Making my daughter prove she's not a lesbian.

My 14 yo daughter is "absolutely sure" she's a lesbian, Daddy makes her prove it, rather forcefully.

My name is Tom. My wife died 10 years ago, my daughter Mandy was 4, this was and still is hard on is both.

Mandy always had the "Tom Boy" phase, always wanting to dress like a boy, but not wanting to be a boy. I thought it was because she was chubby, like baby fat chubby not like obese. She's not a dress or leggings girl, but jeans and oversized hoodies, her haircut is a shorter cut, looking rather "dykeish". Our relationship was good, we had "Daddy - Daughter" days all the time. When she was 10, she got part of the "birds and bees" talk, about what she will be going through, but nothing sexual or masturbation related. She was literally grossed out when she realized she would bleed several days every month for the next 40 years. I made sure she had a "emergency period kit" in her backpack just in case. Trying to ensure my promise to my wife about taking care of Mandy. When she was 12, we had the sexual/masturbation talk, ensuring she was fully aware of what and how, she seemed grossed out once again, especially when I talked about what the penis is and does.

Her "emergency period kit" was now stocked with a couple condoms and lube packets, just in case, I told her I would prefer she didn't, but if she did, to make sure she was safe. She never seemed interested in boys, and had no guy friends, but multiple female best friends, sleepovers were common place.

One day, she came to me saying her laptop wasn't working, so I looked at it. It was the power cord, when it booted up, there was a password, which I figured out, I was curious about what she was doing online.

I was literally floored, she had multiple bookmarks for girl on girl porn, sites on lesbian culture, and more. I put it off as a "phase". I never told her what I found, didn't want to embarrass her.

She forgot her phone one day, I put her pin number in, and I was absolutely shocked, there's multiple pics and videos of her naked and masturbating, what was worse was seeing messages and what her friends were sending her.
It was a combination of furious and arousing both. When she got home, I told her about what I found, she said "you can't do that, it's my phone" I said "I can do what the fuck ever I want, because you're 14". I flat out questioned her if she was having girl on girl sex, she replied, "yes I'm a lesbian, I love girls", I yelled "you're 14, you don't know what the fuck you like, you think ranch fucking dressing is a food group", she stormed off to her room.

Thinking about what I read and saw, it really made a lot of sense, she was like 9 when she needed a training bra, she absolutely wanted nothing to do with it, her haircut, her more "butch" haircut, everything fell into place. I knew I was overreacting over this, and if that's what she wants, then so be it.

There was a definite tension in the house the next few weeks. I got home from a meeting with a FWB, and was still horny, I came to the conclusion if Mandy was a lesbian, then she can prove it to me.

I walked into her room, she quickly stopped what she was doing under the covers, I could smell the sex, made me rock hard. "What the hell dad?" I said, "you think you're a lesbian, then prove it"

"What?" She replied, I yanked the covers off her bed, exposing her chubby body, tits that were literally too small for her large frame, panties down by her ankles, her bald pussy on display. "Dad get the fuck out of here!" I smacked her across the face, she started screaming and crying.

"You've never had a cock, but you hate them?" She realized what was going to happen, she's begging, "please daddy don't, no daddy"

I pulled my cock out, 8" and decent girth, she looked at it. Then started screaming. I grabbed her by the hair, shoved my cock in her mouth, pushing and pulling her head, after a minute or two, knowing she wasn't going to suck my cock. I decided I wanted to suck on her puffy nipples, she was trying to pull my head away, with no luck. I held her down while I went for her pussy, she was wet, and tasted amazing, she's screaming and begging, but also moaning, I ate her through multiple orgasms. I stroked my cock, she realized she was going to get fucked.

"No daddy, please no, I won't be a lesbian, just please don't!". I rubbed my cock on her clit, I started penetrating her virgin pussy, felt resistance then through her cherry. She was screaming in pain and pleasure, I was able to get about half way in her, I was bottoming out, hitting her cervix, the sex was slowly in and out of her fat little pussy, I wanted to absolutely destroy her, but didn't want to traumaize her more than I did.

I was getting close to cum. "Daddy is ready to cum!". "OMG DADDY NO, DON'T CUM IN ME!"
I felt my cock unloading deep in her pussy, she crying "Daddy you're going to get me pregnant!"
"I don't care, and see you do love cock!
"Daddy I don't", "well your pussy says you do"

The next couple days were awkward, but I woke up to her sucking my cock in the middle of the night, so apparently she's bisexual.
