My adoptive mom and I have been secretly having an affair

(from REDDIT!!!!)

This started last year, when I was 19 and has been something we can't stop doing and don't know what to do anymore.

I was adopted at 15, by two caring rich parents, who already had two boys of their own, both older than me. I went from being rebellious and badly behaved into shy and quiet. Mainly because of two things: One because they were so much more richer than any family I had stayed with. Two because by the second year of staying with them, they wanted to adopt me.

It was mainly because I had a really good relationship with my adoptive mom. She was half Cuban and British and a retired business woman. She made sure that I was happy and doing well in school. We talked a lot together and she said she loved all her kids the same. But it was pretty obvious I was her favourite. My two older brothers said it was because I was the youngest but also she had retired pretty early to make sure I had a good education.

It was after a while when Dad decided to 'spend more time at work' when we got really close. By then both my brothers had moved out and my parents were getting into a lot of arguments. They were mainly complaints from my Dad and he spend more time away from Mom. I had always found my Mom to be beautiful and smart, but around this time I began to feel she was sexy and I noticed her DDs and curved body.

It was one night when I found my Mom, alone crying at her desk in front of the mirror. She was all dressed up in a beautiful summer dress and was drinking red wine. I hugged her from behind as she broke down in tears. "He's been cheating on me this whole fucking time" I stared at my Mom through the mirror because she never swore even when pissed off at us. "I can't believe it, I saw the pictures on his phone, what do I have that she doesn't?"

"Mom don't worry, we get through this together" She looks up at me drying her eyes she asks me to unzip her dress from the back. I unzip the top and she instantly pulls it down revealing her huge tits. She was wearing a thin laced bra, and then with her eyes still on me, she pushed against her bra to make her breasts look bigger. "Is that not big enough for him?" "Wait what?, Mom?"

She didn't reply and she spins her chair around so she is sitting directly in front of my growing boner. She gets up and tells me to sit down. As I sit, she removes her dress to reveal her body. Mom removed her bra and looking down at me she lifted her jugs up. "You missed on sucking on these, right?" I didn't reply as I tried to cover my boner and Mom slowly bent down and sat on my lap facing me.

She kissed me, moistening my mouth, before bringing her left tit to my mouth. I suck on the milky tips as she moans in pleasure and she goes back to kissing me.

Turning around she moved her ass further on to my lap and she takes my hand and slips it in her panties. She turns her head as we continue kissing as I rub her pussy. I feel around, she has a thin bush, right above her clit, and after playing with it, I slip my hand inside. Her insides were inside, as her lips opened up. After Mom had split her legs there was enough space to fit all my fingers. She moaned as I fingered her and my right hand reached out and played with her tits as she dirty talked me in between kisses. "You like that Mom?" She moaned in approval as I finger fucked her quicker. She turned so she could take off my clothes and after we returned to what we were doing. I slid my fingers in and out till she sprayed on me. I opened her panties so she released it all over me. We made out for a while before she slipped my cock in her lips. "I'm going to fuck you baby" She climbed up and forced herself down on my cock. Her lips were gaping open and within minutes I pulled out and cummed on her stomach and breasts. We were panting and exhausted as Mom sat down on my lap and stared into my eyes. My dick lay flaccid in her hands as she jerked the final drop of cum out.

The next morning, she apologised for what happened and said it was her fault and to forget it ever happened but it happened again the next week on holiday.
