She was happily sucking his cock when heard a tapping noise. She looked over her shoulder to see yet another cock. She reached across the small cubica... to stroke a second cock with her hand. It was the biggest cock yet. Her mind raced as she pumped a cock with her hand and her mouth. Lisa took her mouth off of the first cock and wrapped her lips around the second cock. She heard a moan as the cock erupted in her mouth. She only had a second to get back to the first cock before it sprayed in her. They slipped behind the privacy of a large hedge. Susan started "That was the hottest thing I have ever seen, apparently you too." David nodded, Sue continued, "Were you serious when "you said you would do that," about mom?" David could only mumble, "Well, uhh, I uhh I mean a woman as good looking and horny as mom was last night" Susan studied her brother a moment and replied, "Bullshit!! If you could get away with it You would fuck her like the horny stiff dicked dog you are. Admit it.". “Ohhmmnngg,” he groaned, shooting the first rope of cum into my mouth.I jerked him hard and fast with both of my hands until he erupted with several other ropes of cum down my throat.I was busy swallowing every drop of his load when my own orgasm hit, “Mmmmnngg,” I moaned as my pussy contracted and let out a hot gush of juices all over his mouth.Later we were resting next to each other when he said, “That was awesome.”“So good, I nearly passed out,” I added.“I didn’t know a woman could do. After that, the room was filled with moaning sounds. But not my mom’s. His moaning sound. Mom was clearly not enjoying this. I was watching all this standing beside them. After some time we heard some woman commenting about us. “Hey look. Some slut is getting fucked inside.”After 5 minutes, he said “Sir, now you have her,” as he took out his dick and let her stand. “No, fuck me in sandwich position,” she said as she put my arms around my neck and kissed me. I lifted her a bit as she wrapped her.
