"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.
"You want to try this with him, don't you?" Mark asked, as if reading my mind.
"Yes," I admitted easily. "I want to see if I could make him cum in my mouth repeatedly like this."
"I'm sure you could. Keep rubbing your pussy. I want you to make your neighbor cum on his window when the guy cums in the girl's mouth a second time."
"Fuck..." I muttered, my head rolling back momentarily as my pussy clenched, my thighs squeezing together. I pressed harder on my clit, rubbing in faster circles. "I'm gonna cum when he does, too."
"Good girl," Mark sighed. I could hear his breathing getting shallow, and the faint sound of his hand sliding on his lubed cock. "I want him to see you cum. I want him to know you're cumming for him, thinking about his cock."
"Oh god," I moaned, watching Chris, focusing on him. I watched him get close and then slow again. It seemed like he was edging, waiting for me to cum. I looked back at the video, imagining his big cock in my mouth, getting him close to shooting another load in my mouth.
About three minutes into the video, the woman licked up the rest of the cum from the guy's first load, and then went back to sucking hard and fast on his head. Moments later, her mouth slowed as his cock and balls pulsed fresh cum into her. And once again she let it drip out, for the benefit of the camera.
"He's cumming again. You want to see your neighbor cumming all over that window again, don't you?" Mark asked.
"Yess!" I hissed, desperately rubbing. I want to see him cumming on his window again as I imagine him filling my mouth, just like the guy in the video. "I'd be rubbing my pussy while I was on my knees for him."
"I know you would; you're such a good slut. You want to be a good slut for him, just like you are for me, don't you?"
Mark's words put me over the edge. "Ohhh god, I'm cumming!" I moaned, feeling myself reach that familiar peak as I continued rubbing my clit hard and fast. And then the release, which sent me writhing and bucking on the mattress.
I struggled to keep my eyes open and on Chris, watching and waiting as he resumed stroking hard and fast. Almost instantly, he was shooting his first load all over the window as he watched me cum. "He's cumming now," I told Mark. "Shooting all over the window again."
"That's so hot. You're so hot, Sam," Mark said, breathing harder. "I'm getting close, too. Thinking about watching you suck him. Touching yourself, knowing how much it would turn you on to have his big cock in your mouth like that."
By the time I looked back at the video, the guy was cumming in the woman's mouth a third time, an even bigger load than the first two. A big drop of the thick, white cum slid right down his cock and balls, then dripped onto the chair. I felt my pussy twitch again, looking back over to Chris to see him still hard and stroking, as the woman in the video kept sucking the guy's cock.
Then I tuned into Mark's words. The thought of him being there too, knowing he was watching me suck Chris' cock, making him cum again and again, was bringing me close to the edge again already. "I want that so much," I admitted. "I want you there watching me suck his cock. I want you to watch him fuck me. To see his huge cock disappearing into my pussy as he stretches me. Filling me."
"Yes," Mark breathed. "Letting him use my slut. Your slutty mouth and pussy."
"Oh god," I moaned. I slid my fingers inside my pussy for a few thrusts, then rubbed the wetness around my pussy, and onto my clit.
"He's going to cum a fourth time," Mark predicted as the video neared its end. "I want you to cum again when he does."
"Fuck..."
"Cum again for me. Cum for Chris. Cum thinking about his big cock filling your mouth."
"Oh my god," I breathed.
This load was the biggest yet. The guy's cock twitched and pulsed as thick streams of cum oozed from her mouth and slid down his still-hard length. She licked the tip of his cock like a melting popsicle, leaving him twitching and covered in his own cum.
"Fuck, I can't hold it! Cumming!" Mark groaned suddenly.
