Sister From My Gf.

I was overnight at my gf place were in a relationship for 1 month.
I dont love her i was always for the last 2 years now focused on her yn sister.
Most times i take the sis socks or pantys with me.

Yesterday my gf were drunk i told her to drink it will be funny in the end she puked and went to sleep.
her mum was at work and i dont know i was drunk and couldnt resist anymore and went down to the basement where she has her room.

I noticed she already was in bed and watching tik tok or anything

So was going around to look in her room all the time when she suddenly came out and asked me what im doing

I told her i search the restroom im drunk. she just pointed to the restroom down the hall.

i tried to talk to her bout schol, if she have an bf or ever had one and she was not interested in me not at all

i didnt plan to do anything on purpose but i took her head, held it and pulled it to me and tried to put my tongue in her mouth.
for like 3 seconds my tongue were inside till she realized and snapped and tried to pull away.
I followd her in the room close the door and went on the floor with her

After like 20 min of me on her just making out even though she didnt want to but didnt really resist. proply shock

took her clothes off and made her watch into my camera of my phone and made multiple photos and videos

Then i told her if she turn around and let me grind against her butt for a minute i would stop.
So she did or i just turned her around she didnt rlly did herself.

I pulled it out and grinded against her butt in pantys.
I came and rested on her for like 2 minutes.

When i were done i told her to never tell it anybody and if she liked it she can have it again and that im sorry shes just to hot to resist.


she nodded yes and layd there till i was gone
Then i went to my gf and went to sleep.

The next day she didnt said morning nothing she just stared in a direction and didnt talk at all



i feel guilty im a bad person it was proply the best orgasm ever but it was wrong.
Still i wished to went for it completly in her like real sex.
Because i already did the worst thing i forced somebody for that
So why not does it make a difference?
