He could imagine her becoming a stripper. In fact, since she was on the verge of flunking out of college, that might be her best option. She loved to dance, she loved the boys, and she was a natural flirt. And God knew she had the body for it.
"Come on, Mercy," he said, wrapping an arm around her shoulders. He was six four, so at five feet even she seemed tiny. The heels helped a bit. Randy turned her toward her bedroom, and got her walking. "Time to go to bed."
"Is it your birthday?" she said.
"No. That was last month."
Mercy frowned, looking confused.
"Did I sleep with you for your eighteenth?"
His heart started racing, and something stirred in his genitals. It got real hard to breathe.
"Of course not," he said.
"Oh. Damn, I was gonna." Mercy giggled. "Hey, when did my tits come out?"
Mercy stopped, and started fumbling with her clothes. Randy watched, transfixed, as she got absolutely no where. All she managed to do was squeeze and push her tits around, and her top might've even slid down her body some more. She was putting on quite a titty show for him.
"I guess you're a happy boy," Mercy said, giving him a mischievous look. "You finally get to ogle my titties. Now you can go whack off."
That kind of pissed him off. "Maybe I'll whack off on your titties after you pass out."
"Oh," she said, breathlessly and looking highly aroused. Her nipples got hard and erect quickly, and she unconsciously ran the tips of her fingers around and around them. "I'll lock my door, and you'll miss out on enjoying my body again. Ha."
"I'm so over you, Mercy. And, besides, I can't miss something I never had," Randy said.
"Oh, I never thought about that," she said.
"Yeah? Think about this," he said. Randy wrapped her up in his arms, squeezing tightly. Her head rolled back, and Mercy moaned. He pulled her into a deep, passionate kiss, and she groaned low and wantonly. After several minutes of deep French kissing, Randy released Mercy, who fell straight down to her knees. "I bet you won't forget that for a long time."
Mercy didn't answer. She looked utterly dazed. Randy never saw her more beautiful, more desirable, and more available. He pushed his pajama bottoms down until his erection popped out. Then he buried one hand deep in her hair, at the back of her head.
"Eat me, Mercy," he said.
With that Randy guided his cock straight to her slightly parted, glossy lips. At the same time, he pulled her face in with his other hand. Mercy's mouth opened obediently when the dick head pressed to her lips, and she slowly swallowed him until her lips were wrapped tightly around the base.
Holding her head still with both hands, Randy started pumping in and out. At first he went slow, not sure her booze-addled brain could handle anything too fast. As she proved up to the task, he increased the speed. Soon Randy was banging the hell out of her mouth. She clutched at his butt, sinking her long red nails into that tender flesh and stoking his ardor.
When he accidently pulled too far back, and came out of her mouth, Mercy grabbed it with her left hand and gave it a couple of pumps. Then she licked his shaft all the way to his balls, and back up. Mercy rolled her hot, wet tongue all around his dick, driving him wild. She had everything tingling, his insides quivering, and balls aching to release in nothing flat.
Then she opened wide, and swallowed him all the way down again.
"That's how you do it, Mercy. Suck it like a big girl," he said, really more of a moan.
Mercy bobbed up and down his cock, and then gave him the most intense head of his life. It felt like his entire body became electrified. Randy felt his body cross over, and begin that mad rush to climax. Once he crossed that line, she could stop but his body would not. He would climax, and he grinned. And then the pleasure of that first incredible gush washed through him.
"Yes! Swallow it all, Mercy."
Randy watched her throat working. She swallowed that first shot of cum without hesitation, and the second was fast on its heels. Unfortunately, that was all for his drunk step-sister. Mercy's eyes rolled up, and she fell straight back to the floor. His jaw dropped, and that second load came squirting out. Randy watched it spurt, flying in an arch, and splash land right between her tits. And he came two more times, each a little less than the last one. Each spurt hitting her naked tits.
"Damn, I was just joking about coming on your tits while you slept passed out," he said, grinning. "But my cum looks good on you."
With wet, sticky dick in hand, Randy headed for the bathroom to clean up. And he really had to piss, too. When he returned ten minutes later, Mercy was still sound asleep in the front entry, legs still curled up under her. His cum was becoming more liquidy, and starting to dribble down and around her tits.
