He came, hard.

Suki hadn't expected to be flipped around as Alex had done, but she was his lover, his woman, and this new position, as he rubbed her mons, his cock rigid, throbbing, but unmoving in her, his fingers were doing the work, keeping her orgasmic and spasming around his length, the invading rod motionless, teasing her. "Alex," she begged, "Lover, please. Come in me. Fill me with your lust." Never once through this was the notion she might be fertile entered her mind. In the almost 20 years she'd been married to her husband, they'd never once made a child together, and they suspected, tho Suki never bothered to ask why, or take tests, that she was infertile. Back then that perhaps had been true, but as nothing had ever come of the sex, Suki stopped worrying about condoms, which was why now, as her virile stepson plumbed the depths of her pussy, she didn't think to concern herself with a condom, a diaphragm, or some form of pill.

Feeling her quivering pussy, sucking at his cock, her juices dripping down his balls, and body shivering in pleasure, he felt very proud of his skills. So again he started to slam into her, feeling her orgasm extend as he was ramming into her, the bed rocked and skin slapped skin, juices squishing out of her. He was in ecstasy, it did not take long before he could not hold back any longer. Her quivering cervix open and closing sucking wanting his seed deep inside her, kissing the tip of his cock, he held her hips with both hands.

She would feel her Son's heavy balls lift and clench against her mons, that fat cock kicking up and pulsing.Then perfectly timed with her cervix that hugged and sucked at his tip, a strong thick robe of warm cum shot deep into her, painting the unprotected top of her womb. He held her and kept balls deep, pumping hot load after load into his Mom. Deep squishing squirts pumped into her womb filling it leaving no part untouched. A few months of pent up sexual tension released in a very thick and heavy load of cum filling her and up along his shaft until it squirted out of her and over his balls. "unnnngh you are mine..." he said in a deep grunt.

Suki felt the change in her son as she begged him to come, the pause replaced with thrusting, hard deep thrusts, his hands holding her ass right where he wanted her. Deep inside, her cervix stretched and molded a little, accepting the new cock that battered at her walls, demanding entry to her womb. While that was impossible, her sucking, needy womb would suck up as much cum as he could offer.

She didn't realize just how pent of Alex was, the large fertile load churning in his balls. She felt him cum, the first shot painting the entrance to her womb, marking her as his, only to be followed by several more good shots, one of two lined up perfectly to allow his sperm, millions of active hardy swimmers, to invade her womb. Even as he pumped her full, emptying his balls, the amount of cum more then her pussy could take, oozing around his shaft, onto his balls, coating him in his fertile cream, Suki knew she couldn't resist, knew that she would come back, time and time again. Alex gave her what she wanted, a lover that satisfied her needs.

That her fertility had improved over the years, her body healing and her womb becoming more receptive, never entered her mind. Of all the weeks this month, this was the least safe week of all, the week her body was supposed to ovulate, and now, as millions of sperm began their journey to find an egg, Suki had no idea the risk she'd just taken, if the sperm would survive long enough to reach an egg. But as Alex claimed her, told her he was hers, she softly moaned, "Yes Alex. I am yours."
