[M]y girl[f]riend’s sister surprised me

A recent GW story reminded me of something similar that happened to me post college.

Was staying at my girlfriend’s house after college. I had gotten sick, so while she was at work, I slept in. Still burning up with a fever, I tried taking a bath. The only other person in the house was her sister, Brenda, who was in her first year of college. She’d always had a thing for me, since early high school, despite having the same boyfriend since 6th grade. Would always make little comments like ‘hey sexy’, would rub up against me, her hugs would last a little longer than needed, that sort of thing.

So I was in the tub trying to cool down, and she knocked on the door. “I have to pee!” she calls through the door. The problem was that the house was perpetually in repair, and this was the only working bathroom in the house, on top of that, there wasn’t even a shower curtain, hence the bath instead of a shower. I tell her I’m in the tub, and she promises she wouldn’t look, if I promised her the same. I tell her that I covered myself up and she can come in. I reach for a hand towel and cover my midsection, then closed my eyes and told her to come in, but to hurry.

I hear the door open and then a rustling of clothes, then she says I can open my eyes. There she is, sitting on the toiler, her legs pressed together tightly, white panties at her ankles, and a white spaghetti strap top, with no bra.

“Brenda!”

“It’s ok, you can’t see anything! I’ll be done in a second.”

“Still, you should be wearing more if you’re going to walk in here.”

I closed my eyes and tell her to tell me when she’s done. A minute later I hear the flush and she says ‘OK’ and I hear the door open and close. I open my eyes and suddenly the door opens again. “Ooops, I forgot to wash my hands”. She stands at the sink, facing away, and turns on the faucet.

The view of her from behind was outstanding, short top exposing her waist, tight white string bikini panties. Unexpected and very appealing.

“I told you that you should put more clothes on when walking around me.”

“It’s ok, it’s just like I’m wearing a bikini. And you liked my bikini when you saw it, remember?” I thought back for a second and yes, she looked quite good earlier in the summer.

She turned around, leaned back against the ink as she dried her hands off. Then she tugged her panties up a bit and added, “See? Just like a bikini.”

“Umm, not really. You can’t see through a swimsuit. I can see through both your top and bottom.” A dark patch was clearly visible thru the white triangle of cloth between her thighs, and her nipples were just as visible through her top.

“Close enough,” she scolded me. “We’re basically family. I walk around my family like this all the time, so what’s the big deal?”

Her words were not matching her thoughts, though, she stood there knowing that she was purposely flaunting herself in front of me, hoping to get a reaction out of me. And it was working.

I began to get hard, and she noticed the towel beginning to move in the water.

“Oh my god! Are you getting a boner?” she pretended to gasp. I could tell she was secretly pleased. “Because of me?” and she looked at herself up and down with false modesty.

Her gaze turned into a stare as she focused on the tent beginning to form from the towel. “That’s so sexy!”

She met my eyes for a moment, and said “When I was sitting down, and you had your eyes closed, I wanted to lean over and lift it off you.” She giggled. “My boyfriend’s the only one I’ve ever seen. I wanted to see yours.”

She stepped forward and sat on the edge of the tub, and repeated, “I want to see yours.” Without waiting for an answer, she reached in the water toward the bottom edge that was laying on my thigh. In my feverish fog, I was too slow to stop her. Suddenly I was uncovered, the towel in her hand. “Ooooo,” she cooed as she stared at my rigid cock. “I have so many questions!”

“What does it feel like when you’re hard? Does it feel good just to be hard? What is it like to walk around with it hard?” She stared intently. “Can I touch it?” She didn’t wait for an answer for that last question, she reached into the water again and wrapped her fingers around it, like grabbing a door handle. “I like the way it feels.”

At this point I wasn’t going to be able to stop her, nor did I have the willpower to do so myself. While the rest of me was an aching me, my cock felt like it was part of a different body, and her touch felt so good. I had to let her continue.

She kept asking questions. “What does this feel like?” as she let go and then traced her fingertip down the shaft.

“You know how your nipples feel when they’re hard? I guess it’s sort of like that. They like stick out from your body like they’re a separate part of you. and if you brush up against something it feels really good. Something like that I guess.”

She grabbed me again and squeezed the shaft. “I love this! How do you not play with yourself all the time?” I laughed. “Probably the same way that you don’t feel up your tits constantly. I would!”

She laughed back, and cupped the knob with her palm, then traced the tip. “What’s it like when you come? It must be amazing to feel it shoot out.”

I thought for a second as she ran her fingertips over my cock, slowly, under the water. “You know how it feels when you have to pee really bad, and then you can suddenly go? Imagine that you were peeing through your hard nipples. Maybe something like that?”

She considered that answer as she started to stroke me. “Could you come under water?” Her eyes opened wide as she realized what she just offered. “Do you want to?” She slipped one leg over the edge of the tub, so she was straddling it, and put her foot in the water on the farside of my legs, so she could reach closer. I could see her grinding against the tub, too, her panties tugged up tight against her pussy.

“I’m so horny right now!” she moaned, and almost unconsciously put her hand in between her thighs, and began rubbing as she pumped me harder. “I can’t stop myself!”

Watching her rub herself, combined with the unexpected hand work, sent me over the edge almost instantly. My legs stiffened and I said “You asked about coming under water? I’m going to right now…” She watched intently as she felt my cock tense, and then start to throb, milky globs spurting through the water. I groaned as the orgasm rolled through my body. Streams of cum floated through the water around my groin and up over my stomach.

She kept pumping me, trying to squeeze another drop out, then another. I leaned my head back, enjoying the post-climax daze. She suddenly became aware that she’d been in the bathroom for a long time, that she better get out in case anyone came home.

“That was so exciting!” as she stood up and wiggled a bit in front of me, showing off. “I hope I get to see your boner again. Then she leaned over and pulled down her top for a second. “I hope I give you one!”

She stepped out of the tub, wiped her foot off, and disappeared. I closed my eyes, my fever suddenly hotter than ever. But I didn’t care.
