Stepmom Was Asking for It

It's stepMom's birthday and you've hosted her a big party but she's starting to get messy so you convince her it's time to go home. You help her into her PJs but she's having none of it. She hoped she'd end up in someone else's bed tonight, and she's feeling horny. She teases you about the hard-on you got when she stumbled into you earlier, and suggests you help her get the birthday sex she needs. Horrified at the idea of your stepmom coming on to you, you reject her. But she's persistent and manages to get your pants down. Your hard cock gives your true feelings away and as she sucks on you, all morals and willpower leave your body. You give in to temptation, fucking your stepmother senseless. After you cum inside her, she asks you to stay, and you oblige without second thought. Your cock getting hard again already as you press up against her, all kinds of dark thoughts are running through your mind. Now that she's opened this door, you're not sure you can close it again...
