Mark and I had been in the same running club for about two years, since I met him in my first year at college. We'd also been on a couple of dates, but neither of us was looking for anything too serious. We'd been out, we'd kind-of made out, but really nothing more than "second base," so to speak. To tell the truth, we were both very busy and serious. While it was fun to hang out, that was about all either of us wanted to do.
One Saturday in October, though, that changed. We went for a buddy run on a trail out behind campus, and were gone for hours. Over that time, I couldn't help but spend some time looking at his body while it ran up and down those hills. I knew his legs were strong, and there was no denying that the squats were doing wonders for his ass. I found myself letting my mind wander while we came back around. As we neared the road behind the rear entrance to campus, I spoke up, "Why don't we go to your apartment, instead? I think we've missed lunch at the cafe."
He glanced at his watch and agreed. Instead of running into campus, we went down the back road known as Campus Row, where several apartment buildings offered off-campus housing to students. Mark had a room there with one roommate, who was usually not around on weekends. We walked the rest of the way up, and chatted a little. After the obligatory small talk about the run itself, I started moving in. "So, is Dennis around today?"
"No, he went home for the weekend."
"Nice," I said. "So, if I spring for pizza, can I grab a shower?"
Mark chuckled. "It's a deal."
When Mark opened up the door, I stepped in and immediately dropped my tank top beside his couch. As he closed the door, I turned around and faced him. "So, here's a question for you," I began. "Should I call for that pizza before I get in the shower, or could I talk you into joining me?"
He opened his mouth to say something, and stopped. He closed it again, then opened it again. His eyes drifted from mine to the top of my sports bra. It was a sports bra, hardly anything too exciting, but he did seem to enjoy a look at my 34C chest. He opened his mouth again. "Are you sure?" he asked.
"Do I sound sure?" I asked. I stepped forward, and placed a hand along the edge of his running shorts. "I think we should get out of these sweaty clothes, now."
With that, he flung his arms around me. His mouth covered mine, and our tongues flicked back and forth. His hands plowed along my back and I moaned into his mouth. We each kicked off our shoes, and after a minute or two, we made our way to the bathroom. He started the water, and I grabbed his shorts, catching the waistband of his underwear, too. I pushed it all down, and dropped to my knees to guide it down. He stepped out of the clothes as he pulled his shirt off and dropped it on the floor. He turned around to face me as I stood up, and his penis, hard and straight, pressed against my leg.
He reached around me and - rather expertly - unhooked my bra. He dropped it on top of his shirt and turned his attention to my shorts. He pushed them down in one easy motion, and I stepped out of them. I'd never actually showered with a man before. In truth, my sexual experience was pretty limited, but enough that I knew what I wanted today. Still, the whole thing was exciting enough for both of us that we made it through. I shampooed his hair, my hands rubbing to his scalp and producing plenty of lather. Meanwhile, his hands caressed my chest, in a pretty-nominal effort at washing me off.
As he got to work on my hair, I lathered up his back with a washcloth, and didn't stop at his waist. With both hands, I pulled on his butt and pressed him against me. That erection was begging for attention, and I wanted to oblige. I took the bar of soap and lathered both of my hands, then brought it between his legs.
"Oh, god!" he gasped as I began stroking his shaft with the bar. With my left hand, I ran lather around his balls and inner thighs. He leaned back against the side of the shower, almost panting, as I ran my hand along the shaft.
Smiling, and feeling bolder than I ever had in my life, I said, "I want it completely clean, for later, you know." He only nodded his agreement. A moment later, though, he recovered control and began soaping up my hops and things. He ran the bar of soap between my legs, now, and began stroking me. When he grabbed a clean cloth to rinse me, he slipped a finger inside. I squealed and nearly fell over, but he caught me. His finger slipped along the inside of my body, moving in slight circles. Then, he hooked it. "There?" he asked.
He knew exactly what he was doing, I realized. "Fuck, yes!" I panted as he ran his fingertip over my G-spot. I thrust my body against his hand while he stroked. His thumb made a small circle around my clitoris, and I called out. "God, Mark!" I threw myself against him for balance as my legs went numb. I knew I'd been horny, but a few seconds to orgasm like that? That was new.
