Cumming Under Surveillance

June guided your dick into your sister's waiting asshole. It took a minute or two for the head of your cock to penetrate her butt. Soon though, the length of your penis was inside your sister's ass. Even though you fucked Cindy and Miss Kroll's asses earlier today, somehow your sister's butt was far and away better than both of theirs.

Just like when she was fucking you with her pussy, your sister was giving it her all as her ass fucked your dick. She grinded her ass on your groin, lifted it up then plunged it down, even spread her ass cheeks so you could get the best possible view. The only problem was how she was situated. Since her back was to you she was turning around to gauge your reaction to things. Your dick was in her line of sight meaning that you couldn't get away with the slight of hand trickery that had gotten you this far.

As your balls somehow started to fill once again, you panicked. This had been far and away the greatest experience of your life. Still, you didn't want it to end. You shot your arms back up into the air. June gave you a look indicating she was out of options now that your dick was being actively looked at. You raced through your mind for a minute before coming up with a solution.

"Lesbian! Lesbian!" you yelled as you pointed at your sister and your principal. June, reading the signal, took Andrea's head into her hands and began passionately making out with her. Not only was that scene incredibly hot, but it took your sister's attention away from your dick. You "accidentally" slipped out of your sister's asshole, quickly came into your hand, then moved your dick back inside her ass.

You thought June would be mad at you for forcing her into a lesbian act with your sister. Instead, she seemed to enjoy what was happening. Even when she could've broken the kiss with your sister she didn't. She knew you didn't "need" to see a lesbian act to cum, why was she still making out with your sister?

After a few more minutes of ass fucking June finally ended the kiss. "Andrea" she said in a calming voice, "nothing seems to be working. Let's just call it a day." She guides her ass off of your dick. Your still rock hard despite cumming numerous times over the last half an hour.

Principal Foster takes Andrea's place on the couch. "Andrea, let's see if it truly is a problem with his dick" June proposes. She kneels between your dick and takes your cock into her mouth. She gives it everything she has. The feeling is great; not as good as your sister's mouth but still enjoyable. In addition, she is sucking a dick that was just inside of your sister's ass. It felt good but after the marathon cumming session you just had it wasn't enough to get you to spray any more seed.

As the minutes passed, Andrea started smiling wider and wider. It seemed she was being vindicated. In a last ditch move June slipped a finger beneath your dick. She started pressing it against your asshole while she continued to blow you using all the tricks she had. That.....that felt great. As she moved her finger inside your ass your sack started to fill. You pulled your dick out of June's mouth and came on her face.

"Alright, that solves it! I guess John just isn't into his sister. Oh well Andrea, can't win em all" June gloats with your cum running down her face. Andrea can't even form words she's embarrassed. She angrily mumbles to herself as she starts to put her clothes back on. As soon as she finishes she stomps out of June's house; slamming the door on the way to her car.

June took a seat on the recliner across from the couch you were on. "Damn John, how many times did you cum? I would think after all the fucking you've done you could last a little longer. You must really want your sister!" Laying there exhausted, you only manage a nod in agreement.

"Well now that bitch went from thinking she was hot shit to being embarrassed that she can't even get her own brother off. Serves her right for what she did to my nephew."
