The existence of a laundry room was a bit odd for a nice residential building in a nice neighborhood. The apartments were updated, the building lobby was well-designed and furnished, and the building pool and gym were well-maintained. However, the apartments did not come with hookups for washers and dryers, which meant that most residents opted to use the laundry room on the first floor.
It was a bit inconvenient for Mandy to lug her clothes from her parents' 16th floor apartment to the laundry room, especially since her dedication to intense jogging necessitated frequent washes. But, there were upsides. She had been back from college for the summer, and with all of her friends out of town going to the laundry room was actually an excuse to get outside. More importantly, the laundry room was kind of a central hub in the building that everyone went to, and this meant that Mandy ran into others who lived in the building. More specifically, Alice from the 18th floor.
Mandy was now a 20 years old and had lived in the building for 7 years. She had known 40-something year old Alice for a while by simply living in the same building, but the two struck up a casual friendship only now that Mandy was becoming a mature woman. Unplanned rendezvous with Alice in the laundry room had been a launchpad for pleasant conversations. Despite the age gaps, the two women shared a similar sense of humor and a similar situation of temporary loneliness. Mandy, as mentioned, was home for the summer while her close friends were spending it elsewhere, and Alice's college-age son was interning in his college town and so did not come back for the summer.
Another commonality between the two women was their bright smiles. Mandy's was wide and thin, stretching her prominent jaw and turned-up nose. Her brown eyes sat symmetrically atop her nose and underneath her mid-size forehead and short brunette hair. She had an athlete's body, thin and toned, and with all of her jogging and workouts, she sported "six-pack" abs under her tops.
Alice's smile was full of teeth and lit her face aglow, making her big blue eyes radiate as they contrasted with her dark shoulder-length hair. Her nose was button-like, stationed neatly in the middle of her face. Her nostrils stretched outward ever so slightly when she smiled. Overall, she gave off the impression of bubbling curiosity when she interacted with others.
The magnetic pull of Alice's smile was probably for the best, as it sat atop of a body that could very easily attract men's gazes to awkward places. Unlike Mandy's athletic body and small chest, Alice had clearly been blessed in this area. She wore casual tank tops wrapped by flannel or buttoned shirts, that were always half-opened. Her prodigious breasts never failed to make themselves noticed by separating the shirt sides, creating a crooked line from the bottom buttons to the top ones. Her breasts also betrayed their size in the way their undersides curved into her flat abs, creating a semi-circle clad in fabric. It was perhaps doubly attractive to some that she was an unassuming and innocent-looking person, acting as if her endowments were not so impressive and so decidedly lovely.
So the two women struck up a friendship. Although it relied on spontaneous encounters, those happened with some regularity thanks to the laundry room. They found out they liked similar things and were interested in similar things.
They also laughed about similar things -- for example, Casper. He was the 18-year old son of the people living in the 1st floor apartment closest to the laundry room -- in fact, their apartment adjoined it. A scraggly guy, he was usually easy to talk with. At least that's what Mandy used to think until she ran into him while chatting with Alice. Then the situation became awkward in the extreme. Around her, his judgment and decisions were gone, overtaken by an inexorable onslaught of male hormones. It was painfully obvious he was a breast man, and perhaps a MILF man, and Alice had both qualities in abundance. With Mandy by herself, Casper was a normal guy able to engage in routine small talk. With Alice there, Casper was as socially inept as can be, providing terse responses, mightily trying but failing to avert his gaze from Alice's prominent chest, and always acting quickly to finish his laundry and get away.
It was all very funny and also very pitiful to the two women, and they think much of it other than another thing to laugh about and bond over until one fateful afternoon.
Mandy and Alice were in the laundry room, purportedly to their laundries but really to catch up and chat. Casper entered and as usual, upon seeing Alice, gave off an overly quick "hello" to both women and took his clothes from one of the dryers a little too rapidly. He left as awkwardly as he entered, saying "see you later" without looking in the direction of both women.
"Well, I guess someone's clearly not over his crush," Mandy said and immediately received a soft jab from Alice's elbow. It wrinkled the black-and-pink compression top Mandy was wearing. "Don't be so cruel!" Alice chided. Along with comfy blue jeans, she was wearing a white tank top encased in flannel shirt with blue-and-white squares, with the bottom buttons closed and the top buttons opened. Both women didn't much of it until they heard a soft thud coming from the direction of one of the walls. This was the one wall that did not have washers and dryers against it, and as the sound repeated Mandy approached it and put her right ear close.
"mmm, yes..." Mandy heard a male voice and quickly withdrew her ear, surprised.
She gazed back at Alice, who herself had a questioning look. Mandy motioned for Alice to join her, and the older woman gingerly stepped over and lent her ear to the wall.
"mmm, you're so hot..."
The two women look at each other and with smiles forming on their faces. As humor was their most common go-to in their conversations, they both thought about laughing as a way to respond to the oddness of the situation. They almost did laugh, but the next sound stopped them in their tracks.
"mmm, Alice, you're so hot, you're so sexy..."
The soft thuds were coming more quickly now, and as the situation progressed it became clear to both women that what they were hearing was a man on the other side of the wall masturbating. Although the voice was heard faintly through the wall, both women realized who it was. Given that Casper's parents' apartment was the only adjoining the laundry room, and given the ludicrous heights of his infatuation with Alice, the realization that the voice belonged to Casper was inescapable.
Although shocking at first, the incident ended a bit anti-climactically. The voice quieted down save for a few grunts in rhythm with the increased pace of the thuds. Whether it was Casper's bed or something else bumping against the wall, it suddenly stopped, and the women heard a faint exhale from the other side.
"He came...." Mandy whispered and had to block her mouth with her hand to avoid laughing. But it was a strained, artificial laugh. And Alice didn't quite join it.
After a pause, as if to make sure no other sounds were coming, Mandy and Alice went back to tend to their laundry and continued to chat as if nothing had happened.
But afterwards, after the women went up to their respective apartments, after evening came and the women repaired to shower in their respective bathrooms, they each set aside time to play with themselves, culminating in quick and unexpectedly hot orgasms.
*********
Mandy hadn't seen Alice for a couple of weeks after that day. The unexpectedly hot eavesdrop remained on her mind, though, and made routine trips to the building laundry room far more exciting than usual. But as the days went on and nothing interesting happened, Mandy tried to focus on her own routine. She kept up on her intense workouts composed of long distance jogging, core training, and yoga, while working a part-time summer job to make some money before going back to college. As she went about her usual activities, she kept an eye out for sightings of her neighbors.
