Encourage.

Beth decided to ramp things up. She sat herself on the ottoman in front of Kyle, legs spread, still rubbing, and began to egg him on.
"Come on, Kyle." She pumped the air with her free hand. "I want to see it. Stroke that big dick for me, baby." {if Formation = 1
} That's what the girl's in the porn videos say, right? {endif}
"You're the devil..." Kyle grimaced. He did start to stroke harder though.
"It's going to feel so good when you pop. I bet it's been a long time. You've got a lot stored up. I can tell." This is fun. And wrong. And so much fun.
"It has..." he was starting to relax a bit more, and was more openly enjoying the show she was putting on for him. The porno behind her was largely forgotten.
"No lady friends to keep you company, soldier?"
"None that looked as hot as you."
"Aww... you're sweet." Beth was blushing, she realized. Really? That's what makes you blush? Not EVERYTHING you're doing, but the compliment? "I want you to cum for me, Kyle. Can you do that for me, baby? Can you squeeze out all that pent up seed... for me?" Beth realized that she was very close to cumming herself.
"Fuck..." he was bucking his hips now with every pump, and he was making little whimpering moans. "Shit...I'm..."
"AHHH...." Beth's orgasm sneaked up on her, ripping through her body like a wave and coating her fingers in sticky juices. She could see that Kyle was about to pop. He's going to cum all over... There was no tissue or paper towel, or anything close by. "Go ahead, baby..." she whispered. "Cum for me..."
"Aw fff....." as he pumped furiously, she sprang into action. Can't let him make a mess. She leaped forward, covering the head of his cock with her lips before she could stop herself. Months of stored jizz rocketed into her mouth, and she wondered if she might orgasm again just from the sheer lewdness of it.
"What....the....fuck?!?" Kyle couldn't stop, though. He squeezed every last drop into her mouth, and when he had finished, she sat back against the ottoman, mouth open, showing him the lake of cream he had made.

"Goog... bouy...." she gargled.
"Why...why did you do that...?" Kyle was panting, and looking for his gym shorts, whiched had gotten lost in the excitement.
Beth swallowed, and then gave a little shake of her head. "I couldn't have you making a mess. That's just being sensible." Yum...
"Jesus..." Kyle had located his shorts, and was pulling them up. "Beth, we..."
Beth sighed. "I told you... we both needed to blow off some steam. We didn't do anything." Beth almost expected her nose to start growing at how much bullshit she was spinning. "Now that we have, maybe we can both get to sleep."
"OK, I guess..." Kyle didn't seem so sure that their activities were perfectly okay, but he seemed to content to let it lie. "Goodnight, then?"
"Good night." Beth was seized by an impulse, leaping up to plant a kiss on his lips. "Thanks for sticking up for me." she whispered, before darting away to silently climb the stairs and swish with some mouthwash before sneaking back into bed.
You're playing with fire...
It was fuuuunnn....
It was cheeeeeating....
No it wasn't! We just blew off....some steam.
She knew she couldn't lie to herself that well, but in any case, it was a one time thing. Wasn't it?

Sleep rolled over Beth.

Wasn't it?
