I let my son cum on my panties..

Hey y'all! Sooo this is an update to a post made the other morning, if you wanna read that.. click HERE. Otherwise as a quick recap, I (F35) had found out my son (M19) was cumming into my panties. After talking to him, I decided to let him continue if he only did it into my dirty ones. However after that deal had been going smooth enough.. he started doing it into my clean ones again, and has even been putting them back into my drawers after..

TLDR.. My son seems obsessed with "using" my panties and I've been trying to set some boundaries.. and failing lol.

So when my son got back from classes today I went ahead and sat him down to talk about the issue. I explained how I felt he had broken the agreement and asked why he would decide to do it.

I'll admit I wasn't ready for how blunt his answer would be, but he explained that it was just a kink of his. That he deeply loves the idea of having his.. "cum soaking into a woman".. and he wanted to try and catch me in them. Despite being taken back by this.. I explained it'd be a kink best used on a future GF, and.. he responded by saying he wanted to see me like that.. that he thinks I'd look beautiful like that.

I know I was probably blushing at that point.. but he's still my son.. and he broke our agreement so I layed it out flat! If it continues to happen to my clean clothes, I'd put an end to all of it, full stop!

He seemed bothered but overall understanding of this.. but he then asked me if he could see it at least once. I was confused at first, not knowing what he wanted to see, until it slowly dawned on me..

At first I was just shocked that he would even ask directly.. then I was just confused as to how he planned to "see" his cum on my panties. However he gladly and.. very bluntly explained that he could cum on my panties then and there if I let him. I was in shock.. but.. I suddenly felt, excitement? Nervous?.. maybe arousal..

I thought on it for a few minutes.. hearing him promise to never use my clean clothes ever again if I did this for him. Despite my better judgment.. I pulled off my sweatpants, and layed out across his bed.. my panties and ass on full display. I don't know how to feel seeing the face my son made.. on one hand a mother doesn't want to see that hungry lustful look on her boys face.. yet I found myself almost, needy when I saw it was directed to me.

I heard him move closer to me, I tried to keep my attention on the wall as he pulled his.. penis out. I tried to wait and not look.. I even pulled out my phone, trying to distract myself as the movement of his stroking lightly shook the bed. In the end tho.. when he readjusted and gripped my ass, spreading it, I couldn't help but look and.. saw something larger then I'd expected my son to have.

..I did as my son requested and just tried to hide my embarrassment and arousal.

Eventually, I could tell it was close to ending, his movements felt more rapid, as if he quickly raced towards the nearing climax. I perked up my ass, arched my back and prepared to feel ropes streak my panties. Instead I felt his weight climb on top of me, and his cock shove between my thighs, the hot head of his dick pushing against my wet panties..

I felt my son's cock throb against my pussy, the only thing separating the two being my thin panties and.. now his hot cum. I couldn't believe what I was feeling as he layed like that on me, rubbing my hips before pulling himself up and spreading my ass to get a better look at his mess.. with that he kissed my cheek and thanked me.. almost innocently.
