"Yeah Mom, we know!" Sue yelled back down the stairs, your dripping cock still buried in her twat. Still hard as iron and slowly growing another inch, you keep pounding into your sister. Her moans and groans grew louder and louder and it was no small wonder you didn't hear your mother coming until she was up the stairs and pushing on the door.
You saw it move and you almost jumped out of your skin, the movement making you pull out and step back from your sister, just over 10 inches cock glistened with Sue's juices and it was still bobbing as the door flew open.
"Okay, Sue, I..." your mom said and her jaw dropped. Apparently she wasn't expecting what was going on behind closed doors in her own home. Her eyes slid back from your cum-dripping, still-throbbing, still-hard, impossibly swelling cock to your sister's cum dripping box; a thick cream pie drooling from he still gaping gash.
Your sister turned around slowly, not fully knowing what to do and the three of you stood their in shock. |
