Dawn's (my wife) sister lived with us for a while before we married, and she used to watch us have sex fairly often (we hardly ever closed the bedroom door ). Her sister gave me head a couple of times (at Dawn's urging) while I fingered her. We showered together probably 15-20 times, although nothing happened. We were usually in a hurry to go somewhere and only showered together so we wouldn't run out of hot water. I never got to go down on her and we never had intercourse. I did kiss her by mistake once. When Dawn and I first started dating, I went to pick her up and her sister answered the door. It was dark, and I thought it was Dawn (at the time, they looked almost like twins), and just stepped in and kissed her, and she sure as hell kissed back. I thought something was amiss because her tongue felt like a cat's tongue (no, I haven't been kissing cats ). When I stepped back and saw it was her, I said, "I'm sorry." She said, "I'm not." What can I say, Dawn comes from a strange family.
