The son-in-law feels sexual attraction towards his mother-in-law. He presses his foot against hers under the table, and she doesn't resist, continuing the conversation while entwining her legs with his. The mother-in-law worries if her husband, sleeping next to them, is waking up. The son-in-law becomes even more excited and starts touching her thighs. Slowly, he slips his fingers towards her crotch, and she finally resists... but the thrill of her father-in-law sleeping right beside them heightens their excitement.
