My story with dad's elder brother's wife
In 2017, We had my dad's elder brother's wife [F51] living with us to be with me [19M] as my mom met with an accident and my dad was busy attending her at the hospital and managing his office work. We had quite ample time to come close.
She used to cook nicely and together we watched shows to cut time and used to sleep in my room.
One night while lying together on the bed, her hand moved over my shorts and it rubbed against my crotch, it felt tingling sensations and I got hard, I had weird thoughts and held her wrist and her fingers coiled around my penis, I used it to masturbate. I did for a few minutes and then she pulled her hands back, I got scared and immediately pretended to be asleep, but soon she moved her hands and pulled my shorts to get her hands in and caressed my penis to feel its shape and size in the dark and stroked a couple of times, then she grabbed my penis and moved her pelvis closer to me and got on the side facing me and lifted her one leg up to spread and pulled my penis into her vagina, she tried very hard to get it in but due to her chubby body she could only manage to get my penis head to graze over her labia.
To make things easier, I got up and positioned myself between her legs. She held onto the tight grip from the beginning and guided my penis inside. It slid and went in all at once, and I found myself inside her. I felt a lot of tickling, and I started thrusting in the same position for a while until I came.
After the coitus, we turned away from each other and went back to sleep. All of this happened in the dark. We couldn't see each other's faces or expressions while doing it.
The next morning I felt shy for what we did, but she didn't even have a single sense of awkwardness towards me as if whatever happened last night she forgot and scolded me for leaving my clothes in washig machine and went out of the room. So, I kept pretending normal as if nothing happened, and we were on our routine for the next 2 weeks.
Then, one afternoon, we both were resting together after lunch, gossiping about stuff, and then suddenly she said, "Close the door and curtains. I don't want anyone to see us." I thought it is a simple request, so I went to close them without having any thoughts, but being my back she was moving her saree all the way up above the waist and called me out, I turned and for the first time her vagina was exposed in front of me, It was hairy but not dense enough to hide her loose labia and a pretty wide pulsating vaginal opening, it looked like a living creature.
None of us said a single word. It was pindrop silence, and there was me standing and she lying with her vagina facing me. I approached her and touched her vagina lips and then the clit, she shook a little then I slid three fingers inside, it was slippery and it seemed she has gone through several waves of mixed sensation and gave me a look to get started sooner.
I pulled down my pants and showed her my penis, she gave it a sight then I got myself between her legs, She separated her legs and got her vagina wide open, I gave her both legs support on my shoulder and I took squatting position and aimed my penis to the vagina orifice and pushed my hips and next moment I was inside her vagina and started fucking, I opened her blouse and bra to see her breasts dangling. It was the first time we fucked in the broad daylight seeing each other's body and face, she had her eyes closed and felt every thrust, I requested to make eye contact so we won't have any regrets or awkwardness after sex. She liked the initiative and ga completely. This got her body relaxed. That day, we had multiple times coitus throughout and one before going to bed.
After this she left all her sorrows and loneliness aside, we kept fucking regularly in various positions around the house, We did doggy, cowgirl/reverse, she moved/shook quite well with her waist while being on top. We even tried having standing sex in the kitchen, but she used got tired soon because of age and her own body weight, so we mostly engaged in missionary and its other variants along.
Usually, she used to break into my room with naked breasts for ice breakers, which I think was smart to not waste any time speaking. During the sex, I used to give hickies on her tits and nipples.
This thing we kept doing for 8 more months until my parents came back. And she went back to her family.
Last year, she was diagnosed with breast cancer. I prayed for her good health. She had to undergo mastectomy, so she got her right breasts removed. And now she is healthy and fine but takes regular medicines. I still visit her occasionally.
We sneaked to have a quickie in her backyard last fall, we indulged in sex after 8 long years, but that deserves another story.
She still casually mentions our activity during conversations. But I don't think we could find some alone time any sooner.
