I felt like jerking off looking at my girlfriend's friend

I was in the bathroom when my girlfriend's hot friend came in with that lingerie up her ass, which of course left my dick throbbing. At the same time I started playing one looking at her and the naughty girl couldn't resist seeing my dick throbbing with lust in front of her. She fell in my mouth very tasty right there in the bathroom and asked me to eat her heartily until her pussy was all swollen...
