I just can't

This is all happening too quickly. You stumble back, knocking into Hallie who lets out a little yelp as she loses her grip on your belt. Your heart hammers in your chest, blood rushing to your face. You turn, knocking into the doorframe before catching yourself. As you step out of the office, the door clicking shut behind you, you hear a soft moan from inside. Jenny's voice, sultry and teasing, carries through the wood.

"Oh Meg... you're so soft..."

A giggle—Hallie's, you recognize. Then another moan from your wife.

"Oh Jenny, you're... you're good at this..."

You pause in the hallway, torn between leaving entirely and turning back. Your cock is straining against your pants now, aching with arousal. You can picture it—Jenny's perfect young body pressed against your wife, her small hands roaming across Meg's curves. The thought of your wife being touched by a teenager should be disturbing... I wander blindly a bit before coming to a decision.
