My girlfriend and I masturbated watching her friend's nudes. [FM] | 2016

EDIT: [F20][M20]

Yesterday, I was cuddling with my girlfriend on the couch and she started watching the photos on her phone. We started to discuss the outfits she was wearing and then her friend's ones.

Then she began to tell me that her friend Norma had an amazing body; to which I responded that she didn't (because I didn't want to get myself into trouble). So she showed me more and more photos telling me things like:

– "Look, her boobs look amazing, they are the perfect size"; or "Check her ass, is super round"; at first she was genuinely trying to convince me that Norma had an amazing body (and she does, but I couldn't risk it).

The problem is that I started to have an erection and, of course, to think less clearly; so I replied more and more directly, like:

– "Well, yes; her ass looks great, but maybe because of the pants; let me see her with other pants.", and "If you had a picture of her in a bikini, I could make a better judgment".

We began to get more and more aroused and our conversation continued getting weirder and weirder... until the point where she started to tell me things like:

– "If you saw Norma naked, you would love her; her nipples are small and pink; exactly how you like them" and "She uses sexy lingerie almost all the time, when we are trying dresses together, sometimes I can see her vagina through her panties".

At that moment, my penis was totally erect and I was rubbing her vagina with my fingers, all over her pants.

Then she entered FB and started typing Norma's email and password; to my surprise, she logged into her account and immediately click on her messages with her boyfriend.

All the images that she shared over FB were shown in a grid; there were a lot of regular pics but also nude pics. She opened and we started to discuss her body with no restrains; saying things like:

– (Me) "You are right, her nipples are amazing; I would definitely suck them" – (Her) "His ass is so big that your penis would be completely hidden in there"

She pulled my penis out of my pants and I unzip hers; so we started to masturbate watching her friends nude pics and imagining how it would be for me to have sex with her.

After five minutes and about 10 nudes; a photo of her having sex with her boyfriend appeared and my girlfriend started to moan louder, so a I kept touching her until she had an orgasm. She stroked my penis harder and I came at the same time.

We haven't talked much about it since; but a few days after I told her that it has been crazy but amazing and she said that indeed that was great.
