Pool Party 2: Sisters [inc, nc, oral, futa, exh]

**Please read part one, I’ll link it in the comments. If you don’t, a lot of this won’t make much sense.**

After the party, everything went fairly well. Katie and Cameron talked for a bit and they found out they were going to the same college. However, Cameron would be moving in early to an off-campus dorm right after graduation next week, and she offered for Katie to fill a roommate slot at the end of the Summer. Katie knew she would miss her over the summer, but she was excited at the idea of Cameron as a roommate. After that, Katie paid the DJ and caterer, made sure there weren’t any big messes, and thanked everyone as they left. It wasn’t until they started leaving that Katie realized she never got dressed, and a few guests asked to touch her cock, just to see if it was real. She smiled politely and gave them permission, it was nice to feel confident about it for once. Cameron was the last to leave, and she kissed Katie on her way out. Sometime in all the commotion, Karen had left the patio and locked herself in her room. Katie decided not to bother with it, and so she showered and went to bed.

The next morning, Sunday, Katie woke up and wondered if the night before had only been a dream. She realized it couldn’t have been when she looked at her naked body in the mirror and felt confidence and pride rather than the usual shame. As she pondered what to wear, her phone rang, and her parents told her they would be spending another week in Bora Bora, but they promised to be back on Saturday for graduation. That’s when she decided to wear nothing at all. She strutted into the living room, cock swinging back and forth, to find her sister watching TV on the couch in a tank top and booty shorts. Her eyes looked over to Katie’s cock, communicating both fear and arousal. “Are you just gonna walk around naked from now on?” “Yeah, I think I will,” Katie proudly announced. She finally had the upper hand in their relationship. She thought for a moment whether she should abuse this newfound power… *Yes. Yes I should.*

Katie sashayed over to her sister, and stood between her and the TV. “Hey sis, I thought you might like some breakfast,” Katie said with a mischievous grin. Karen looked her in the eyes, then looked at her cock and defeatedly said, “okay.” Katie was half-joking and didn’t expect that to work, but the surprise caused her to harden a little. She stepped forward into Karen’s reach. Karen leaned forward and lifted Katie’s cock to put its head in her mouth. It must’ve weighed ten pounds! It started to grow as Karen worked her tongue, and was soon nearly twice its flaccid size. Karen made eye contact with Katie, and wouldn’t stop until the job was one. Her eyes didn’t look hateful as much as they usually did, maybe remorseful? But Katie wasn’t going to let that ruin her good time. She put one hand on her hip and one on the back of her sister’s head as the sucking continued. Karen was way too good at this. Much sooner than Katie expected, she began to cum, and Karen didn’t remove her mouth from the cock until she had swallowed every last drop of it. She sat back in her previous position and said, “can I watch TV now?”

This was pathetic. Katie never meant to turn her sister into a submissive little bitch, but thinking back on all the terrible things Karen had done over the years, she figured it was worth it. In fact, she managed to get two or three more excellent blowjobs from her sister that day. The last one she got from her just before she went to bed. Right before she was about to cum, Katie said, “this time I wanna cum on your face.” Karen pulled her mouth off of Katie’s cock, and allowed 5 thick shots of cum to cover her face, and run down her neck and onto her shirt. “Ah, thanks, sis!” Katie mocked, and she was off to bed. She leaned around the corner once more, “Oh, and I guess I’ll see you in the morning,” she said with a wink. Since they were seniors, they weren’t required to attend school the week before graduation, and Karen wouldn’t choose to go back to school on her own, not after the shamefest that was Saturday night. Katie had her all to her own, all week long. She comforted herself with that thought as she snuggled into bed, one hand lightly caressing her boob. Suddenly the light switched on, and Karen was standing in her doorway with a strange look in her eyes.

“Look, I know haven’t always been the best sister, sometimes I might’ve been the worst, but I’ve thought about it and, I really am sorry. Not just for what I did to you last night, but for always stealing the spotlight from you. I never knew what you were going through all those years, and I can’t imagine what it must’ve been like, I just… I’m sorry,” and with that, she walked out. Katie was shocked, a real apology from her evil sister? Maybe she changed… Maybe Katie hurt her that badly… Just as Katie started to feel guilty, Karen leaned back in and said, meekly, “oh, and, umm, I think I might like umm…” She struggled with the absurdity of her words. “I think if you gave me more time to get ready, I might really like having sex with you again… sometime.” Then she turned the light off and left for real. Katie had nothing to say, so she just laid back down on her pillow and tried to go to sleep. Things were about to change around here.

The next morning, Katie got up, decided not to get dressed again, and strutted into the living room. This time Karen wasn’t there, so she sat on the couch and turned the TV on. It was on some car movie with girls prancing around in skimpy bikinis. Katie felt her cock engorging, and soon it was standing up in her lap, all 14 inches of it. As she was admiring herself, Karen walked into the room, also completely naked, her pussy dripping, she had clearly been masturbating. Katie’s cock twitched hard, slapping against her stomach. “What are you-” Katie started to ask, but Karen interrupted her. “I meant what I said last night, and I hope one day I can convince you to forgive me. Besides,” she smirked, “you’re gonna need some practice before you move in with Cameron in three months.” She swayed sexily as she approached Katie, put one foot on the couch, and positioned her soaking we pussy right on top of Katie’s cock. Her juices ran down Katie’s shaft, and Katie looked up to her and said, “you don’t have to do this.” “I know.”

Karen began to slide down her sister’s massive shaft, and her pussy was much more accepting this time, though there was still some noticeable stretching. She tried hard not to moan, and failed, with each additional inch feeling like it would either make her orgasm instantly or split her in half. As she reached the bottom, she put both knees on the couch, one on either side of Katie, and began to ride her sister like there was no tomorrow. She bounced up and down, and each time she reached the bottom she felt like she might explode with pleasure. Katie was enjoying it too, much more than Saturday night, and she looked her sister in the eyes. This was the moment they both knew they weren’t doing this for any sort of power play anymore, but rather each genuinely enjoyed having sex with the other.

More quickly than Katie would have liked, she panicked and said, “get off, get off, I’m gonna cum!” But Karen didn’t get off. Instead she began to orgasm as well, and Katie could feel her pussy convulsing throughout the entire length of her cock. Katie pumped her sister full of hot cum, over and over, until her balls finally gave up. Karen rolled off to the side and lay on the couch, out of breath. “I thought you said you weren’t on the pill?” Katie said. After several seconds, Karen managed to get out, “I lied.”
