A wand.

She pulls out a magic wand, and Jenna laughs.
"Oh, baby... I love the way you think..."
"I've never used one before, but they're supposed to feel amazing..."
"Yeah...apparently, using one is a great way to..." she trails off, and Tara nods.
"Uh huh! Yeah! That's what I was thinking too!!!" Tara starts nodding. "I've done it a few times, but I can't seem to do it consistently."
"Well...what's a hotel room for, baby?" Jenna kisses Tara, grabbing her ass and pulling her tight.
"Hi!" you wave.
"Sorry, honey." Jenna breaks off, turning to favor you with a sultry smile. "All we're saying is...it's might get a little wet in here."
You smile. "Not a problem for me, honey. I'm not opposed to it, you know that." Jenna is an infrequent squirter. You've never been put off by it, in fact, you think it's pretty hot. Stupid people think it's just pee. You've had it in your mouth: it's not pee.
You pull a comfortable chair over to the bed. You're going to let the girls explore and enjoy for a while before joining in.
"...rechargeable one!" Jenna exclaims, looking over the sex toy.
"Yeah I figured it would be better..."
The girls enter from the outer room, talking about the toy and smiling. Jenna looks at you quzzically, and you raise your glass. "You two start...I'll join in. I want to watch first." Jenna gives you a loving smile.
"You hear that, little girl? That means your all mine for now!" Jenna pushes Tara onto the bed, and begins to attack her clothing. Tara is naked in no time, and Jenna is kissing and touching every inch of her with a fierce hunger. Her lady fever has a hold of her now, and you pull out your cock to rub while enjoying the show.

Jenna starts slow, kissing Tara's legs and mons before eating her out, sticking fingers into the young girl's mouth before fingering her. Jenna is deft and determined, watching Tara's face and adjusting according to her reactions.
"Ms...Ms. Jenna...you make me feel so...goood....."
"Just Jenna, baby girl."
"Jenna...." Tara reaches up to grab one of Jenna's tits through her dress. "Mmm..."
Jenna strips down to her lingerie, and grabs the wand. She presses it against Tara's clit, and holds it there while she slides next to the quivering girl, cradling her head and shoulders while she works.
"Focus on how good it feels..." she looks deep into Tara's eyes. It's so hot, and touching too. Tara isn't just a piece of ass, like Mia at the club. You think Jenna might just be in love with this little blonde thing. You stroke more earnestly, loosening your pants and shirt. Tara starts to moan loudly, opening her mouth wide, and Jenna nods, caressing Tara's lips with her own, though you don't know if you'd call it "kissing."
"Jenn....a...I think..."
"MMHMM!!" Jenna nods excitedly. "Let it out, Tara..."
"Aaaahhh!!!" a fountain of clear liquid sprays in a stream from Tara's pussy, and she shrieks with delight.
"Good girl! So quickly! You're a natural!"
"Mmmmff....." Tara moans. "Before...it's always happened from inside...that's the first...from just the clit..."
"It's a 'magic wand', girl." Jenna laughs.
Tara looks at Jenna with hunger. "Sit on my face, Jenna."
