Her sister seduces me with big breasts and creampie OK

My girlfriend will never let me do it raw! Just as she was about to insert it in a condom clothes, her lady burst into her room! After getting in the way and having had an incomplete burn, I was in the bath alone, and as an apology, my sister seduced me by allowing me to be raw and creampied! I love her, but if I were seduced by such a busty, lewd woman, there's no way I could refuse! I'm at the peak of excitement at the thrill that you might find in my girlfriend and the pleasure of creampie sex that I can't normally get... At the end, I'm cumming inside her in front of her!
