I asked, “How do you know how big it is?”
Debra said, “I’ve peeked before but tonight I want a good look so I know just what I’m getting into!”
I said, “Okay! But if I show you mine…”
Debra answered, “I’ll show you mine!”
I said, “Deal! Catch you later!”
After school but before our parents got home from work I went into Debra’s bedroom and dropped my pants to show her my cock. She wanted to see it hard so she sucked it. I got real hard but then she stopped and said, “Not so fast! We made a bargain for my asshole unless you’re ready to give that up!”
I replied, “I’ll wait for your butt!”
Debra then undressed. Like she said she showed me hers! She sat back on her bed and opened her legs to show me her virgin pussy then rolled back enough to show me her asshole. She got the butt plug and K-Y Jelly and showed me how she slips it in. She said that she really needs something bigger now that she has seen my cock hard.
Then she smiled and said, “Holly has a soft silicone dildo that I can borrow! It’s perfect! Get out so I can call her!”
I pulled up my pants and took another look at my almost naked sister. I got a hard-on as I realized that in a few days I’d get to butt fuck her. No girl had ever let me do that so it would be a first for both Debra and me. By no girl had ever let me I mean all two of them. Stella let me fuck her eight times last year and Judy has me fuck her six times so far this year. Judy is a lot more willing to put out.
I smiled when Holly arrived after dinner and the two girls disappeared into Debra’s bedroom for the evening.
The next morning on our way to school Debra said, “Holly thinks I’m nuts to give you my ass!”
I just smiled and said, “A deal is a deal! Isn’t it?”
Debra said, “Yes! But…Holly had trouble getting that dildo in my ass! Then as soon as the head popped in I screamed into my pillow! Do you know how much that hurt?”
I asked, “So do you want to give me your pussy instead?”
Debra said, “Fuck no! I’ll give that hole to the right guy when the time comes! And not until! Do you understand?”
I said, “Yes! I understand!”
After school on our way home Debra had Holly with her. Holly just gave me the evil eye and the silent treatment. Once we were home the two girls disappeared into Debra’s bedroom again.
When we were called down to dinner Holly glared at me and went home to eat. After dinner Debra gave me the signal to go upstairs. She told me that Holly had gotten the dildo in her ass but that it had hurt like hell. She had left it in for one minute, two minutes, and then for a full five minutes before begging Holly to take it out. She said that she was having a hard time relaxing her sphincter muscle with that dildo in her ass but that she thought that it was getting better.
The next morning on the way to school Debra thanked me for making sure that her cock sucking orgy hadn’t gotten spread all over school. Apparently my buddy that had filmed it all had told her that I had threatened to beat up anyone of the twelve guys if they spread it around. It had been a couple of days and everything was cool. However she admitted that she loved giving blowjobs and especially the taste of their cum. She was hoping that there was a way to suck cock more often but not get a bad reputation.
