Sucking cock alongside my bff got me horny, so I climbed on that cock without asking permission

I was with my bff Diana sucking on our friend William's cock, but only sucking doesn't satisfy me, I got horny so I had to fuck that cock!! Without asking for permission, I took off my panties and climbed on his cock to fuck my pussy with it!! It felt sooo good! and Diana came back afterwards for the cumshot! So it was really hot!
