My oblivious sister-in-law Donna Sex Stories 2024 – Y2Stories

After a wonderful night of fucking my clueless sister-in-law I convince her to stay again.

Donna had woke up confused , naked and unsure wear she was. After making it to the bathroom she ran a hot bath and soaked for a hour. She grabbed my robe and followed the smell of bacon down the steps. She sat down and told me good morning not know time and date. God Kent she says, I can’t seem to think . So I filled in all the blanks, Donna had no idea of happened outside of the bath she just took. She didn’t know why she hurt or was so confused. Donna drank her coffee and ate breakfast with me.

She only knew that she was to visit with her sister and was to travel last night to see her. After Donna’s husband had left her, Kath pushed me to help Donna out when she needed it. Donna has always had a soft spot for me she always accepted my help. She could not resist my influences even though she knew better. She had told her girls that their uncle was a bad influence on her. She had always been jealous of her sister because how good of sex life we shared . Things change from that time that she accidently walked in when I was showering and saw my erected size. Soon a sexual bond was starting to form between her and me. there were a lot of times that I spent weekends with Donna and her girls. Things happen, frustrations develop, one thing leads to another and I end up drugging and fucking my sister-in-law for over three years now.

What is so amazing is that Donna has remain completely oblivious to me fucking her. This last year both of my nieces caught me in the act. They got excited by seeing me do the deed to their mom that they wanted me to do them. Against better judgement I fucked both and made them stay silent to the deed. Donna is now 35 , I find her so damn beautiful and sexy the older she has gotten. Last night was so wonderful that I fucked her over three time and I find myself looking at her that I want more. I look at Donna and convince her into soaking in my hot tub, I tell her that Kath did not know that she was here, she could go there tomorrow, how often do you see me. My sister-in-law can’t resist me and finally agree.

Donna gets up slowly , I find one of Kath’s bikini’s and Donna goes to the bathroom to put it on. I slip on a pair of boxers and then join Donna in the tub. We talk , Donna did not know why her sister is not working to resolve this differences. I told Donna that I know and that I miss Kath and that I also have missed her Donna. Donna blushed a little then leaned back enjoying the hot water swirling about her abused body. I got up and noticed Donna catching a look at the budge in my pants. In a few minutes I was back with two large old fashions, I handed one to Donna, she gave me a funny look, Its a little early for this ,don’t you think. I gave her a laugh , It what help with your hangover dear I said. Donna took a big drink. She always takes my suggestions . I had spiked her drink with 3 Ambien , Donna would be my sex toy for the rest of the day.

Donna was always a fast drinker, she had the drink gone in 20 minutes. She was starting to feel no pain. She laugh as her words slurred, her legs were bumping against mine . I reached under the water toughing her knee and thigh with my hand. Donna shifted tight against my side , I could feel her starting to sway. I ran my hand up her thigh until I felt the crotch of her bikini’s Donna shivered and mumbled something. I wiggled her crotch to the side slipping a finger into her hot wet hole . Donna jumped from the shock of my finger fucking her cunt, she began swaying and started to moan the deeper I went . I covered her mouth with mine sucking her tongue and sinking mine into hers. I kissed her deeply while I continued to finger fuck her.

I then got up and pulled my oblivious sister-in-law with me . She could not stand so I picked her and carry her over to the day bed. I got Donna out of her wet bikini and stepped out of my boxers. She was now sprawled out on the bed. I started to eat her out sucking on that thick large clit of hers. Then all the while sucking her clit I finger fucked her to a body shaking climax. Hot fluids sprayed from her, I rolled her over on her stomach and picked up her ass. I slowing sank my hard throbbing cock into Donna’s very hot vagina. I love how her cunt lips wrapped around my shaft following it in and out of her vagina. I reached down in front squeezing both breasts with my hands as I pump hard into her. Her face shoved into the pillow moaning as my cocks head hammers deep against her cervix . I grab her hips as I hammer her hard . I start to come I can feel my sperm spaying hard against her cervix into her womb. As my cock pumps its seed into her her vagina spasms and contracts tight around me. Exhausted I push Donna flat on the bed and stay total embedded in her.

After a rest I take my sex toy up to my bedroom , her body life less swayed back and forth on the way up stairs. I dropped Donna on the bed rolling her on the stomach. I then began fucking her in the ass. Donnas body was getting use to my large cock . I was sliding in and out easier than last night. I fuck her hard and fast till I was about to come. I pulled out and drove hard into her wet vagina hitting her hard cervix which cause me to explode deep inside her again. It was about noon that I had drugged Donna. I figured that she would be my toy for the next eight hours yet which gets me to around 2 am. I get up to rest and get a drink.

I continue to fuck her at 4pm starting with her mouth and again ending in her vagina driving her cervix and womb deeper into her stomach as the full 9 inches sink into her. I go have a bite to eat then come back in a few hours after I recouped. Poor Donna was looking a bit worn, a pool of my sperm flooded between her thighs, her vagina red and raw. But I kept on fucking her the rest of the night. About 2 am she was tossing about so I gave her another Ambien which got her through to morning. She woke around 7 am confused , not knowing time where she was . She stood swaying back and forth my sperm draining in globs from her red sore cunt. She tried to walk but her legs shook and I had to help her to the bath. I ran the hot water while she sat on the toilet trying to pee. She moaned as the pee burned her lips and come drained steadily. I help her in the tub where she soak a long time.

Again by the time Donna came down she was total confused . Her head pounded, ass, vagina, and stomach all hurt. She did not know why and after eating she needed to lay down. After a long rest Donna decided that she was coming down with something and should go back home . She would have to see Kath another week-end. I would look forward to that and maybe pay my sister-in-law a visit to her house. Any how my clueless sister-in-law had no idea of what I did to her again. I wish I could find some other girl or lady that could convert that easily into a sex toy , I be happy happy.
