My flatmate turned me into his Sissy Crossdressing Slut (Part 3) [24] [MM] [Bi]

*Thanks for all the feedback so far, many more stories to come!*

I’m lay on all fours, ass in the air, dressed like a slut, about to enjoy my flatmates meaty girthy cock deep in my ass when the front door is being unlocked. I couldn’t believe my luck. Its twice now that I’ve been interrupted during some of the hottest, dirtiest sex of my life. He pulls his cock quickly out of me as we both hear it. Its a feminine voice, echoing up the stairs, shouting out for a name…my flatmate. The very flatmate who seconds ago had his cock deep inside me, making me wear his girlfriends lingerie. The very girlfriend about to walk the 15 seconds it takes to make it upstairs. He panics and shoves all the things from his girlfriends bedside back into the draw. I leap, carrying my clothes out the room and dash into mine, closing and locking my door behind me, still wearing his girlfriends lingerie. She continues walking upstairs as I hear her reach the landing and walk towards my flatmates room. Thankfully the stairs and landing area has a blind spot, allowing me to dash out without anyone seeing me. She walks uninterrupted towards his room as I listen to the conversation. “I’ve had a shit night out and I wanted to stay here if that’s ok?” She says to her boyfriend. “Sure, don’t worry about it!” My roommate replies. My naughty, slutty streak returns. Imagine if he’s still wearing the condom? The very condom that’s been in my ass, wrapped tightly around his big cock, tucked into his pants. My cock gets hard again as my lubed up ass twitches to be filled. I walk over to my bed, quickly shove a buttplug inside me to quell my cock desire. I lie down in bed, refusing to take the lingerie off. I smell so slutty, so feminine. I smell of her and I loved it. I lie in bed, lights off, slowly pleasuring my wet pre-cum soaked cock and ass. I hear my flatmate talking next door, nothing of interest.

An hour or so passes, and I’m on my phone, about to wind the night down and prepare for bed. Then I hear it. A feminine groan, followed by a male groan. OMG! They’re having sex! They’re actually fucking each other! A surge of adrenaline rushes through me. Was he still wearing the condom that he used to fuck me? Was he thinking about me when fucking her? Was she submissive enough for him? Normally I try to ignore the sex noises I hear, but I wanted to know what was happening. I know he wanted to fuck me instead. Have a slutty sissy version of his girlfriend at all times available to him, able to suck and take his cock, swallow his cum on demand. He knew he fucking owned me the second he made me dress up. I continue hearing them have sex for 10 minutes or so, slowly edging my cock, pleasuring myself. He continues to pound her, groaning and moaning, cock slamming her pussy. “I’m gonna cum” I hear her say, followed by a reciprocal message from my flatmate. It was fucking hot to listen to, but she was denying my ass a cock, denying it the cum that it needed.

10 minutes later, my phone vibrates…

“…You up?” Its my roommate. What could he want? He’s already had sex though. “Yeah, what’s up?” I reply. “Got something for you I want you to have.” “One sec I’ll open the door.” He says. I stand open the door slowly as he comes out his room with something in his hand. “Take this” as he drops a used, cum filled condom slavered in pussy, cum and lube in my hand. “We’re gonna use this soon, don’t lose it.” “Sure, I reply.” a little nervously. “I really want this to happen..” He continues “…But we’ve got to be super careful, no one can find out!” I agreed, and we decided to only speak about it in person.

He grabs my hand and places it on his cock head, still leaking cum. “Try it!” He says. I place my finger, held over his cock covered in drops of cum towards my mouth. I groan in delight as he smiles in me tasting his hot, sticky and salty cum. He walks back into his room quickly as I shut the door behind him

My phone vibrates again, its him.

“Keep the outfit on…you’ll need it tomorrow ;)”…

(If anyone is interested, a BIG part 4 is coming tomorrow, but only if you’re interested) ;)
