Beth knelt before her brother-in-law and stared at his shorts bulging out from the pressure of his mighty cock. She reached out a trembling hand and grasped his zipper pulling it down slowly. Then she brought her other hand up and unbuttoned his shorts. His pubic hairs were visible through the open area on his shorts and she realized he wasn't wearing underwear. Beth reached up and grabbing the waist band of his shorts she slowly began pulling them down, holding her breath in anticipation as his cock slowly revealed itself to her for the second time in a week. She exhaled when the fat head of his cock popped out of his shorts, still in awe over his size. It dangled down about eight inches and she could see the large vein on his cock pulsing with power. With each pulse, it grew a little longer, a little thicker, until it was at full erection pointing directly at her mouth. Her hand reached out and hefted it feeling its weight again. Beth leaned forward and poised her mouth about an inch away from the throbbing head. She looked at the pre-cum oozing from his pee slit, thinking it was as much as David came in a regular orgasm. It must take an awful lot of lubrication to cover this monster completely she reasoned while watching a drip travel down the head to dangle underneath.

She looked up his incredible body and locked eyes with him. Never breaking eye contact she leaned forward and planted a lingering kiss on the head of his cock. Steve acknowledged her gesture of submission and nodded down at her as Beth kissed his cock again. He nodded again in the direction of the kitchen.

Never taking her lips of his cock, Beth turned her head to look in the direction he was nodding and saw their reflection in the full mirror on the back of the door. She saw her lips attached to the end of his penis and thought how beautiful and natural it made her look to be worshipping such a large cock. She watched her tongue come out and lick the pre-cum off the tip and she saw herself lick around his fat head. She opened her mouth wide and took his cock into her mouth watching its head push out her cheeks in the mirror.

"God Beth, I've wanted this since the day I first saw you in your wedding dress."

The mention of her wedding dress brought her back to reality and reminded her that what she was doing was wrong. She was a strong-willed, intelligent woman, not some mindless bimbo at the mercy of a man's desires. She made a half hearted attempt to get him off, taking his cock head into her mouth and bobbing her head up and down rapidly as she stroked his shaft with her hands, desperately trying to make this disgusting act over as soon as possible. She grunted as Steve grabbed the hair on the top of her head and forcing her head back so that she found herself looking up at his angry face.

"You really suck at this you worthless bitch, You're gonna do a good job or I'll make you do it again till you get it right."

Beth trembled with fear as she looked up at him, her head at an awkward angle to avoid any pain from him pulling on her hair. He released her and she vigorously attacked his cock trying to please him. She began licking it all over and even ran her tongue down its underside and licked his hairy balls. She ran her mouth back up and engulfed his cock swallowing four inches before gagging.

"Damn bitch, you ain't good for nothing."

She tried harder and was able to deep throat another inch. She bobbed her head on his cock rapidly while looking up at him to see if he was pleased with her.

"I guess your just too stupid to do this right so, I'm going to have to show you how its done."

Beth was so ashamed of herself she started to cry around his cock. She was stupid and worthless. She didn't know anything about pleasing a man. When Steve started to teach her she listened attentively following his instructions closer then she had any of her women's studies professors at college.

He told her to breath through her nose and relax her throat muscles. Steve had her arch her head, lining up her throat with her lips and he pushed his cock in as far as her tonsils and he began fucking her face. Thankfully he seemed satisfied with only eight inches buried in her mouth.

"Yeah baby, now your doing me right."

If his cock hadn't been so deep in her throat she would have beamed in delight at the compliment. Knowing he was pleased with her caused her to redouble her efforts. She was proud of herself for being such a good learner. Beth could only handle about seven penetrations before she had to catch her breath and to keep him happy she licked and slurped around his cock head until she was ready to deep throat him again. This developed into a pattern and time lost all meaning to her as she alternated between taking his cock down her throat and licking along the end.

"Tighten up your lips baby," he said, getting into it. He was making little thrusts with his crotch every time her mouth came down close to the base. This was turning into the best blow job of his life and it really hadn't been that bad to began with, he just needed to keep reminding her who was in control here. This wasn't just a stupid bet, Steve wouldn't be satisfied until she had willingly submitted to him both her body and her mind.

Beth felt his cock swell up in her mouth and the head seemed to grow impossibly large. On her next breather she licked around the charged head and teased his pee slit with her tongue. "Are you getting close," she gasped.

"Not yet, baby, keep going," Steve lied. He was real close. He had no intention of warning her as he wanted his new slut to swallow his cum while it was still hot.

Beth felt his cock grow even bigger and it started to tremble in her mouth. She came up for air again. "Tap me on the shoulder when your ready," she said and buried his cock in her mouth again. His cock began shaking in her mouth like a volcano getting ready to blow and she instinctively knew he was ready.

Beth began to retreat and was almost in the clear, with just the head in her mouth when she felt it jump and his hot semen sprayed the back of her throat and quickly filled her mouth. She gulped for air and swallowed most of it, feeling his hot juice slide down her throat. The second stream hit her in the face. "You bastard," she screamed at him.

His cock had jumped up against his hard stomach, when she released it and a third blast erupted from the end splattering on Steve's muscular stomach. It really did resemble a volcano she thought quickly. It fell back down aimed at her face, ready to cum again.

She could taste his cum on her tongue and the pungent aroma of so much semen filled Beth's nose, intoxicating her with its scent. All rational thought left her brain and she once again became the cum crazy slut she had been in the bathroom after she had given him the hand job.

Beth saw the eye open as she was racing to take his cock back into her mouth, and fearing she might miss tasting more of his semen, she stuck her tongue out catching it as it flew out again. She engulfed his cock again catching the rest of his load in her mouth. There was another burst that filled her mouth and caused his semen to spill out onto her chin. Then the pressure was gone and there was just a constant stream of sperm filling her mouth and she gulped it down as fast as he came.

When he was done cumming, he collapsed back onto the couch weak in the legs and his cock popped out of her mouth as he fell. She scrambled forward and kneeling between his legs, she began cleaning his dick off with her tongue. When she finished,she saw the pool of his semen liquefying on his belly and she moved up to lick it off the hard muscles on his stomach. She pursed her lips over his navel and sucked most of his semen out, licking the rest out with her tongue. Satisfied she had cleaned him up, she turned her attention to her sperm covered face when Steve stopped her.

"Leave it on," he commanded.

Beth laid at his feet and rested her head on his knees as they caught their breath. The clock indicated she had spent about forty minutes sucking on his dick and they had been the most exciting minutes of her life.

Steve had stopped panting and looking down at her he asked, "Want to play another game?"

She looked at him with a confused look on her face and replied, "Why not, I'm not the least bit tired."

That's because of all the caffeine pills I put into your drinks tonight, he thought. She was bending over to get dressed when he stopped her. "Leave 'em," he said as he grabbed her hand and dragged her back to the pool table.

She entered the garage and realizing the garage door was still open she ran naked to the door and pulled it down, shivering with excitement at the thought that if any of her neighbors were looking out their windows they would see her nude body outlined against the light.

She enjoyed playing the next couple of games with Steve, winning a few and losing a few. Steve had tried to get her to bet again, wanting to fuck her this time and though her body screamed yes, her mind made her inform him that David would be the only man to ever penetrate her pussy. Beth had never felt as liberated as she did at that moment playing pool naked with her brother-in-law. She loved the freedom that came from not wearing clothes.

"Maybe we should play strip pool in reverse and put our clothes back on when we lose," he jokingly said.
