[M4F] Your College Boyfriend and Twin Brother

NSFW

“You home?” I call out, closing our apartment door behind me as I drop my gym bag by our shoes. I’m always cautious in the way I greet you just in case you have a friend or classmate over.

“Down here!” You reply from further inside the apartment having just skipped across the narrow hallway from the steamy bathroom to the larger of the two bedrooms in a towel, fresh out of the shower.

Following your voice I pass the smaller bedroom where I keep my clothes and computer. A room full of only my stuff helps to avoid any suspicions from our friends or parents.

“How was your day?” You ask, standing in front of the mirror and brushing your hair.

“Tried to stay awake in Greek lit and then hit the gym,” I reply before wrapping my sore arms around you and leaning over your shoulder to kiss your cheek, “yours?”

“Poli sci, lunch with Becca, and then a suuuper boring dark ages lecture.”

I slide my hands down the back of your towel until I’m groping your ass with both hands while grinning in the mirror at you.

“Sssstttttooooooppppp,” you whine while turning to halfheartedly push me away, your small hands on my chest, “you stink… go have a shower first.”

“Only if you join me…” I grin, reaching out to undo the towel wrapped tightly beneath your arms.

You bite your lip and let it fall silently to the carpet, now standing naked and freshly shaved in front of me, “Ugh… mom texted me like three times today, I think we’re going to have to have them over for dinner this weekend.” You scoff.

I exhale hard as I sit down on the bed looping my waistband with both hands to pull down my shorts and expose my already semi hard cock, “Fuck… we’ve barely had any time together this week… thought we could push them off until next weekend.”

“Nope…” you reply while simultaneously wrapping your small soft hand around my thick shaft and climbing onto the bed, putting your knees on either side of me, “don’t want to piss them off and have them threaten to stop helping us with rent.”

I can only nod as you slide me inside of you, still not having gotten anymore used to how unbelievable it feels to be inside my own twin sister. My hands instinctively move to your hips as you position yourself to ride me, “we’ll just have to make the most of tonight.” I whisper through clenched teeth while looking up at you.

“You mean fuck each others brains out so good we’ll be able to keep our hands off each other in front of mom and dad?”

“Exactly.” I reply bucking my hips up to drive my engorged head deeper into your wet pussy as our bed begins to creak.

….

Looking to roleplay an established relationship between a twin brother and sister living together and going to the same university/college.

We can discuss kinks and where we actually want to start… doesn’t have to be right where I left things!

Prefer chat!
