They spot you.

You spent too long staring, and before you had a chance to find out what you wanted, Morgan ended up spotting you.

"What the hell are you doing, creep!?" There was actual anger in Morgan's voice; she was cheating on you with Bill, yet had the sheer nerve to get pissed off at you for taking a look.

Bill looked over too after hearing Morgan's outburst, but having an audience wasn't enough to stop him from hammering Morgan's wet pussy.

It sunk in then that they were both stripped naked, and Morgan's hot body being on display made your already erect member throb harder in your pants.

"Dude...go fuck Janelle, we're busy down here." Bill didn't seem particularly upset, but still tried to get you to leave.

Morgan on the other hand, seemed intent on acting just as angry as if her boyfriend's friend had abruptly decided to peep on them having sex.

"This tiny-dicked pervert is pitching a tent while he watches us go at it!" Morgan's voice was a little breathless from the pleasure she was getting from fucking Bill, but was still filled with cruel bitchiness.

"What kind of creep," Morgan paused to moan as Bill's cock rubbed inside her in just the right way, "would rather watch two other - hotter - people fucking instead of having sex with a girl on his level?"

Morgan's words stung, and she was vehement enough to make it feel like you were really getting cussed out for interrupting your friend and HIS girlfriend having sex...

You felt an urge to just call Morgan out on her bitchiness, to tell her you know she's cheating on you...
