Fuck Monica's pussy

"Oh good God, Ross," Monica pants in the wake of her orgasm. "Why did Rachel ever dump you?" She smiles down at me, kneeling between her white thighs. I smile back at her as I stand, and gently rub the head of my rehardened cock against her wet, sticky lips.

"Ross...no..." Monica says, though there's a teasing tone to her voice. Plus, the wide smile on her lips is proof enough for me that she wants me to fuck her.

"Yes..." I tease back, and slide the head of my cock into her. I never would have thought that my little sister's pussy could be so tight; considering how many guys she's slept with since she got thin. We both moan in ecstacy as I slide further into Monica's cunt.

"Oh God, Ross," Monica moans, I can feel her pussy squeeze my shaft as I go deeper. "You're so fucking big!!" I bottom out inside of her, and we both moan loudly, and then I start thrusting in earnest. Hard and fast I pump into my little sister's tight, dark-haired pussy while she writhes and moans beneath me.

I pound away, meeting Monica's obscenities with my own as we fuck like animals. Finally, I feel that familiar tingling in my balls. "I gonna' cum, Mon," I gasp. "I gonna' cum!"
