Trust the process.

Over the next few weeks, Alyssa and Sid did exactly as they said they would. Alyssa would stay at your place every other day, and the other days she would stay at her place, with Sid. The lessons continued, and they diligently send you photos of every lesson. Usually the photos were of Alyssa on her knees with a mouthful of cum, with the caption: "Load of the day!" Sometimes it would state the time she took with it: "This one she sucked out of me in record time, 12 minutes and 23 seconds! -Sid".

Sometimes they sent you videos, either of Alyssa sucking Sid´s massive cock from Sid´s point of view, or the phone propped up on a tripod Alyssa bought specifically for recording Sid alternating between either sucking, or massaging her pussy until she orgasms. All this is supposed to be for your benefit as well as Alyssa´s, so they encouraged you to actually watch all the videos. You didn´t like it at all at first, you stomach always got that weird feeling, because, well, that´s your girlfriend sucking another mans cock, and being pleasured by another man! You know it´s not right, but something is keeping you watching the videos to the end. Maybe it´s because you´re getting to see your girlfriend be sexual, even though it´s with someone else...

On multiple occasions were you going to stop this, tell Alyssa how you really feel about Sid and her getting so intimate every other day. But on the days that she would come and stay with you, she would cuddle you in the nude, and give you hand jobs in the shower, while talking about her lessons with Sid. "With Sid I have to do this with my hand to get him to cum in the shower", and when she lets you cum on her breasts after giving you a hand job in the shower, she says "Sid cums so much he covers my entire breasts....but I also like how you cum, baby!" Making it painfully apparent how little you cum, your load barely covers one breast.

One day, when you were in class, your phone vibrates. It´s a picture of Alyssa, on her knees in front of Sid, with his whole cock all the way down her throat. "She can finally deepthroat me all the way, to the hilt! What an amazing girlfriend you have. -Sid". The next picture was just of her with her mouth open, Sid´s spent cock to the side. "She swallowed all my cum from the deepthroat position, a real cum slut! -Sid" - "Congratulations on such an amazing girlfriend. -Sid".

Still, Alyssa hasn´t given you a blowjob yet, while she gives Sid one every other day, she´s never thought about swallowing any of your cum after a hand job, stating: "I just feel more comfortable doing that with only Sid right now, it feels like I´d be betraying him a little by swallowing any other cum than his, you know? Besides, he has a process, and I´m sure he will tell me when the time is right for us to do that."

You: "Yeah...sure." You pout.

Alyssa: "Don´t be like that, Sid has done so much for us already, and he´s been a perfect gentleman about it. He has never even tried to fuck me with his big cock, even when he totally could! One time when he was making me orgasm by sucking my tits, the head of his cock grazed the side of my pussy, he apologized, even though it happened a few more times, but he was really sorry about it! We owe him a lot, thanks to him you and I have gotten a lot more familiar with each others bodies!"

You: "Yeah, I guess you´re right."

Alyssa: "Of course I am. By the way, since we´re on the subject, Sid mentioned we would be taking the lessons to the next level soon."

You: "Next level?"

Alyssa: "Well yeah, did you think we would be sucking each other off forever? Sid says that since I can deepthroat him now, I´m ready to step it up. And I agree, it feels like we could be doing more."

You: "You´re going to sleep with him??"

Alyssa: "Of course not, silly, that would be cheating. We´re going to be practicing the act of sexual grinding. There would be no penetration, just sliding his cock across the folds of my pussy, until we both cum. That way we can practice different sexual positions without us actually fucking. Isn´t that a great idea?" She says excitedly, holding your hand.

You: "Sure, that sounds okay..." You say, relieved that Sid´s not going to actually sleep with Alyssa.

You: "Should I be present or is this a private lesson again?"

Alyssa: "I feel much more comfortable with you on the other side of the phone, is that alright?"
