My stepmom was having a threesome but found out it was a foursome. My stepmom told me a few of her threesome stories.. some of them included my dad. (inset me gagging). One time during her younger, wilder, MORE drug fueled days, this kinky couple she knew asked her to have a threesome with them and even wanted to through in some cash. My stepmom being the hustler she is accepted event though she would've been interested without the bribe. So anyhow they all started going at it, my stepmom, this guy, and his girlfriend. My stepmom said she actually enjoyed it since she identified as bisexual. She had relations with girls but mostly ever had boyfriends. She said the guy was ok but his girlfriend was really pretty and had a beautiful body but..yup... in the middle of everything, she noticed a small but clearly defined bulge on this other woman's lower abdomen. Yes, she was a few months pregnant. My stepmom was understandably turned off by the fact that the threesome had sorta in a way turned into a foursome... yikes!!
