I was very horny and wanted to make sure I could have sex that night, so I slipped a Viagra in my husband's beverage at dinner. He is an older man, so erections no longer come naturally to him anymore. I wait and wait, but my husband does not have an erection! I realize that I accidentally mixed the glasses up with his son at dinner! Oh no! I tell my husband not to worry and that I will go talk to him. Then, I go to talk to you (step-son POV). I confess to what happened, and see that you have a prominent erection. I apologize and promise to take care of you. I get on my knees and suck your dick. I allow you to cum in my mouth, and spit the cum on my tits. Afterwards, you are still hard! I forgot what it was like to fuck a younger man since my husband is significantly older than twenty. I offer you my pussy, while laying on my back in panties and high heels. I let you fuck me, moaning on my back and then riding you with my big tits jiggling in your face. You cum inside my pussy, now your second cum of the evening. I wipe up the cum with my panties and let you keep them. Don't tell your father! Mommy dirty talk & cock worship.
