We had my gf, Red's best friend, staying with us for winter break. She was 5'4" C boobs small waist huge ass. Was very innocent. That is. Until she went to college.
She had only recently discovered masturbation at 19 and was addicted. In fact when we picked her up at school we slept overnight in her dorm because we got there late and were at the parties going on at different locations celebrating the beginning of break. We had fun that night too lol.
We were on the bottom bunk bed under her. She woke me up shaking the bed finger fucking her self so hard. I could hear and smell her pussy. Side note: I have a super sensitive nose. It had a good pussy smell, not a bad pussy smell.
Anyway,
She was shaking the bed going at her self. I started stroking to it because she was going at it so hard and it turned me on plus, morning wood.
Red woke up and looked at me like "WTF are you doing" then realized I wasn't the instigator. She listened for a bit while stroking me then sucking my cock I came real quick in her mouth. She then jumped up and said "Good morning! OMG JEN what are YOOOOOUUUU doing? Dan stay down, Jens not decent"
That's how we got into a discussion and found out about her lack of experience in self gratification.
Anyway,
She had a bad back, so she slept in bed with us instead of the couch. We had slept in the same bed before, even all cuddled together. Which we were doing that night. We ended up sleeping with one of the girls on each side of me. She slept on my right, which was the side Red usually slept on. But, her friend Jen needed to use the restroom often, the girl had a pea for a bladder, and it was on that side of the bed.
Half way through the night, I started having a dream, IYKYK. I was jostled to J waking me up because I had pushed her panties aside and was rubbing her pussy and had been rubbing my cock against her ass. I was horrified and said "I was half awake thought you were Red." She said "I know it's ok." Luckily she was not upset and quite understanding.
We woke up Red and told her what happened. After she gets over the shock of what happened and was sure she really was ok. She laughed and said "Maybe we should get an air mattress. "
We got an air mattress the next day and set it up in the living room. Two nights after the fondling incident I silently walked to the kitchen past the living room at night to get a drink and she was finger fucking herself senseless watching porn on the TV.
