Sara

Becka pulls herself up and looks me in the eyes. I lean in and kiss her, my tongue slipping into her mouth. After a minute, I break the kiss and say, "First, that was a wonderful BJ. You certainly earned this." My sister starts stroking my cock again as she waits for me to continue. "Sara. She drives me nuts."

Becka says, "Mmmm. Naughty boy, I always knew you had a thing for her. She tastes wonderful."

"What? You've messed around with her?" I exclaimed, moving a hand to Becka's breast and squeezing.

She nods with a mischievous look in her eye. "Back in high school. She was fun." My mind has been replaying the blowjob and I'm definitely interested in more.

"We almost fucked at that reunion at Mom's brother's farm," I reply, leaning down and licking her nipple with a hard tongue. She moans and squeezes my cock harder. I break and say, "But we got interrupted at the pond."

As she pants her desire while I fondle one of her breasts and suck on the other, she says, "If I call you Cousin, will you fuck me?"

"You got a deal," I say, twisting and pinching her nipple.

Becka gasps, gripping my shaft tighter. "Oh, Cousin, your cock is so long and fat. I've never had a cock this big. Will it fit?" she asks in a breathy, coquettish voice a decent imitation of Sara's cadence.

"I'm sure it will fit, baby," I say with a sneer. "And it won't hurt a bit."

I push Becka against the wall, aiming my cock toward her shaved cunt. She takes the tip and guides it straight into her, tucking the head inside. I grab her hips and thrust, surging all the way into her cunt. Becka moans.

"Yes! Oh, Cousin! Your cock is a monster!" she says as she pushes her hips out to take all of me.

I start sawing back and forth inside my sister. She pulls me down for a kiss, her tongue probing deeply in my mouth. I break the kiss and whisper, "You always wanted me to fuck you, didn't you. Teasing me constantly."

Becka gasps and says breathily, "Oh, Cousin! Yes, I teased you, flashing my cleavage at you and bending over in short skirts and dresses. I've always wanted you." Becka has done those things to me since my voice changed.

I pull back a little and maul her tits, squeezing them and rolling the nipples between my fingers as I pounded her hot sex. My sister is groaning non-stop now. Her cunt is tight and so wet that there's almost no resistance to my invading member.

"Oh, fuck me, Cousin. Gimme your big fat cock. I wanna cum so hard on your cock. I wanna feel your hot jizz inside me all day long. Oh, my God, you feel so good in me."

We both grunt and moan as we fuck. It feels so good to be in my sister. Her role-playing is so hot. I kiss her hard, our tongues dancing the tango together.

Becka breaks the kiss and whispers in my ear, "Oh, Cousin! We forgot protection. Are you gonna knock me up?"

My eyes go wide as my cock suddenly explodes inside my sister's hot cunt. I can't control my thrusts, I'm pounding her so fast. She squeals as she hits her orgasm as well, her voice rising up to a new octave. "Yes, yes, yes! Shit! I'm coming on your cock, Cousin! Fill me!"

We rut and cum for a minute, before we slump, panting against the b
