"He's watching again now, isn't he?" Mark asked.
It had been a few days since The Show, and Chris had been at his window watching me touch myself as I chatted with Mark every night since. The only time I didn't see him was when Mark was over. That time, Chris seemed to keep himself hidden behind his blinds; though I suspected he was still peeking through and watching.
"Yes," I said, sitting on my bed and looking out the open window across the room.
"He's standing in his window, rubbing himself through his shorts."
"You want to put on another show for him, don't you? You like knowing he's watching."
I sighed into the phone, leaning back onto my elbows and propping my feet up on the edge of the bed frame, spreading my legs. My right hand slid down to rub my pussy through my shorts and panties almost involuntarily. "Yes. It turns me on a lot to see him watching me as I touch myself. And thinking about how long he might've been watching before I noticed."
"He must've seen you cum so many times. By yourself: with toys and just with your fingers, while we've been on the phone or texting. With me, while I've been there fucking you."
"Fuck..." I muttered, my head rolling back. My pussy throbbed and clenched at that thought.
"Tell me again: what made you cum for him while you were watching him jerk off?" Mark asked. "What were you imagining, specifically?"
I slid my hand into my shorts and panties, rubbing my bare pussy, sticky wetness immediately coating my fingers. "I was thinking about feeling him inside me. Behind me, fucking me hard. Pounding into me. He was still so hard, even after he came."
Mark groaned. "You want to feel that big cock inside you?"
"Yess," I admitted easily.
"You know he wants your pussy. Watching you every night, whenever I tell you to leave your curtains open."
"Oh my god," gasped, rubbing faster.
"Are you touching yourself now?"
"Yes. My hand is inside my shorts and underwear."
"Take them off," Mark ordered. "Your shirt and bra, too. Get naked and give him a proper show."
I moaned and reluctantly stopped touching in order to strip. Without getting up, I pushed my shorts and panties down over my hips and ass, lifting to get them off.
As I sat up to pull off my shirt and bra, I couldn't resist looking across the street at Chris, biting my lip to keep from smiling too much. He smiled back and pulled his hard cock out of his shorts to stroke.
"Tell me what he does when he sees you get naked," Mark demanded.
"He just pulled his cock out of his shorts. He's stroking now and watching me."
Mark groaned. "It's so hot to think about him watching you like that."
"Yeah?" I asked, rubbing myself a little faster.
"Yes. Knowing how much he wants you. How much he wants to feel your pussy around his cock. And your mouth."
I never would have expected Mark to get turned on by the idea of me fucking another guy. What we had obviously wasn't a typical relationship, but it still felt strange to talk so openly about it, much less to hear him encourage it. It was also surprising to realize how much that turned me on, too.
"I have a video I want you to watch. I'm sending it to you now."
"Okay," I smiled and laid back on the bed, holding the phone with both hands, switching to speakerphone and opening my text messages to wait for the link.
"Just sent it," Mark said after a moment. "Let me know when you press play."
"Okay, I'm opening it now." I noticed that the title of the video referenced multiple cum shots and smiled, knowing what Mark must've been searching for. "Just waiting to skip the ad," I narrated. "Playing now."
As the video started, I saw a guy with a big, hard cock sitting in a chair, and a girl sucking him off. She was focusing mainly on the head of his cock, sucking hard, her lips wrapped tightly around him and rubbing.
"Is that how big your neighbor's cock is?" Mark asked.
"Pretty close," I admitted, thinking that Chris might actually be a little bigger.
"Are you imagining his cock in your mouth like that?"
"Yeah," I sighed, switching to hold the phone with my left hand while the right slid back down to my pussy. I dipped my fingers inside and then rubbed the wetness around my clit as I continued touching myself.
"You want to feel his big, hard cock between your lips, don't you?"
"Yess. I want to make him cum in my mouth. I want to feel it shooting down my throat."
"Mmm. Is he still stroking for you?"
I looked back across the street to Chris, watching his hand slide on his cock. Then I imagined him in my room, sitting down on my desk chair while I got on my knees in front of him, just like the couple in the video.
"Yeah," I answered. "Are you?"
"Yes," Mark answered. "So hot thinking about him watching you. And hearing you tell me you're thinking about sucking his cock while you play with yourself."
Before my mind could wander much further, the guy in the video was already cumming in the woman's mouth, less than two minutes after she'd started sucking. She slowed the bobbing of her head on his cock and opened her mouth slightly wider, allowing his cum to drip from her mouth, a thick white stream slowly dripping down his still-hard cock as she continued sucking him.
"Fuck," I breathed, feeling my pussy clench at the sight.
"He came so fast in her mouth," Mark noted.
"Yeah. And he's still hard," I added, smiling. "She's going to make him cum in her mouth again."
"Yes," Mark confirmed. "Just like your neighbor came again for you, on his window."
I moaned and rubbed faster over my clit, glancing back and forth between Chris and the video. He appeared to be getting close: his eyebrows furrowed, and he was stroking fast. I couldn't help wondering what his reaction would be if he could see the video, too; if he knew what I was thinking about.
