With the house to myself after the twins left with a friend, I could do anything I wanted. I thought about the sisters that I had met last night in the hot-tub. I anticipated that there would be more of that. I decided to finish my homework for the weekend and be free of that hanging over me.
An hour later, I heard a strange tapping noise from my bedroom. It got my attention and I listened to hear where it was coming from. It didn't sound like a knock on the front door or the back door. The tapping came again. Maybe it's a woodpecker pecking on the side of the house. That didn't seem right either. The tapping came again but louder and more taps.
I got out of bed to investigate. I grabbed my robe off the back of the door and was in the process of pulling it over my naked body when I saw the source of the tapping. Sarah and Sandy were standing in our picture window that looks into the backyard. Sarah was rapping her knuckles on the window pane as she had her face pressed to the glass so she could see inside. Sandy was beside her with her back to the window. I guess she was making sure no one saw them. Sarah grinned when she saw that I was naked and in the process of pulling my robe on. I pointed at the backdoor and headed that way.
I opened the door and the two of them slid quickly through the gap before I had the door fully opened. They wore tight tee-shirts with no bras. Their nipples pushed on the cotton material. They had cut-off jean shorts and gleaming white sneakers. Their hair was down and it hung well past their shoulders to the small of their backs. Their erect nipples had the expected effect on my dick and I didn't even realize that it had lifted and was poking through the gap of my robe until their eyes went wide and they put their hands to their mouths and snickered. I grabbed my robe and pulled it together but there was nothing to be done about the tent in my robe.
"What's up?" I said.
Sarah and Sandy giggled and Sarah pointed at my crotch and said, "It looks like that's up." Sandy burst out laughing and Sarah gave an elbow to Sandy's ribs. Sandy elbowed her back, knocking her against the closed door. Angry looks flashed back and forth between the two of them for only moments and then Sandy began caressing her left nipple with her right hand. I doubt that she even realized that she was doing it.
Several moments of silence passed between us and it was clearly making them uncomfortable. Finally, Sarah stumbled out a sentence to break it. "Ummm... ummmm. We are actually here ... ummm ... for that." She pointed at the tent in my robe. She was rocking nervously from foot to foot as she spoke. Sandy just nodded vigorously when Sarah finished and pointed at my tented robe too. I let more silence fill the room. I wanted more information about what they wanted with my cock and I just wanted to mess with them a little.
After nearly a minute, I pulled my robe apart and let my erection bounce upward and point directly at their wide-eyed faces. The girls turned to each other and Sandy whispered, "Fuck. It's huge. We have to get a couple of selfies. Those snooty bitches would never believe us without the selfies."
Sarah giggled and turned back to me. She spoke to my bouncing cock rather than my face as she said, "Well. Ummm ... We wanted to take some selfies of us with your big dick. We won't get your face. We just want to have some proof to show the class princess and her court. They would just say we made last night up just to make ourselves look woke." Sandy just nodded. She was fiddling with her nipples again. Sarah saw her doing that and swatted Sandy's hand away from her tits.
I got the gist of their request but I wasn't pleased that they planned to blab our hot-tub session around their high school just to make themselves look more 'woke'. I got it though. High School life sucks when you're on the outside of cliques like the class princess and her court. I had experienced it not very long ago. I said, "What's your plan? Just take cell-phone photos of my erection to show the princess?" Sarah grinned and nodded and pulled her cell-phone from her pocket. Sandy followed suit and showed me her cell-phone.
I grinned at them and continued, "If your intent is to brag about how big the dick was that you had sex with, you'd need to put something in the shot for comparison."
Sandy said, "You mean like a ruler or something?"
I smiled and said, "That would work, but then the princess would just say that you downloaded the photos off a porn site."
Sarah's eyes widened like she had an idea. She looked at Sandy and they had that twin's communication thing going on. She turned back to me and said, "What if we took selfies of ourselves kissing your dick? That would be proof, huh?"
I smiled and said, "That would be undeniable proof." Sandy took my hand and pulled me into the living room and Sandy took several shots of Sarah with her lips pressed to my knob.
They got together to review the shots and then Sarah said, "This won't work. These pictures look like I kissed a big dildo. We have to get Dex's hips in the shot and take some shots to show how big it is and then show us sucking it into our mouths. Sandy was on board with that plan and we all moved into position. Sandy took pictures while Sarah first kissed my knob and then pushed her lips on and slowly pushed about a third of my cock into her mouth. She gripped the base near my balls. Sandy said that she was going to switch to video and Sarah began her blow-job as she looked at the camera. Sandy giggled and said that she wanted her turn.
Sarah was reluctant to stop her blow-job and so was I. They switch positions and Sandy kissed my knob while Sarah clicked off pictures. Then Sandy pushed onto my cock and struggled to get further down my shaft. Tears burst out on her cheeks and she gagged a little but quickly recovered. Sarah was clicking away. Then Sarah told us she was going to video and Sandy began her blow-job while Sarah filmed. After a minute Sarah lowered the cell-phone and said, "I think we've got what we came for." Sandy kept right on sucking my cock.
Sandy pulled back and licked her lips and looked up at me and said, "Fuck my face?" I smiled down at her as she pushed her lips back on. She pulled my hands up to the sides of her head and I started gently face-fucking her. Sarah raised her cell-phone and started filming again.
Sarah got some close-up shots and then said, "Come on Sandy. We'd better get home before Mom and Dad get back from grocery shopping. I continued the face-fuck making sure I didn't push to much cock in her mouth.
Sandy pulled back against my hands and I let her go. She pulled off my cock and said, "We should have some pictures with Dex's cum on our faces. That would shut the princess-bitch up." Sarah was reluctant to stay any longer but she eagerly nodded and Sandy went back to work on my cock. Sarah moved down beside her sister and I pulled my cock from Sandy and let Sarah push her way down my shaft. I was getting close to cumming as I moved back and forth between them. As I got closer, I took the cell phone from Sarah to get a bird's-eye view of them sucking my cock. I warned them when I couldn't hold back anymore and Sarah pulled her face back beside Sandy's with her tongue out like she'd apparently seen on porno sites. Sandy did the same and grabbed my cock and began furiously jerking on it. I blew my wad of long pearly white streams in a half-dozen installment onto their hair and down over their faces. I aimed the shots so both of them got an even share. I aimed for their open mouths and they received it before pushing it out on their lips. I was in the throes of my orgasm and my hips flew forward in a subconscious effort to launch my jizz as far as I could. They were covered and I got it all on video.
When we were done. I took a few still shots of them side-by-side covered in cum. They should have enough to satisfy the princess-bitch and her court. Sarah started licking the cum from Sandy's face and I started filming again. Sandy did the same for Sarah and then the got up and went to the kitchen sink to wash off the sticky residue. I closed up my robe over my softening dick and synched the belt.
Sarah and Sandy came over to me and kissed me on the lips and thanked me for helping them out. I said that the pleasure was all mine and it was. They scanned the backyard through the rear door windows and then made a run for the hedges where they had disappeared last night.
I sat down on the couch and thought, 'Well, that was an interesting hour,' as I lazily stroked my semi-erect dick. Then my mind turned to the upcoming afternoon.
As I was getting ready to go, I wondered if I should jerk-off so I could last longer with a group of horny women; at least that was what I thought might happen. I decided that the morning ejaculation in Sarah's and Sandy's faces would be good enough.
As I drove into Molly's driveway, she came running out and said, "Good, you're early. Park your car on the street. Okay?" I did as she requested although I didn't understand why. Molly hurried me into the garage through the side door that she had come out through. She immediately put her index finger to her lips as a sign to be quiet. I was quiet as instructed. Molly eased open the door from the garage to the house and pushed her head inside to see if the coast was clear. She motioned for me to follow her and she went quickly through the downstairs and up to her room. I caught a flash of her mother in the kitchen as I hurried behind Molly.
