Don't Tell My Sister! I Cheated With My Wife's Sister and Fucked Her Tight Little Asshole
When my wife was away on a business trip, her younger sister showed up at my door wearing the shortest shorts and a crop top that barely contained her perky breasts. The look in her eyes told me everything — this night was going to end with me balls-deep inside my sister-in-law's virgin-tight asshole.
What started as «just talking» quickly turned into heavy breathing and wandering hands. She purposely ground her round ass against my crotch until I couldn't hold back anymore. I pinned her down on the sofa, ripped her shorts off, and stared at that perfect, pink, untouched little hole.
«Brother-in-law… please don’t tell my sister…»
Her sweet, trembling voice only made me harder. I spat generously on her tiny anus and slowly worked a finger inside. She moaned like a whore while pushing back, begging for more. When I finally pressed my thick cock against her impossibly tight entrance and pushed in, her eyes rolled back and she screamed in a mixture of pain and overwhelming pleasure.
Brutal Anal Training
Her asshole gripped me like a vice — so tight it felt like it was trying to milk me dry. I fucked her harder and deeper, moving from the couch to the bedroom window, pounding her perfect ass while she cried out, «It’s too big… you’re going to break me!»
By the end I had her face down on the bed, ass up, slamming into her ruined hole until I exploded, flooding her bowels with thick, hot cum. She came so hard her whole body shook, her stretched asshole pulsing around my cock as it overflowed with semen.
Afterwards she lay there panting, cum dripping from her gaping asshole, and whispered with a naughty smile: «Next time… I want it even rougher.»
This is the ultimate forbidden cheating fantasy — completely dominating my wife’s little sister and destroying her tightest hole.
