I fuck my friend doggy style, without taking off my red panties, cum right on her back!

I saw my girlfriend caressing herself on the bed, imperceptibly approached and began to help her. The girl did not mind and turned her back to me, I was in my army T-shirt and immediately planted my powerful penis in her balls! She moaned sweetly and I began rhythmic movements that made her moan even louder! I fucked her from behind and cum unexpectedly, but managed to pull out my unit and pour sperm all over my girlfriend's back and ass! She was shaking in the convulsions of orgasm and I was also growling with pleasure! We loved it so much that we decided to continue next time!
