<human>: This morning it was a while i haven't seen my girlfriend so i went over to her house. When i got to her house i was surprised to see her 14 year old little sister in the house (apparently she had a no school). Her little sister was in her room upstairs playing on her iPad. Since it was 3 weeks i haven't seen my girlfriend, i wanted some action so we went to the basement to get a little action going on (keep in mind that door has no lock and you can see the whole basement from that door). 

We start making out, things get heated and she started undoing my pants and was giving me a small handjob. The moment she bent over to start giving me a blowjob her little sister opens the door and has a jaw dropping expression. My girlfriend was fast, pulled my underwear and pants up. It took my a second to realise what was happening, with my pants down, i rushed to the laptop nearby, pulled my pants up and pretended to fix the laptop. My girlfriend then went upstairs and asked her little sister what pizza she wanted.

I ordered pizza a few hours later with her little sister afterwards, she was never able to look me into the eyes, only looking downwards.

Give me a shortened version of the text
