Fuck your tied up girlfriend!

You suddenly push away all of your hesitations as you quickly begin removing your clothes. Your cock stands up at full mass as your pants fall down to the floor. You kick them off along with your shoes and socks, then almost tear the buttons from your shirt as you rip it off. You are finally ready.

You move in, guiding your cock to her waiting pussy. As the tip touches her lips, you can already feel how wet she is, you have no problem sliding in.

"MMMhhhmmm!" You hear Olivia's muffled moans as you continue to enter. You place your hands firmly on her thighs as with one quick motion you push yourself completely inside of her. You hear another sound coming from Olivia, this time seeming more like a gasp. You normally take things a bit slower easing into it, but there's something about her being tied up, the freedom for you to do whatever you want, it's a powerful feeling.

Just as quickly as you entered, you pull back, only to slam in again, this time with even more ****. You repeat this again and again, keeping no true rhythm, simply doing what feels the best to you. As you thrust, your eyes keep focusing on her ass. As much as you're enjoying your current act, you wonder what it must feel like to squeeze in between those cheeks. Olivia had always turned you down the times you brought up anal sex, but she can't really stop you now.
