My friend's boyfriend caught me masturbating so he ate my pussy

so i was at my friend's house, and she was out running errands or something. and i was just hanging out in her living room, watching tv. and then i started to feel a little bored, and all of a sadden i was feeling a little horny. so, i went to the bathroom and i started to finger myself, and it was so good. and then, i heard the door open, and i was like, "oh no, who is that?" and it was my friend's boyfriend. and he was standing in the doorway, looking at me with this shocked expression on his face. and i was so embarrassed, and i just wanted to, like, die or something. but then, he started to walk towards me, and i was like, "oh no, what is he doing?" and then he was like, "don't stop" and he just got down on his knees and started to eat my pussy. and i was like, "oh my god, this is insane" but it was also so fucking good. i was so surprised, but also really into it. and he was really good at it. he's licking my pussy and my clit and i was like, "oh my god, this feels so good" while i was rubbing his hair. i told him don't stop and he smiled at me. and it was like, this huge relief. and he was like, "oh, you're so good" and he just kept going. and i was like, "oh my god, this is so wrong" but it was also, like, really right. because it felt so good, and i was so into it. and then i started to come. after that, we just stopped but then he just smiled, and he was like, "that was really hot" and i was like, "yeah, it was". after that i told him to go out of the bathroom and he did. after i cleaned myself, i went out and i didn't look at him and i didn't know that my friend already came back from outside. looks like she has no idea of what happened.
