Phil felt his balls begin to boil and pulse, and knew that his cum was getting very close. In the back of his hearing he could sense the noise from the party downstairs, but his attention was devoted to what Janet was doing with her mouth. Pretty, sexy Janet had been flirting with him since they arrived, and he had drifted away from his wife, and returned her advances; and now she was on her knees in an upstairs bedroom of his friend's house, getting his dick sucked REALLY well by his wife's friend. His legs started to tremble and his chest tightened, and he put his hand on her head. She looked up, her mouth wrapped lovingly around his shaft.
"I'm close," he warned.
"I want it," she told him, "just tap me when you're about to cum." She put her head down and returned to bobbing on his shaft, her hand and mouth working in unison, and the delicious thrills resumed in his groin. The pressure built for another twenty seconds before he tapped her head. She pulled her mouth off and stroked him, looking up like a sexy porn star, stroking his wet shaft.
"Give it to me, Phil, cum for me, cum in my mouth," she hissed, and took the head back inside her sweet mouth as he felt the first spasm shoot his cum jet up his shaft. He groaned, felt the explosion, and his head leaned back and he groaned. He looked down at her, seeing her cheeks puff as she took his hot load in her sweet, pretty mouth, and then the door opened and all hell broke loose.
His wife Connie was standing in the doorway, bug-eyed and mouth open, as he finished emptying his balls into Janet's mouth. His eyes went from his horrified wife's face to Janet's eager swallowing, and back again. He stood there, his cock in another girl's mouth while his wife watched him cum. Halfway through she shrieked his name and Janet whirled, and the last weak spurts landed on her shoulder. Janet struggled to her feet, and Connie pushed her out of the way as she stormed in. From the corner of his eye he saw Janet turn and give a 'sorry' look as she slipped out, closing the door behind her. Distracted, he didn't see his wife's hand until it struck him.
Staggered by the slap, he stumbled backwards, his withering cock flopping comically from his open pants. He stepped back to the bed and sat, tucking himself away. "Connie, come on, you-"
"You fucking bastard!" she shrieked. "You let that slut blow you?" Her face was as red as his felt, and he rubbed his cheek where she'd struck him. "You son of a bitch!" Spit spray was flying from her mouth as she screamed at him, arms flailing. "I'm looking all over for you, and you're up here getting your dick sucked?! By that fucking ... whore?! Fucking Janet?!"
Suddenly Phil's confusion and disorientation vanished and he stood, his pants closed and equipment tucked away. "She is NOT a whore!"
"Are you kidding? She's up here sucking your dick, she my goddamn FRIEND, for chrissake!"
He bellowed back at her. "She's your friend, she's MY friend too, and you just called her a slut and a whore! Do you hear yourself?"
He saw stars again, and found himself sitting on the bed, his face throbbing where she'd slapped him a second time. He looked up and she had a shocked look on her face, as though she were more surprised than him.
"How- How could you do this to me?" she gasped.
He stood back up and reached for her, but she pulled away, turned her back. "You're angry," he started and she whirled to face him.
"Of COURSE I'm angry! Why shouldn't I be angry?" She stammered, her mouth moving, nothing coming out, then tears came to her eyes and she managed, "How could you do this to me?"
He sat back down and thought for a minute as she stood there, tears trickling down her cheeks. He gathered his thoughts and looked her in the eye.
"Is that really the question you want to ask? Is it?" A look of confusion crossed her face. "Before you answer, ask yourself: do you really want the answer to that question?"
"Yes!" she sobbed. "Yes, I want to know! How could you do this to me?" She took a deep breath, composed herself. "How could you leave your wife, your WIFE, at a party and let Janet suck your dick? Yes, I want to know."
He nodded, silently, looking at the floor. "Fine," he started. He looked back up at her. "You're angry; good. Maybe that will help. Maybe this time you won't run away." He stood, approached her, and this time she didn't run, and he took her by the arms and led her to the bed, sitting her at the edge. He began to pace, and then spoke.
"Tell me, Connie, can you remember the last time YOU sucked my dick?" He looked at her. "Because I can't. I can remember asking you to, a while back. In fact, the last time I asked, I BEGGED you to."
"I don't like that; you know that."
"I'll tell you what I know. I know that you don't like the IDEA of it. And I know that you are afraid that if you DID it, you MIGHT like it."
"Don't you make this about me," she interrupted angrily.
"Connie," he said, pausing and shaking his head. "Don't you see? This IS about you. You have this thing about liking sex, and it-"
"I like sex." she defended.
"No, Connie, you don't. You don't. Occasionally you NEED sex, when your body tells you so. And on those rare occasions, you seem to almost enjoy it. But after it's over, it's over, and it's out of your mind until the next time you need to shame yourself." He turned to face her. "You think it's dirty, and it embarrasses you, even when you enjoy it." He paused. "And that's not very often."
