"Oh shit, Blake, I'm so sorry! I completely forgot." Blake frantically scrambled to tug the covers up over his naked body, but he could tell from the mortified look on Linda's face that she knew exactly what he'd been doing before she walked into the spare bedroom even without the sheets settling in an embarrassingly obvious tent over his aching cock. Her eyes kept darting to it despite her best efforts to look literally anywhere else, and Blake didn't dare shift for fear of making his arousal even more inescapably the center of attention. He groaned internally, trying hard to control the desperate churning need in his balls and arrange his features into an expression of polite exoneration for Linda's sins.
It didn't help that she walked in on him wearing nothing but a bra and panties that didn't exactly conceal her obvious assets. Not that Blake was thinking about his best friend's wife while he masturbated--honestly, he was so fucking horny after three solid weeks as Joe's houseguest that he didn't really need to do anything but close his eyes and concentrate on the feel of his cock in his hand. But seeing her like that, with the broad slope of her ample pink tits only barely held captive by her straining bra and the dark curls of her pubic hair clearly visible through her translucent underwear... it didn't exactly make it easy for him to will away his straining erection.
And she noticed him noticing. "I'm so, so sorry," she burbled, pointing over at the closet with hands that were just a little too animated. "I just, I needed to grab a blouse and a skirt, and I forgot that you were in here, and I... I don't know what I was thinking, especially not after, um. You know." She blushed, a bright red flush spreading all the way down her cheeks to her pendulous breasts. "The last time." Blake's cock twitched. He could see in his peripheral vision that a little dark spot was beginning to form where the tip rubbed against the soft cotton sheets.
Because the last time wasn't the first time. Six times now in the last three weeks, Linda had completely forgotten that Blake was crashing in their spare room while he tried to get his affairs in order after the fire that destroyed his house. Every time he began to relax and think of the bedroom as a private space where he could take a little private time, the door would burst open just as he was in the middle of jerking off and he would wind up with another case of blue balls that simply wouldn't go away. And she was always... god. God damn. Blake tried like hell not to think about how lucky his old college buddy was, but it was hard as hell when Joe's wife always wandered around like a scatterbrained ditz who didn't know where her clothes were.
It was incredibly fucking hard. And so was Blake.
"I, uh, I'm just gonna...." Linda nodded toward the closet, inching her way deeper into the room and trying to pretend she didn't notice Blake's cock bobbing and twitching under the sheets. "I, uh, just a quick, um, y'know, just gonna grab something to pull over myself and then I'll be on my way and you can, um, uh, uh... nap." She turned around, bending over and inadvertently showing off the amazing curves of an ass that her panties only notionally covered. Despite himself, Blake's fingers crept down under the covers to encircle the base of his cock. He tried to tell himself that he wasn't stroking. And as long as he wasn't stroking, he wasn't really jacking off to his best friend's wife's body.
But of course Linda tested his resolve. "Let me just see here," she muttered, her voice muffled by the interior of the closet as she dug through the boxes of clothing and inadvertently set her ass into one gyration after another. "Nope, that's not it, nope, no--I'm sorry, I really don't mean to be keeping you, um... keeping you up. I know you must be really tired, and here I am barging in on you when all you're trying to do is relax." Blake recognized the forced politeness in Linda's voice--he had unfortunately gotten very used to her valiant attempts to put him at his ease in situations like this, whether it was by coming into his room without knocking or wandering out into the kitchen without a robe or hunting for a towel in the linen closet in full view of the living room where Blake was trying desperately to ignore her sleek, wet body. God, by this point he'd probably seen as much of her as Joe had.
