Calor infernal

The heat was too strong, 50 degrees, my mother and sister were sleeping in their respective rooms, suddenly the light went out, my room was the only one where the ventilation continued to function. Both came to sleep on my bed, it's too big for me alone, they both wore a transparent nightgown with which they got into my bed, my mother on the left side and Sabrina my sister on the right side. Suddenly the ventilation also stopped working, I fell asleep again, when I woke up again both were without their nightgowns, only in lingerie. Brina was lying face down, she had a lycra boxer on which her buttocks could be seen perfectly, her breasts were bare and free to touch, I touched her nipples, she opened one eye and gave me a wink, I took it as if she wanted me to touch her more, I started licking her nipples, slowly making my way down her chest until I reached her abdomen and then her virgin cave, introducing my finger into her vaginal lips, the entrance was difficult, I had to put and take my finger several times until her cave began to moisten, my sister made gestures of pleasure, so I did it for about 5 minutes. Then I left Brina and she turned over onto her back towards me, spreading her legs, obeying all my instructions, I placed my hand on her right leg, pulled out my cock through the boxer hole, directed it towards her rosie cave, slowly entering only a little more than the glans when I noticed I had reached her virginity, I said you're a virgin sister, that's good. I pulled out my penis from her interior and introduced it again, this time a bit stronger, now my whole penis was in, Brina let out a small cry of pain, I took her pillow and bit it to avoid waking up our mother as she was being deflowered... meter and pull out, her vagina was very tight I felt like it was squeezing my cock with its vaginal walls at the same time she felt greater pleasure, she was launching soft moans so as not to wake up mom, it didn't take more than 5 minutes when a cry of pleasure came out, my sister was about to come to orgasm so I penetrated harder, managed to ejaculate inside her and Brina had a mega orgasm, her vagina contracting with my cock inside, both of us launched moans that our mother would have heard. After finishing sex, I pulled out my penis from her interior and stayed embracing her, both of us naked. Brina: That was delicious you deflowered me, I loved the sensation of having you inside. Me: That was delicious deflowering you, your vagina is very tight and gives more pleasure when penetrated. Like that, embracing each other, I whispered in her ear that I wanted to put my cock in now like a puppy, she agreed, sat on the edge of the bed with her ass up, so I rubbed my flaccid cock over her vaginal lips for her to have an erection from the touch of her skin and it happened. My cock went back to being hard, with my tongue I gave some licks to her vaginal lips, in that instant she said-ay that was delicious, I put my finger all the way to the bottom and made circular movements inside her vagina, little by little it started getting wet, I put my finger in and out, her vagina got more lubricated, I took my erect penis and rubbed her vaginal lips with my glans, she asked me to put my cock in already, so I did, I put all my piece of flesh in one go, Brina was biting her lips from pleasure, I started fucking her hard for a few minutes until she launched an ayyy I'm coming, I came, then her vagina contracted and her legs got stiff, at the same time I came inside her. It was already 5:00 AM, just a few minutes before mom would wake up to go to work since my mother gets up at 5:20 AM, which gave us time to have sex and come before mom woke up. Two months later Brina told me that she is Pregnant but the baby is a friend's.
