It was Sunday. My parents typically left for church around 9 am and wouldn’t return until 1 or 2 pm after they had lunch and brought me something for my homebody lifestyle. It was the fourth year of hooking up with Andrew and Mark; and for the last few months, Mark and I had a perfectly aligned schedule for meeting up every Sunday. He went to work at 12 pm so he would head over to my place around 10 am and stay until 11:30.

I had a girlfriend. Surprise surprise lol. Mark and Andrew both knew and they had their own romantic relationships. But mine was beneficial to us. My girlfriend’s older sister was already out of the house living with a boyfriend. She still had her room set up and many items of clothing left in her dresser/closet. On a perfect weekend, my girlfriend asked me to go feed their dogs while they were traveling back from out of town. I entered with a spare key. While the dogs were outside, I raided her sister’s drawer. Panties, bras, cute socks, lace lingerie. I was surprised her undergarments were so colorful and sexy. Her style was mostly black and baggy clothing. I grabbed a thong, a matching color bra, some pink socks, and a pair of pajama shorts rolled up in the back of her drawer. I wish I had grabbed my heart’s worth but it would have been too obvious. I let the dogs in, fed them, and went home.

The very next day was Sunday. I had just showered and shaved. The panties fit perfectly. Large. I found my size instead of just swiping and guessing lol. The bra fit my flat breasts and the pajama shorts hugged my cheeks. My ass was halfway exposed as I pulled them up a little for extra sexiness. I admired myself in the mirror touching my soft smooth skin. Caressing my ass and squeezing my plump soft curves. Grabbing my bulge trapped behind lace panties and soft pink shorts. A text from Mark knocked me out of my trance, “I’m almost there.” I put on some boy clothes and walked out to the living room to wait.

We’re in my room. I close the door and lock it. Mark empties his pockets and sits on my bed in his work clothes. Black slacks and a button up shirt (he was a restaurant host but it was required work attire lol). I imagine him being my executive boyfriend about to leave for work. I don’t say anything. I just stand in front of him and drop my boy mode basketball shorts, exposing the pajama shorts hugging my hips. Mark picks up my shirt to get a better view and requests I turn around for him. I obliged. Turning around and sitting on his lap with my hands on his knees. He slowly starts dry humping me while grabbing my ass and hips. I move back and forth on his lap imitating my best practiced feminine movements that I had felt were his favorite from all the times we hook up. His dick is hard for me. I stand up and tell him to pull my shorts down. I have a surprise for him.

Mark peels my shorts down and I hear him gasp through a smile. My shorts fall to the floor, I sit on his lap, and adjust my new thong.

“Where did you get these?” He asks.

“Oh from my girlfriend’s sister.” She was in school with us for a year before she graduated. He knew her too.

“Hot.” He says. Mark grabs my hips and caresses my skin. I pull my shirt off to reveal the back of my new bra.

Then I turn around and get on my knees. He’s hard as a rock. I waste no time with teasing him and skip straight to sucking the tip of his cock. By my estimate we still had a solid hour before he needed to get to work. I loved to take my time on his cock. Long and cut (Andrew’s was almost as long and he was thicker and uncut). I was very familiar with his favorite moves. He preferred long slow sucking. My cheeks depressed from the suction. Making loud sucking noises since we were alone. I had been practicing my feminine whimpers and demonstrated for him.

Mark’s current favorite position was to have me prone on the floor and him absolutely pounding me from behind. My mind was melted for him. Absolutely gone. No longer a guy friend, but a soft sexy curvy girl taking her boyfriend’s cock. This extra daydreaming and willingness to give in to the other side of me, helped me push my leaking clit to the edge. Cumming while mark is mid stroke inside me shaking underneath him and moaning my lungs out with pleasure. The thong I was wearing catching my load. My post orgasm clarity had no chance. I tell Mark to go harder and to, “finish inside me!”

Mark sat on the edge of my bed catching his breath. Cock beginning to turn soft and swollen from emptying inside me. I kneel down in front of him and begin licking his shaft. I take him in my mouth. My eyes closed I can see myself perfectly in my mind. Sissy, feminine, and bred. As he gets hard in my mouth I continue slowly pleasuring him. His cum is leaking out of me and makes me tingle. My ass is covered in goosebumps. I stop sucking him and go to the bathroom to change. I cleaned what had come out of me but kept as much of his seed inside me as possible. I return to Mark with water and we make plans for the next Sunday. Including me getting an entire outfit from my girlfriend’s sister. My brain is still melted and I eagerly agree with him. Then he leaves for work and I jerk off to what just happened in the shower.
