'Lira's mouth — so close to mine — I can feel her tongue — through his cock — the movement — we are both — oh gods — what are we—'
I pulled out. Pushed Sera onto her back. Straddled her chest, my cock laying between her breasts — the pink-nippled, perkier pair, the flesh firm enough to grip but soft enough to yield. I pushed them together. Sandwiched my cock between them. Began to move.
"Mmmh—" I let the sound escape. "Hold them together. Squeeze."
Sera's trembling hands found her own breasts, pressing them inward, creating a tunnel of warm flesh that gripped my shaft as I thrust. The head emerged from the top of her cleavage with each upward stroke, red and glistening, inches from her chin.
"Lira," I said, without stopping. "Sandwich your sister's breasts. Help her."
