I am thrilled to have Alicia’s legs wrapped around my hips as we kiss passionately while fucking each other. As far as everybody else knows, my 18 y/o sister is a prim and proper girl, a blonde looker who had been homecoming queen, had won a few bathing beauty contests and taught Sunday school once in awhile. Having her heart broken by her jerk-wad boyfriend dumping her right before the prom resulted in me, her 16 y/o brother, offering to escort her to the prom so the whole world could see how gorgeous she looked in her silver gown. After the dance, she said we were invited to an after party. It turned out she had planned to let her boyfriend fuck her ass for the first time. The next morning, she said she had been so wound up and determined to see her plans finalized that my offer to escort her made me the hero who deserved her virgin ass. It’s been a couple of months and we seize every opportunity available to fuck each other. Soon, I’ll be plunging my cock back into her tight butt, I love my big sister.
