My girlfriend Liz just found out she was pregnant. She wasn't showing at all, but she was very excited. Liz called her sister Betsy and gave her the news. Betsy decided to pay a visit and see her now pregnant sister. Betsy was unlike her older sister. She was blonde with fairly large breasts. Liz was dark haired and on the slim, petite side. The night that Betsy arrived, we broke out a bottle of wine or two. Before long, both women were fairly tipsy. After we got caught up on all the events going on in our lives, it was nearly midnight. Liz and I decided to call it a day.
My girlfriend gets very horny after drinking a little alcohol. We got into bed and in a few minutes I was fucking Liz. I had her legs up over my shoulders and I was slamming her pussy with my meat. My cock was hard as a rock and all I wanted to do was drive my pecker into Liz. I'm afraid my girlfriend gets pretty vocal in bed. You could hear skin hitting skin as I slid my cock in past Liz's wet folds. She had my cock in a death grip and I was finding it hard to control myself from cumming.
I fucked her pussy faster, knowing I was almost there. Liz started to convulse and I lost it. I blew my scalding load of cum deep into her belly. I just kept pounding her until I got soft and slipped out. I stood up and looked down at my girlfriend. She was lying there on her back, her thighs were spread and her pussy was leaking from all the seed I shot into her. Just that moment I heard something stirring behind me. I turned around and there was Betsy, she was standing in the doorway.
"I heard you both and I couldn't stand it any longer," she said.
Betsy had her bathrobe on. She walked into our bedroom and slipped it off. Betsy then got up onto the bed. Liz was watching her the whole time. I was standing there paralyzed. Betsy crawled in between her sister's thighs and began to lick her cum stained pussy. Liz reached out and took hold of her sister's head. She had her fingers in Betsy's hair, urging her on. Both sisters then proceeded to have hot oral sex on our bed!
