My Junior year of college I had a girlfriend who was very uninhibited about sex. She knew what she liked and was very direct about it from our first hookup. She was constantly showing me new ways to make her cum, new positions etc. It was a stupid college relationship but the sex was great.
As is the case at most schools, she had a roommate. As is not often the case, her roommate was Mormon and completely uninformed about sex. We always tried to be very respectful and wait until she was gone to have sex, but one night we just got so horny that I couldn’t help but finger her just the way she liked while we were spooning and her roommate was asleep. She was great at holding in her moan, but unfortunately I wasn’t when she returned the favor with a BJ under the covers. My “oh fuck” woke up her roommate who promptly asked what we were doing.
My girlfriend, never the shy one, told her that I had just made her cum and she was trying to do the same for me. The roommate had so many genuine questions that it turned into an advanced level class on male anatomy and blowjob technique. It was honestly one of my weirder experiences but so, so fun and satisfying.
