Cum, Repeat. Cum, Repeat. Cum, Repeat.

Andrea, still visibly frustrated, mounts you as you continue to lay on the couch. June directs Andrea on what to do. "Principal Foster, I think I know how to fuck my brother" Andrea sarcastically says. June responds back, "is that because you and him have had so much sex before?" That caught Andrea in a tough position. "Well no, not exactly" Andrea mumbles. "Well Andrea, I've been watching him fuck at school for a while now. I think you should be listening to my advice. Now I'm going to record this on my camera. That way you can review this video down the road to see what he liked. I'm sure he'll need your help again. Second, honey, put some effort into it!"

Andrea hovers her pussy over your dick. In one smooth motion she sits down on it. Your penis is now fully inside your sister's vagina. The feeling is intense. She starts bouncing up and down on your cock like a person possessed. It's clearly irritating her that you haven't "cum" just yet. She was going to put on such a show that there was no way you wouldn't drop a load. Little did she know how much semen she'd caused you to shoot so far.

As she moves her hips her tits are swaying back and forth. You appreciate how perfectly formed they are. Watching them shake and bounce is an incredibly erotic sight. So much so that once again, after only a few minutes, you need to shoot another load. You put your arms into the air.

June pretends to trip and fall over onto Andrea. She pushes Andrea down, your dick slips out of her pussy. Andrea is now laying down on top of you. "What the hell?!?!" she exclaims. As June explains that it was an accident caused by her trying to get a certain angle on video, your dick shoots a wad of cum onto the other arm of the couch. June quickly cleans it with the rag then goes back to recording. Andrea actually stays in that position. June slides your dick back into Andrea's pussy. You go back to fucking Andrea; this time her face is inches away from yours. You stare deeply into her eyes as she squeezes her vaginal muscles around your penis.

You figure that you've got all the cum out of your system. You also appreciate June's plan much more now than when she first explained it. In the future you likely would never last more than a minute or two inside your sister. Without the blue pill Andrea would've blown you for a minute, swallowed your load, then been on her way. While you could use your sister anytime to help you cum, June's plan had her full on fucking you and desperately needing your jizz.

As soon as you thought the jizzing was over, Andrea uped the ante. "Oh little brother, I love fucking you" she proclaimed. You and June both smiled upon hearing that. "Oh brother, I've wanted your cock in me for so long" Andrea moaned. After every sentence she'd look at you to see if what she said was working. You pulled together all the self control you had and appeared expressionless. With each statement she made, seeing that you had no reaction, she would make the next statement dirtier. "God I need my brother's cum inside me!" No response to that exclamation. "I was born to be my brother's cock ****!" You remained stone-faced. "I need my little brother's jizz so I can make a baby!" That one...that caused you to break.

You were going to cum once again. Since Andrea was laying over you it was harder to get your hands into the air without it looking weird. You slowly raised them up, shot June a look, then embraced your sister's body.

Your sister was lifting her pussy off of your dick completely, then taking the length of your dick back inside of her. Seeing your signal, as Andrea lifted her vagina off of your dick, June pulled it slightly out of the way. Andrea's pussy plunged down onto your groin. "John, what happened?" Andrea asked. Andrea was about to look back when you grabbed her head and pulled it towards yours. You were now making out with your sister. As your tongue explored her mouth, June simultaneously captured your latest load while explaining the situation to Andrea.

"Oh honey, I'm so sorry, it looks like he went soft for a bit there. I think I was right all along. Oh well, I'm sure I'll be able to get your brother off here in no time at all."

Andrea struggled for a bit then broke your embrace. "The fuck you will" she said. "I'm going to get him to cum. You just fucking watch me." Andrea stands back up and turns around. She spreads her ass cheeks. "Shove it in there June" she proclaimed.
