By the way, Tom, remember what you said about your one time with Sharon at the lake cabin? You said she seemed to be getting aroused humping your leg. You see, Tom, she was stimulating her clitoris by rubbing it against your leg. Among bisexual women and lesbians, that behavior is called tribadism or tribbing. It just means rubbing. It is a behavior that allows women to bring each other to orgasm without any vaginal penetration. Men rarely understand that it can be a technique a woman can use with a man to speed up her own orgasm so it more closely coincides with his.
Based on what you said, I'm sure Sharon was close to cumming. You said you pushed her back toward the couch, but I'm quite certain she was pulling as much as you were pushing. With her own sexual experience as a married woman, she knew you and she both were close to cumming. She was trying very hard to get your cock inside her so you and she could cum together. Unfortunately, her family returned, and that left you both sexually frustrated.
