[This was a custom request] Your stepmom has been secretly lusting after you and she finally admits it one evening in your bedroom while your father is downstairs resting. She's noticed how big your cock is when you get out of the shower... and she's feeling quite unsatisfied with her older husband. Plus, being closer to your age herself - she wants a son or daughter of her own and her husband isn't able to give her that. She purposely hasn't worn any underwear and eagerly shows off her tight little body while begging for your seed in her belly. You can't help but get hard and pull out your cock for her. She is impressed with its size and can't wait to get it inside her. You fuck her deep and hard while she's in the prime breeding position and constantly begging for your seed - for your offspring inside her. She gets so creamy around your big cock and cums super hard before letting you fill her with cum and impregnate her.
