Deku: You both were completely nervous. Deku suggested having all the lights turned off and you suggested to do it underneath all the blankets. You've only ever seen him shirtless one time during training when the top half of his costume burned off and he's never seen you in anything less than when you wore a tank top with shorts. His hands shook when he went to touch underneath your shirt since you felt self conscious about taking it off, same with your underwear. You were scared to touch his bare skin but he said it was okay. Deku was afraid to make you more nervous so he took things slow and with every move he made, he asked if you were okay and if you wanted him to stop. He was really sweet to you the entire time.

Bakugou: It was your first time, but not his. You were afraid that he'd get annoyed with your lack of experience but it was the exact opposite. He found it flattering that he would be your first. He took his own shirt off first then slowly began to undress you while he kissed you gently on your lips and down your neck. He noticed how hard you were blushing and asked if you'd rather wait until another time. When you refused he smirked and continued. He made sure to prep you and do some foreplay first so that he wouldn't hurt you too much when it came down to doing business. He was more caring and gentle during this intimate moment. Although you could tell by the look in his eyes that he wanted to go wild, but he'd only do that if you asked him to.

Kirishima: He respected your boundaries and would feel guilty if he was the one to suggest having sex, so it was up to you to bring it up. When you finally did, he panicked because he didn't have protection, but you came well prepared. Kirishima was way more nervous than you were so he let you take the lead. When he gained the courage to touch you he kept asking if it was okay to touch you here or there. Harder or softer. He wanted you to want everything he was doing to you and not regret a single thing. You both had a really nice time.

Kaminari: You both couldn't help but to crack jokes the entire time to mask the awkwardness in the room. You kept giggling because whenever he tried caressing you, it tickled and you joked about having a foot fetish and dove for his feet. When you tried tickling his feet he flailed around and you threw yourself off the bad acting like he kicked you in the face. It was mostly making out that you two did but when he finally got between your legs and heard you moan, it sounded so sweet in his ears. You held him close when the pain began to evolve into pleasure and he whispered in your ear, "Are you feeling it now, Mr.Krabs?" You both snorted and just let things flow. All in all, the first time was way more fun and not as weird as you both thought it would be.

Iida: For someone who was not experienced, he sure knew what he was doing by the way he made your body feel. You made it known that you had been wanting to get more intimate for a few weeks now, so he read up on how to stimulate a woman's body. He wanted to be prepared for when the time came. And oh my god, he was more prepared than ever. He even had a few toys to experiment with if you were down for it. You quickly refused but kept an open mind. He apologized quickly and told you that the article he read said it would be a good idea and that he wasn't trying to be creepy by suggesting to use these sex toys. You couldn't help but laugh. He always took things too seriously.

Todoroki: Could have been better but it was definitely memorable. You both kept accidentally hurting each other and trying to find a comfortable position. He was trying some weird stuff and claimed that it worked in the video he watched the other night. "Maybe this isn't working because the man in the video had 2 women with him. Do you want to add another person to see if that makes a difference?" He was very dense indeed. But soon enough you both found what worked for you. Only thing is, he forgot to lock his door. "Shouto, do you know where I put my- *turns on light* Oh my god, son! I'm sorry! I didn't know you had company in here!" Yeah, Endeavor walked in. Maybe you'll try this again in the dorms next time.

Jirou: She was shy at first but opened up more when things got moving. After a hot make out session she ripped your shirt off, literally, along with her own. She couldn't help but straddle your waist and kiss down your neck and pull at your belt buckle, motioning that she wanted more. You didn't know if she watched too much porn or if she's done this before. But you remembered that she swore that she was a virgin. Jirou was just a natural.

Ochako: Literally wanted to have sex with all of her clothes on. After things started getting more steamy, she started to slowly peel away her clothing but refused to take off her bra and underwear, which was okay with you. You had to be very gentle since almost every movement you made hurt her and the last thing you wanted to do was cause her pain even though the first time will be semi painful. At one point she accidentally made you float when she got too into things and unknowingly activated her quirk.

Momo: You weren't even aware that sex was something on her mind until she asked you to come to her dorm because she wanted to have a talk. That's when you found her sitting on her bed in nothing but a robe. When you asked what she wanted to talk about, that's when she took it off and told you to join her. Momo kissed you softly and gently took your hand and placed it on her boobs, motioning that it was okay for you to touch her. She made all the moves which told you that she had been wanting this for a while.

Mina: Absolute freak! She really wanted to show off her flexibility to you which was honestly super hot. You were afraid for your life though when she started to get wild. She had so many things she wanted to try, including using toys and experimenting with kinks like chocking and bondage. You had to be the one to tell her to chill out.

(First Time with each other. More explicit and smutty since they're adults)

Hawks: You bought yourself some sexy lingerie when you decided it was time to give yourself fully to your boyfriend, and on his birthday nonetheless. He couldn't wait to finally see what you were hiding underneath your clothes. He quickly stripped you down and stared at you in awe. He wanted to worship your body for a moment. His eyes couldn't peel away from you, going from your feet all the way up to your toned stomach and to your amazing sized chest and then to your beautiful face. He then pulled out his phone, "mind if we do a photo shoot before we get started? Y'know, to get me through the nights when we're not together." Hawks was the best lay you've ever had. He really knew how to make a woman feel good and made every movement count, from his hands pinching your nipples softly to rubbing your clit in steady circular motions. His dirty talk alone was enough to get you soaked. Hawks decided that he wanted to remember every second of this moment so he propped his phone up and got a perfect angle of the bed to record the two of you.

Endeavor: WOW he was so strong. He tossed you over his shoulder like a rag doll and planted you on his massive bed. With a swift tug, your dress was in pieces as he tossed it to the side. If you had boughten it you would have been mad that he ruined your dress, but since he got it for you it didn't matter. Sugar Daddy Enji would just buy you another one. He avoided topping you considering how much smaller you were compared to him. So he let you be on top, and even then you weren't in control. He positioned you carefully on him and moved your body and hips in the best ways so that he was the one putting in the work and you got to enjoy the ride so to speak.

Shigaraki: He was more interested in sexting than having actual sex. Sex meant putting in a lot of effort and he wasn't about that life. If you wanted him, then he let you know that you'd be the one doing all the work and that he'd follow your lead. Which was honestly okay with you. Shigaraki deprived you of sex so there was a lot of things you wanted to do to him.

Toga: Freaky freaky freaky! She would always send you raunchy/sexy photos of herself to tease you. Toga knew you weren't ready to be with a girl like her, so she slowly lured you in and prepared you for what was to come. When you would make out, she'd cuff you and kiss you wherever skin was visible. Sometimes she'd put a blindfold on you and strip down, then give you a lap dance. Then when you were ready she let you do whatever you wanted to her no matter how freaky it was. She already had costumes if you ever wanted to role play, toys to use on each other, and she one time brought "Father" into the room if you wanted to use it on her. You freaked out and told her to put that thing back where she found it before Shigaraki turned you both into dust.

Twice: He wanted to pleasure you so badly and go crazy. You told him that you could handle whatever he threw at you. Oh did that make him happy. You and Twice both fantasized about having an orgy. So he made clones of you both, along with some other people you both wanted that he had data on. It was a wild night that ended very messy with cigarette smoke in the air when you were both finished.

Dabi: Oh how he's waited for this night. You knew he was a sadist. So when you were ready to have sex with him, he lost all control. Rope to bind your wrists and ankles, a gag, vibrators. He wanted you to beg for his cock before he gave it to you. Dabi wanted to watch you tremble and for your body to ache for an orgasm. He teased your body until it was at its limit and then finally gave you what he wanted. He left scratches, bruises, and small burns on your body. You never knew how much pain could turn you on. Of course, you did have a safe word in case he got too rough with you. It didn't get to that point in using it though. Dabi knew how much you could handle, and read your body language and stopped whatever he was doing if he could tell you didn't like it.

Overhaul: Shower sex. You weren't surprised that this is what he wanted. What would you expect from a guy who's obsessed with cleanliness. Your clean skin and hair, along with your flowery scent turned him on big time. He couldn't keep his hands off of you, which was nice because he always held your hand with his gloves on. His mouth felt so nice against your neck and lips. Overhaul's lack of affection made you want him even more. You needed him to touch you on the spots that made you feel good. He ran his tongue over the front part of your body, loving the way you tasted and felt. His hands roamed all over your body and fucked you with his fingers while you begged for him to give you more. He turned you around, pressing you against the wall of the shower and fucked you from behind while whispering profanities in your ear. For being so clean, he sure knew how to get dirty.
