instead of masturbating, one furiously rubs his dick on a mattress. usually he starts slow and quickens the pace after about 10 mins. Bumphing usually leads to long hard orgasms. The aftermath is usually a wet bed and a underside dickburn. Usually it leaves the person concentrated and satisfied.
Mom: What happened to your bed? Its been wet since this morning!
Son: Sorry mom, I was bumphing before I went to school, it helps my concentration.
