When My Mom Was Sick, It Just Happened.

I'm 18 yo and I live together with my parents. I'm very close with my mom since ever. My dad is an arse pretty much all the time - he just care for himself.

My mom has cancer, she lost her hair through chemo therapy but sh is surviving it- at lest right now. My dad doesn't care shit. So I do all the caring for her ( mostly emotional)

We are watching TV until night because she can't sleep well atm.

This happend one week ago. We watched some trash TV and she had some kind of emotional breakdown. I grabbed her and cuddled with her.

She invited me under her blanked and we just spooned. I felt how it helped her. I caressed her and felt how i got more and more excited. I never was with a girl before. I realized that she didn't wore any pants, just a long shirt. She pressed herself against me as I caressed her hips.

And then it just happend. I got hard and she felt it. I felt her hand on my sleeping pants. She moaned a little. I just did what i thought what was right, I pulled out my cock and she guided it to her well her vagina.

I pushed inside and she moaned. She was really really wet. I came pretty quick.

We kept spooning.

Maybe 30 minutes later i got hard again and we did the same thing again. i didn't really last any longer.

We both fell asleep like that.

We woke up as my dad went to bed. I was shaking but he didn't realized anything.
So I went up and to my room.

We didn't talked about it, just pretend that this never happened. - I think this is wrong but i really don't know how to engage her.
It feels like she is feeling better now but i really can't tell for sure.

I know that many of you will find this disgusting and in some way I feel the same way, but it just happened.
