In 'Soloboy' fashion, our anonymous hero finds himself alone with his girlfriend's laundry, her thong tanga calling his name. He can't help but run his fingers along the lacy edge, feeling the heat of her recent presence. His cock stirs as he imagines her wearing it, her ass filling it out. He gives in, stroking himself, building a rhythm as he pictures her dancing in it, teasing him. The tanga becomes his focal point, his fantasy, as he brings himself to a messy, satisfying conclusion.
