Part 1 is here

"Oh, yesss," Adam hissed as Becky sunk her new manhood deep into Adam's wet hole.So this is what mom's pussy feels like, he thought to himself, gazing down past his huge jiggling breasts to the dark tuft of hair between his legs. Becky held his leg in the air and they both gazed down as she slowly filled him, her length traveling up through Adam's core. He could feel each inch of the warm shaft as it spread him apart. He felt his pussy lips clutch it, felt the moisture spread up and down the wonderful shaft as it slid in and out of his mom's body."Goddamn you feel so incredible," Becky moaned as she slowly fucked him.Adam agreed as he watched his tits wobble with each thrust. If this was what his mom felt like during sex he wondered why she wasn't constantly fucking his dad. Maybe it was the novelty of being a woman, combined with his own natural horniness. Whatever it was, he couldn't get enough of sex in his mom's body. He begged Becky to hold on and fuck him faster.He cooed as she thrust deeper, sheathing herself to the hilt inside his wet heat as his mom's voice spilled from his lips. Adam grabbed his new tits, suddenly desirous of this body he'd previously found disgusting. Every inch of it filled him with pleasure and he touched and stroked and squeezed himself as Becky fucked him faster.One hand crept between his legs and he stroked his mom's tight clit as Becky's balls thumped against his ass. His voice rose in pitch and then he was cumming, his entire body quivering around Becky's girth. She moaned in his ear and he felt her cock throb inside him, felt each pump of hot seed as it filled his body and doubled the pleasure.When he came down he was still dripping wet and ready for more. Now that he'd discovered his mom's sex drive, he wanted to explore it to the fullest. Even if it meant exploring with other people in the hotel.
