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 **** 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 ****, 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 **** and start riding you. I want you to feel dirty, trying to stay quiet while I **** you. You’re betraying your wife on your birthday, committing adultery inside my glorious ***** without a condom. The guiltier you feel, the more excited you get, and I feel you losing control.
You beg me not to let you *** inside me, the betrayal would be too much, and I promise I’ll hop off at the last second… right after you make me ***. I take my time, feeling you tense up, knowing you desperately want to explode inside me. I tease you about it as I ******, but I keep riding. You try to pull out, but a dirty cheating husband who can’t resist doesn’t get a say. I want your *** deep inside me. I want your wife betrayed. I want to see the guilt in your eyes when you lose control and fill me with your seed, not hers. And no, there’s no birth control.
You can’t fight it anymore. You explode so hard and so long inside me as I whisper that I own you now, for however long it takes for me to get pregnant.
