"Gains"

A Few weeks pass as you start going to the gym with Megan. Since you're dressing up as a girl everytime your sis starts giving you your own girl clothes. You get your own panties, shorts, leggings, bras, tops. However, Storing all these things in your dresser is taking up too much space. You decide to start removing your boy clothes that you no longer wear into storage, only keeping your favorites in your dresser.

Megan barges in, "Hey, we're going to the gym, get dressed bestie <3"

Awesome, I was dying for an orgasm. After going to the gym so much, using that dildo has become a real bad habit. I'm not even sure I could cum normally anymore.

Dressed up in cute workout girl clothes and a wig, you and megan head to the gym. Working out started like it has been for the past few weeks. Shakes before, dressing up as a girl, doing the same workouts as Megan.

Once you headed to the shower for your well deserved orgasm, the dildo you've been dying to use was taken away. UGH!! I can't believe they took away my dildo, I'm literally leaking precum. "well if you wanna cum, I know a way..."

What way? I don't know if anything but a dildo will do it for me anymore. "Well I got the next best thing" Megan pulls you into family shower room. "I used to make some money here during the summer. Since no families actually come here, we use the family room to have sex. Guys come in, pay the girls, and we fuck each others brains out. Don't worry about it being real dick and Just try it, if you don't like it then don't do it again k :)"

Dying for your after workout orgasm you give in. Walking around the family showers, you see this really buff guy showering naked with a huge dick. "Right here bestie! This guy will make you cum like crazy. I usually fuck him everytime I see him but I'll let you have him today :P"

Tapping on his shoulder, Hey would you like to fuck me? He looks you up and down looking at your cage and ass. "Yes I would sissy bitch"

He slaps your freshly worked out ass. You can't help but get turned on by his aggressiveness. He pushes you against the wall with your butt sticking out. You feel him touch the outside of your cage. "I'm just gonna use this as lube for you sissy" He starts lubing you up with your own precum.

FUCK this feels so good, you feel his cock on the inside of your thighs while he's lubing your hole up with your own precum. Feeling good like the dildo on the wall you instinctively start pushing your ass into his fingers. "Someone's dying for dick aren't you sissy?"

yyyeeES~!! While answering him he pulls you into his cock, slowly and all in one go. Fuck! He's lifting you by your hips with his hands and your asshole with his dick. On your tip toes you can't help but let his dick and hands hold you up.

OMG this dick is huge. I think it's even bigger than that dildo I've been using here, and longer! Leaking cum like crazy you start pushing into his dick like the dildo you've been using. Fuck this feels so good. Lost in pleasure, he suddenly pulls you completely on his dick as something hott fills you up. THIS IS A CREAMPIE!! So turned on from the creampie you start cumming. Your asshole pulsing on his dick as you cum. "Your asshole is so slutty it's milking me like a slut." He pulls out his cock and you lean against the wall for support.

"That was great, here's your money sissy, I look forward to next time" He hands some money over to your sis.

You weren't kidding how good his dick was sis. There's just one thing that's weird...that dildo was the perfect size to prepare my asshole for this dick.

"Oh I know, It's my dildo after all"
