"Hurry up!" Beth exclaimed, peeking out her bedroom door. "They just opened the front door!"
Behind her, Beth's boyfriend, Kevin, was hurriedly jerking himself as Penny sucked and licked his cock head. Penny teased his swinging balls with her fingertips and Kevin suddenly exploded. A fountain of cum splashed across Penny's face, dripping down over her exposed, D-cup breasts and their hard as steel pink nipples. He effectively coated her with warm jizz, then squeezed out a few last drops and wiped them across her offered tongue.
"Kevin?" came a demanding voice from downstairs.
Beth looked to them in alarm. "Kevin! Get down there!" she whispered fiercely.
Quickly but reluctantly, Kevin zipped up, tucked in his shirt, gave Beth a quick little tongue kiss, then the two of them rushed out the bedroom door.
Alone, Penny lay back on the bed, letting the cum ooze down her face.
The farewell hadn't gone exactly as planned. Kevin and Beth had been exclusively dating since early high school. Though both were 18, Beth was now nearing the end of her first semester of her senior year, but Kevin was in his first year of college several hours away. Products of strict upbringings, the pair had never more than kissed until just the last week, when they found a willing friend in Penny to help them along. The couple's parents had made sure Kevin and Beth never had a chance to go anywhere sexually, but when the teenagers met Penny at her job as a lingerie salesclerk in the mall, she found them the privacy and assistance they needed.
In the span of a week, Penny had helped turn two timid virgins into sex freaks. First she watched them give oral to each other for the first time in a store dressing room. Then she was asked to help Beth overcome her fear of sucking dick by sucking Kevin for her. There had been some ups and downs, especially when Penny found out Beth craved a man's cum as much as she did, but by now everything was worked out.
Unfortunately, Kevin's parents' anniversary, the reason he'd come back for a week, had come and gone, and now he was going back to school. Beth and Kevin had decided to break up after being released sexually, opting to test the waters elsewhere since they would be too far apart to do it together. They left on good terms, but Penny now wondered where this left her. She had essentially been their coach for a week, present during the couple's first orgasms, first sucks and fucks. But now what?
She was in Beth's bedroom in Beth's parents' giant house. Beth's parents were out for the evening, but Kevin's parents had waited in the car in the driveway, giving their son and his girlfriend a mere 5 minutes to say goodbye. Fortunately Beth had been prepared for this, and had arranged Penny to get there just minutes before Kevin and his folks had. That gave them about five minutes for Beth to suck her guy one more time, and, to show his appreciation for her help, allow Kevin to give Penny one final dose of the stuff she loved.
But Kevin's parents had grown impatient. They began honking the horn after three minutes, then one of them had come in through the front door downstairs. Beth and Kevin had to go say goodbye as Penny waited in silence upstairs.
Penny's mind was spinning.
One two occasions during the last week, Penny had found herself in very unfamiliar territory. When she sucked Kevin for the first time and he came in her mouth, Beth forcefully kissed Penny to swap the cum away, then licked the droplets off of Penny's face and breasts. Later, when Beth had taken a mouthful from Kevin, Penny fought back and swapped the cum away from Beth. Penny wasn't absolutely sure about Beth, but she knew that she, herself, was not a lesbian or even bi. She had never found herself curious about women. But those two incidents with Beth, added to all the things she had seen the beautiful young girl do over the last few days, was making Penny wonder how well she really knew herself.
And now, with Kevin out of the picture, did that mean the end of the relationship altogether, or would Penny find out just how close Beth wanted to be.
The idea of being with a woman still felt terribly wrong to Penny. She knew she liked men and always would. But Beth was so damn hard to get out of her mind, especially the feel of her hot little tongue and soft, smooth skin. Kissing her hadn't been better than kissing man, but it was still arousing as hell. Of course, there was always a man involved; always cum. Maybe it was really the cum that turned Penny on, and Beth was just a distraction.
Penny hoped that was it. She didn't want to be bi or gay. She didn't want to be with a woman. That would have made things so much more complicated, she thought.
And yet, when she could have licked herself clean of Kevin's facial, she just let the cum be, waiting for Beth to come back, anticipating the feeling of Beth licking it off of her. She wondered if Beth felt the same urges.
"I thought you would have cleaned yourself up and dressed already," Beth said, apparently in the room, though Penny couldn't see her because she was on her back, eyes on the ceiling.
Penny didn't know what to say. "Um, I, I just thought you might have wanted Kevin's last batch..."
"No," Beth said, sitting on the bed next to her. "I told you, I swallowed a load earlier today. That cum was supposed to be your gift, Penny."
"Oh," Penny said, pretending to have just remembered. "I guess I should have swallowed it, then."
"Yeah," Beth said. "I wondered why you took it on the face." She leaned over Penny, looking her face over. "God, you've got it everywhere." She laughed. "Do you want some help getting it off?"
Penny hesitated, then, "Yeah..."
Beth grabbed a handful of Kleen-ex from the nightstand. "It's a shame to put it to waste."
Penny grabbed Beth's hand and stopped her. "No, don't waste it...You can have some...if you want..."
