Jen was the most relaxed she had been in three months. Her two kids were with her mother in another state, her husband was on a work trip in another country, and she was all alone for a few precious days. Currently she was luxuriating in a steamy bubble bath and pretending she was in a high-end spa, ignoring her children’s water toys that populated the area around her as well as the fact that she was a little too tall to lie comfortably in their bathtub. As she lay her head back on the cool porcelain rim her hands absent-mindedly roamed her body under the scented froth. They lingered on her stomach for a few moments- this was an area of self-consciousness for Jen as she hadn’t had time to exercise. What working mother does? Even so, no sane person would have considered her ‘fat’ or ‘chubby’ as she was in fact a quite slender woman. It was her body though and she missed the days when she didn’t have to worry about what she ate. She sighed and her hands navigated towards her hips, significantly wider after two births. Jen knew that at least her butt hadn’t had as rough a go of it as her tummy. It was still a nice, round posterior with little sag and she was proud of it. Removing her retro librarian-style glasses and placing them on a side table Jen slid her head down to douse her springy brown hair and closed her eyes. The skin contact was feeling good and her right hand glided to her vagina, sliding over the thatch of pubes and tickling her clit. Her other hand cupped her left breast and massaged.


Jen couldn’t remember the last time she had pleasured herself. Her sex life was perfectly acceptable for her lifestyle and she seldom felt the need to masturbate. Dan was a loving and devoted husband and father and she loved the life they had made together; sex happened when there was time and Jen had no reason to think she needed anything more. Still, an opportunity like the one she had now were so rare Jen figured what the heck. The only problem was she was having trouble thinking up a fantasy. Flings from her past were hazy and unstimulating, handsome actors were flat and boring, and she had no colleagues at work that stoked any sort of fire inside of her.


As she scrolled through a mental rolodex of potentially sexual interactions she felt a tingle up her spine and a hardening of her nipples. Her eyes shot open and she gave a little gasp- she had just imagined her brother-in-law Mark. Her hands were still in their intimate positions but paused as Jen tried to shake the reverie. She couldn’t masturbate to her husband’s brother, could she? It felt wrong and gross and despicable...but her body kept reacting to the thoughts of Mark’s naked body. ‘Where is this coming from’ Jen asked herself though deep-down she already knew..


Mark was Dan’s younger brother and lived nearby. He was around a lot because he was family and he often babysat the kids when Jen and Dan needed a night out. Jen had grown close to Dan’s family and considered herself lucky to have a good relationship with all of her in-laws. Mark was funny, thoughtful and smart and Jen loved how he was with her children. She also considered Mark a handsome guy, with a tousle of dark brown hair and sensitive eyes. Mark took good care of himself working hard to stay trim and fit whereas her husband Dan was substantially over-weight. Jen never much minded Dan’s weight (except when she worried about his health) but she couldn’t deny that Mark had a great body.


Jen had spent a lot of time with Dan’s family over the years and in that time had seen Mark in various stages of undress. He had never been naked in front of her but certainly with his shirt off and Jen had caught her gaze resting a few seconds too long on his strong chest and abs. Mark sometimes wore sweatpants and Jen had also noticed a shall-we-say significant lump in his crotch. Jen knew she wasn’t crazy though because her sister had mentioned the same thing to her at a Thanksgiving one year. Her sister and she were close and spoke about anything and everything so the comment about Mark’s ‘lump’ was sort of an offhand remark but it stuck with Jen nonetheless.


Jen, with her hands still suspended in their motion, decided she would allow herself this taboo fantasy and shut her eyes. She began imagining a scenario where she and Mark were caught driving in a snowstorm together and forced to pull over to the side of the road. The two of them decide that in order to stay warm they will get naked and sleep together in the backseat. They strip and hold each other close. Jen feels a penis on her thigh that far outsizes any other penis she’s ever seen or felt. She begins rubbing her vagina against it, Mark opens his mouth to potentially protest but Jen puts a finger to his lips and grabs his large rod with her other hand. She feels it getting bigger and bigger until there’s nowhere else to put it except inside of her....


Jen let out a startled sound as body began to vibrate. Her hand that held her breast now held onto the side of the tub to steady her spasming body. She opened her eyes and caught her breath and realized that was first orgasm she has ever had in her life.

“Good morning!” Mark said, out of bed but still in loungewear.

“Morning Mark,” Jen replied.

“Where is everybody?” he asked, grabbing a mug from a cupboard and filling it from this morning’s coffee kettle.

“Dan’s out with the kids to see the new Zootopia.” Jen said as she looked up from her phone. She watched Mark fill his coffee mug, her eyes glancing down and catching on that same lump she had noticed before. It looked simply enormous to her. Was that the head she was looking at? Jesus!

“Oh that sounds like fun!” Mark said as he added milk to his drink. He grabbed a stirrer. Jen watched Mark’s lump as he stirred. Naturally it began to wobble and Jen watched entranced like a snake to it’s charmer.

“What are you up to today?” she asked.

“I’m going to the Ferguson to see their new Miro exhibit. It’s supposed to be fantastic. Do you wanna come?”

“Yeah I’d love to actually! I feel like I haven’t done anything culturally in a long time.” she said with a laugh.

“Hah yes it’s tough being a mom. Well I was going to go shower first but then we could go around 11:00?”

“Perfect!”

--------------------------------------------

As she sipped on her second cup of coffee Jen realized the first was just starting to hit. She climbed the stairs and stepped into the hallway. From her vantage point she could see into Mark’s room. Mark who had evidently finished with his shower and was about to change into fresh clothes. Mark who was stark naked and whose penis was entirely visible in all its thick heft, draped over a similarly hefty scrotum.

Jen’s breath caught in her throat. “Good god.” she said to herself.

“You like what you see?” Mark’s asked, as apparently Jen’s thought had inconveniently escaped her lips. He stood, nude from the waist down, smiling at his sister-in-law.

“I’m so sorry! I’m sorry- I just had to...had to go the the bathroom” she sputtered, horrified at having been caught.

“No, it’s OK, I was just joking. It’s OK Jen!” Mark tried to appease her. Jen calmed down.

“It’s just,” she paused as she considered what she was about to say next. “It’s just...so big. Ohmygod, what the fuck Mark?” She said, with the hint of a joke.

Mark chuckled. “Thanks.” he said, reaching for the pair of boxer briefs on his bed. Now Jen really had to consider what she was about to say.

“Can I touch it?” She words came out of her mouth like they had been trying to. Mark stopped mid-reach like someone had hit his pause button. A smile came over his face.

“Yeah, sure, if you want to. Is everyone gone?”

“Yeah it’s just us here,” Jen said as she made her way toward her new best friend. She pushed Mark into a seat on his bed and crouched between his legs. Mark looked down proudly at his appendage. It moved as he breathed like some of slumbering beast. Jen placed her right hand around it, her fingertips just barely touching.

“Okay, how do you not have a girlfriend?” Jen said with a smirk. She couldn’t imagine a girl passing up a catch like Mark ever, let alone once they realized what he was operating with. Mark chuckled.

“I dunno, I just don’t. I don’t really date that much to be honest.” Mark responded, feeling the start of blood rush to his organ from Jen’s touch. His cockhead began to fatten up and rise like a waking bear. Jen watched the hammy corona start billowing up toward her face. She felt the distance between her fingers grow. With her other hand Jen tried it’s best to cup Mark’s fat scrotum and began gently fondling it to see how big she could get this baby behemoth.

“Ooh fuck yeah.” Mark uttered, falling backward onto a pillow to enjoy his massage. Mark heard Jen gasp and sat up on his elbows.

“Everything OK?” he asked.

“It’s SO big! How do you..when did you..do you know how big this is?” Jen asked, befuddled.

Mark smiled and nodded. Jen eyed it comically. She made up her mind and began an attempt to get his head in her mouth. Mark’s eyes widened as he realized what was happening. He reach over and closed his bedroom door just in case and looked down to see Jen spit generous wad on his head and work it in with her hand. He was impressed and turned on. Jen put her mouth to the broad tip and began opening her jaw to try to accommodate Mark’s large dong. Her teeth were dragging a big on the fluffy pink skin so she tried widening more, feeling the jaw muscles that had never been used jump into action.

GWwhruoppahh. Odd noises came from her mouth as she stuffed it with his fat piece of pork. She dislodged and hauked another huge loogie on his enormous member.

“More spit!” she said before embarking again on her quest. Mark watched her lips travel over the significant crown with its bulbous room, and inch down his swollen shaft. She worked her head up and down these same four inches, trying to gain steam for the next 5. Jen’s eyes began watering.
