Help with awkward sexual situations!!

I need serious help!!!! I was at my friend's house and we went in her hot tub, it was like two in the morning and her parents were already asleep. We were both wearing skimpy bikinis. She turned the jets on high, she she started rubbing my clit. She went harder and harder and I was really uncomfortable (we r both 13)...I squirt all over her. She told me to get out and I did, embarrassed. I sat on the deck and she arame over and took off my bikini top and started sucking my nipples! I didn't know what to do so I just sat there. She then slid her hand down my bikini bottoms and slipped four fingers into my vagina, and I orgasmed. We went inside and started making out, but we spooned and fell asleep. I'm straight and have a boyfriend but I really enjoyed it!!! What should I do in awkward situations like that, and I need DETAIL please!!!!!!!
