No mess!

Beth had to cover her mouth with one hand to hold in her squeals and moans while Kyle pounded her pussy savagely. Her fishnet-clad legs rested on his shoulders as his flesh slapped against hers vigorously. Her thoughts were fuzzy, but she couldn't help but compare the cock reaming her out to the one she had been accustomed to, and to find Brian's member wanting. Not to mention his technique... and ferocity... and stamina... Kyle was his brother's sexual superior in virtually every category.
"Why are you so hot? It's not fair..." Kyle whispered.
"Same to you, baby..." she moaned. Fair didn't matter. Only the dick rearranging her guts mattered in that moment.
Eventually, even Kyle's stamina started to run dry, and she began to recognize the look in his face.
"I'm..."
"Uh, huh? Cum for me baby.... let me drain you dry." She pushed him back, climbing on top to work his iron-hard shaft and suck his cock head, still wet with her sweet stickiness. Kyle grunted, shooting a pent up load into her waiting mouth, which she showed off lewdly before swallowing.

Beth laid on Kyle's chest for a while as they both soaked the afterglow of illicit sex. There was an uncomfortable tension, but the euphoria was stronger.
"So..." Kyle cleared his throat.
"Yeah." she sighed.
"That was..."
"Yeah..."
"What do we...what are we going to do about... this?" Kyle mused.
"Why don't we worry about that later..." Beth kissed his chest, and then his lips, and he seemed content to agree.
"Okay then..."
Beth returned to her bedroom by way of the bathroom, washing up and stripping off her fishnets before climbing, nude, into bed. Sleep hit her faster than she was expecting, and took her away into dreams she did not remember.
