My sister was really nervous about going on her first date. She had finally gotten the courage to ask her crush out and he agreed to get dinner with her after school that Friday. I had agreed to be her wingman mostly cause I was tired of having to listen to her panicking through the thin wall between our rooms. Since I’d been dating my girlfriend for a few months now, Sis wanted me to give her some guidance on what to do and what to expect on her first date. After talking her through most of it, she asked if we could do a practice run. We sat at the kitchen table and I pretended to be her crush as she practiced. After a second go, she seemed ready to me.
Of coarse, being her overly worried self, she insisted that we practice a full date, start to finish, actually going to the restaurant at night. I figured it would be better than having to endure her panic attacks for the rest of the week so I begrudgingly agreed. That night, I drove my car around front so she could practice being picked up. Things started well as she got in with minimal tripping over her words as she addressed me by his name.
As we arrived at the restaurant and sat down at our table, she seemed to really get into the role-play. I could tell that she was finally starting to get comfortable and confident in herself as her flirting picked up. After we got our food, things started to get a little too heated for my comfort and I tried to steer her back to being less forward. When she pulled her shirt neck down to show me she wasn’t wearing a bra, I broke character and told her to stop while trying not to attract attention. She kept going, still calling me by his name as she expressed how much she wanted him. Before I knew it, she had gotten under the table and was pulling my cock out! There was nothing I could do to stop her without letting everyone else see what she was doing. She swallowed my cock until I was about to release and then got up. I pulled my shirt over my dick as she dragged me into the bathroom.
“I need your thick cock inside my pussy!”
“Sis, stop we can’t do this!”
“I wouldn’t have guessed that you were so into incest play, Danny.”
“I’m not Danny, I’m your brother! This is going to far, we have to stop!”
“Whatever you say ‘bro’, now stick that dick in your ‘sister’s’ wet pussy!”
I felt my sister’s lips spread for me as she pulled in my bare cock. I couldn’t believe what she was doing. Had she lost her mind?
“Oh God, you’re so much bigger than I thought you would be!”
She was almost unbearably tight and her sopping juices barely provided enough lubrication as she began thrusting her hips back and forth around me. I felt myself loosing control as my body slowly began returning her motions. My girlfriend had never felt this good! Giving in to her pleasures, I resigned to fuck my sister as she trembled on my cock. Before I came, she pulled out and finished me off with her throat.
We cleaned up and returned to our table, left enough money to cover the bill plus tip, and walked out the door without even finishing our meal. I drove us home as she jerked me off and before long, I was lying on her bed as she rode my cock. I couldn’t control myself as we fucked and made out like nothing else in the world mattered.
“Sis, I’m gonna cum!”
“I’m not on the pill, put it all deep inside me! I want your babies, Danny!”
“Sis, wait, stop! I can’t! My girlfriend… Fuck!”
Pushing herself as far down on my cock as she could, I felt my head pressing against her cervix as I came the biggest load of my life in my sister’s fertile womb! A few minutes passed as we lay together panting as we recovered from our orgasms. Finally, she lifted herself from me.
“Oh wow! I didn’t know dating would be so much fun! Thanks for helping me Bro, I think this practice run went really well!”
“Fuck, Sis! You made me cum inside you!”
“Relax, we were just roleplaying! It’s not like you actually cheated on your girlfriend or really had sex with me. It was all pretend!”
“Sis, my cum is dripping out of you.”
“Yeah, you’re really good at roleplaying! Although, I really don’t think Danny has an incest fetish. His sister is kinda ugly.”
“Please tell me you were just ‘roleplaying’ when you said you were off the pill!”
“Well by contraceptives are effective for a month at a time so I had to get off them a few weeks ago to make sure I would be ready for my date with Danny.”
“What!?”
“Calm down, Bro. You didn’t really cum inside me, we were just practicing! But… I think we should try again. I fumbled my words a bit in the beginning and I didn’t even finish my food. I don’t want Danny to think I’m awkward or wasteful so I need to make sure I don’t mess up those parts! We still have two more days before Friday so we can practice again tomorrow.”
“Sis, I can’t believe you…”
“We got school tomorrow and it’s getting pretty late. Come on, get out of my bed. I can’t sleep with my brother! That’d be weird.”
