While she's looking down, Sengo's still studying her. He unfastens his own jeans, slides them down as he sits on the edge of the bed - hooks his thumbs behind the waistband of his boxers and slips them down as well. His cock, slender, eight inches long, is better than half-hard already, and getting harder as he watches his little sister.

He still smells like sex - he hasn't had a chance for a shower since showing his hook-up out. There are bruise-dark hickies on the inside of his thighs.
