IENE-637 Out of pity for miserable me, my best friend's girlfriend agreed to let me 'grind' against her and do some dry humping. But we both got too into it, and her pussy was soaking wet! So I just slid right in! "What?! It's inside?" But I couldn't stop

I was told that the girl friend I had been secretly in love with started dating my best friend, and it made me feel miserable. The two of them, not caring about me at all, only made my misery worse... In this situation, when my best friend went out, leaving just the two of us alone, I was overcome by a moment of madness and tried to play a trick on her but failed. The atmosphere became awkward, and I thought it was all over, but then she said, "I can't go any further because I'm your friend's girlfriend, but if it's just about dressing up, that's fine."
