I was in the bedroom, home early, and hadn't bothered to take my coat off yet when I heard my wife come through the door. Before I could say anything, I heard her as if talking to someone. And she was: a male voice responded. I couldn't really hear the words, but the tone was apparent as she laughed wickedly and there was a silence and then very quiet talk. I didn't know what to do, and half out of panic, half out of curiosity, hid in the walk-in - which gave a direct view from the foot of the bed.
And shortly they both came up, she with a tall, very muscular, just slightly overweight black man. Immediately they tumbled into bed, having apparently geared up moments before. Clothes were off quickly as I was in a dumb daze. I watched as his hand went down to her pussy, she laying there with an open shirt on, bra still on, and he began to finger-fuck her.
"Damn, you're wet," he said.
She just grunted and moaned. I thought he was being rough. I could see the side of her face as she was laying perpendicular to the usual sleeping position. At times her face twitched but mostly she seemed lost in lust.
He then abruptly moved up and shoved the head of his cock right into her! She cried out, seemingly a mix of pain and pleasure. He was so fucking thick. He went in slowly, guiding himself in with his own hand, as if pushing his cock forward into her, she moaning in short bursts as his thick cock drove her apart more than she'd ever been. I couldn't believe this. I was aroused, but wasn't hard, I was too nervous.
Then she said it. Well, he said something first, he asked her if she was okay. But it was her reply that was so very memorable and that changed everything, that dwarfed even what I had just seen. She cooed, "I'm in heaven!"
Holy shit! My wife never said that phrase to me and never sounded quite like that. I was frozen. I was half-aroused but now also, experiencing this for real, half-terrified for undefined reasons, I suppose rooted in inadequacy feelings as waves of chills went through me and my stomach had butterflies.
Soon he was half in and then they moved into the "normal" position on the bed, into a missionary position as well, as her bra and shirt came off. So all I could see was from behind, basically, seeing his cock pumping her pussy now. I started to be happy for her. She moaned as he began to fuck her in earnest. Most of his cock was in her as he began pummeling her, his huge rod spreading her apart and he hitting the depth of her pussy as it was clear she couldn't take more. Not yet, that is - she was clearly stretching more and more as his pumping became more pronounced and more met by her eager thrusts back. His cock was deeper in. His balls now obscured my view too much to figure out how deep, but nearly all the way in. I could swear he was 10".
