Locker room hijinx

Alice and Sam drove to school together, the benefits of being 18-year-old seniors, of course with only three months of school left basically all of the seniors were at least 18. Today was Sam's turn to drive.

They walked into the school and Alice drank in the sight of all of her fellow students. This really is nice, she thought to herself, Some of the guys I never thought anything of are seriously hung, and some of the girls, wow.

"See something you like?" Sam teased.

Alice glanced at Sam, "Yeah, how bout you?"

Sam glanced back at her, "Yeah."

They stopped at their lockers which were, of course, next to each other. All of the seniors had their lockers together, in alphabetical order by last name.

The locker on Alice's other side was occupied by a very shy but cute girl named Maria Sandoval. She was a bit taller than Sam and Alice, 5'5" probably, with beautiful dark skin, black hair, and brown eyes. She had a very sexy face, and when she stepped up to her locker Alice was surprised at how damn sexy her body was in those booty shorts and midriff shirt. Her long hair was pulled back into a ponytail on the top of her head and shimmered as it fell to nearly her butt. Oh and what a butt. It was so round and huge. Alice had never imagined a butt like that could exist without the help of the Rulebook, it was so huge and still completely and utterly sexy.

Alice was having a really hard time keeping focused.

"You see something you like?" Maria said softly.

"Yeah, I do," Alice answered equally softly. "Wanna try my dick out?"

"Only if your sister wants to join us. I want to bury my face in cleavage while you fuck me silly."

Alice was surprised, Maria had never been so forward before. What the hell, some of the rule changes I've made have really strange side effects.

Sam leaned, "I've got keys to the locker room, there's not first period PE." It took Alice a minute to realize in a world where clothes were optional having gendered locker rooms didn't make sense.

"You think you can please me before first period? That's just 15 minutes."

Sam smiled, "My sister can have you on your knees begging for more in 3."

Maria just shut her locker and smiled seductively. Sam and Alice shut theirs too and all but ran to the futanari locker room.

When did Sam get some comfortable with the idea of having a threesome with me? Alice thought to herself. And why am I so turned on by it?

"Thanks for not freaking out about having a threesome with me," Sam whispered as they walked to the locker room.

"It's kinda hot," Alice admitted. She watched Sam's reaction, and saw a hint of desire there.

In the locker room Maria wasted no time pushing Sam down on a bench and up against the wall before pressing her face into Sam's ample breasts.

"Mmmm, that feels nice," Sam purred as Maria slipped one of Sam's nipples into her mouth.

Alice start stroked her dick while she watched her sister get her tit sucked by the sexy Hispanic girl. Damn that is hot. She stopped long enough to line her massive member up with Maria's dark slit, and slowly pushed herself into that delectable pussy. She slowly pushed her whole foot of cock in, and dug her fingers into Maria's thick ass cheeks.

"Oooohhhh," Maria moaned into Sam's boob.

"I told you," Sam smiled.

Alice watched milk start dripping from Sam's free breast, She does lactate! "How's that milk taste Maria?"

The girl broke her mouth free for a moment, "Delicious."

Sam reached up and grabbed her other boob and began playing with her nipple while Maria returned to servicing the other one. Alice slowly pulled her cock back until just the tip was between Maria's dark pussy lips and set a gentle rhythm of in and out.

Alice began to breathe a little harder, it felt so good. She watched Sam slip her free hand to her snatch and start touching herself. Alice felt her heart skip a beat, Am I getting off more on the thought of my sister touching herself than I am from fucking Maria?

"Ooooohhhh," Maria moaned through Sam's breast. Alice realized that she'd picked up the pace without meaning to. She didn't want to slow down now, she didn't have a ton of time and Maria clearly liked it. She liked it too. She continued to slowly build up her pace and **** while Maria continued to keep her face in Sam's breast.

"Uhhhhh, I'm going to cum. I'm going to cum, I'm cumming!" Maria shouted, Alice felt her own load let go at the same time. Her cum flooded out of Maria's pussy and run down her own dick.

Maria slumped down and Alice got a good look at her sister still frantically working her clit. She couldn't help herself, she pulled her cock out of Maria and began desperately stroking it with both hands, she wanted to cum with her sister. Sam moaned as soon as she saw Alice's cock, her hand on her clit speeding up. Alice sped up too, she felt her balls clinch and held it back, forcing her orgasm to build and build.

"Ohhh fuck!" Sam yelled, and Alice felt her balls let go. A huge rope of cum shot out of her cock straight onto Sam's tits, followed by another, and another and another. Alice felt like if she kept stroking she'd keep cumming forever. She wanted to keep cumming on her sister forever. After a blissful eternity she felt the urge subside. She glanced down at her handiwork, both Sam and Maria were covered in cum.

Sam looked up at her dazed, "That was fucking hot."

Maria just lay on the bench whimpering.

"I think I broke Maria," Alice smiled.

"I think you did," Sam said before she licked a huge wad of cum off her breast. "Damn, your cum tastes amazing. I'm pretty sure I could get addicted to this."

"Sam, if you keep doing that you're going to make me too horny to go to class."

Sam grinned, "Yeah, we have English this morning, and Ms. Meadows and she's fucking hot."
