Homewrecking Sister-in-law: a Present to Remember

You wake up on your birthday morning, the house silent except for the two of us. Your wife is still in bed, but you’re wide awake so you go downstairs… with me – your sister-in-law – following close behind you with a special present for you. I tease you, my hand sliding over your cock through your pajamas, my cleavage on full display. You’re nervous, guilty, but you can’t hide how hard you’re getting for me. Of course you follow me to the guest room. At first, it’s innocent enough – just me stripping while you stroke yourself. But then my hand is on you, my mouth is complimenting your cock, shushing your weak protests. I promise you nobody will ever know. I tease you with my lips and tongue, and it’s so unfair that you’re not giving me a present in return. The walls are paper thin, so you can’t protest too loudly as I mount your married cock and start riding you. I want you to feel dirty, trying to stay quiet while I fuck you.
