Dina makes Mark and Carol an offer they can't refuse.
She got to my desk first, since she'd been on top of me. It was Carol, home from her evening out and ready for a videochat. Dina clicked "connect," and Carol appeared on the screen. And Dina appeared on hers, naked.
I was so busted. "What the fuck..." I could see Carol saying.
"Don't log off," Dina typed. "I can explain."
"You can try."
"Okay, first of all, Mark and I just sucked each other off. He didn't break his promise to you. No fucking. And it was all my doing, so blame me. You hate me already, so that's okay."
"I think I might hate both of you right now."
"Carol, be realistic: I know you love Mark and he loves you, but you live hundreds of miles away from one another. You have no idea when you're going to see one another again, and eventually one of you is going to need a good fuck. You know it's true. Somebody's going to break the promise."
"I'm offering you a chance to at least watch Mark's first fuck. Be a part of it."
"What??" I said and I could see Carol mouthing the same word.
"Okay," Carol typed after a long pause. "How are we going to work this?"
Dina told me to lie back down with my head on my pillow, and positioned my laptop videocam so that Carol could see both of us and I could see her.
"Get naked," Dina typed. "Mark will be fucking me, but he's going to be thinking about you."
Carol hesitated, then began to undress. My cock might have deflated when she caught Dina and me naked, but watching her was getting me hard again.
"Now I want you to play with yourself. Get your pussy juices all over your fingers."
"WTF??? I'm not doing that in front of you."
"I have a reason. Trust me," Dina typed and she began playing with her own pussy. Carol started as well. I could hear the slurping sounds coming from Dina, and imagined they were coming from Carol.
When Dina's fingers were slick with her juices, she told me "Pretend this came from Carol's pussy," and rubbed them all over my cock. Carol saw what was happening, and started finger-fucking herself much harder, and smearing her own pussy juices all over her small breasts and hard nipples.
Dina straddled me, making sure Carol could see. "I hope some day you'll really get to fuck Carol," she said to me. "When you do, I'm guessing she'll really like this." She took my hard cock and brushed it against her clit. "Mmmm," she purred. "this thing's good for more than just fucking." she rubbed my cock hard against her clit, as if she were masturbating with it -- I guess that's exactly what she was doing -- and said "oh god, fuckfuckfuck, fuck!" She took a moment to catch her breath, and said "Okay, this dick of yours just gave its first orgasm to a girl. I'm good and ready to be given a second one."
"If your cock thinks it has pussy juice on it now, just wait until it sees how wet I am." She lifted her body, guided my cock to her pussy lips, and lowered herself down, taking just the head of my cock inside her at first.
It felt amazing, better than anything I'd imagined, better that oral sex which I'd thought was the greatest feeling possible. Dina lowered herself a little more, allowing me to impale her maybe another inch. I looked over at the computer monitor. Carol was fucking herself with.. a vibrator? I assumed it was a vibrator, I'd never seen one before, had no idea Carol even owned one. She was fucking herself very slowly. That was so hot.
Dina looked over to the screen to see what I was looking at. "Who'd have thought?' she said. "I wonder if she'll go faster if we do." and with that she pushed her body down, letting me fuck her with my entire cock. Then she started bouncing up and down quickly, her breasts swaying. It felt as if her pussy were contracting, sucking my cock deeper into it.
I looked over at the monitor. Carol was really into it now, using the sex toy to fuck herself harder and faster. She shook her head back and forth sideways, which I knew meant she was cumming, but she didn't stop fucking herself.
"Do it," Dina said.
