And it was great, I got to see a girl masturbate in full moaning, breast grabbing, panty dampening glory and she got to see me shoot a load every night. It things went on like this for a while, not much changing, until one day when I realized we’d turned a corner. I was getting ready to do my thing in the bathroom when she walked in and sat up on the counter, like usual, leaned back against the wall and spread her legs a bit, like usual. Except this night she wasn’t wearing panties. Her glistening, aroused pussy sat only feet away from me, stretch the arm, lean a bit and I’m there. I stared, stared so hard I can’t believe her pussy didn’t catch on fire.
“What?” Kelly asked nervously, “You’ve seen it before and this is just a lot easier for me.” I couldn’t answer, I was too busy stroking like a man who hadn’t cum in decades. She immediately took up her own rhythm and was soon right there with me. This was hot. It was hot an entirely different level. Not only was I staring at a real, live pussy but I was actually watching her masturbate. I had seen her do it many times before but it was always hidden by her huge grandma panties that girls back in the day wore. Now I could see her clit almost pulsing under her hand, see the slick moisture on her fingers as she plunged them in and out of her tight pink vagina. Like going from Sports Illustrated to Playboy.
Kelly could feel it too, something hungry and desperate in her eyes as she twisted, twitched and choked down moans. Her free hand shot off the counter and wrenched at her breast through the thick shirt. This could not satisfy her and she reached under her shirt to massage herself directly. This too seemed to constricting and her hand flew up from her pussy and whipped the shirt over her head. There was my sister, fully nude and masturbating furiously while staring at my dick. Her breasts were small but perky, topped with a rosy nipple that was erect and hard. They bounced erratically as she shifted her hips and moaned with pleasure. I was trying so hard not to blow it but when I saw her twist her nipple slightly and let out a moan of pain and pleasure it was too much. I almost shot a testicle out. This sent her over the edge, bucking her hips on the counter and squeezing her breast hard. We both just panted for breath for a minute before she hopped down and left without saying a word. Leaned against the wall for support, the last of my cum dripping into the toilet, I could do nothing but stare at her naked body, red and flush from her orgasm. Kelly sat on the counter, not trying to cover her breasts, not closing her legs, a contented smile on her face. Nothing moved for a while. Just two teens, exposed breasts, cock and pussy, each taking the other in completely. She looked down at her chest and blushed.
“Got a bit excited didn’t I.” Kelly said, flustered.
“I think they look great.” I blurted out. Fuck. I’m just Casanova reborn. I stammered around a bit but nothing really came out.
“Um…thanks.” She said awkwardly collecting her shirt and hopping off the counter. Kelly stopped at the door, shirt in hand and looked back at me. Not my cock, me.
“Thanks though.” She said sincerely. Being a dumbass all I could do is give her a little wave, like you might give to a friend on the other side of the room. I watched as she disappeared under the quilt. She didn’t put her clothes back on.
I jerked it twice before going to bed.
