Stacy, his sister’s best friend

It was several days after his experience with Kelly and Rob still had no idea how to ‘lay it forward’. He had already been slapped down for propositioning the mum of a friend of his – who it turned out wasn’t that **** after all. He really wanted to make Kelly’s ‘lay it forward’ idea work. He wasn’t sure why. After all, he could just accept the free blowjob and move on with his life. She would never know. But somehow he felt obligated to lay it forward. Maybe that was the strength of the idea.

Then one evening, returning home to another microwave special left by his absent parents, he was greeted by the sight of his sister and her giggling friend Stacy.

“Hello, Rob!” they chorused, teasingly.

“Where’s mum and dad?” asked Rob.

“Out tlll 10,” answered his sister. “We’ve got you to ourselves again.”

“Yeah, we can have a threesome,” taunted Stacy.

“Ewww, gross! He’s my brother,” squealed Rob’s sister.

“Ooh, then can I have him to myself?” laughed Stacy. Rob had never really taken Stacy and her taunting seriously. She was a loud, clumsy, horse-faced girl who had made his life a misery forever with her teasing. And, even at eighteen, she didn’t look like she was blossoming any time soon. She still didn’t have a boyfriend. A bit of a hopeless case really.

With that thought, the cogs in Rob’ brain started whirring.

“Hey look at this,” said his sister, breaking in on Rob’s reverie. Rob looked up.

“Get up, Stacy,” continued his sister.

“Why?” her friend asked warily.

“Just do it,” hissed Rob’s sister.

Stacy got clumsily to her feet, whereupon Rob’s sister grabbed her friend’s short clingy dress by the waist and yanked it upwards, revealing Stacy’s hairy snatch, entirely unprotected by panties.

“Ooh!! You bitch!!” shrieked Stacy, trying to tug down the hem of her skirt.

“Look. She’s waiting for you Rob,” his sister taunted, pinning back her friend’s arms and keeping the dress above Stacy’s waist.

“Okay,” said Rob at last. “If you want me to fuck you, Stacy, I will.”

The girls went silent. Then Rob’s sister said:

“Will you do her here? On the living room floor?”

“No, I’ll do her in my bedroom, out of the way of your prying eyes. But there is a condition.”

“What’s that?” asked his sister. Unusually, Stacy remained silent.

Rob explained to them about lay it forward.

“You want me to fuck you and three other blokes?” demanded Stacy at last. “What do you think I am? Some kind of slut?!”

“Dude, you just flashed your pussy at me in my living room. I think we know exactly what you are. Take it or leave it.”

“Take it!” hissed his sister conspiratorially. Rob lay back into the nearest chair and relaxed. This lay it forward stuff was pretty liberating, he reflected. If it worked out, he would get sex. If it didn’t… well it was only Stacy.

“Are you going to suck her tits, Rob?” asked his sister. Stacy broke into nervous laughter again.

“If she wants,” answered Rob casually.

“Are you going to eat her cunt then?” continued his sister. Stacy held her breath.

“If she would like me to,” answered Rob, magnanimously.

“I’m not going to suck his cock,” cried Stacy loudly.

“You don’t have to,” said Rob calmly. “I’m doing you, remember?”

“Alright. But this better not be a trick.”

“Its not. Its ‘lay it forward’ remember?”

Rob got lazily to his feet and held out his hand.

“Coming?” he asked.

Stacy got warily to her feet, self-consciously tugging down the hem of her dress. Rob’s sister made to follow her.

“You stay here,” Rob commanded her. His sister pouted and sat down again.

Stacy followed Rob meekly up the stairs. She had not been in Rob’s room for years; since they were kids. It was messier than ever, plastered with even more heavy metal posters and only seemed to have evolved in that it had a bigger music system and a more expensive guitar in one corner. Rob carefully bolted the door and Stacy felt an irrational thrill of fear, even though she knew it was just to keep his sister out.

“Shall I get my dress off then?” Stacy asked casually.

“If you like,” said Rob, who really wasn’t used to this sort of thing.

Self-consciously, Stacy pulled the hem of her tightly fitting mini-dress up over her head and off. Graceful it was not, but Rob began to feel oddly excited. She stood before him, her chunky body naked, but for an incongruous greying bra, that covered her small breasts. She removed the bra a flopped onto Rob’s bed with her legs open. The girl had no class or subtlety, reflected Rob, but he felt himself growing hard nevertheless.

Cautiously, Rob knelt at the end of the bed. He’d watched enough porn to know that women appreciated a bit of foreplay before you stuck it in them and also, that it was all over once the man came. He moved his head between her thighs and began to lick at the fleshy lips beneath her hairy entrance. Stacy began murmuring happily almost immediately and Rob figured he’d done the right thing. He was also glad to find that – despite what people said about her – she did wash down there.

Rob began to lick all around her intimate area. When he found hr clitoris, she gave a little gasp of pleasure and he concentrated on that area from then on. Muff diving had two clear advantages as far as Rob could see: First of all, it pretty much guaranteed that she would come at least once before him – which he guessed was the idea behind ‘lay it forward’. Secondly, he didn’t have to look at her face.

Rob did however, glance up, over Stacy’s slightly rounded belly, to see that she was gasping and pinching at her nipples; transfixed with desire.

As her passion mounted, Stacy’s cries grew louder and Rob hoped he’d remembered to close the window. He had visions of his parents coming home early and hearing the racket as she came. Suddenly, she was bucking on the bed, crying out and clamping his head between her chunky thighs. Rob carried on licking s her orgasm ripped through her, until at last Stacy collapsed in exhaustion.

Rob got up. Undid his jeans and let them fall to the floor. Then he climbed onto Stacy’s perspiring body, slid inside her eager snatch and fucked her hard. For her part, Stacy eagerly wrapped her legs around him and urged Rob on. And she came again before he finally did, Rob was pleased to note.
