Chapter 10: Guys and Girls

About a week later, Jane told me how she got her brother to fuck her. It’s kinda funny, and I’m going to tell it from her point of view since it gets fucked up otherwise. So, here ya go.

My boyfriend, Zack, the most amazing man I will ever know, has managed to have sex with every member of my family. He’s bi, so it’s no big deal. I suppose I should be mad I was the last one, but under the circumstances, coming in last got me first. So, at this point, dad and I have had sex, he’s being really paranoid, and I know he wants it again, but we’ll see. I had amazing first-time sex with my mom breaking her girl-sex cherry. Look out, Zack’s mom, my mom, is on the prowl. That leaves my poor, clueless girl-virgin younger brother. Ha ha. This is going to be fun.

Zack told me that he got my brother into sneaking mom and my panties and using them to masturbate. Ha, halfway there already. So, I bate in my panties every morning, getting them nice and wet. Some mornings, I had Zack’s load there too. Oh, so good. They all disappeared back later, though. Today was different. When I went into the bathroom to check the hamper, my thong was there, the wet one I left for Dereck, but now it had his cum on it. Not much. He must have shot before he could move it. I put it back on and went down for breakfast in just my thong and tee shirt. No big deal since both my parents have seen me naked recently but don’t know the other has had sex with me. Confusing, huh? Anyway, they’ll act like it’s nothing.

Dereck’s at the tall kitchen table when I come down in my long tee shirt. He’s talking to dad. I brush his body to get his attention and then bend over to get the milk out of the fridge. I hear him snort and the slop of his cereal going back into the bowl. Mom scolds him. I stand and turn. As mom and dad look away, I mouth the words, ‘thank you.’ Oh, fuck did my brother’s face go red.

Well, everybody did their thing for the day, and at bedtime, I left a note on my brother’s bed. ‘cum in your briefs and leave them in the bathroom. I’ll leave my cummy thong. I’ll wear yours if you wear mine.’ So fucking kinky. Oh, I came so hard in that pink thong. It was soaked.

I always wake first. I left my thong, wet and still warm, in the bathroom, did my thing, and returned to my room. I heard Dereck go in, do his thing and leave. Now to see what happened.

My thong was gone. White briefs lying on top of the hamper. I could see the front was wet. I held them to my face. The pungent scent of man juice, my sibling’s cum. I quivered as I slipped them on, letting the soaked gusset sit against my wet pussy. It’s going to be a good day. I put on running shorts over Dereck’s briefs and a tee. Down in the kitchen, as mom and dad weren’t looking, I caught his eye and rolled the waistband down. His eyes bugged, and his mouth fell open. I nodded toward his shorts. He blushed, looked at mom and dad, then pulled his shorts down. He was wearing my thong. Almost there.

That night we had fun. Dereck seemed a little looser. I’d flash the waistband of his briefs. He’d smile nervously and do the same with my thong. He looked like he was half-hard all night.

At bedtime, he disappeared into his room. Oh, no, no. Not getting away with that. As his door shut. I opened it and slipped in. Dereck looked up in shock, his shorts open, my thong visible. “Sis, what are you doing?” His voice almost quivering. I leaned against the door.

“You have a good day, bro?”

Poor Dereck blushed so hard. His voice shaky. “Ummmm, yeah, I guess.” His hand clenched his shorts. I think he wanted to keep this kinda secret. Too bad. I rolled down the waistband of my shorts. “Thank you, Dereck. I didn’t think you’d do it.”

Dereck fidgeting around. “I almost didn’t. It’s weird.”

“I’ve been leaving you my wet panties. You seemed to like them.”

“Um, I’m sorry, sis. That was wrong.”

“Dereck, I know what you do with them. I like it. I like knowing my brother thinks I’m hot.”

Dereck, the reality sinking in. “It’s wrong, sis. But, yeah, I like it. I thought you were crazy about today, almost didn’t do it. I mean, this is my sister. But you smell so good, and you asked.’

I pushed the waistband of my shorts down just a little, showing my brother’s white briefs. I ran my finger along the waistband. “So, you masturbated and shot your cum in the gusset. Then left them for your sister to find.”

Dereck getting braver now. “Yeah, but you asked.

“I did, and I’ve really enjoyed wearing them all day with your cum up against my pussy.”

Dereck stared, his breathing deeper, reacting to my slutty talk.

“So, I guess I should return them to you. I apologize. I had to masturbate in them once or twice.”

As Dereck stared, I shoved my shorts down and kicked them away. “Wha..what are you doing, sis?”

I looked him right in the eyes. “I’m returning your underwear, and I’ll want mine back too.”

I slipped my fingers under the elastic and pushed. His are a little big on me, so they fell right down to my knees. I had a short tee on, so my brother had no problem seeing my shaved pussy. He was gasping. I leaned over, picked them up, and moved closer, holding them out to him.

“Dereck, they’re still warm. Our cum is in them.”

Not paying attention, Dereck used the hand holding the shorts to take his underwear back. He moaned quietly as his hand felt the warmth, and his shorts dropped to his feet.

His nice hard cock stuck out of my thong, which I noticed had a lot of wetness in the front. Dereck came to his senses and tried to bend to get his shorts. I put my foot on them. “Too late, bro. I’ve already seen you. Now you get the rest”. I flipped off my tee shirt.

We stood, nearly touching, face-to-face. Me smiling, Dereck still stunned, his cock dripping precum. I reached out and touched his face. “May I have my thong panty back?”

Half in a trance, Derek put his fingers in the waistband and slowly pushed my thong down while looking into my eyes. At his ankles, he stepped out and bent, picking it up and holding it out to me. I took it and pressed it to my face. “Mmmmm, smells like you, like us. Did you masturbate in these?”
