A little handshake (Warning: M/M content)

Hannah chuckled in her evil, mad-scientist tone. "Well, funny you should ask," she told Gavin. "Now that we all have our motors running, my next experiment will take it up a notch."

The cabin bedroom Zack and Gavin had taken to share with Chloe was warm with the late spring day. The atmosphere was sticky with sex, from two young men and a woman sweating together. Each of them had already had an orgasm on this bed, first Zack and Hannah together, then Gavin watching a spy video of them while they hid under the bed. The scent of Gavin's seed was a sweet, grassy undernote to the sexy funk.

The three of them sat side by side on the bed, Hannah in the middle, thighs pressed together.

"One of my favorite favorite things is watching cute guys touch themselves," Hannah said. "So. Zack. Gavin. Take hold of your dick. Yes. That's what I like to see." She smiled. "And both of you have real beauties. Trust me, I would know. Now is that your favorite hand?"

"Yes," Gavin said. Zack grunted agreement. Gavin favored his right hand. Zack used his left.

"Stroke yourself. Gently," Hannah said. "Yes." Her smile broadened to a grin. "That's beautiful. Gavin, you're getting hard like when you were watching me and Zacky here." Gavin moaned. "Hey, and Zack. You're getting hard like when you were watching me strap it on into Taylor."

"Uh," Zack said. Hannah had just laid it out there. But she'd left Heather out of it. Cheerleader solidarity?

Gavin gasped. "Yeah?"

"Dude," Zack said, trying to bat the thought away.

"Zack walked in on me fucking Taylor just like you walked in on me and Zack," Hannah said.

"Uhh," Gavin said.

Zack blushed and stopped stroking himself.

"I punished him by making him sit and watch," Hannah said. "Bad boy. Walked through a sock on the doorknob. But Zack was good. He sat and waited. So I rewarded him. Like you saw, Gavin."

"Uhhh," Zack and Gavin sighed together. Zack started stroking again.

"Easy, boys," Hannah said. "Actually I'd say it was a mutual reward."

Hannah, Zack thought. Hannah, Sexual Napalm. Shooting into her while she was coming hard on his cock.

Hannah! Gavin thought. Bucking under Zack's thrusts as they came together.

"God I love you guys," Hannah said. "You should see the expressions on your faces. Hell, just look at each other."

Zack and Gavin looked. Cheeks flushed, brows moist, lips parted, nostrils flared, breathing hard.

"Now you know what I like to see in a man," Hannah said. "Kiss me. First Zack."

Hannah turned her head. She cradled Zack's head and pressed her lips hard to his, parting her lips, nibbling his lips, running her tongue back and forth along them. "Mmmmhh," she sighed. "Now Gavin." Her touch was gentler, softer, her senses open to how Gavin was responding. She stroked a hand over his shoulders, soothing his tensely poised body. Gavin sighed. "That's right," Hannah said. "That's right."

She turned her head back to the center and circled Zack and Gavin with a hug as they sat in a row, thigh to thigh.

"Now," Hannah said. "Give me your hands."

She took Zack and Gavin's lube-slick favorite stroking hands and guided each to his friend's erect shaft, closing the fingers round with the pressure of her own hands.

"Oh," Zack said.

"Whoa." Gavin said. His cock swelled in Zack and Hannah's grasp. Zack's cock twitched, echoing Gavin's.

"No safeword?" Hannah teased.

Zack and Gavin looked at her, but nobody said anything.

"Now this is for me," Hannah said, holding her warm hands over Zack and Gavin's. "Remember? All for me."

Zack coughed to clear his throat and nodded. Gavin bobbed his head up and down.

"So let me get started," Hannah said.

Hannah moved her hands up and down, guiding Zack's hand on Gavin's shaft, guiding Gavin's hand on Zack's. She watched their faces and listened to their breath.

"Okay, boys, keep going," Hannah said. "For me." She opened her hands.

Zack and Gavin kept stroking each other, their arms crossing across Hannah's belly as they sat together. Their breaths came quietly through parted lips and flared nostrils. Now and then there was a little moan or sigh, nearly inaudible. Hannah laid her warm hands on Zack and Gavin's backs, crooning gently. "Yes. Yes. Yes, that's the way. Keep going."

Hannah watched closely. The boys were stroking each other slowly and steadily. Zack seemed to be holding up well. Gavin's bigger penis was twitching and weeping a bit. She could feel more tension in his back.
