7 Days of Incest/Day 1/Just Rub Against Her/Take Ass/Show her Mercy

Something about those last pleas from Rose seems to reach through the haze and catch your attention. For a moment, you feel a slight pang of pity stir within you, despite the fact that she was still struggling and curring to dislodge your rod that was embedded halfway inside her tight rump. You were going to use her ass no matter what. But... a small voice at the back of your mind seemed to whisper that anal penetration was painful enough even with lube, and you had forced inch after inch of your man meat into her rear exit without it. No doubt Rose's ass felt like it was on fire. Why did she have to suffer while you were the only one who received pleasure?

Oh what the hell, You think to yourself. She's still my little sister; the least I can do is try to calm her down and make her first experience with anal somewhat bearable.

Exerting every ounce of willpower you can muster, you continue to hold your struggling sister firm while keeping your hips still to give her body time to adjust to your girth. Soon, Rose's muscles relax somewhat as she slumps over in weary defeat, sobbing hiccups escaping from her mouth barely able to be heard over the music. Only then, do you lean your head forward and rest your chin on her shoulder, right by her ear.

"Shhh. That's it, sis, you're doing good." You say, as you gently begin to pump yourself back and forth inside her again, making only small movements so as not to startle her. Luckily, you could now feel dribbles of pre-cum started to leak out of your cock and into her bowels, making your movements slightly easier; and hopefully, somewhat reducing the friction inside her bowels.

Now What?
