Accepts Vanessa's advances

"Well," Cynthia says, "if your sanity's at risk..."
Her hand runs across Vanessa's back, her fingers brushing against her friend's skin. She's never been with a woman before. Back in college, she and Vanessa had kissed a few times for a laugh, and this is far from the first time she's seen Vanessa naked, but she never got the impression that Vanessa might want to go further. Unsure exactly how to start, she continues gently running her hand up and down Vanessa's back. Vanessa lifts her leg a little and re-positions herself ever so slightly so that her crotch is up against Cynthia's leg. Cynthia lets out a tiny gasp as she feels the wetness of Vanessa's pussy on her thigh. She feels Vanessa's hips begin to move slightly as the other woman grinds against her leg.
"You're really wet," Cynthia comments, not sure what else to say. In the scant light which enters the room between the curtains and under the door, she sees Vanessa smile.
"Are you gonna do something about it," Vanessa asks, "or just keep making me wetter?" I guess I'm really about to do this, thinks Cynthia. Still, it's daunting. She has no idea what she's meant to do.

"Okay, uh, turn around," Cynthia instructs. Vanessa complies and Cynthia lies behind her, spooning her. She reaches an arm around Vanessa's body. Her hand finds her breasts first, making Vanessa squeak as Cynthia plays with her nipple.
"Is that good?" Cynthia asks. She doesn't know what she's feeling right now. She's still incredibly angry at Vanessa, even hates her, but now that her arms are wrapped around the homewrecker's naked body, playing with her tits, all Cynthia can think is how much she doesn't want to embarrass herself. She wants to satisfy her.
"It's good," Vanessa says, rubbing her legs together slightly. Cynthia lifts her fingers to her own mouth and coats them in saliva before returning them to Vanessa's right nipple. She can tell that her friend wants more, but Cynthia's still working up the confidence to reach down between her legs.
"Lift up a bit, I want to get my other arm around you," she says. Vanessa complies and Cynthia slips her left arm around her body, fondling her breast. Vanessa's breath grow heavy over the next few minutes, so Cynthia figures she must be doing something right. Growing more confident, Cynthia slings a leg around Vanessa's thigh, drawing their bodies closer together. She feels powerful, in control, and without thinking starts moving her hips as though she's thrusting something into her friend. Vanessa seems to notice and enjoy this Cynthia's growing confidence. She's practically trembling with arousal, stifling little moans.
"Fuck, Cynthia," she finally gasps, "Stop teasing and touch me." Her voice is high and ****, like Mark when his arousal's been turned up.

Cynthia's right hand travels down Vanessa's belly until it finds the hot wetness of her pussy. She chose this position because it would be the most like masturbating - with their bodies lined up like this, it almost feels like rubbing her own clit instead of her friend's.Vanessa's clit is swollen and sensitive, and Vanessa gasps its slightest manipulation. As though she forgets where they are, Vanessa moans as she grinds herself against Cynthia's fingers. She sounds the way she did that first time Cynthia heard her fucking Mark.
"Sssshh," Cynthia whispers, "people will hear."
"Sorry," Vanessa breathes, but within a minute her moans are working their way up in volume again.
"Van! Fuck!" Cynthia hisses.
"Shit, sorry!" Vanessa gasps, "I just- oh, fuck. I'm really close." Cynthia grips her closer, burying her face into Vanessa's hair as she quickens her stroking on Vanessa's clit.
"Fuck! Yes! Like that!" Vanessa pants, "Make me cum!" With her other hand, Cynthia grips Vanessa's tit, squeezing it and rubbing the nipple with her thumb. Vanessa lets out a whine of pleasure, her body growing tense. Her legs begin to shake.
"I want you to cum for me," Cynthia breathes into Vanessa's ear. Vanessa lets out a cry and Cynthia feels her friend's clit throb as her orgasm begins. Cynthia tries to shush her, but it's no use - Vanessa gasps and moans as her orgasm washes over her. Cynthia keeps stroking, slowing her pace as Vanessa comes down. Finally, Cynthia removes her hand from her friend's crotch and flops onto her back, breathing heavily. Vanessa does the same, her face blissed-out and flushed. It's a minute before either of them speaks.
"I think I might need another shower," Vanessa admits.
