Growing increasingly desperate, Jimmy finally sat up and quickly tugged his swimming trunks downwards, wincing a bit in pain as his enormous hardon sprung free of it's confinement and made the waistband snap back right on his balls.
With his trunks pulled halfways down his ass and his erection standing out like a spear in front of him, he then grabbed the bottle of sun oil and poured a good amount of it into his hand before starting to whack off at the incredible sight in front of him.
Jenny meanwhile was still fast asleep and completely unaware of her brother's actions, a content smile on her lips as she dreamt of well hung studs doing forbidden things to her lovely young body. The only thing making her stir was the sudden lack of hands on her shapely ass...
After only a few moments of furiously jacking himself, Jimmy had to admit that his own hand couldn't give him satisfication enough. Not with such a beautiful girl right under his nose. The desire to set his meaty pole to female flesh grew stronger for every second, and while trying to find a solution to his dilemma he eventually got his hands back on his sister's buttocks again, unaware of the relieved sigh escaping her soft lips as he started kneading them harder than ever under his palms.
Feeling his sister push herself back against his rough handling of her butt cheeks, he finally couldn't take the pressure any more. Swift but careful not to wake her up he climbed on top of her, his hands never leaving her naked skin as he kneeled down over her slender thighs. Getting a good grip he then spread the firm globes of her ass as wide as he could, letting out a loud grunt as he pressed his massive shaft up through the well-oiled crack.
"Ohmygod... What am I doing...?" Jimmy mumbled to himself as he slid himself forth and back between his sleeping little sister's buttocks, feeling the material of her tiny string slide against the underside of his massive erection. He knew very well how forbidden his actions were, but couldn't for his life bring himself to stop. "Just please don't wake up right now Jenny!" |
