Only time will tell.

They hurried, got breakfast and showered. "...you know, when are we going to have sex in the shower?" Momo teased Izuku with a grin.

"...when I remember to set our alarms an hour earlier so we have time to do so in the morning, or during a weekend when we don't have anything else to do," Izuku suggested with a grin. "...okay, seriously though, why haven't we done that yet?"

"We just never got around to it, I guess?" Ochaco suggested as she stepped out of the bathroom, wiping her body with the towel and not bothering with modesty. "...we could probaly at least shower together though and save time..."

"Good point," Izuku smirked as he went in with Momo.

...

About an hour later, the three arrived outside of the school, and heard a shout. "Hey, guys!" They turned to see Setsuna running up, and barely holding back mischievous grins. They had already agreed to drop subtle hints that gradually got more obvious throughout the day to see how long it took her to realize they were screwing with her.

"Hey, Setsuna, what's up?" Izuku questioned.

"About nine inches upon seeing me, I hope~!" she quipped, looking at the three with a mild blush. She seemed to be trying to figure out how to broach the topic of last night without looking crazy if it didn't actually happen. "So... did you guys have any... odd dreams last night?"

"...no, no odd dreams, why?" Izuku inquired, technically being honest... the dreams were standard procedure with harem recruitment, so they weren't odd from his perspective after all.

"...you sure?" she asked, pouting slightly. "Nothing sexy?"

"...with multiple sexy girlfriends, it would be odd if he didn't have sexy dreams of us," Momo teased, elbowing Izuku playfully.

"...well, nevermind then," Setsuna shrugged. "Forget I asked!" She then headed in, and Izuku could swear he heard her mutter, "Knew it was too good to be true..."

Izuku exchanged a grin with Momo and Ochaco. This was going to be fun.

(Yes, I do plan on Izuku and Setsuna engaging in pranks with each other after this, lol. Any joke suggestions are appreciated!)
