Mouth.

"Sure, just use your...mouth. I'll tell you what feels good. That's another lesson right there." You say, lifting your hand to cup her cheek, you run your thumb across her lips as she does so. You smile as her tongue flicks out to lick your thumb. "Always listen to how your partner reacts. Physically and vocally. They can't help but moan when it feels good."

"You would have made a great teacher, Alex" Cassie replies then moves in to kiss you on the lips.

After a five second tongue kiss she moves down to your breasts and hoovers your right nipple. "Oh yeah...that feels good how'd you learn that one?"

"While I was masturbating I had one hand on tickling my nipples and...well it felt good and I though I'd try it on you. Just with my mouth." She answers, then starts trailing her tongue down your taut and spasming stomach (Hey, it tickled, alright?). You feel her hand trail up your leg as you lift the blanket covering you to let her under.

Finally her tongue leave your skin right at your pubic bone for a second as she changes position to between your legs. You see her head lift up, and then she says, "Hey...could you, like...lift the blanket a second to let more light in? I...I want to see what your pussy looks like...please?"

You chuckle gently, "So polite." You lift the blanket and grab the camping light to get it closer. You look down and see Cassie's head hovering close to your wet opening, her nose flaring as she gets whiff after whiff of you scent. Her eyes meet yours and she smiles happily.

"You are so nice." She says, "And beautiful. Everything about you..." Keeping her eyes on you she flicks her tongue across your exposed clit. You almost drop the camping lantern at the shot of pleasure running through your body. To forestall a bad situation you lean over and put the light out of easy reach and then lay back to play with your breasts as Cassie starts sucking and licking you out with earnest.

Her arms wrap around your legs and she mashes her face into your nether regions as she attempts to fuck you with her tongue, trying to get her tongue up to reach your... 'oh ...She has a long tongue' you think to yourself as the tip of her tongue brushes your G-spot. "Oh...so good." You say aloud, encouraging her.

You feel her lips form a seal around your clit, and then she starts sucking. Slurping sounds are heard when the vacuum she creates becomes a little too much for her to keep her lips sealed. But the feelings running through you. The girl definitely was attentive to a partners pleasure. Every time you moan she spends a little more time doing that, and then moves on...but she remembers what makes you moan as every now and then she'd return to that spot. One of the biggest pet peeves you ever had was guys who';d find something you liked...and then beat that nerve ending to the ground numbing that nerve ending of it's pleasure sensors and moving right on up to actually annoying you. You had to rip many a guys head away from your pussy to tell him to just fuck you so he could come and get the fuck on out. Not that you had that many partners, but...you had to do that to a good seventy percent of them easy.

You feel her fingers digging into the soft flesh around your hip bones as she tries to bury her head into your pussy, seemingly addicted to your juices now as she licked up and down your slit, buried her tongue in you, and sucked all she could down her throat.

Finally you can't take any more and cum hard flooding the girls mouth with your juices. You scream, no control whatsoever.

You hear Ritter laughing as you come down from your orgasm, Cassie is now crawling up your body. She gets face to face above you, her hard nipples brushing yours as she smiles at you tentatively, "Was...Was I good? Cuz you taste good and I want to do that again. I came twice making you cum!"

You reach up and pull her head to you, shoving your tongue into her mouth. You feel her sparse bush on your mound as she grinds into your mound. You think she has a small orgasm from the kiss before you let go. "You were great, Cassie. You really were. And I'd like to do that again, but we have a big day ahead...let's get some sleep."

You expect her to roll over and get into her own side, but instead she just nods and lays down on top of you. You wrap your arms around her as an older sister might to protect a younger sister from a storm, and drift off to sleep.
