," she said, blushing. "Uh - it's your turn to do dinner, remember." "Yeah. Are you done? I've got work to do." "Oh, yeah, sorry." She backed out, still staring. I kicked the door closed behind her and turned back to my computer. I managed to concentrate on my physics homework enough that my hardon faded away. It was back, though, when I was setting the table and getting dinner ready. I wondered how Mom was going to take this new development in my progress. "Oh!" "Hi, Mom, how was work?" I asked, watching her expressions shift from surprise to curiosity to - something I couldn't quite read - to carefully schooled calm. "Hi yourself," she responded a little stiffly. "I see you've - uh - taken the next step." I looked down at myself. "I guess you could say so." "How did your sister take it?" I shrugged. "Okay, I guess. She had a few questions. You might ask her how she feels about it. Dinner will be ready in half an hour." "Okay, thanks." She was obviously working very hard to make everything seem very normal. "I'm going upstairs to change. Would you pour me a glass of wine, please, and put a couple of ice cubes in it?" "Sure." I reached for a glass for her. She hesitated in the doorway. "And, uh, could you maybe dress for dinner? I'm not sure we're ready for your full display while we eat." I laughed. "Sure. You want me to put something on now?" "No, no, that's okay," she gave a wave and disappeared. A few minutes later she was back to claim her drink. "Thanks, honey." She touched my bare waist as she reached past me for her glass, then seemed to jerk her hand away. "You're welcome." I was tingling from her touch. Skin to skin contact in those areas wasn't something I was used to, and I wondered if I ever would be. I had the feeling she wasn't comfortable with it, either. I threw on my gym shorts and a tee shirt for dinner, but even that felt restrictive. "Can I go naked around the house, too?" Dee suddenly asked as we neared the end of supper. I'd told them how it had felt to walk around naked, since they seemed to want to know. What felt weird, I admitted, was to be the only one naked in a crowd of people. It made me feel - "Exposed" just went without saying. I decided vulnerable was the best word.. "Do you want to go around the house naked?" Mom asked, managing to sound pretty calm about the whole thing. "I don't know," Sis admitted. "But it might make Carl more comfortable, think of that. Anyway, if I decide I'd like to try it, can I?" Mom mulled this over, while my dick, which had gone down once I'd dragged on my shorts, responded in its usual perverse way, swelling and growing like it wanted to craw out of the leg of my shorts to check on what was going on. "I suppose so," Mom agreed at last. "You're likely to be picked to do it around school sometime next year anyway." "Oh!" My sister sounded surprised, and worried. She looked nervously down at herself. She was wearing a cut off tee shirt and shorts herself, and I realized she was getting a bit of shape. "Oh," she said musingly. "Yeah, I might, I guess." Trying to will my dick down, I began to clear the table. "I'll do the dishes tonight. I'm pretty much done with my homework. Can I get out of these clothes now?" I asked. "If you like," Mom agreed, sounding a little stressed. "I've got some work to do, so I'll be upstairs. Is your homework done, Dee?" "No." My sister sighed wearily. "No TV until it's done," Mom reminded her. "Yes'm." After things were cleaned up and homework was done we all settled down to some TV, with Mom and Sis both trying to seem like everything was normal. I couldn't help looking at Sis, wondering what she would look like naked. Did she have tits yet? Or pubic hair? My dick stayed hard until I was up in my room, dealing with some e-mail, when it went down again. There was a rap at the door and Mom came in. Up periscope! "Don't stay up too late," she cautioned. "I won't." Then she really startled me by coming up behind me and putting her hands on my shoulders. Then she slid them down my chest, hugging me, resting her chin on my head, my neck nestling back in the valley between her breasts. Her hands were only a few inches from my still stiff dick. She kissed the top of my head. "You're very brave," she observed softly. I felt myself flushing. "Thanks." With a squeeze, she released me, and her fingers actually brushed the head of my cock. "Good night. Sleep well." "You, too," I responded, my whole body tingling.
