Niece grinded on me
So this weekend my 18f niece came over to use my pool since it was finally warm enough and I decided to join her. She came out in a lovely purple bikini and splashed in. After about 20 minutes of floating and soaking around she came over and bumped into me with her cute bubble butt. First I thought it was an accident then she kept backing up her bubble butt against my dick in my trunks. I didn't stop her and just let her rub and then grind on my hard cock while I enjoyed it. After a good 5 minutes I reached forward and slowly started rubbing her pussy through her bikini bottoms, making her her grind faster and harder. Another 5 minutes of this later she let out a little moan and shiver from a small climax. Unfortunately before I could get off she walked out of the pool, needless to say I felt incredibly blue balled lol
