She joins

You feel her hands lift off from your shoulders. You don't pay much attention as you are busy focusing on your movements inside of Olivia. You begin to pick up your pace slightly, enjoying the freedom that comes from you being in full control. You push in deep, holding for a moment, savoring the feeling of her tightening around you, before slowly pulling back.

You once again feel a hand on your shoulder, this time it pushes into you, forcing you to lean over, laying fully on Olivia's back. You don't fight it as you quickly find this new angle works even better. You grab on to Olivia's shoulders, pulling her in closer allowing yourself to get in even deeper. You don't think much about what's going on behind you, that is until you feel something hard press itself in-between your ass cheeks.

"What's that!?" You ask in a surprised shout. You attempt to look back, but Erica's hand keeps enough weight on you to stop you.

"Joining in." She says as the pressing gets harder. Your entire body tenses as you feel the object forcing its way inside of you.

"Gah!" Is the only sound you can get out as more slides into you.

"Oh, quiet down." She says. You bite your lip hard as you feel yourself being stretched as she pushes even more into you. "This isn't even my big strap on."

You feel the pressure building as your ass continues to be filled. Just as you feel like you can't take anymore, you Erica's body is pressing against you, showing that she's gone as far in as possible. You remain still, attempting to not even breath out of fear of the dildo moving inside of you.

"As you were." Erica says as she gives your ass a smack. You can't hold back your gasp as your body shakes around the object, causing an intense sensation.

"Wh--at do you me--an?" You ask. You feel your body begin to tremble as your ass instinctively clenches down.

"Continue fucking Mistress Olivia." She says. You almost forgot you were even inside of her as your focus is on the thing inside of you. "Since this seems to be your first time being on the receiving end, I'll match your pace. That is unless, you're not capable of having that much freedom, I'd be more than willing to take control" You suddenly feel her pull back, sliding the toy out of you, only to instantly slam it back in, smacking her body against you once again.

"GAHHH!" You shout. You find it hard to even think straight as waves of pain and other intense feelings flood your body.

"I probably don't have to tell you that I like it rough." She says "So what'll it be? "
