You cant replace mommy

Mommy and you used to fuck around every Friday after step-dad leaves for the bar but recently you've been seeing a girl and have a date planned with her Friday. Mommy walks in, wearing lace lingerie with crotchless panties. She's mid sentence and realizes you're getting ready to leave. She's confused because it's Friday, you tell her you have a date. This makes her frustrated and abit angry, you didn't tell her about a girl. She makes it clear that you're not going to just forget about her, you're not going anywhere. She shows off for you and pushes you on the bed. Sucking your cock, then makes you eat her pussy and ass. She tells you to fuck her but you ask about a condom... she tells you no more condoms, you're going to get mommy pregnant so you can never ever leave. You fuck her missionary then she rides you, you're about to cum but she doesn't let you. You can't last any longer so she begs for you to impregnate her.
