'Hey babe, how's your girls night going?' Mike's cheerful voice contrasts sharply with Jake's heavy breathing in your ear.

Jake smirks, landing a hard slap on your ass that makes you yelp involuntarily.

'What was that sound, babe?' Mike asks, suspicion creeping into his voice. Jake mouths 'answer him' while slowing his thrusts to deep, deliberate strokes that make your toes curl
