What's that sound?

You're taken by surprise as the bathroom door swings open and you turn to see your wife standing there, completely horrified. In a panic, you rip your cock out of Gemma's ass, only to blast a geyser of searingly hot cum all over the girl's spine and into her damp hair. The heavy weight of your cock, finally spent, uncontrollably slaps down on top of her right in between her ass cheeks, leaking cum down the crack and into her gaping asshole. You cannot think of a worse possible scene for your wife to be witnessing right now - her husband just having blown a gigantic load all over his friend's daughter's ass in her own bathroom which is completely flooded with soapy water that's seeped into the bedroom carpet past the door.

Gemma doesn't acknowledge her presence, instead slumping her head over the end of the bathtub and gasping for breath, so close to her own orgasm but now deprived. Her fingers stray between her legs to her clit, but you can't be distracted by that right now. You stand up, trying to think of some plausible explanation for your shocked wife, but your still erect cock, rubbed red and raw and dripping with cum and pointing right at her, can't be helping the situation one bit. Tears begin to well up in Rebecca's eyes, and she turns and runs out of the bathroom. You stumble out of the bathtub, almost slipping over on the wet floor and cracking your head against the door, before grabbing a sopping wet towel to cover yourself and chasing after her.
