They'd tried everything during the following few days and nights, whenever they'd gotten a chance, eagerly imitating the various sexual acts they'd seen performed at the swapping parties.
The first time Rod had fucked her they'd both gone almost out of their minds, the pleasure being so sensationally thrilling. They'd both enjoyed it immensely the first time he went down on her, too. He'd discovered her clitoris while finger-fucking her and when he'd lapped and sucked that stiff and slippery passion-button she'd climaxed like crazy. She'd even learned to enjoy being corn-holed. He liked that form of fucking, but the terrific heat and tightness usually caused him to shoot off faster than he wanted to. He liked the blissful minutes leading up to the few moments of ecstatic spurting just about as much as he did the actual ejaculation.
Rod felt the tingling in his balls that meant that the jism would soon be racing through his throbbing cock and flooding Betty's mouth and throat. He glanced down and saw that she'd slipped one hand up under her dress and was frigging herself. He would've gladly performed that pleasant task – or fucked her or sucked her for that matter – but he knew that she would've told him if she'd wanted help.
He could see that Mr. Anderson was pounding faster, obviously caught up in his drive toward a spurting finish. It seemed to Rod that his wildly wriggling mother had already climaxed at least twice, but he knew that she was going for another orgasm. She had her legs wrapped around Mr. Anderson's waist and as she hunched along with each powerful thrust she clawed his back and shoulders with her hands. His finger were gripping her racing hips and their mouths were glued together in what had to be a torrid French kiss.
