"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. "don't wait. Fill Carol's pussy with your cum. I'm on the pill, so you don't have to worry. Pretend I'm Carol. Give it to me, fill me up, make me pregnant, make Carol pregnant, it's okay."
I groaned and spurted into Carol's pussy, into her womb -- I mean Dina's -- once, twice, three time, four times until I felt drained. I couldn't believe I could come that much, just minutes after Dina had sucked me off.
I could see Carol catching her breath after another big orgasm. She held her wet vibrator up to her computer's camcorder so I could see it.
Dina had come moments after I had. She rolled off of me, not as out of breath as Carol, but tired and contented.
She picked up her panties, wiped her hands clean on them the best she could, and typed on my keyboard, "Carol, we might not like one another, and I'm not sure how you feel about what just happened, but I'm going to figure out some way to get Mark over there to see you. You guys need to be together."
Carol took longer than she probably needed to cleaning her own hands, before she finally typed "Dina... you come too."
