This next part features a lot of dialog. Obviously, it’s all heavily paraphrased.

One night I was invited over to the house not for chores, but just to hang out. The house’s basement was large enough for a beer pong table and a couple of couches, so 5 of the sisters and I formed into pairs and began playing some casual, non-alcoholic games. My partner was a pledge named Claire, who wasn’t a housie. She had freckles and curly ginger hair cut to shoulder length.

Claire was a freshman and was pretty bad at beer pong, so we kept losing hard. I think this was the reason why the other sisters decided to make the game more interesting. They declared that it was time to raise the stakes, and the next game would be strip beer pong. Claire’s face turned redder than her hair, but she wasn’t going to defy the other sisters. I knew right away that our chances were slim.

The way it worked is we would have to remove a certain amount of clothing with each “re-rack.” A re-rack involves rearranging the remaining cups into a new triangle, and occurs at 6 cups left and again at 3 cups left. After the first re-rack, we’d strip down to our underwear. After the second, the tops would come off. The losers have to get naked.

Things started off poorly. My opponents were the roommates Lisa and Jessica, two seniors who had a ton of pong experience. On their very first toss they bounced the ball off the table and into our cup, eliminating two cups at once. As the game got underway, I was able to score the occasional shot, but Claire was barely hitting the table.

Ashley and Emily, who were spectating from the sidelines, started sending out taunts.

“Claire, are you nervous about seeing your first naked man?” said Ashley.

“No, I think she’s nervous about her first time being seen naked by one,” quipped Emily.

As she spoke, Lisa sank another shot, and it was time for their first re-rack. Claire and I dutifully rearranged their remaining 6 cups into a new triangle, then started getting undressed. I stripped down to my cotton boxers and undershirt. Claire hesitantly pulled up her shirt, revealing a cute pink bra, and pulled down her jeans, uncovering a matching set of pink panties. The rest of her was blushing just as hard as her face. I tried to avoid staring, but she was stunning. We piled our clothes onto a nearby couch.

We took our next shots. My ball bounced off a rim, and Claire’s ball didn’t even hit the cups. Before we knew it, Lisa and Jessica had earned their second re-rack.

I pulled off my undershirt. I finally became aware of how cold it was in that basement. Claire fumbled with the clasp on her bra, as if trying to delay the inevitable. She finally got it unhooked and tossed her bra onto a nearby couch. Her A-cup breasts were perky and cone-shaped. The pink nipples that tipped each breast were stiff in the cold basement air. As I looked, she suppressed the urge to cover herself.

I turned back towards the table and noticed the other 4 sisters staring at me with big grins on their faces. I was reasonably athletic and had a trim figure, and the sisters made no attempt to hide their leering as they eyed me up and down. I glanced back at Claire and caught her staring at me as well.

We only needed to score one more cup before our first re-rack, but our performance was deteriorating. Shot after shot bounced off the rims or missed entirely. Our opponents also struggled to hit their remaining targets, but after a few more minutes they were down to their last cup. Our spectators began cheering and howling with every shot.

Finally, it happened. Jessica sank her final shot, and the game was over. The 4 sisters cheered and applauded. Claire and I couldn’t resist smiling sheepishly. Claire turned away from me, hooked her thumbs into her waistband, and slid off her panties. She had an adorable round butt, which was covered in goosebumps. She turned back around, revealing closely trimmed but otherwise naturally growing red pubes. Underneath was a pronounced set of pink pussy lips that peeked out from between her tightly closed legs.

Now it was my turn, but as I reached for my boxers, Jessica told me to wait. She ran out of the room and shouted up the basement stairs: “The house boy is about to get naked!”

I immediately heard footsteps thundering through the house as the other 4 housies came rushing downstairs. They burst through the basement door and packed into the room, giggling and smiling. As soon as they saw me in my underwear, I heard whistles and catcalls.

“Go on! Lose the underpants!” said one.

“Yeah, let’s see that cock!” said another.

I took a deep breath and pulled down the boxers. There was another wave of catcalls as all eyes in the room fell on my dick. I was made to do a turn so that everyone could get a good view. I was blushing harder than Claire had been, and it seemed a lot warmer in that basement. Claire herself wasn’t making a peep, but she was staring just as intently as the other sisters. I was thankful that I’d bothered to keep up my grooming habits.

“I want a real show,” said Amber. She walked up behind Claire and grabbed a handful of each breast. She grimaced playfully and began squeezing and kneading them, while Claire squirmed in her grasp.

I’d been struggling to keep myself “relaxed” up to now, but that sight was too much. My dick quickly swelled to full size, and there was a round of applause from the room. The sisters began shouting lewd commentary as I throbbed in front of them.

“Very impressive.”

“That’s a cock that looks like it enjoys a good sucking.”

“Definitely. That cock would be at home with a pair of lips wrapped around it.”

“Or two pairs of lips!”

“I bet that sucker knows how to please a pussy.”

“Those balls look like they’re fun to play with, too.”

“It’s about time we saw some cock. He’s seen my pussy enough times.” That comment got much agreement from around the room.

“What do you think, Claire?” joked Amber as she continued to grope her.

She didn’t need to ask. When I glanced back at Claire, I could see that she’d gotten noticeably flushed between the legs. Her nakedness left her arousal as obvious as mine. A couple of the sisters noticed as well.

“Oh yeah, she approves.”

“Want to touch it? It won’t bite!”

“I think it likes you!”

“I know what she’ll be doing later,” said Amber. She made a rubbing motion below Claire’s belly button.

Finally, the celebration began to subside, and the sisters began to trickle out of the room. Claire and I took our chance and began hastily putting our clothes back on. We caught each other’s eyes and couldn’t help but smile.

As Lisa was leaving, she gave my bare butt a slap. “I’m down any time you want a rematch, house boy,” she said.

After Ashley’s bathroom stunt, the housies became even more bold with their teasing. Things began to escalate to a whole new level. But throughout it all, everyone maintained the pretense that it was all perfectly normal. When a completely naked housie marched past me on her way to the bathroom, she’d say hi to me as if we were meeting in the hallway at school, and I’d have to pretend I wasn’t looking at her bouncing breasts and jiggling butt.

One day, two roommates, Lisa and Jessica, called me into their room to help them rearrange their furniture. Lisa and Jessica were both on the women’s soccer team and were in great shape. When I knocked on the door and entered the room, they were already inside waiting for me. The baggy t-shirts they wore were not quite long enough to hide that they were both bottomless. I could catch a glimpse of pussy peeking out from underneath the white cotton fabric. I noticed the indent of panty lines on their butts, which meant they had actually been wearing panties just moments before and stripped them off as soon as I knocked on the door.

“Helping” them rearrange their furniture turned out to mean doing it for them while they lounged around and directed me. Occasionally they’d bend over to move backpacks or sports equipment out of the way, and I’d get a nice view between their legs. I quickly learned that both girls were clean shaved. Lisa’s lips were tightly closed, forming only a thin line. Jessica’s lips were more open and showed off her pink labia and clit. I also got nice views from the front whenever they’d reach up to move something onto a shelf. It took nearly 20 minutes to finally get the furniture the way they wanted. It probably would have been faster if I hadn’t been so distracted by the constant pussy flashing. After I finished, they each flopped onto their beds with satisfaction, causing their shirts to flip up to their lower backs and giving me an excellent view of their toned butts. By the time they shooed me out, I’d been hard for so long it almost hurt.

Another day, I entered a room to vacuum to discover three housies inside, Sarah, Amanda, and Brittany. Sarah was about to show off a bunch of bikinis she’d just bought during a winter clearance sale to the other two girls. As soon as I came inside, I was eagerly invited to join them. I sat down on the bed next to Amanda and Brittany, who were actually dressed for once. Sarah was only wearing a silk robe, which she quickly slipped off, revealing her naked body. She had a narrow waist with several small beauty marks spread across her pale skin. Her breasts were lemon-shaped with nipples that were just as pale as her skin. Her pubes were cut into a triangle shape, which pointed down to her pussy.

The shopping bag filled with bikinis was on the floor behind her, so she turned and bent over in front of us to dig for her first set. Amanda let out a whistle, and Sarah playfully wiggled her butt for us. My heart was already pounding. Sarah found the set she wanted to try first, a red one with white flowers. Amanda and Brittany approved, and I was invited to opine was well. I tried to play it cool, but I don’t think I did a good job, as everything I said elicited a fit of giggles from the three girls. When she was done modeling, Sarah pulled off the bikini and bent over to get another set. The constant cycle of stripping and bending over was almost too much for me to take. At one point, Brittany declared that one of the bikinis might look good on her. Sarah invited her to try it on, so Brittany pulled off per shirt and shorts and stepped over to Sarah, completely naked. Sarah took off the bikini in question and handed it over. Once Brittany tried it on, she decided she didn’t like it after all. She took it off and tossed it back into the bag. She didn’t put her clothes back on before she sat down next to me, so for the rest of the bikini try-on I was sitting right next to a naked woman. I tried not to glance at her generous breasts with large areolas and cone-shaped nipples.

I was there for almost an hour before Sarah finally tried on her last set. The girls would constantly get distracted from the try-on and begin chatting about other topics, and the whole time I’d be trying not to stare at all of breasts and pussies only feet away from me. Regarding my opinion on the bikinis, I don’t think I offered anything useful to the conversation, but I was invited to offer feedback the next time one of the girls went shopping. Brittany even winked and said that a lingerie sale was coming up, which led to another giggle fit.

Another episode was when the housies recruited me bartend for the afterparty for the sorority’s annual costume party. About a third of the sorority was there, which included many sisters who were not housies. My job was pretty easy, because I was only provided with enough ingredients to mix 3 or 4 different cocktails. The sisters were already pretty buzzed when the party started at 1am, and they were all dressed in the standard assortment of “sexy” girls’ costumes. I myself was still wearing the store-bought Robin Hood outfit I’d worn to the custom party.

But then one of them decided to ask me which of the costumes I thought was the sexiest. Before I could say anything, all the sisters within earshot had jumped into the conversation. Soon, the whole party had decided I was judging a sexy contest. One-by-one, the sisters paraded past the bar while the rest of the them catcalled from the edges of the room. Each of them gave a sexy flourish, such as a butt slap or hip swing. Things escalated when Amber, the first housie to show off, took her turn. She was dressed as a sexy devil, wearing red lingerie with red stockings and bustier. When she reached the center of the floor, she bent over and slipped off her panties and threw them onto the bar. She had actually dyed per pubic hair red! The whole room erupted into cheers and catcalls as she arched her back and ran a hand up her butt.

The girl after Amber wasn’t a housie, and wasn’t used to me seeing her naked, but the party atmosphere and booze made her bold enough to spice things up. She was dressed as Supergirl, and when she reached the middle of the room, she reached under her skirt and slipped off her panties. She gave an erotic hip thrust, causing her skirt to swish almost high enough to see underneath. The girls after her followed her lead. The next girl was dressed as a witch, and when it was her turn, she pulled down her top and flashed her breasts. Both of her nipples had ring piercings. The girl after that was dressed as a pirate queen, and lifted her skirt to flash her butt. Underneath she was wearing a black g-string, and a skull-and-crossbones sticker was stuck to her left cheek. She pulled on the g-string and let it snap back into place. Next came another housie, Ashley. She was dressed as a pervy flasher, and during the party had been wearing a long tan trench coat with modest flesh-colored underwear underneath. When her turn came, she strode to the center of the room and threw open her trench coat. At some point she’d taken off the underwear, leaving herself completely naked underneath. She strode confidently around the edge of the room, holding the coat open for each of the spectating sisters. They all hollered and cheered, and a few even copped a feel. When she circled around to the bar, she shook her breasts at me and grinned.

After the last girl had gone by, I was thankfully spared having to choosing a winner, as the whole room had decided Ashley had the sexiest (and most accurate) costume. I obediently declared her the winner and everyone gave one final round of applause and cheers. The experience of watching over a dozen girls trying to out-sexy each other was exhausting, and when the party died down and sisters began to leave, I slipped towards the door. I needed to get back to my room and give myself some relief. As I was leaving, I ran into Ashley. Her trench coat was still hanging open, but she had put the nude underwear back on. She thanked me for bartending and judging the costume contest. She told me her only regret was forgetting to ask me to compete in the costume contest too.

As usual, I tried to play it cool, but these last words made my blood pressure spike. Despite the long party and late hours, it was a long time before I could get to sleep that night.
