Matthew tidied up the apartment while Bethany was out for dinner with Rick. In keeping with her rules for tidiness, this was a matter of re-aligning anything out of place and wiping down surfaces. He also prepared and ate a light dinner for himself and made certain the kitchen was spotless well before the arrival of Bethany's text announcing her imminent return lit up his phone.
With a level of anticipation that had been building since Bethany went out, Matthew was ready. He had moved into Bethany's spare bedroom when his younger sister suggested its availability after he was laid off from his work as a result of the pandemic. When he moved in, Matthew knew he was being granted a huge favor by his sister's friend. He applied himself to meet Bethany's expectations for a roommate, a small burden in addition to the small share of the rent she asked of him.
It was only after he agreed to Bethany's simple rules to keep the apartment tidy that he had learned that she was an on-line erotic performer with an exclusive list of clients. One, at least, apparently paid well to watch her perform for her cameras with Rick or other stunt cocks, as she called them, in her stable of contacts.
As he waited for Bethany's return, he contemplated those times he had fallen short of those expectations. The rent she asked of him was a bargain, and he readily agreed to anything she demanded in order to avoid being sent away. Those instances had led to him finding himself naked and across his beautiful roommate's lap for punishment and maintenance spankings followed by corner time until she released him. In redoubling his efforts to please Bethany, Matthew accepted new rules, including a requirement to be nude in the apartment at all times. He was, however, still expected to be out of sight whenever Bethany had a guest.
A few nights after he had first moved in, Matthew had lain in bed and listened to Bethany and Rick have loud and vocal sex. That night his perception of Bethany changed irrevocably from the skinny friend of his little sister that he had remembered, to a well-developed and self-aware young woman who confidently used her sexuality for her employment and to shape the relationships around her. And that now included her relationship with Matthew.
Matthew hovered at his bedroom door, only closing it tightly when he heard Bethany and Rick come into the apartment. The first time Matthew had listened to Bethany and Rick, he spent the hours of their session with his own hard cock in hand, steadily stroking it through three orgasms. The combination of that memory and the sexual tension that Bethany had consistently maintained in the apartment ensured he was always in the same position when Bethany entertained. Already naked, Matthew's cock was hard and dripping by the time he stretched out on his bed and listened for Bethany and Rick to enter her bedroom.
With copious precum to lubricate his cock, Matthew reached for a set of photos that Bethany had given him to help with his visualization at times like these. Professionally shot boudoir portraits, a few downright pornographic, there was one that he always seemed to be holding when he came. In that image, Bethany wore a blue leather skirt and white lace bra. Sitting on a straight-backed wooden chair, the same one she used to spank Matthew, Bethany was holding her paddle in her hands. Matthew didn't know why that image held such power over him, but it did.
In the silence of his own room, the voices came through the wall with clarity. Matthew's imagination filled in around the words, "Suck my cock, Bethany," "Fuck me Rick, fuck me harder," "Cum for me, Bethany, cum on my hard cock," and "Oh, Rick, fuck my ass and fill me with your cum."
Matthew came as he heard Rick groan and Bethany shout that she was cumming again. With his whole body shaking as he imagined a thick cock deep in Bethany's lovely round ass, Matthew's first spurt of cum reached his chest, and the subsequent spurts of diminishing power landed on his stomach. The completeness of his orgasm left Matthew feeling a little light-headed and in that mental space where the flow of times seems unsteady. He lay there, still holding his cock, as he focused on slowing his breathing and getting ready to listen to Rick and Bethany's encore performance.
Matthew realized he wasn't alone at the same time as he recognized the sounds he heard were the apartment door opening and closing. The hinges one his bedroom door were silent to the point of letting Bethany walk in without breaking Matthew's focus on the sounds he was waiting for.
"Is that for me?" Bethany asked as she approached the bed, then adding, "don't get up Matty."
Silent, wide-eyed, and still covered with his own warm cum, Matthew twisted his head around to watch as Bethany came into his view. Bethany was wearing yoga pants in a brilliant blue material and a white cropped t-shirt. Her tousled hair and noticeably disarrayed makeup indicated she had taken no extra time to ready herself before seeing Rick out the door and walking in on Matthew.
Matthew stared wildly, looking at Bethany, at the photo he held in one hand and his own cock in the other, and down the trail of cum pooling on his chest and stomach. Bethany held a finger to her lips to shush Matthew's strained attempts to say something coherent. Then she grabbed the desk chair, spun it around, and pulled it close to bed before sitting down beside Matthew.
"I said, is that for me?" Bethany repeated as one manicured nail pointed at Matthew's stiff cock.
Matthew unwrapped his hand from his shaft and left the hand fall to the mattress beside his hip. His cock remained erect, taunting him for trying to shift attention from its very noticeable presence. Bethany smiled at his confusion and discomfort, pointing at and reaching for the photo Matthew held. Matthew obediently handed it over.
Bethany's smile broadened when she saw the image Matthew had chosen to be viewing when he came. She already knew the effect she had on his mind and body when she wore that blue skirt and white bra. And that was before he submitted to the spankings he had agreed to. Setting aside the photo, Bethany returned her attention to Matthew and spoke as she slid one finger through the cum on Matthew's stomach and chest.
"Did our short session tonight leave your satisfaction incomplete, Matty? Did you only get to have one orgasm? This does seem like a lot of cum for one orgasm."
In a conspiratorial whisper, Bethany added, "Did Matty cum when he heard Rick filling my ass with hot cum?"
Matthew's lips opened and closed but no sounds came out. His entire being was centered on the single touch of Bethany's finger as it smeared a line of cum from the center of his chest to his nipple. Bethany's fingertip slowly circled the nipple until it was coated with cum and hard enough to prove to Matthew that his nipples could be a primary erogenous zone if Bethany played with them.
"I'm still full of his cum, you know," Bethany said quietly, her finger still circling.
Matthew groaned softly. Bethany leaned forward, her cascading hair hiding from Matthew the contact of her lips and his nipple. Matthew moaned softly, then more deeply, as he felt Bethany tasting and sucking his nipple. He gasped at the sudden pinch of her teeth before she raised her head and smiled sweetly at him once again.
"Did you like that, Matty?"
Matthew was confused by the question. He liked, loved, the feel of Bethany's lips on his skin. He was less certain about the biting. There was only one answer.
