Not really an exciting story, just something I felt the need to be able to say.
A friend of mine, Jacqui, who also happens to be best friends with my girlfriend has a very nice body. I do not know her sizes but she is pretty skinny and has very nice curves.
Anyway I have a very good sexual relationship with my girlfriend but a lot of times that we hang out, we are with Jacqui as well and sometimes I find myself staring at her body with my girlfriend right there.
She often wears shirts with low cut necks, and gives me a perfect view of her cleavage, and she sometimes wears kind of loose bras so I find myself seeing almost all of her breasts and I can't look away even with my girlfriend right next to me, and I start staring as long as I can to try to see her nipples, and I really think that she does it on purpose sometimes. Like today we were working on a puzzle and she was sitting across from me, and she kept standing up and leaning over to my side of the table to put pieces in, and when she was just looking she would rest her chest on the table and lean forward making her cleavage look amazing.
I often look at pictures of her while I masturbate, and even think about her while I am with my girlfriend.
