His breath caught in his throat. Was that the front door latch? Still sprawled out naked on the bed he racked his brain trying to remember if Sara had said anything about coming home early today. It was difficult to hear anything over the thumping of his own heart as he strained his ears for any tell-tale sounds of someone approaching up the stairs.
Shamefully he looked down at his hand still clenched around his swollen cock and saw the soft, delicate black lace panties he had wrapped around his shaft were now stained with precum. A creaking stair and the rhythmic sound of ascending footsteps jolted him back to reality. Jumping up from the bed he untangled the panties from his now deflating cock and stuffed them hurriedly back into Sara's underwear draw, slamming it shut as he whirled around to his crumpled up clothes on the floor.
He was frantically tugging on his own underwear when the bedroom door opened and in breezed his girlfriend, who upon seeing him practically naked scowled a puzzled look before asking:
"What the hell is going on here?" Sara demanded.
Standing up straight he finished pulling on his boxers before shrugging and nervously answering.
"I just got out of the shower, I'm getting dressed..." Sara raised an eyebrow before dropping a hand down to her hip. Shit, he thought, she doesn't buy it one bit.
"Why are you showering in the middle of the day, shouldn't you be working?" she pointedly asked.
"Speaking of work, why aren't you there right now?" he shot back immediately.
"Broken water main, everyone got sent home early, and don't avoid the question - why are you showering midday, you better not have another girl here" she teased half serious.
He thought that would almost be better than the truth. If she knew what he had been doing with her intimates... It was just as likely to result in the end of the relationship.
Before he had a chance to formulate his next excuse Sara strode over to the dresser and, to his horror he saw he reach out for the very same panties that he had just had around his dick... that were now hanging precariously out of the corner of the drawer.
"Why are these out... Why are these wet?" she asked turning the panties over in her hands.
He could feel himself turning red, desperately trying to think of a believable excuse, any excuse.
"Perhaps they were never dry from the wash?" he ventured meekly.
Sara turned and glared his way."Like you'd know anything about the wash, besides still doesn't answer why they were out..."
He stared down at the floor knowing for certain what the next question would be and that he had no sufficient answer. Sure enough Sara turned before asking
"Were you going through my underwear drawer again?"
His head jerked up at the last word.
"Oh you thought I didn't know," she laughed. "Oh come on, it's pretty obvious when they're not in the same order I put them in there. What is your fascination with my panties?"
He looked up at her embarrassed before breathing out.
"Well, I sort of like using them... to you know... Get off."
He knew it was over from the way her mouth dropped open in surprise and horror.
"What, you use my panties to get off!? How long have you been doing this!?" Sara demanded.
"Since we moved in together" he replied dejectedly.
Sara had regained her composure somewhat and was now gently twisting side to side still clutching the soiled panties.
"What is it about them that gets you off exactly?"
He looked across at her tight little figure, the soft rise of her dress against her breasts and her perky ass. Well at least she hasn't stormed out or hit me yet. Might as well be honest he thought.
"Well it's the thing that is closest to pussy so it feels good to have it close to my..." he trailed off not wanting to say out loud how he defiled her delicates. "Plus it's kind of hot knowing on any given day you're wearing a pair of panties that I've cum in."
Sara bit her bottom lip softly before adding
"Hmmm, that is sort of hot".
"Well now that I know how you feeling about my panties why don't we have some fun with this." she said turning back toward the dresser.
It was his turn to raise an eyebrow in surprise.
"So you're not mad?" he asked.
"Oh no, I'm mad" she shot back glancing over her shoulder "mad you didn't tell me sooner and ask me first."
Sara turned back and was clutching two handfuls of her underwear.
"Take those off" she commanded nodding towards his boxers.
He did as he told and felt a stir in his loins at having been told what to do. It was something new for Sara. New and exciting it seemed.
Standing naked he watched her spread the panties out on the bed before him.
