Jessica feels ashamed

Britney pulls out your cock, slurping it out of her mouth. "Mmm, tasty." She presses her nose to your groin and inhales. "Ooooh," she moans, with a shudder. "How do you do it? You smell just intoxicating," she gushes. She gives you a big lick, starting at your inner thigh, finishing with her moving closer and sucking on a testicle.

"A good chef never gives up his secrets," you quip with a smile. You look over to Jessica to see her rubbing her clitoris. She notices you and jerks her hand away, blushing furiously.

"What's the matter, Jessica? You can play with yourself if you like."

Jessica looks very conflicted, and stammers, "But -- it's wrong! It's dirty, and you're here, and Britney is licking your, your --"

You take some pity on her, and then remember your earlier message to her. "Jessica, look at my cock."

"But --"

"Look at my cock, Jessica. Um, Britney, back up for a second." Britney moans and pouts as she backs away from your crotch, giving Jessica an unobstructed view. Jessica looks at your thick member, glistening with Britney's saliva. You see her start to relax. "Count to five," you tell her.

"One," Jessica started, hesitant but no longer conflicted. "Two. Three. Four, Five!" she says, now much more relaxed, and even bright-eyed, feeling very good from staring at you, naked and horny.

"Jessica, don't worry about masturbating while Britney and I have fun. It's okay to get turned on by it, and fingering your pussy is a good way to enjoy yourself."

Jessica still looks comfortable, but blushes and shakes her head. "But you guys are right here, I shouldn't play with myself while you guys are watching."

You chuckle at the absurdity of Jessica's shyness. "Okay, look. Kneel in front of me, Britney, but face Jessica. You can suck on my cock some more in a moment," you say, interrupting Britney before she objects.

When Britney is in front of you, you kneel down with her, making sure to push your hard-on against the small of her back. Britney gasps for a moment. You snake a hand in front of Britney's crotch, looking over her shoulder to a growing moist spot on her panties, and start rubbing there.

"John," Britney asks with a bit of anxiety. "What are ---"
"Sssh," you cut her off, "you said I can play with you tonight. Just be patient."

You rub slowly but firmly against the bottom of Britney's panties, causing her to gasp lightly a few times. "See," you tell Jessica, "if I can play with Britney's pussy, then it should be okay for you to play with your own pussy." You raise your hand to Britney's right breast, and squeeze it firmly. "It's okay. Give it a try."

Jessica's hand had already drifted towards her cunt as she watched you gently **** your sister, while she kneeled passively letting you play with her body. She brings her fingers down to the opening to her sex, and dipped them in.

"That's it," you encourage, lowering your hand back to Britney's waistband, snaking underneath, and reaching to her own moist opening. Britney took a deep and airy breath in and out as you proceeded to finger her, while Jessica used her slick fingers to rub her clit. "Just do whatever feels good, Jess."

You pull your hand out of Britney's panties, and stand back up. Britney turns to look up at you, with a dazed and slightly consternated expression, but licks her lips and inhales deeply as she looks towards your cock, which is as hard as ever.

You smile to her, and she smiles a little in return as she turns around again. "Fair's fair, John. But you don't get to play with my body any more until I've had a good, long suck at your cock, and some of your fine side-offerings." She takes your cockhead into her mouth, swirls around it with her tougue, causing it to throb. She pulls it out of her mouth with a smack. "Deal?" she says, croutching to lick you slowly from your balls to your tip.

Just a few feet away, Jessica moans as she plunges her fingers into her cunt.
