Chapter 10

"Look what I bought." Abigail came bounding down the stairs into her parents' family room. Allison was reclining in an overstuffed chair flipping through a magazine. She had been waiting for her sister to arrive for their usual midday rendezvous, but Abigail was late. Allison let out a frustrated breath. Abigail was never late for these meetings.

They'd worked out a nice system over the last couple of months. Abigail would come over after Allison got home from school, usually about 3:30. Their brothers were doing spring weight lifting and wouldn't be home until 6:00. Neither would their parents, who were working. Jack had class until 5:00. That meant a nice quickie for the two sisters.

They also worked Jack nicely into their system. Allison just kept hands off when Abigail was home during the evenings. However, Abigail tried to pick up at least one evening shift a week to both earn more money and give her sister and husband some time together. The system seemed to fit nicely.

"Where have you been?" she snapped. "You're late."

"Whine, whine," Abigail answered back merrily. She tossed a bag on Allison's lap and began to take off her coat. "I've been shopping."

"What is it?"

"Open it up and see."

Allison opened the bag and looked in. She glanced up at Abigail, eyebrow raised, and then looked back into the bag. She reached in and pulled out a box. It was very clear from the picture on the box what was inside. Allison's jaw dropped and she turned a deep shade of crimson. "Abigail! You are such a little perv!"

Abigail grinned a devilish grin. "I knew you'd like it." She quickly pulled off her sweater. Allison watched, the lust growing in her belly. Abigail's black lacy bra seemed such a contrast to her pale skin. Allison swallowed.

"Um, I've never tried one of these," Allison confessed.

"Neither have I. But there is no time like the present." Abigail was wiggling out of her pants. "Doesn't work if only one of us is naked, though. Strip it, girl."

Allison stood up and followed her sister's lead. "Sounds good."

When they were both naked, Abigail picked up the box and quickly tore in, pulling the rubber covered dildo from the packaging. It flopped around in her hand. She began to lick one end of the red phallus seductively. "One side for you," she cooed, then licked the other side. "And one side for me."

Allison giggled. "You really are a perv." She bounced over to her sister and soon they were locked in a passionate embrace, mouths and hands exploring. Allison slipped her hand down to her sister's sex and slid a finger between the lips.

Abigail took a moment for a breath. "Oh, god, Allison. Who's the perv, huh?" Allison responded by pulling Abigail to the floor on top of her. Their bodies easily moved into position, each with a leg firmly planted between the other girl's legs. Allison body quivered as her wet labia soaked Abigail's upper thigh. Abigail repositioned herself and Allison let out a gasp. She could feel Abigail's bush brush against her own. She held her hips still while Abigail worked to make contact. Allison closed her eyes and exhaled again when she felt Abigail's swollen clit brush her own and then slip between her lips.

Allison joined the motion and began to buck her hips up at her sister. "Fuck me, Abbie. Fuck me with your clit." Little jolts of pleasure pulsed through her abdomen as Abigail's clit moved in and out of her lips. She felt the rough hair of Abigail's bush stimulated her womanhood.

The two sisters ground their pussies together, moaning and panting as they fucked. Allison's mind was bombarded with flashes of light, as it always was when she was lost in the throes of pleasure.

Abigail broke the contact and Allison murmured a protest. Her older sister grabbed the dildo and smiled down at Allison. Allison bit her lip as Abigail rubbed the head against her wet cunt. Then she pushed the head into Allison's tight little pussy.

"Unngh ... God, that's fat," Allison whimpered. She pulled her legs apart as far as possible and moved her hips, trying to get the whole head inside her. When Abigail stopped pushing, Allison relaxed her muscles and panted. "That is so tight."

"Does it hurt?" Abigail asked gently.

"No. Just tight."

"OK, then. Are you ready for me?" Abigail asked, giving her sister a little clit-flick with her finger. Allison jumped a little and tried to slap her hand away.

Abigail lay down opposite of Allison, her legs under her sister's. She scooted in closer, her cunt only a few inches from Allison's. Allison was fascinated.

"Have you ever realized how similar our pussies are?" she asked Abigail.

Abigail was concentrating on lubricating her end of the dildo with her pussy. "Huh?"

"Our pussies. They look a lot alike, they taste a lot alike. You can definitely tell we're sisters. Oh shit..." Allison let her head and shoulders drop back to the floor as Abigail shoved the cock into her own cunt. The action pushed Allison's end deeper and sent a jolt through her.

Soon, the two girls were grinding again, this time working the fat cock between their legs. Abigail sat up part way and gripped the middle and began to shove it in and out of their cunts.

"Ohh, fuck, Abbie ... Ohmigod. Don't stop."

"I ... won't ... oh damn that's good. You look so hot, sis."

Allison was pushing up to meet Abigail's thrusts. She pinched her nipples, tugging and pulling and enjoying the sensations weaving through her.

Abigail sat up and moved over Allison, straddling her sister. The dildo popped out of Abigail's cunt. She giggled and reached between their bodies to replace it, taking the opportunity to flick her sister's throbbing bud again.

Allison jerked and glared at her sister. "Stop that, bitch." They both laughed and then Abigail leaned forward, crushing their breasts between them. Mouths met again in frenzied exploration. Allison felt Abigail's peaked nipples stab her own. "Oh ... my ... god..."

Allison moved her hand between them now and found the middle of the cock. She held it still and Abigail began to ride her pussy on it. Each drop of her lover's body impaled the thick shaft deeper into Allison's cunt. She felt like she was going to split open, but even the tiny ache in her walls sent waves of pleasure through her. Their mouths were frantic as Allison fucked her sister's pussy. Now Abigail was grunting and groaning, moving sporadically.

"Uungh ... Oh yeah ... Fuck me, Allie!" Suddenly, Abigail's full weight crushed Allison as she went into convulsions. Abigail's hips bucked and thrusted. "Oh, shit ... I'm coming... !"

Seeing her sister's release, feeling the cock in her hole and Abigail's body writhing on her was too much for Allison. Her pussy began to convulse, sending waves outward. "Oh, fuck ... Oooh, Abbieeee!" The waves coursed through her and she shoved her tongue into Abigail's mouth, muffling their moans. The girls kissed through the climax and descent, then lay completely still, their lips pressed, but not kissing.

"Abigail," Allison finally forced out between their lips.

"Whatchawant, baby?" Abigail slurred.

"I can't breathe."

"Oh!" Abigail quickly raised off her sister, her pussy releasing the dildo with a slurp. "Oh, baby, I'm sorry!"

Allison took a deep breath. "It's OK. I'm good now." She let her head roll over to the side to look at her sister. "Thanks for the toy. That was awesome!"

Abigail smiled and looked down at Allison's pussy, her legs splayed and the dildo hanging crudely out of her lips. "I think you need to give it back now." She reached down and pulled the cock free, sending a post orgasmic quiver through her sister.

"Girl, you are mean. So mean," Allison said, grinning. "I get to keep that, right? I mean you have a cock whenever you want." Abigail lay down beside Allison and began her customary drawing on the younger girl's belly. Her face contemplative.

"Allison, can we talk seriously for a minute?"

Allison tried to read her sister's eyes. "Sure, Abbie. Take it away."

"I think we need to tell Jack about us. I mean, he's been completely forthcoming now with me, and I don't think it's fair to keep our secret away from him."

"You sure?"

Abigail took a deep breath. "Yeah. I'm sure. I can't stand being hypocritical."

Allison continued to watch Abigail. She trusted her older sister implicitly, but she could tell there was more. "And?"

"What do you mean, 'and'?"

"There's something else you aren't telling me. Some other reason why you want to come clean."

Abigail continued to avoid eye contact. Allison could see her mouth working, as if trying to form the words. "Well, I ... I guess I'm starting to get a little jealous."

Allison was surprised and concerned by this revelation. Abigail had never said anything before, and Allison wasn't getting any vibes that something was wrong. This was the obvious concern in the backs of everyone's minds. She had a passing thought as to how confessing their relationship eased any jealousy, but she didn't go there.

"Abigail, are you saying you want me and Jack to end our relationship?"

"No. No, I don't want that. It's just..."

"We only see each other about once a week now as it is." Allison could feel her hackles begin to rise. "Anything less will practically be nothing at all."
