This is a story about how I lost my verity to my gf little sister.
It all starts one day I went to me gf house to see her I walk in and her younger sister was sitting at the table eating, in a shirt 3 sizes to big. I could see her pink panties with her sitting there. Then Jen came down stairs.
Jen: hey hunny.
Dave: hi babe.
I hugged her and kissed her once then again then we started to make out when her mom stopped us.
Jen: sorry mom.
Her mom: its ok.
We then walked out the door and when to school. Then next day when I came over jess was wearing the same thing but blue panties instead of pink.
Dave: is jen here?
Jess: shell be right down its Friday she always takes long on Friday.
Dave: ok.
Jen: babe are you here?
Dave: yes.
Jen: come up here.
I walked up the satires and went to her room and saw she was in her bra and jeans she grabbed me and stared to kiss me I felt her Tung on my lips so I let it in my mouth we sat like that for a good 2 minuets before her mom walked by and knocked on the door.
Her mom: jen dear where’s you bf?
Jen: umm he must be late.
Her mom: can I come in?
Jen: no im not dressed.
