Patchwork quilt
Andrey was 19, studying at a prestigious university to become a lawyer, living in a dormitory, a typical good student. He didn't skip classes, and on weekends he visited his parents, who lived in a small town. Their family wasn't wealthy, living in a two-room Khrushchev-era apartment inherited from his grandmother, where when winter came, it wasn't exactly warm, to put it mildly—it was simply cold.
During one such winter in 2005, he came to his parents' place for the weekend as usual, ate, and was about to go to sleep, but his mother, despite the cold, made him take a shower, saying she had made the bed with clean sheets, and he shouldn't get into a clean bed dirty after a week in the dormitory. When he visited, he slept on the sofa in the living room, while his parents slept in the second room, which served as the bedroom.
But falling asleep wasn't so easy; the room was cold, and one blanket wasn't enough at all. Andrey was already thinking about getting up and looking for clothes in the closets when suddenly his father came out of the parents' bedroom. He closed the bedroom door behind him and turned on the light:
"Can't sleep?... Sorry I woke you, I'm being called in for duty," he said, showing his cell phone in his hand.
"It's okay."
"Very cold?" he said, taking off his warm terrycloth robe and tossing it onto the armchair, and putting on pants and a sweater. "If you want, you can take my robe, and go sleep in my spot, it's warmer there. Just don't wake your mother, she's very tired today."
"Okay," said Andrey, still not moving.
Andrey was about to fall into a sweet sleep under the warm blanket when he felt that "things were taking a bad turn"... The problem was that when he moved closer, his mother's buttocks pressed against his penis; on top of that, the flaps of his father's robe fell open, and as it turned out, his mother was sleeping in a warm but short nightgown without panties, so his penis ended up right between the halves of her buttocks, which were also damp, having sweated under the warm blanket. No matter how hard he tried to calm down and figure out how to move away, his penis quickly began to harden; within a minute he felt hair on its tip, which he guessed was from his mother's buttocks, and another minute later the tip of his penis pressed firmly against her anus. Andrey froze, afraid to move...
He couldn't free himself without his mother feeling it and waking up; his only hope was that the erection would subside and his penis would shrink, and then he could jerk over to the other side, hoping she hadn't felt anything. Minutes dragged on like hours, but the erection didn't subside; on the contrary, it seemed his penis was getting even harder, and from the excitement, pre-ejaculate began to secrete. There was so much pre-ejaculate that at one point he felt it start to flow down the lower half of her buttocks onto his thigh. No matter what he tried to think about, nothing helped, and his mother seemed to have stopped snoring and was sleeping very quietly.
Suddenly, the halves of his mother's buttocks clenched tightly, squeezing his penis:
"God, you haven't wanted me this badly in about 18 years, I guess," she suddenly whispered, and Andrey's breath caught.
He felt her hand slide over the robe, then move her buttocks, arching her back slightly, lifting her left leg a little, and slipping her hand under it, guiding his penis into... herself.
"Ugh," she whispered, slowly impaling herself on him. When his penis was fully inside her, Andrey, unable to restrain himself, instinctively tensed it, and in response, the muscles of her vagina clenched tightly. Then she began, first slowly and then more rhythmically, impaling herself on his penis, still lying on her right side, with her back to him. Moaning quietly, as he understood, so as not to wake her son in the next room... the son she was currently fucking, who lay holding his breath and afraid to move, fighting the strong urge to start moving in rhythm with her.
Suddenly, when his mother once again impaled herself fully and firmly onto his penis, the bedroom door opened, letting in a strip of light. In the doorway, Andrey saw the silhouette of his father:
"Are you lying there?" he asked quietly. Andrey felt the internal muscles of his mother's vagina suddenly tense sharply and strongly, making the situation even worse... he couldn't hold back and started to cum. He came inside his mother, who not only stopped moving but seemed to even stop breathing, realizing who was now "inside" filling her with his juices. "Well, sleep-sleep, don't get up, I'll lie in your spot," his father continued, closing the door behind him.
Silence fell in the room; Andrey felt himself still cumming, the semen kept coming out and coming out. Seconds dragged on like hours, and his penis continued to pulsate, ejecting more and more semen inside his mother's vagina, which still tightly clenched his penis... "Wow, there's a lot of cum today," Andrey thought, and remembered that he hadn't masturbated in two weeks...
