"Hey dick! Where are you?" I called hesitantly, not sure where Mark would show up. I clenched the towel tightly between my breasts and made my way towards his bedroom.
"Downstairs! I left clothes on my bed for you!" Mark called up the stairs. I ran into his room, closing and locking the door behind me. Safe. For now.
I looked over at Mark's bed and noticed that he'd stripped it bare. He must have grabbed my clothes on his way down with the laundry. Clean sheets were sitting on the corner of his desk, so I grabbed them and started to make the bed for him. My towel slipped off but I let it drop to the floor as I reached over to tuck the sheet under the last corner. I stood up and looked around for the pillows. They were on his desk chair. I grabbed them and threw them on the bed too. I picked up the clothes he'd laid out for me off the floor where I'd knocked them.
I held up the clothes in front of me and checked them out hesitantly. He'd given me a pair of his boxer briefs, grey Calvins, a red t-shirt, and a pair of grey cut-off jogging pants. I stood there, naked, in Mark's room and looked around again. It felt so weird standing there like that.
Suddenly I decided to be bold and started to walk around and check his stuff out. I went over to his dresser, on top were four framed pictures. One was of his mom and himself, the other three were of Mark and I. One was from our trip to the beach when I was fourteen, just beginning to grow...
I thought I heard the doorknob turn and I jumped away from the dresser and scrambled to grab my towel again. The doorknob stopped as it contacted the lock and I heard a muffled giggle.
"What are you trying to do? Lock me out of my own room?" Mark asked through the door.
"What do you think? I am getting changed in here, you know." I replied snottily. There was a locked door between us, he couldn't get me for being snotty this time. I reached over and grabbed the t-shirt and pulled it on over my head quickly. You just never know, locks do give out when pushed hard enough.
"Chicken!" Mark yelled again. "I'm gonna hop in the shower, I'll be out in a minute. You'd better be done getting dressed cuz I'll be coming in no matter what." Mark warned and left.
I toyed with the idea of not being dressed when he returned. What would he do? Would he really show me how the big boys play like he'd promised earlier? I contemplated letting him and suddenly realized I was very damp between my legs. I couldn't believe he was making me crazy like that.
Just to show him who was boss, I went over and sat, with my legs apart, on his desk chair. I then wiggled my bottom around, making sure that I'd got the chair good and wet from my wetness.
Yes, that should show him.
I realized that the fabric of the chair cover was slightly rough, and discovered that it felt nice rubbing against my skin like it was. I wiggled a bit harder, pushing myself into the chair more. I held the sides of the chair and tried to pull it up closer to me as I rubbed myself against it, back and forth, side to side. Back and forth felt much nicer, so I did it again, and it felt so good.
I felt my stomach start to knot up and I was tingling down there like I'd never felt before. I continued to rub myself against the chair, pushing as hard as I could into the fabric, until, oh wow.
I think that was an orgasm. My first one. My body shook and I had to grab onto the desk for support. I felt my knees disappear and my heart was thudding in my head so hard I thought I was going to die. My whole body pulsed with pleasure and it felt like I peed all over the chair. Oh no! I didn't pee on the chair!? Nope, that wasn't pee. Oh wow. How was I going to clean that up? The chair was a mess. Oops.
Hadn't exactly meant for that to happen. Mark would die if he'd known what I did, and I had to clean it up quick because the shower just turned off.
I tried to jump up but my legs wouldn't work and I almost fell face first into the side of his bed. I caught the edge of it and regained my composure somewhat. I pulled myself up and grabbed for the boxers. I managed to wiggle them on and then I reached for the shorts.
Too late.
Mark clicked the doorknob open and walked in. He was wearing his towel around his waist, and he looked amazing. I'd seen him with his shirt off before, but never with his chest glistening wet like that. His tanned skin and his muscles flexed under my scrutiny.
"Um, what...?" Mark started to ask but stopped as he surveyed the room. His eyes passed over the desk chair and paused for a second before returning to me.
