After wathcing porn, my friend stirs me up and penetrates me in the ass in doggy-style without taking off my pajamas

After any movie marathon with her and even after sleeping, she aroused my dorm buddy and he could not resist. He stripped me naked and got inside me impatiently from behind, and I just wanted to stay that way. That hot load on my ass was the last thing he needed to do to get me back for good.
