hello guys!

my first ballbusting experience was about 2 years ago. at this time I didn't know about this fetish.
I was lying in the bed, next to my girlfriend. she was kinda horny this morning and i wanted to serve her. as i started to stimulate her, she put her left leg between my legs ( i was above her) and startet to pull her knee up gently into my testicles.
although it hurted i enjoyed it. as she was enjoying my handwork more and more her knee bekame faster und she hit me stronger. it seemed to give her an extra kick and she reached her climax quite fast. i was a little but moaning in pain and pleasure at the same time.
it was great. not a hardcore ballbusting but enough for me
