It was my girlfriend's 18th birthday, and she was horny. It didn't take a genius to tell, especially the way she bit her lip as her hand was slowly rubbing up and down her crotch through her pants. We were in her room with the door closed,nobody home. Seeing her so turned on always turned me on as well...

I scootched over to her closer super quietly and slowly put my hand on top of her rubbing one. She was so focused on the chick on t.v with amazing cleavage that she didn't notice until I started rubbing with her.

Her porcelain cheeks turned bright red and she looked at me saying "Whoops..." She had been playing with herself for a good 10 minutes but she was totally sidetracked the whole time.

I got real close in her ear and whispered "whatcha doing there?" She simply moaned. I smirked and got on top of her, and she willingly helped me pull off her shirt. My girl's tits are so fucking amazing. I lowered my head and started sucking on her glorious nipples like a baby. She grabbed me tightly and obviously wanted to get straight to pussy action.

Action led to action, and we were suddenly naked on her bed, with me eating her out for a nice birthday gift. Her pussy was better than any birthday cake that could ever be made. I fingered her, ate her out, and more and she returned the gift. She was fingering me and I was moaning really loud, I figured nobody was still home.

But.. her smoking hot stepdad came home a few minutes before. He heard my moaning and ran upstairs, and blasted the door open, to reveal his daughter fingering a girl. He yelled at us. Our relationship had been a secret even though now we were both adults.

He told us we'd have to be punished for keeping this a secret, I didn't really know what he had in mind...He strengthfully pulled my naked body out of her dripping wet finger and left me laying on the bed with my legs wide open. Not gonna lie.. I was kinda turned on.

He knew about my girlfriend's tits,and how nice and big they were. He smirked and pulled off shirt, and obvious boner coming through his jeans, he unbuttoned them for relief. He was massaging her tits and licking them, after each lick, kissing her. We were both bisexual, and had talked about how hot her stepdad was, so this was actually a fantasy come true. He eagerly pulled down his pants and boxers, put his extremely erect dick in between her tits and titty-fucked her, each time the huge dick came up, she gave it a little suck.

I kneeled up behind him and rubbed my tits on his back. "Mmm...just like that girls..Don't tell mom" I began to kiss his neck and he turned around to me, and stood up on the bead so I could suck his cock. I haven't given too much head to guys, but that was the best tasting cock i'd ever had. He moaned and then came back down and rubbed his stepdaughter's pussy, then spitting in it.

"You ready for your punishment, fucking slut?" She licked her lips and nodded. He slipped it in and had no hesitation to thrust, hard. He was really in there, i got on top of her face so she could eat me out.

I was getting eaten out and having a make out session with him. She was getting fucked, eating pussy, and her tits massaged by her stepdad. He was fucking her, kissing me, and massaging her tits. We were all moaning. I felt the vibration of her moans in my pussy and he felt the vibration of moans in his mouth.

He pulled out and he asked "who wants to suck the cum out?" I practically jumped over my girlfriend and i gave him amazing head, with so many teases. My girlfriend laid down, with her ass up, and started eating out my ass. I swallowed all his delicious cum and restarted his libido by slipping himself into my tight pussy. He groaned fucked me so fucking hard. My girlfriend was hardcore making out with me with her body on top mine while i was getting fucked.

When he felt filled up, yet again, he pulled out and had his stepdaughter suck him. I ate her pussy out again while she did that. While there was still the last little bit of cum, he put his amazing dick in between our mouths and we shared it, occasionally accidentally kissing each other, while he massaged each one of our titties. He rubbed his cock against her clit to please and tease her, she wanted more, but she be it would be limp.

He whispered "happy birthday, baby girl" in her ear and she just moaned out the word "daddy" as a whisper. I definitely wanted this to happen more often.

He left the room and returned shortly, "I got you something, i guess now's a better time than ever to give it to you" She bit her lip and opened the box to reveal a pink vibrator. "I've seen you masturbate baby girl, you're not very good at hiding it." She was so happy, "thank you, daddy!!" she hugged him and gave him a passionate kiss.

She turned to me and ecstatically yelled "let's use it now!" She wanted to use it first, so she put it in her pussy and moaned passionately. While i was waiting for my turn, getting so wet & fingering myself watching my girlfriend please herself, so her stepdad smirked, while zipping his pants up.

He came over to me, I rubbed his fit chest as he kneeled down on the floor. He started kissing my thighs, and then nibbling on my pussy lips, then suddenly shoving his tongue in there. I gasped as he licked & explored my whole vagina.

When my girlfriend gave me the vibrator to try, she kissed me and then he moved over to her pussy. I put the vibrator in and felt was she was feeling, it was amazing, nothing i had ever felt before. I rubbed it all over my clit before i completely took it out.

This was one of the best days of my life, and as my girlfriend quotes, her best birthday. I still get shivers from that day. I used to watch porn while i finger myself, but now i think of that moment when i'm alone and masturbate better than I ever had...

The end ;)
