"No..."

Beth couldn't understand why she couldn't tell him to stop. He was manhandling her like no one ever had before. And I like it. Emboldened by her silence, his hands had reached her tits, caressing her nipples through the thin lace of her bra. She whimpered involuntarily at the stimulation: her nipples were hard, and he could feel it.
"Do you... really...want to stop?"
"......no." It was a breathy whisper. Jeff tortured her erect nipples for a few seconds.
"What was that?"
"No." a louder whisper.
"No...?" He pinched her left nipple just hard enough to make her cry out a little. His left hand pushed up under the bottom of her bra, squeezing her right tit. Strong hands... She bit her lip. "No, what?"
"NO...I don't want you to stop..." she looked up at him through her eyelashes, and bit her lip.
"Good. Then let's get on with things."
Her shirt went onto the ground quickly. Her bra followed soon after, and while Jeff kissed her neck, her chest and then leaned down to suck on her tits, she fumbled at his shorts, feeling the impressive outline of his dick. She pushed her hands into his shorts, grabbing his member and stroking it while they kissed.
"You like my cock, huh Miss Wilson?" For some reason, his mock formality drove her into a frenzy. She dropped to her knees so fast that she was vaguely worried that she may have bruised herself. The cock springing to attention in front of her drove all other thoughts away. Big... bigger....than.... She couldn't even bring up the name of whoever it was this cock was bigger than.

Beth commenced the best blowjob she could manage. She wasn't very practiced, given her relative sexual inexperience, and Jeff was girthy. She gagged and drooled, doing her best not to hurt his beautiful cock with her teeth.
"Sorry..." she paused to spit. "I'm not the best...." she couldn't say the word "cocksucker" even though that was what she was doing.
"You're amazing, Miss Wilson." Beth didn't understand the mixture of shame and feeling pleased at his compliment. "Better than any girl I've had."
Jeff guided her actions with a hand on her head, pumping with fervor. "You're going to make me blow in no time."
Beth redoubled her efforts, gagging and drooling whenever he went too deep. Her eyes leaked tears down her cheeks, and she stroked his spit-slicked shaft with every bob of her head, until he was grunting and cursing and shooting cum into her throat. She gagged, spitting everything onto the grass.
"Sorry, Miss Wilson. I couldn't help myself." Jeff stroked her hair, and she looked up at him with regret and arousal.
"I can't believe I just did that."
"I can..." he was wiping his dick with a towel and pulling his shorts back on. "You should probably get going. Paul could come downstairs for something, and we don't want him to see this." He was picking up her shirt and bra, holding them out to her.
"Th...that's it? We aren't...." she didn't know if she was angry or relieved.
"Oh... you want more, huh? Well... Why don't you come to my baseball game on Sunday. 2:00 PM at Miner Park. After the game, we should have plenty of time to do more."
Beth's mind worked while she dressed. Brian was playing poker at Mason's house on Sunday: he did every other Sunday. He wouldn't be home until at least 8. Oh god, Brian... I'm sorry! But she wasn't sure she was sorry enough to turn down Jeff's offer.
"I'll have to see if I can make it." She said, grabbing the towel from his hand and wiping her mouth and cheeks with it. Her face would stink of cum and sweaty male musk, but at least it looked clean. She straightened, looking at Jeff shyly. "I..."
"Thanks for the beej, Miss Wilson," Jeff swallowed anything she was going to say with a toe-curling kiss. "I look forward to more." Well aren't you confident?

Beth drove home in a daze, thinking in turns about the erotic and illicit act she had performed, and the guilt and shame when she thought about Brian.
