After your house party...it was your sister.

Kneeling on Ellen's dorm bed between her spread legs, you run your lips along her thigh again. Ellen's dildo lies to one side where you've freshly licked off Amy's juices.

Ellen sighs. Her hand settles in your hair.

"Here's how it happened," she begins. "That night you had that big party, you know I got pretty trashed. I kind of remember you carrying me off upstairs and laying me on a bed and squeezing my nipples, but that's about it for a while."

You feel a pang of shame at being caught, but manage to keep kissing smoothly up her upper thigh. You hmmm and nod an affirmative, breathing softly into Ellen's golden bush and inhaling her sweet woman scent.

"Mmm, that feels good. Slow like that," Ellen says. Her legs tremble under your fingertips. "I woke up still drunk and very thirsty, but a little sick to my stomach. I didn't really know where I was, so I got up and went to the upstairs hall. It was dark and pretty quiet. I guess the party was over and you'd gone to bed. But there was one light on at the end of the hall and I could hear girls talking and laughing."

You blow your warm breath into Ellen's pussy and make little circles with your fingertips, creeping up her inner thighs until the hairs of her bush tickle them and they rest against the soft ridges of her outer lips.

"Oh yeah," Ellen says. "Yeah. I couldn't find the bathroom so I went over toward the door to ask, but Cindy Butts came out first."

Cindy was one of your sister's friends, a big blonde girl who got pink instead of tan in the summer sun. Boys teased her because of her name and because she was kind of heavy, but she had a letter in swimming and volleyball. Her warmth and loyalty to her friends helped make her one of the more popular girls despite her deficits in conventional prettiness, family money and clique instincts. Or maybe it was her big car. More than once you'd piled into the back and headed out someplace fun.

Your fingertips lightly massage Ellen's outer pussy lips, and you kiss the center of her golden-fleeced mound.

"Mmm," Ellen says. She continues, "Cindy told me I was drunk as a skunk and helped me to the bathroom. She wiped my face and stuck around to make sure I was OK and after I peed and had a drink of water, I felt a lot better. Then she took her own turn to pee. I giggled because I was still feeling unsteady and didn't want to step back out in the dark hall but she told me not to worry about it. It was only when she stood up and didn't pull up her panties that I noticed she'd come out of the room wearing only a big T-shirt."

You curl the tip of your tongue and plow it lightly through Ellen's golden fleece, tickling her without touching her skin. As you press with your fingertips on her outer lips, you start hearing the soft squishing sounds of her inner wetness rising.

She giggles with pleasure. "Ooh!" she says. "Anyway Cindy told me to come on back to the slumber party, she'd keep an eye on me. But when we got back to the room -- your sister's bedroom -- there was your sister making out, I mean like really tongue kissing and squeezing titties and stuff, with Daphne Hollis. Cindy sat down on the floor and started brushing out her hair, but I just stood there in shock. But Cindy sat me down and started brushing out my hair -- I remember there were a couple sticky bits -- until it started feelng good."

You flinch internally, recalling your part in providing the sticky white drops in her hair. But you don't let that stop you. You owe Ellen big, and she owes you the story. You lick gently up her outer lips, right then left, pressing them gently together with your fingertips. Thinking of Ellen's story, you recall Daphne Hollis as a petite, bookish brunette without much presence. You never saw her around much, or thought of her as one of your sister's friends, so you're surprised she was even around that night.

Ellen said, "So there I was with Cindy brushing out my hair. I couldn't help watching Daphne and your sister just eating each other up. I mean I had no idea. And Cindy wasn't making any fuss. So it must have been a while but I kind of felt like I blinked, and there was Daphne taking off your sister's shirt and laying her on her back, and taking no time from Daphne sucking her nipples -- I remember her face, that curled lip, that frown, but it must have felt good -- I mean, no time until Daphne's head was between her legs."

Your cock throbs. You had no idea either. You'd thought your sister was devoted to study, sports, popularity, and boys in that order. But in a flash you can imagine your sister with her knees up, Daphne Hollis crouched between her legs with her head nodding and tilting. You've seen your sister frown and close her eyes with the impact of something she's been waiting for that she really loves -- her favorite song, the first bite of an ice cream -- so you know Ellen must not be making it up.

You stroke your fingertips down Ellen's inner thighs to the top of her silky stockings, and take the first taste of her inner juices. Wonderful. Salt-sweet, almost a little lemony.

"Oh yes," Ellen says. "Oh yes. Yes, that night, I was drunk and silly and surprised. I just went right over to Daphne and your sister and asked, 'Are you really eating her out?' Daphne sat up, cool as can be and said 'What do you think, Ellen?' We stared into each other's eyes for a second. Then she leaned over and kissed me. I was too stunned to do anything. She stuck out her tongue and I tasted your sister. It felt really strange. But it was...it was good."

You flick your tongue left and right, opening her labia, wet and salty and sweet.

Ellen sighs with pleasure and hums as you continue.

You've heard writing the alphabet with your tongue is the thing to do now. Instead you start writing "E-l-l-e-n, E-l-l-e-n" in big loopy curves. She moans and trembles under you. You tickle her hooded, prominently erect clit. She shakes and moans, dangling on the brink.

You realize she's stopped telling her story, so you pause.

"Don't leave me hanging," Ellen pleads. "Please!"

"What happened next, Ellen?" you press. "Did you go any further?'
