Terri and Mona abruptly stopped talking as soon as I stepped onto the deck. When two girls stop talking as soon as you show up, that's never a good sign.
That's Terri my girlfriend and her older sister Mona. They were both stretched out on blankets, soaking up the sun in their bikinis... but I knew Terri had only very faint tan lines around her breasts, so I had a feeling they'd both been topless before they heard my car pull up outside. Mona was a couple of years older than Terri, she'd been in my class through most of high school, and I'd always wondered what her breasts looked like.
Gotta learn to come in more quietly
, I told myself.
"What's the smirk all about?" Terri asked. "Naughty thoughts?"
"Well, what were
you guys
talking about that you stopped so suddenly?" I countered, kicking off my shoes, pulling off my shirt, and lying a blanket out on the ground to join them.
"What's it worth to ya?" Mona asked me. I noticed a couple of empty wine coolers on the ground between them: not enough to get anybody drunk, but enough, especially on a warm day, to make them both pretty mellow.
"Well, that depends on how good it is."
"Oh, knock it off," Terri said to her sister.
"It's really good," Mona said in a stage whisper, giving me a wink.
Whatever it was, Terri obviously didn't want me to hear, so of course I was intrigued. "Okay, what do you want?" I had a feeling she was going to ask me to rub suntan lotion on her back, which I guess Terri would have been okay with.
"Lie down here with us," she said.
"Um... I already am?"
"We're not wearing shorts. Take yours off."
I looked over at Terri. She wasn't sure about this. "It's not as if I haven't seen him in his underwear before," Mona reminded her. Which was true: she'd accidentally walked in on us a couple of times in Terri's room, but fortunately both times we'd only been in the early stages of foreplay.
"Whatever," Terri said.
"Fine," I said, pulling off my shorts. My boxer-briefs had a lot more material than their bikini bottoms, but I had the start of a pretty decent boner to hide. I decided to lay on my front. "Okay, what's the big secret? What were you talking about?"
"Um... you," Terri said.
"Anything interesting?" I asked.
"Terri said you're good in the sack," Mona said.
"Okay, that's enough," Terri told her.
"Girls talk about that?" I asked. And yeah, of course I was pleased.
"Oh yeah, she says you make her cum almost every time."
"Jesus, Mona," Terri said.
"What's wrong? It's not as if he doesn't know. Assuming you're telling the truth. Is she telling the truth? Do you always make her cum first?"
"I guess."
"You either do or you don't. Honestly, I've rarely been with a guy who ever does that, much less always. Maybe I'm a little jealous "
"Maybe you're just frigid," Terri teased.
Mona gave her the finger, accompanied by a rude gesture. "I'll have you know I can cum all over the place, and cum good. Just usually alone, is all."
"TMI," I shouted.
"Well," Mona said, "still sounds like bullshit to me. Or wishful thinking, at least."
"Believe it or don't, I don't care," Terri said, sounding annoyed now.
"Okay, then prove it."
"What do you mean, prove it?"
"Go ahead, fuck my sister," Mona told me.
"No way," I said, at the same time Terri was saying "Not even if you were serious."
Mona sat up and took off her top. "Okay," she said, does this say 'serious' to you?" I tried not to react audibly to the fact that Mona had amazing breasts. I mean I'd suspected as much, because I'd seen her in a bikini and tight shirts in the past, and her younger sister's breasts were pretty damn nice, but... wow. "Come on, let me see."
"Even if we wanted to," Terri said, "I don't think I have any condoms upstairs. Did you bring any with you?" she asked me.
Was she actually considering this, or just naming reasons it wasn't going to happen? "No," I said.
