Fucking my lover and her perverted virgin brother bred me (19f)

I was seeing a girl that lives around my school, she attended university but lived at home with her mother, father, and brother. We had originally matched on tinder and hit it off, and I don't date but would semi-frequently hang out with her to get some female attention. This particular string of events happened during the summer, leading into fall.

She invited me to her house during a time where her brother would be at school, her parents at work while we didn't have class, and I didn't have practice . We often sunbathed outside as she got extremely horny for tanlines so we went out on her family's pool deck in our small bikinis. Her pert breasts jutted from her chest without the confines of a bra and her toned ass was covered slightly by the thing she was wearing. She put her brunette hair in a ponytail so she wouldn't get suntan lotion on her hair or get odd tanlines from it.

I was in a similar outfit, my bikini covered only my nipples, and if I shifted the wrong way my entire pussy was free for the world to see. It's how she liked me because she was freakier than me.

While we talked and tanned she brought something up to me, "I think my brother had been listening to us have sex, he might have even been watching." she said.

"What now?" I blinked, looking over at her.

"You already know I've caught him sniffing my panties and moving my underwear from my laundry, But last time you were here I saw the door creak open." she explained.

Her brother had a long history of perversion, he often looked us up and down when we would wear skimpy outfits around the house. Before I met my lover, she caught him watching her masturbate, and sometimes suspected he came in her panties but never caught him. We thought he was a virgin but she didn't know for sure. She had told me his dick was relatively small though, from what she could tell.

"He's constantly staring at you when you're here, Eva. Honestly it kind of turns me on, thinking my brother has the hots for my ‘friend'" she continued.

I grinned, she was such a kinky girl, anything that would turn me on turned her on. I reached over to gently play with her glistening thigh, "You think that's hot baby? Don't start something you can't finish."

"Mmmm do you have a plan?" she asked, goosebumps forming on her leg where I was touching.

"For him? Nope. For you, yes." I said, crawling onto her seat, she spread her legs for me without hesitation.

"Yes, mommy." she replied, and my bikini bottoms literally nearly flooded at that, she knew her saying that would turn me on.

I reached down and undid her bikini bottoms while she pulled aside her top to the sides of breasts, exposing her tan lines and sensitive bits. Her hands were on her breasts, then nipples which illicited a moan from her. My hand went to her pussy, gauging her wetness, my fingers dropped with her fluids which I put in my mouth. Dramatically sucking my fingers for her benefit only proved to up her urgency, she begged her mommy to eat her.

I leaned my head down between her legs and used my tongue to gently lick up and down her slit to tease her. Her hips thrust back and forth in desperation as she let out gasps from her own attentions on her nipples.

"Please. P-please I need it." she begged.

Conceding to my own desires I slapped her pussy once as punishment for not begging more and then wrapped my lips around her clit. She whined under me as I provided suction onto the sensitive nub. My tongue moved back and forth on its very end and she began gyrating her hips to induce further pleasure.

"I love when you suck my clit mom— WHAT THE FUCK!?" she cried out, trying to suddenly cover herself.

My ass was up in the air as I was effectively in doggy position trying to eat her out, so I was entirely exposed to whatever she was staring at toward the door. My pussy obscenely splayed against the fabric of my bikini and it was clearly wet, and not from swimming. My nipples were still covered as well but protruded prominently as I sat up and looked toward the door where she was looking.

Her brother stood there, scrambling to get his pants up as his hard cock swung wildly around. I narrowed my gaze, before getting up.

"What're you-" she started before I held up a finger to shush her, I saw opportunity.

I marched to the door, swinging it open before her brother could run away, "Come here dickhead."

I dragged him by his collar to where we were, his sister was struggling to put on her bikini bottoms, I made him kneel in front of me.

"Were you watching us fuck, you pervert?" I commanded an answer.

"Y-yes." he said, looking down.

"I'm assuming this isn't the first time, am I correct?" I asked.

"Yes, I watched you guys before." he responded.

"I see. Well, are you a virgin?" I said.

"I am, one girl kissed me before." he winced, like it hurt him.

"If you eat my pussy well enough, you might just find yourself not a virgin." I said, pulling down my bikini bottoms and revealing my clean shaven cunt.

He marveled at it, and I moved back to my doggy position on my lover's chair. I waggled my ass and he moved over to me, placing his tongue on my pussy. He wasn't good, I'll say that. I began eating my partner, who was very turned on but had to stop frequently to instruct the boy on how to properly please me.

The sun pounded down on the three of us as eventually we found our rhythm and my moans illicited moans from my lover and her moans made her brother have more fire in his licking. My lover came on my face, and I shuddered, having a small orgasm myself.

I rearranged myself so I was on my back, my lover on the other chair facing me and her brother was standing over me.

"I like being dominated by men, understand?" I asked.

He nodded nervously as I pulled down his pants to reveal a very average cock in both length and size. It would do.

I guided him to my very wet pussy, and instructed him to push forward. I moaned as he entered me and he groaned.

"Congratulations, you're free of your virginity." I smirked.

He began to thrust in and out of me rapidly and my eyes rolled back.

"Fuck me baby, fuck me in front of your sister." I cried, the neighbors were definitely going to have questions.

He was relentless and had surprising stamina for a virgin, I later found out he had already came before we caught him.

My legs bounced around as my heart pounded from the intense taboo that was occurring. Aside of me I heard slipping sounds of my lover pounding her own pussy with her fingers, moaning obscenely and egging him on.

"I love it, choke me." I whined, and choke me he did.

His dominant male instincts turned on and I couldn't breathe as he fucked me harder and harder. My pussy made wet sounds as he slid in and out of me over and over again. He growled with aggression as my blonde hair was ripped from its braid. I got flipped onto my stomach and he pulled at the back of my hair.

"I want to cum in you while I stare at the ass that's teased me." He growled.

"Yes daddy, my pussy is yours." I whimpered.

He fucked my little pussy doggystyle and I submitted like a good slut while my lover watched her virgin brother take me. She was so into it, she came twice in the first five minutes. Sweat and pussy juice flew off my ass as he fucked me, and eventually he told me he was going to cum.

I wiggle my ass and after a few thrusts be bore himself as deep as his little cock would go. I felt the warmth shoot into my pussy and I cried out in an orgasm, my lovers little brother was fucking breeding me. I shook and moaned, my eyes rolled to the back of my head as spurt after spurt of semen filled my fertile hole. I collapsed onto the seat and her brother fell back into the patio. I gestured for my lover to come clean me.

Her pussy was right in her brother's face as she crawled to me and ate the leaking cum from my pussy. I panted and came again at the taboo. I couldn't fucking breathe it was so fucking hot. We all lay there until around five, when her parents came home. Her brother hid in his room while she and I had another session of quiet sex fantasizing about her brother dominating her…
