And those were just the hottest of Jenny’s friends. Even Giana, the obligatory frumpy, book-wormish one, looked fuckable enough in her relatively modest yet still form fitting one piece.
Billy stroked madly at his cock as his eyes darted from girl to girl, imagining each one naked, on their knees, begging for the cum boiling within his balls, ready to unload on their eager upturned faces…
Just as he was about to explode, the bathroom door flew open. Billy turned to find his sister standing there, her face a mix of shock and anger.
“Billy? What the actual fuck???”***
Despite her ‘masturbation interruptus’ earlier, and having to spend most of the morning in the hot kitchen with Mom, Jenny had managed to relax and enjoy herself once the party had begun.
That is, until Billy had made his Grand Entrance. His obvious gawking immediately annoyed her. How dare he come out here just to oogle her friends?
Worse, he never once looked HER way. Jenny knew she couldn’t compete with some of her friends in the looks or body department. But still, she looked pretty darn sexy in this bikini, so why hadn’t he even noticed?
Jenny shook these thoughts from her head with a grimace. Why was she MAD her brother wasn’t looking? He’s not SUPPOSED to get aroused by his own sister, no matter how skimpy or revealing her outfit!
Speaking of aroused, Jenny also easily spotted the tent in his trunks. So did her friends, producing silent smirks and eyerolls knowingly exchanged between them.
When Billy had finally left the pool to head inside, Jenny decided to follow him to give her a piece of her mind. She gave him a few moments to get inside so it wouldn’t be obvious she was following him, then headed in herself.
She went upstairs to his room and was confused when he wasn’t there. The bathroom door was open as she went by so he certainly wasn’t there either.
Heading back downstairs, she realized he must have just ducked into the guest bathroom. She was about to knock when she heard the sound of what could only be heavy breathing.
Leaning her ear to the door, she jolted when it swung open just a crack. Apparently Billy, in his haste, hadn’t closed it all the way.
Peeking in, Jenny’s jaw dropped at the sight that greeted her: Her brother, bare assed and facing the window, his right arm a flurry of motion as he moaned steadily.
‘Oh my fucking God, he’s jerking off!’ Jenny thought wildly. She had a moment of frustration at not being able to actually see his dick, a moment that quickly turned to anger when she realized why he was facing the window.
Jenny threw the door open wide. “You fucking perv!”
Panicked, Billy instinctively turned towards her, which of course only made the situation worse as he was now completely exposed to her. He was also right on the edge, and the shock of being caught caused him to lose control.
Jenny’s eyes bulged as his cock twitched wildly, launching stream after endless stream of thick cum all over the bathroom floor. Jenny wasn’t completely naive, she’d watched porn before. But she’d always thought both the cock sizes and quantity of ejaculate they expelled exaggerated.
